Here are two images, which might clearly explain the problem I'm having.

.... and here's the code for the ig-grid used to create this example...

I hope you can help.

You do have an example on the following page, which does the same kind of thing, but I'm attempting to set the data source in HTML, rather than via JavaScript.

I hope you can help.

Any word here from Infragistics?  Looking for your response to the recent posts. 

Thanks!

... oh, and part 2 of my question...

Actually, this "ListOfPrograms" array will be a JSON array populated by a web service  (so its data won't be available when the page first loads).

How do I tell the ig-grid that this drop down list's "data-source" has changed.... or does this data-source only "kick in" when the user edits a row, and the ig-grid evaluates what this ListOfPrograms contains at that point ?

I assume this is going to take more than a 

$("#iggrid1").igGrid('dataBind');

...?

Hi Martin,

Thank you for your reply, it was really useful in nudging me forward in this process.

I'm now stuck at one further issue, which I need to get around to complete my evaluation of populaiting a ig-grid, and sending edits back to a web service.

When editing a row, I would like some of the cells to have drop down lists of possible values.   And I can't do it.

I have tried having both a JavaScript variable containing hard-coded data, I have tried with an Angular variable (I was being optimistic) but neither seem to populate the drop down lists.

Actually, I want to do exactly the same as this example:
http://ko.infragistics.com/samples/aspnet/data-grid/dropdown-editors

I'm not using MVC, I'm trying my best to make this Angular-friendly... but just can't get it to work.

So, stripping it down to basics, here's my JavaScript hardcoded variable:

var ListOfPrograms = [ { "ProgramID": 1, "ProgramName": "First Program" }, { "ProgramID": 0, "ProgramName": "Second Program" }];

... and here's the <features> part of my ig-grid.   Note that a drop down list DOES appear for my ProgramName column when I edit a row... but it's  populated with "No results", so I must have the column-setting stuff badly setup  (but, once again, working examples are scarce..)

<features>
<feature name="Updating" enable-add-row="true" event-edit-row-ended="OnEditRowEnded">
<column-settings>
<column-setting column-key="GuideID" read-only="true">
</column-setting>
<column-setting column-key="ProgramName" editor-type="combo" mode="dropdown" data-source="ListOfPrograms" text-key="ProgramName" value-key="ProgramID">
    <editor-options>
    <editor-option data-source="ListOfPrograms" text-key="ProgramName" value-key="ProgramID"></editor-option>
  </editor-options>
</column-setting>
</column-settings>
</feature>
<feature name="Selection" mode="row" event-active-row-changed="OnIggridRowChanged">
</feature>
</features>

(As you can see, I've tried sticking the "data-source" stuff into both the column-setting and editor-options tags, but neither works.  I've left them in this sample to show what hopesless attempts I've tried.)

 I just can't work out how to convert this example:

name: 'Updating', columnSettings: [{ //The combo is defined as an editor provider. Combo options are defined under 'editorOptions'. columnKey: "CategoryID", editorType: 'combo', required: true, editorOptions: { mode: "dropdown", dataSource: northWindCategoriesJSON, textKey: "Name", valueKey: "ID" } }],

..taken from this page...

... into a <column-settings> attribute, as I'm trying to use.

What have I missed...?
