Just checking to see if there is a very simple way to make the view header fixed so that as you page down in the view in XPages, the header stays where it is. position=Fixed is not a property of xp:viewColumnHeader.
If you want to add the attribute of position to xp:viewColumnHeader you can use the attrs property to do that (works on 8.5.3). You code would look something like this:
<xp:viewColumnHeader ......>
<xp:this.attrs>
<xp:attr name="position" value="fixed"></xp:attr>
</xp:this.attrs>
</xp:viewColumnHeader>
But I don't think that alone would do the trick. Some time back I created a CSS snippet to make floating Banner, Title Bar and Place Bar in Application Layout control of Extension Library. You can get some ideas from that.
yes, it is possible, but requires some JavaScript coding.
I solved it for a customer recently using with the following code. The basic idea is to geht the width of the columns out of the first line of TDs, then apply this with to the THs ad set the THs to fixed afterwards.
You need to run this function after a partial update, too. Good luck.
var fixTableHeaders = function() {
var thead = dojo.query("thead")[0];
if (!thead) return;
thead.style.position = "static";
var THs = dojo.query('.xspDataTable th');
var firstTDs = dojo.query('.xspDataTable tr:first-child td');
var secondTDs = null;
if (firstTDs.length < 2) {
// categorized view, first line is a category with only one cell
// -> we need the second line
secondTDs = dojo.query('.xspDataTable tr:nth-child(2) td');
}
var w = 0;
for (var i = 0; i < THs.length; i++) {
w = dojo.coords(THs[i], true).w;
// console.log(i+" w="+w);
THs[i].style.width = (w)+"px";
if (firstTDs[i]) {
//if (secondTDs && secondTDs[i]) secondTDs[i].style.width = w+"px";
//else firstTDs[i].style.width = w+"px";
firstTDs[i].style.paddingTop = "3em";
}
}
thead.style.position = "fixed";
}
dojo.addOnLoad(fixTableHeaders);
I saw some jQuery code the other day that could make a Table Header fixed. Don't remember where it was but something that can help you should be out there.

I have 2 lists which are Room and Equipment.
In the Equipment list there is a lookup Field to the Room list .
I want to display all related Equipment in Room simple tabular Display Form.
How should I achieve this?
A general solution would be as follow
Check you can work with the REST API in JavaScript like below. (in this step you can just make sure the URL is returning XML data you requested)
http://portal/_api/web/lists/getByTitle('Equipments')/items/?$select=Title,ID&$filter=Room eq 'room1'
create a new custom DisplayForm with SharePoint Designer and add the following jQuery Script to read and generate the previous fetched data at the end of
<script src="/_layouts/15/CDN/Js/jquery-1.11.1.min.js" type="text/javascript" > </script>
<script type="text/javascript" >
function LoadEquipments(roomValue) {
$.ajax({
url : _spPageContextInfo.webServerRelativeUrl + "/_api/web/lists/getByTitle('Equipments')/items/" +
"?$select=Title,ID" +
"&$filter=Room eq '" + roomValue + "'",
type : "GET",
headers : {
"accept" : "application/json;odata=verbose",
},
success : function (data) {
var equipments = [];
var results = data.d.results;
for (var i = 0; i < results.length; i++) {
if (equipments.indexOf(results[i].Title) < 0)
equipments.push(results[i].Title);
}
var ullist = $('<ul/>');
for (var i = 0; i < equipments.length; i++)
$('<li/>').val(equipments[i]).html(equipments[i]).appendTo(ullist);
ullist.appendTo('#divEquipements');
$("#divEquipements ul li").css("font-size", "16px").css("color", "salmon");
},
error : function (err) {
alert(JSON.stringify(err));
}
});
}
$(document).ready(function () {
var roomVal = $("#TitleValue").text();
LoadEquipments(roomVal);
});
for previous code to work as you might guess you would better add id for new td to enclose the new requirements(for example a new tr as the last row which contains aa div with id='divEquipements' ) data and also just add id='TitleValue' to the td containing the room title (usually the first row)
OK there are a lot of possibilities for achieving this. Some possible and good looking solution can be:
Overload the click of the market value in the list(can be done using JSLink) to open a Modal dialog page where all the equipments are listed(fetched using REST query)
Overload the click of the market value in the list(can be done using JSLink) and redirect to the same page but with filters to the same view.
If the number of markets are not many, views can also be created per market(Not so good, but will reduce coding effort)
If its something else you are looking for, please let know. Hope this helps!
