TreeGrid

[John Burgin]

Hi,

Firstly, I'd like to say these new controls look great and thank you for supporting LightSwitch.

I'm trying to figure out how to get a tree grid to show, but can't find an easy way from the screen designer.  I've also tried putting on a normal grid, then changing the generated javascipt from ejGrid to ejTreeGrid and defining the parent as per documentation for the pure javascript control.  The grid still renders, but the parent field is returned as an "object" and there is no tree structure.

The table I'm testing it with is self referential e.g.

Tasks
ID, Name, Status, ParentTask.

where ParentTask relates to back to the task table.

Thanks,
John

Is there a way to initiate a refresh of the tree grid after a save ? 

[Mahalakshmi Karthikeyan]

Hi John,

We would like to let you know that we can refresh the TreeGrid Control after saved or modified the content using refresh() public method in Treegrid. Please find the following code snippet for details.

<input type="button" id="refresh" value="refresh" />

<script type="text/javascript">

$("#TreeGridContainer").ejTreeGrid({

//…

});

$("#refresh").click(function(){

treegridObj = $("#TreeGridContainer").data("ejTreeGrid");

treegridObj.refresh();

});

</script>

We have also prepared a sample based on this and please find the sample location below.

Please let us know if you need more information on this.
