Grid Not Displaying

[John]

On page load the radgrid is displaying but after postback it is gone.  The grid on page load looks like:

  <div id="RadGrid1" class="RadGrid RadGrid_Default">
 
<!-- 2010.2.929.20 --><table cellspacing="0" class="rgMasterTable" border="0" id="RadGrid1_ctl00" style="width:100%;table-layout:auto;empty-cells:show;">
 <colgroup>

After postback it looks like:

  <div id="RadGrid1" class="RadGrid RadGrid_Default">
 
<!-- 2010.2.929.20 --><input id="RadGrid1_ClientState" name="RadGrid1_ClientState" type="hidden" />
 </div>

Any thoughts.

Thanks

John

Hello John,

The reason for the behavior which you described is that the control is not properly bound to data. Most probably you are calling DataBind() method which will break the default functionalities of the control, such as filtering/sorting/paging. To populate the control with data, you need to use only NeedDataSource. Whenever you need to raise the NeedDataSource event handler again, you can call the .Rebind() method of the control. This would raise the NeedDataSource event handler, allowing you to pass the proper data to populate the control.

I hope this information helps.

Sincerely yours,
