jqGrid Filtering Records - search

It seems there have been a few questions here regarding this subject, and they have some great answers, but it seems that my case is a little different. I need to filter the records displayed in a jqGrid, but entirely client-side.
For a number of reasons, the best way for me to populate my grid is with an array that's emitted directly into the JavaScript on the page. The grid itself doesn't interact with the server at all. I have some custom AJAX happening in various grid events, but that's it. (Basically, I'm integrating this with an existing set of available services which can't change significantly.)
What I'm looking to do is filter the grid based on a simple text input and button. My page has the text input, the button, and a table (which becomes the grid on document ready). I'd like to bind to the click event of the button (normal jQuery event binding, nothing special) and use the value from the text input as a display filter on the jqGrid.
By "filter" I mean to display only the records which contain a match (in any field) for the text in the input. Then, to display all records, just empty the input and click the button again. Additionally, the grid is multi-select and the selections need to persist through filtering. I just need to be able to hide the rows which don't match what's in the input.
Is this possible?

To filter local grid you should only fill filters property of the postData parameter of jqGrid and set additionally search:true.
To save selection of the grid you can use reloadGrid with additional parameter [{page:1,current:true}] (see here).
The corresponding code can be the following
$("#search").click(function() {
var searchFiler = $("#filter").val(), grid = $("#list"), f;
if (searchFiler.length === 0) {
grid[0].p.search = false;
$.extend(grid[0].p.postData,{filters:""});
}
f = {groupOp:"OR",rules:[]};
f.rules.push({field:"name",op:"cn",data:searchFiler});
f.rules.push({field:"note",op:"cn",data:searchFiler});
grid[0].p.search = true;
$.extend(grid[0].p.postData,{filters:JSON.stringify(f)});
grid.trigger("reloadGrid",[{page:1,current:true}]);
});
I made the demo for you which filter for two columns 'Client' ('name') and 'Notes' ('note') you can extend the code to search in all columns which you need.
Depend on what you exactly mean with the saving row selection you can need to save the current selection from the selarrrow in a variable and restore the selected rows with respect of setSelection method.

Force user to select only one value from filter spotfire

Is it possible to force the user to select only one value from a filter ?
For a radio button filter as below, is it possible to remove the buttons all & none and make sure that only one Choice is selected ?
you cannot change the existing filter features or functionality without developing a custom extension for a new filter control.
that said, you can certainly emulate a filter using what's called a Property Control and a Data Limiting Expression. for single selection, you're stuck with either a Dropdown control or a Listbox (single select) control.
you would need to...
create a Text Area Visualization on the page somewhere
insert a Listbox or Dropdown Property Control into the Text Area Visualization
create a Document Property with the same data type as your filter column and associate it to the Property Control. you can set this to Unique Values in Column or write in your own Fixed values.
open the Properties dialog on the visualization you'd like to filter and navigate to the Data page
scroll down to Limit Data Using Expression and use an expression like [MyFilterColumn] = "${MyDocumentProperty}" (quotes are required for string values; if numeric then omit quotes)
Please add this CSS in the HTML page of the spotifre to remove all and none
.ColumnFilter .sf-element-filter-item:last-of-type { display:none; }
.ColumnFilter .sf-element-filter-item:first-of-type { display:none; }
Another way to force the users to select one option is to add a Show/Hide in the visualization like this: Hide if UniqueCount([Field]) is greater than 1

How to hide the sorting arrow in GXT3 grid?

Use case: User initiate the search with the a search criteria and returned result displayed in GXT3 grid. Column sorting enabled in gxt3 grid so user could sort data by selecting column header and there is arrow to indicate the sort order in grid. if the user initiate search second time, I could be able to clear the user selected column and set default sorting but still sort arrow displayed in grid. How can I hide the sorting arrow in grid? Thanks for your time.
Clear sorting info:
PagingLoadConfig.getSortInfo().clear();
Example basic grid
UPDATE:
GXT Version : 3.0.6
if (loadConfig.getSortInfo() != null && !loadConfig.getSortInfo().isEmpty()) {
loadConfig.getSortInfo().clear();
view.getDataGridWidget().getGrid().getView().refresh(true);
}
You should call refresh at grid view object after clearing the sort info of your list store. Here is the example code:
listStore.getSortInfo().clear();
grid.getView().refresh(true); // must be true, to include the grid header in refresh operation
Hope this could help you.

Getting data from a datasource with Filter by Column Value?

I have a list box where I am trying to get the datafrom the people view in names.nsf.
The first column of the people view is computed and shows Last Name , First Name.
The code below works fine for my list box values but it does not take into consideration the value in the Filter By Column Value. Basiclly the code below acts like the Filter By Column value property does not exist. I know the Filter by Column value property is working because I replaced a repeat control on the page with a computed field and the repeat control is displaying the value excepected but the list box is displaying values from the first document in the view.
Thoughts I had to fix this are:
Use getAllDocumentsByKey to just search the people view but when I do that I lose the column values and I would need to recompute the value, something that I would like to avoid if possible incase the column formula changes.
Use FTSearch but what I really need to do is search that first column only and I am not aware of search operator that searchs a column only. Is there such a thing?
Another thought would be to somehow use the values of a repeat control, as the values for my list box, but I am guessing that this is not possible. I sort of thinking something with a scope varibale but I have not worked that out yet.
A repeat control works. How can I get my code to loop through the doeuments the same way a repeat control does?
And as a side question, is there anyway to tie a pager to a datasource as oppsed to a repeat control.
BTW What I currently do is to build a list box using a few computed fields and a repeat control but what I really want to do is to use a regular xpages list box control.
Here is the code:
var doc:NotesDocument = view1.getFirstDocument();
while (doc != null && count<10)
{
var tmpDoc:NotesDocument = view1.getNextDocument(doc)
ret.push(doc.getColumnValues()[1]);
doc.recycle();
count++;
doc = tmpDoc;
}
Try to use getAllEntriesByKey. This will give You access to column values (through ColumnValue property of view entry).