Is it possible to eager load a field when querying content using the ContentManager?
I'm using the ContentManager to retrieve all content items of a specific content type. The content type has a MediaLibraryPickerField on it which is creating a select n+1 issue when I iterate over the results of the query. I'd like to force this data to be loaded upfront (join on initial query). This seems straightforward for a ContentPart but I can't get it to work for a ContentField. Is this possible or is there another way to avoid the select n+1 issue with fields?
Here's what I've tried but it has not effect:
var myQuery = _contentManager.Query(new[] { "MyContentType" })
.WithQueryHints(new QueryHints().ExpandParts<MediaPart>());
I've also tried expanding the record:
var myQuery = _contentManager.Query(new[] { "MyContentType" })
.WithQueryHints(new QueryHints().ExpandRecords<MediaPartRecord>());
Here's how I fixed the problem for a projection page, but the same method, or something simpler, could be applied in your case.
In an alternate template for the Content shape of the projection page, Content-ProjectionPage.cshtml, I did the following, which creates a lookup for media that items will be able to use later:
// Pre-fetch images
var projectionItems = ((IEnumerable<dynamic>)
((IEnumerable<dynamic>)Model.Content.Items)
.First(i => i.Metadata.Type == "List").Items)
.Select(s => (ContentItem)s.ContentItem);
var mediaLibraryFields = projectionItems
.SelectMany(i => i.Parts.SelectMany(p => p.Fields.Where(f => f is MediaLibraryPickerField)))
.Cast<MediaLibraryPickerField>();
var firstMediaIds = mediaLibraryFields
.Select(f => f.Ids.FirstOrDefault())
.Where(id => id != default(int))
.Distinct()
.ToArray();
var firstMedia = WorkContext.Resolve<IContentManager>()
.GetMany<MediaPart>(firstMediaIds, VersionOptions.Published, QueryHints.Empty);
var mediaCache = Layout.MediaCache == null
? Layout.MediaCache = new Dictionary<int, MediaPart>()
: (Dictionary<int, MediaPart>) Layout.MediaCache;
foreach (var media in firstMedia) {
mediaCache.Add(media.Id, media);
}
In your case, you don't have to do the complicated drilling into shapes to dig out the fields, as you have access to them directly. I had to do that because the view or a shape table provider is unfortunately the easiest place for me to do that.
Then, when I want to display an image, all I have to do is access my lookup and try to get it from there. In my alternate template MediaLibraryPicker.Summary.cshtml, I do this:
var field = (MediaLibraryPickerField)Model.ContentField;
var imageIds = field.Ids;
if (imageIds.Any()) {
var cm = Model.ContentPart.ContentItem.ContentManager as IContentManager;
var title = cm == null || Model.ContentPart == null
? "" : cm.GetItemMetadata(Model.ContentPart).DisplayText;
var mediaCache = Layout.MediaCache as Dictionary<int, MediaPart>;
var firstImage = mediaCache != null
? mediaCache[imageIds.First()]
: cm.Get(imageIds.First()).As<MediaPart>();
<div class="gallery">
<img src="#Display.ResizeMediaUrl(Path: firstImage.MediaUrl, Width: 132)" class="main" alt="#title"/>
</div>
}
I'm only displaying the first image in the field, here, but you could change that where it does f.Ids.FirstOrDefault(). Just do f.Ids instead and replace the Select with a SelectMany. Also change the summary template so it displays all images after looking them up in the same dictionary.
Once I did that, I had no select N+1, and instead got a single SQL query for all the images on the page.
I'm using pagedown on my website right now, and it's awesome so far, the only detail is
it's not a programming-oriented website, so I'd like to remove the 'code' button.
Is there a way I can do it? I tried using CSS to hide the buttons but the html has inline styles "left: xxx" which I can't change using CSS.
Thanks in advance!
