Hi,

I want to have my own custom sorting algorithm in JS on a ultraWebGrid column, and also allow users directly modifing cell values.

I followed the Url below to do the Client side sorting of a particular column in the UltraWebGrid.

http://help.infragistics.com/Help/NetAdvantage/ASPNET/2010.1/CLR3.5/html/WebGrid_Defining_a_Custom_Sorting_Algorithm_Client_Side.html

I cannot get it to work until I do the following:

UltraWebGrid1_InitializeLayout() {

e.Layout.LoadOnDemand = Infragistics.WebUI.UltraWebGrid.LoadOnDemand.NotSet; // or other non-Xml options...

} 

because in the sorting Javascript (below), if the LoadOnDemand is Xml or 3, it performs sortXml(),

not my custom sorting function.

function igtbl_clctnSort(sortedCols)
{
 if(
  !this.Band.IsGrouped && this.Grid.LoadOnDemand==3)
  return this.sortXml(); ...

}

However, once I set the LoadOnDemand property to anything other than Xml, custom sorting works,

but if I edit a data cell (with column  DataType= System.String),

then I move the mouse focus to another cell, the cell value will change from the new value I entered,

back to the old value! I think it may cause a post back somehow. I can only fix this problem by setting the LoadOnDemand back to Xml.

But then I cannot do custom sorting!

Any ideas? I am using NetAdvantage_ASPNET_20092 for CLR3.5

Thanks.