How to prevent a viewPanel with category filter showing empty rows if filter is not set

I'm having this categorized view displayed in a view panel where the category column itself is not shown. Instead I'm displaying a combobox above the viewPanel where users can select from all the categories available (see screenshot below). The combo is bound to a scopeVariable and is refreshing the viewPanel onChange. The viewPanel has a computed categoryFilter reading from the same scopeVar. That all works nicely.
Now I also have implemented an additional wildcard (*) value in the selection list which (if selected) programmatically sets the cat filter to NULL. This way I'm forcing the viewPanel to show all entries. Again, this works fine, but with the drawback that now the view is showing empty rows where the category entries would be shown normally (in the screenshot you see empty rows above each entry, with 2 entries for the category "edcom GmbH" obviously belonging to the same category; those aren't separated by an empty row):
One way to at least hide those empty rows would be through means of css coding. But I would prefer those rows not being rendered at all.
Can this be done at all using a viewPanel, and how? Or do I have to use other controls like a repeat or a dataTable maybe?
Thanks in advance,
Lothar
One "hack" (an ugly one I admit) would be to change your categorization column from Firma to Firma:"--All--" or Firma:"*" and then instead of setting the category filter to NULL you set it to "--All--" (or "*").
The double category hits the indexer, but should do what you need.
Obviously there's no easy way. So meanwhile I'll stick to this css-style solution:
In the view panel und All Properties - data I set var = "entry". Then, under All Properties - styling I set a programatic value for the rowClasses property:
if(entry.isCategory()){
return "rowStyleHidden";
}
return "";
The style class "rowStyleHidden" hides those rows using
display: none;
Don't know yet how this turns out performance-wise, I'll have to observe this once I implement it in a copy of the real database.
You can also switch to a none categorized view, by having the viewname calculated based on the value in combobox.

Dynamic Layouts in Filemaker

First off I am new to FM but I have a good handle on the basics. What I need to do is this - in a contact information type layout I want to be able to alter the layout based on a specific field. Ex. When the record is brought up, the background of the layout will change colors for a client, another for vendor, etc.
I tried to change a label based on a field, with no success. My guess is that the layout is static and only the data fields change.
We use FM Pro.
Thanks,
Mark
FileMaker layouts are static, but there are still some things you can do to alter the layout based on the values of fields:
Calculation Fields
If you want the data shown in an area to change, you can use a Calculation field. A typical example of this would be a status field. To do this you would add a new field to your table and use enter a calculation on that field like:
Case (
IsEmpty(myTable::myField) ; "Please enter a value for myField." ;
myTable::myField = "wrong value" ; "Please enter a correct value for myField." ;
"Everything seems okay."
)
Conditional Formatting
To make things like background color change you can use a conditionally formatted field. I will typically add an empty numeric field (for this example we'll call it emptyField) and set it so that it can't be edited during modification.
If you place emptyField on your layout, below all the other fields and disallow the user to enter the field in either Browse or Find mode, you can then use conditional formatting to change the field's color.
Portal Hiding
You can use this technique when you want some elements of your UI to disappear when they aren't needed. For example, if you want a "submit" button to appear only when all of the records on a field are filled out.
To use this technique I will usually create a Calculated number field, called ReadyForSubmit, on the original table and give it a logical calculation like:
not IsEmpty(field1) and ... and not IsEmpty(fieldN)
(Note that the value of the above function would be 1 or 0)
I will then create a new Support table in my database and add to it a field One with a calculated value set to 1.
I will then make a relationship between myTable::readyForSubmit and Support::One.
On the layout, create a portal with one row. Put your Submit button in that layout. Now, when readyForSubmit calculates to 1 the button will appear. When it calculates to 0 the button will be hidden.
Hidden Tab Browser
Finally, you can use a tab browser where you set the title font size to 1 point, hide the border, and control the browser programmatically. You can use this for having different field arrangements for different types of records. To do this you would first give an Object name to each tab of the tab browser, say Tab1, Tab2, Tab3.
Then you would add a script, goToTab, with the logic for when you want to go to each tab. Say:
If (myTable::myField = "corn")
Go to Object (Tab1)
Else If (myTable::myField = "squash")
Go To Object (Tab2)
End If
You would then use Script Triggers to run goToTab when On Record Load.
With the release of filemaker 13 there may be another way to do this. You could use a slide control, name the panels in the control, and conditionally switch to the correct panel based on the record type.
you would drop the appropriate fields for the record type in each panel.