If you open up Markdown.Editor.js, and scroll to approximately line 1360 (it varies depending upon which version you're using), you'll see an area with:
group1 = makeGroup(1);
buttons.bold = makeButton("wmd-bold-button", "Bold - Ctrl+B", "icon-bold", bindCommand("doBold"), group1);
buttons.italic = makeButton("wmd-italic-button", "Italic - Ctrl+I", "icon-italic", bindCommand("doItalic"), group1);
group2 = makeGroup(2);
buttons.link = makeButton("wmd-link-button", "Link - Ctrl+L", "icon-link", bindCommand(function (chunk, postProcessing) {
return this.doLinkOrImage(chunk, postProcessing, false);
}), group2);
buttons.quote = makeButton("wmd-quote-button", "Blockquote - Ctrl+Q", "icon-blockquote", bindCommand("doBlockquote"), group2);
buttons.code = makeButton("wmd-code-button", "Code Sample - Ctrl+K", "icon-code", bindCommand("doCode"), group2);
buttons.image = makeButton("wmd-image-button", "Image - Ctrl+G", "icon-picture", bindCommand(function (chunk, postProcessing) {
return this.doLinkOrImage(chunk, postProcessing, true);
}), group2);
So on and so forth. Simply quote out the buttons you don't want.
Alternatively, you can simply leave out the entire wmd-buttons div and only use the editor and preview components.
Search for doClick(buttons.code)in the code and comment it out
If you look at the makeButton function:
var makeButton = function (id, title, XShift, textOp) {
var button = document.createElement("li");
button.className = "wmd-button";
button.style.left = xPosition + "px";
xPosition += 25;
var buttonImage = document.createElement("span");
button.id = id + postfix;
button.appendChild(buttonImage);
button.title = title;
button.XShift = XShift;
if (textOp)
button.textOp = textOp;
setupButton(button, true); // <--- LOOK HERE
buttonRow.appendChild(button);
return button;
};
The true that is being passed in the call of the setupButton function is the isEnabled flag. What I did was just created another makeButton function and put it right under the first one. The only thing that I changed was that isEnabled flag to false. Then I changed to button.code = makeButton(...) to button.code = makeButton2(...).
buttons.code = makeButton2("wmd-code-button", getString("code"), "-80px", bindCommand("doCode"));
My extension adds a context menu whenever a user selects some text on the page.
Then, using info.selectionText, I use the selected text on a function executed whenever the user selects one of the items from my context menu. (from http://code.google.com/chrome/extensions/contextMenus.html)
So far, all works ok.
Now, I got this cool request from one of the extension users, to execute that same function once per line of the selected text.
A user would select, for example, 3 lines of text, and my function would be called 3 times, once per line, with the corresponding line of text.
I haven't been able to split the info.selectionText so far, in order to recognize each line...
info.selectionText returns a single line of text, and could not find a way to split it.
Anyone knows if there's a way to do so? is there any "hidden" character to use for the split?
Thanks in advance... in case you're interested, here's the link to the extension
https://chrome.google.com/webstore/detail/aagminaekdpcfimcbhknlgjmpnnnmooo
Ok, as OnClickData's selectionText is only ever going to be text you'll never be able to do it using this approach.
What I would do then is inject a content script into each page and use something similar to the below example (as inspired by reading this SO post - get selected text's html in div)
You could still use the context menu OnClickData hook like you do now but when you receive it instead of reading selectionText you use the event notification to then trigger your context script to read the selection using x.Selector.getSelected() instead. That should give you what you want. The text stays selected in your extension after using the context menu so you should have no problem reading the selected text.
if (!window.x) {
x = {};
}
// https://stackoverflow.com/questions/5669448/get-selected-texts-html-in-div
x.Selector = {};
x.Selector.getSelected = function() {
var html = "";
if (typeof window.getSelection != "undefined") {
var sel = window.getSelection();
if (sel.rangeCount) {
var container = document.createElement("div");
for (var i = 0, len = sel.rangeCount; i < len; ++i) {
container.appendChild(sel.getRangeAt(i).cloneContents());
}
html = container.innerHTML;
}
} else if (typeof document.selection != "undefined") {
if (document.selection.type == "Text") {
html = document.selection.createRange().htmlText;
}
}
return html;
}
$(document).ready(function() {
$(document).bind("mouseup", function() {
var mytext = x.Selector.getSelected();
alert(mytext);
console.log(mytext);
});
});

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;
if (ctx.inGridMode){
handleGridField(ctx, spanId);
}
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 = {};
overrideContext.Templates = overrideContext.Templates || {};
overrideContext.Templates.Fields = {
'FieldToOverride' : {
'View': gridFieldOverrideExample.fieldView
}
};
SPClientTemplates.TemplateManager.RegisterTemplateOverrides(overrideContext);
}
ExecuteOrDelayUntilScriptLoaded(OverrideFields, 'clienttemplates.js');
})();
Also, there are a couple of other examples out there. Sorry, I don't have the links anymore:
