I would like to do something like Grouping with a bottomRowCalc but having the visibility of the rows of data being optional. Currently I'm using getData('active') to add up the values and row.update() on the "sum" row with the values. But if I filter out the data rows, they wont appear in the getData('active'), so I'd have do a getData().forEach(row => {}) and manually check for another field flag I guess to see if it should be included in the sum.
It sure would be nice if I could continue to use getData('active') but set row.visibility(false) on rows I dont want to show, but still be in active ?
Is answering your own question a sin ?
Anyway, for posterity, in case anyone else wants to do this :
rowFormatter:function(row) {
let display = 'inline-block';
if (some_condition) display= 'none';
row.getElement().style.display = display;
return true;
}
rowFormatter: function(row){
var row_data= row.getData()
console.log('row_data is...',row_data);
if (row_data === 'yes'){
const children = row.getElement().childNodes;
children.forEach((child) => {
child.style.backgroundColor = 'red';
})
}
else (row_data === 'Upcomming')
{ let display = 'inline-block';
display= 'none';
row.getElement().style.display = display;
return true;
}
},
In this case you will miss s.r. with the row

I am using the Tabulator plugin and am using the editorParams function to select from a list of options. If a value isn't selected (eg: Cancelled) I want it to revert to the old (previous) cell value and do nothing, but calling cell.setValue() keeps retriggering the cellEdit function and it gets stuck in a loop.
table.on('cellEdited', function(cell) {
var cellOldValue = cell.getOldValue();
var cellNewValue = cell.getValue();
var row = cell.getRow();
var index = row.getIndex();
if (cellNewValue == 'none-selected') {
cell.setValue(cellOldValue);
} else {
if (confirm('Are you sure?')) {
// ok, do something
} else {
cell.setValue(cellOldValue);
}
}
});
This just keeps triggering the prompt. Any solutions, thank you?
http://tabulator.info/examples/4.1
The Editable Data example above shows the use of a custom editor for the date field (example in the link is DOB). Similar examples exist in earlier tabulator versions as well as here and Github. The javascript date picker that results works perfectly for most users but not all (even if also on Chrome). So the alternate approach often attempted by the users is to try and enter the date directly into the cell. But unfortunately this is problematic --in the same way it is with the linked example. Changing the month and day isn't too bad -- but directly changing the year is very difficult. Does anyone have a potential solution? I've explored everything from blur/focus/different formats/"flatpicker"/etc - but I'm coming up empty.
The best approach to get full cross browser support would be to create a custom formatter that used a 3rd party datepicker library, for example the jQuery UI datepicker. The correct choice of date picker would depend on your needs and your existing frontend framework.
in the case of the jQuery datepicker the custom formatter could look something like this (this example uses the standard input editor, you will notice in the onRendered function it turns the standard input into the jQuery datepicker):
var dateEditor = function(cell, onRendered, success, cancel, editorParams){
var cellValue = cell.getValue(),
input = document.createElement("input");
input.setAttribute("type", "text");
input.style.padding = "4px";
input.style.width = "100%";
input.style.boxSizing = "border-box";
input.value = typeof cellValue !== "undefined" ? cellValue : "";
onRendered(function(){
input.style.height = "100%";
$(input).datepicker(); //turn input into datepicker
input.focus();
});
function onChange(e){
if(((cellValue === null || typeof cellValue === "undefined") && input.value !== "") || input.value != cellValue){
success(input.value);
}else{
cancel();
}
}
//submit new value on blur or change
input.addEventListener("change", onChange);
input.addEventListener("blur", onChange);
//submit new value on enter
input.addEventListener("keydown", function(e){
switch(e.keyCode){
case 13:
success(input.value);
break;
case 27:
cancel();
break;
}
});
return input;
}
You can then add this to a column in the column definition:
{title:"Date", field:"date", editor:dateEditor}
I couldn't get what Oli suggested to work. Then again, I might be missing something simple as I am much more of a novice. After a lot of trial+error, this is the hack kind of approach I ended up creating -- builds upon Oli's onRender suggestion but then uses datepicker's onSelect the rest of the way.
The good: The datepicker comes up regardless where in the cell the user clicks -- so the user is less tempted to try and enter manually. If the user happens to try and enter manually, they can do so.
The less-than-ideal: If the user does manually enter, the datepicker won't go away until he/she clicks elsewhere. But not a showstopper.
//Date Editor//
var dateEditor = function(cell, onRendered, success, cancel, editorParams){
var cellValue = cell.getValue(),
input = document.createElement("input");
input.setAttribute("type", "text");
input.style.padding = "4px";
input.style.width = "100%";
input.style.boxSizing = "border-box";
input.value = typeof cellValue !== "undefined" ? cellValue : "";
onRendered(function(){
$(input).datepicker({
onSelect: function(dateStr) {
var dateselected = $(this).datepicker('getDate');
var cleandate = (moment(dateselected, "YYYY-MM-DD").format("MM/DD/YYYY"));
$(input).datepicker( "destroy" );
cell.setValue(cleandate,true);
cancel();
},
});
input.style.height = "100%";
});
return input;
};
I use datepicker from bootstrap, this is my code
var dateEditor = function (cell, onRendered, success, cancel, editorParams) {
//create and style input
var editor = $("<input type='text'/>");
// datepicker
editor.datepicker({
language: 'ja',
format: 'yyyy-mm-dd',
autoclose: true,
}).on('changeDate', function() {
if(editorParams != 'row'){
editor.trigger('keyup');
}else{
editor.trigger('change');
}
});
editor.css({
"padding": "3px",
"width": "100%",
"height": "100%",
"box-sizing": "border-box",
});
editor.val(cell.getValue());
onRendered(function(){
editor.focus();
});
editor.on("blur", function (e) {
e.preventDefault();
if(editor.val() === '') {
success(cell.getValue());
}
else {
//submit new value on change
editor.on("change", function (e) {
success(editor.val());
});
}
});
return editor;
}
I can't find any code example or docs that answers this:
Achieve almost complete infinite scroll -> unknown # of items, but there is a finite amount that may be infeasible to compute beforehand - e.g. at some point the list needs to stop scrolling
Can I trigger first load of data from within InfiniteScroller/List - it seems you need to pass in a data source that is populated with initial page
I am using this example:
https://github.com/bvaughn/react-virtualized/blob/master/docs/creatingAnInfiniteLoadingList.md
and:
https://github.com/bvaughn/react-virtualized/blob/master/source/InfiniteLoader/InfiniteLoader.example.js
along with CellMeasurer for dynamic height:
https://github.com/bvaughn/react-virtualized/blob/master/source/CellMeasurer/CellMeasurer.DynamicHeightList.example.js
The docs for InfiniteLoader.rowCount say:
"Number of rows in list; can be arbitrary high number if actual number is unknown."
So how do you indicate there are no more rows.
If anyone can post an example using setTimeout() to simulate dynamic loaded data, thanks. I can likely get CellMeasurer working from there.
Edit
This doesn't work the way react-virtualized creator says it should or the infinite loading example implies.
Calls:
render(): rowCount = 1
_rowRenderer(index = 0)
_isRowLoaded(index = 0)
_loadMoreRows(startIndex = 0, stopIndex = 0)
_rowRenderer(index = 0)
end
Do I need to specify a batch size or some other props?
class HistoryBrowser extends React.Component
{
constructor(props,context,updater)
{
super(props,context,updater);
this.eventEmitter = new EventEmitter();
this.eventEmitter.extend(this);
this.state = {
history: []
};
this._cache = new Infinite.CellMeasurerCache({
fixedWidth: true,
minHeight: 50
});
this._timeoutIdMap = {};
_.bindAll(this,'_isRowLoaded','_loadMoreRows','_rowRenderer');
}
render()
{
let rowCount = this.state.history.length ? (this.state.history.length + 1) : 1;
return <Infinite.InfiniteLoader
isRowLoaded={this._isRowLoaded}
loadMoreRows={this._loadMoreRows}
rowCount={rowCount}
>
{({ onRowsRendered, registerChild }) =>
<Infinite.AutoSizer disableHeight>
{({ width }) =>
<Infinite.List
ref={registerChild}
deferredMeasurementCache={this._cache}
height={200}
onRowsRendered={onRowsRendered}
rowCount={rowCount}
rowHeight={this._cache.rowHeight}
rowRenderer={this._rowRenderer}
width={width}
/>}
</Infinite.AutoSizer>}
</Infinite.InfiniteLoader>
}
_isRowLoaded({ index }) {
if (index == 0 && !this.state.history.length)
// No data yet, force load
return false;
}
_loadMoreRows({ startIndex, stopIndex }) {
let self = this;
for (let i = startIndex; i <= stopIndex; i++) {
this.state.history[startIndex] = {loading: true};
}
const timeoutId = setTimeout(() => {
delete this._timeoutIdMap[timeoutId];
for (let i = startIndex; i <= stopIndex; i++) {
self.state.history[i] = {loading: false, text: 'Hi ' + i };
}
promiseResolver();
}, 10000);
this._timeoutIdMap[timeoutId] = true;
let promiseResolver;
return new Promise(resolve => {
promiseResolver = resolve;
});
}
_rowRenderer({ index, key, style }) {
let content;
if (index >= this.state.history.length)
return <div>Placeholder</div>
else if (this.state.history[index].loading) {
content = <div>Loading</div>;
} else {
content = (
<div>Loaded</div>
);
}
return (
<Infinite.CellMeasurer
cache={this._cache}
columnIndex={0}
key={key}
rowIndex={index}
>
<div key={key} style={style}>{content}</div>
</Infinite.CellMeasurer>
);
}
}
The recipe you linked to should be a good starting place. The main thing its missing is an implementation of loadNextPage but that varies from app to app based on how your state/data management code works.
Can I trigger first load of data from within InfiniteScroller/List - it seems you need to pass in a data source that is populated with initial page
This is up to you. IMO it generally makes sense to just fetch the first "page" of records without waiting for InfiniteLoader to ask for them- because you know you'll need them. That being said, if you give InfiniteLoader a rowCount of 1 and then return false from isRowLoaded it should request the first page of records. There are tests confirming this behavior in the react-virtualized GitHub.
The docs for InfiniteLoader.rowCount say: "Number of rows in list; can be arbitrary high number if actual number is unknown."
So how do you indicate there are no more rows.
You stop adding +1 to the rowCount, like the markdown file you linked to mentions:
// If there are more items to be loaded then add an extra row to hold a
loading indicator.
const rowCount = hasNextPage
? list.size + 1
: list.size
I'm relatively new to js and now have to implement a handsontable into our project.
This worked well so far, but I am hitting a roadblock with globalization.
Basically, we use comma as a decimal seperator, but when I try and copy something like "100,2" into a cell designated as 'numeric,' it will show as 1002.
If the same value is entered in a cell designated as 'text' and the type is changed to numeric afterwards, the value will be shown correctly.
For this I already had to add 'de' culture to the table sourcecode.(basically copying 'en' and changing the values currently relevant to me.)
numeral.language('de', {
delimiters: {
thousands: '.',
decimal: ','
},//other non-relevant stuff here
When I copy the values directly from the table and insert them to np++ they show as 100.2 etc. However, when inserting them into handsontable the arguments-array looks as follows:
[Array[1], "paste", undefined, undefined, undefined, undefined]
0: Array[4]
0: 1 //row
1: 1 //column
2: "100.2" //previous value
3: 1002 //new value
Here's what I have tried currently:
hot.addHook("beforeChange", function () {
if (arguments[1] === "paste") {
hot.updateSettings({
cells: function (row, col, prop) {
var cellProperties = {
type: 'numeric',
language: 'en'
};
return cellProperties;
}
});
//hot.updateSettings({
// cells: function (row, col, prop) {
// var cellProperties = {
// type: 'text',
// };
// return cellProperties;
// }
//});
}
}, hot);
hot.addHook("afterChange", function () {
if (arguments[1] === "paste") {
ChangeMatrixSettings(); //reset cell properties of whole table
}
}, hot);
I hope I've made my problem clear enough, not sure if I missed something.
Are there any other ways to get the correct values back into the table? Is this currently not possible?
Thanks in advance.
You asked more than one thing, but let me see if I can help you.
As explained in handsontable numeric documentation, you can define a format of the cell. If you want '100,2' to be shown you would format as follows
format: '0.,'
You can change that to what you really need, like if you are looking for money value you could do something like
format: '0,0.00 $'
The other thing you asked about is not on the latest release, but you can check it out how it would work here
I have since implemented my own validation of input, due to other requirements we have for the table mainly in regards to showing invalid input to user.
function validateInputForNumeric(parameter) {
var value = parameter[3];
var row = parameter[0];
var col = parameter[1];
if (decimalSeperator === '') {
var tmpculture = getCurrCulture();
}
if (value !== null && value !== "") {
if (!value.match('([a-zA-Z])')) {
if (value.indexOf(thousandSeperator) !== -1) {
value = removeAndReplaceLast(value, thousandSeperator, ''); //Thousandseperators will be ignored
}
if (value.indexOf('.') !== -1 && decimalSeperator !== '.') {
//Since numeric variables are handled as '12.3' this will customize the variables to fit with the current culture
value = removeAndReplaceLast(value, '.', decimalSeperator);
}
//Add decimalseperator if string does not contain one
if (numDecimalPlaces > 0 && value.indexOf(decimalSeperator) === -1) {
value += decimalSeperator;
}
var index = value.indexOf(decimalSeperator)
var zerosToAdd = numDecimalPlaces - (value.length - index - 1);
for (var j = 0; j < zerosToAdd; j++) {
//Add zeros until numberOfDecimalPlaces is matched for uniformity in display values
value += '0';
}
if (index !== -1) {
if (numDecimalPlaces === 0) {
//Remove decimalseperator when there are no decimal places
value = value.substring(0, index)
} else {
//Cut values that have to many decimalplaces
value = value.substring(0, index + 1 + numDecimalPlaces);
}
}
if (ErrorsInTable.indexOf([row, col]) !== -1) {
RemoveCellFromErrorList(row, col);
}
} else {
AddCellToErrorList(row, col);
}
}
//console.log("r:" + row + " c:" + col + " v:" + value);
return value;
}
The inputParameter is an array, due to handsontable hooks using arrays for edit-events. parameter[2] is the old value, should this be needed at any point.
This code works reasonably fast even when copying 2k records from Excel (2s-4s).
One of my main hindrances regarding execution speed was me using the handsontable .getDataAtCell and .setDataAtCell methods to check. These don't seem to handle large tables very well ( not a critique, just an observation ). This was fixed by iterating through the data via .getData method.
Has anyone discovered a way to extend or modify the functionality of the SharePoint Datasheet view (the view used when you edit a list in Datasheet mode, the one that looks like a basic Excel worksheet)?
I need to do several things to it, if possible, but I have yet to find a decent non-hackish way to change any functionality in it.
EDIT: An example of what I wish to do is to enable cascading filtering on lookup fields - so a choice in one field limits the available choices in another. There is a method to do this in the standard view form, but the datasheet view is completely seperate.
Regards
Moo
I don't think you can modify it in any non-hackish way, but you can create a new datasheet view from scratch. You do this by creating a new ActiveX control, and exposing it as a COM object, and modifying the web.config file to make reference to the new ActiveX control.
There's an example here:
Creating a custom datasheet control.
Actually, you can do this. Here is a code snippet I stripped out of someplace where I am doing just what you asked. I tried to remove specifics.
var gridFieldOverrideExample = (function (){
function fieldView(ctx){
var val=ctx.CurrentItem[curFieldName];
var spanId=curFieldName+"span"+ctx.CurrentItem.ID;

}
return "<span id='"+spanId+"'>"+val+"</span>";
}
function handleGridField(ctx, spanID){
window.SP.SOD.executeOrDelayUntilScriptLoaded(function(){
window.SP.GanttControl.WaitForGanttCreation(function (ganttChart){
var gridColumn = null;
var editID = "EDIT_"+curFieldName+"_GRID_FIELD";
var columns = ganttChart.get_Columns();
for(var i=0;i<columns.length;i++){
if(columns[i].columnKey == curFieldName){
gridColumn = columns[i];
break;
}
}
if (gridColumn){
gridColumn.fnGetEditControlName = function(record, fieldKey){
return editID;
};
window.SP.JsGrid.PropertyType.Utils.RegisterEditControl(editID, function (ctx) {
editorInstance = new SP.JsGrid.EditControl.EditBoxEditControl(ctx, null);
editorInstance.NewValue = "";
editorInstance.SetValue = function (value) {
_cellContext = editorInstance.GetCellContext();
_cellContext.SetCurrentValue({ localized: value });
};
editorInstance.Unbind = function () {
//This happens when the grid cell loses focus - hide controls here, do cleanup, etc.
}
//Below I grabbed a reference to the original 'BindToCell' function so I can prepend to it by overwriting the event.
var origbtc = editorInstance.BindToCell;
editorInstance.BindToCell = function(cellContext){
if ((cellContext.record) &&
(cellContext.record.properties) &&
(cellContext.record.properties.ID) &&
(cellContext.record.properties.ID.dataValue)){
editorInstance.ItemID = cellContext.record.properties.ID.dataValue;
}
origbtc(cellContext);
};
//Below I grabbed a reference to the original 'OnBeginEdit' function so I can prepend to it by overwriting the event.
var origbte = editorInstance.OnBeginEdit;
editorInstance.TargetID;
editorInstance.OnBeginEdit = function (cellContext){
this.TargetID = cellContext.target.ID;
/*

Here is where you would include any custom rendering
. . .
*/
origbte(cellContext);
};
return editorInstance;
}, []);
}
});
},"spgantt.js");
}
return{
fieldView : fieldView
}
})();
(function () {
function OverrideFields(){
var overrideContext = {};

Also, there are a couple of other examples out there. Sorry, I don't have the links anymore:
