Hi,

I have ultragrid and its layout is being defined in InitializeLayout event. (Visible columns/Column Width/ColumnOrder etc.). Its datasource is set to Datatable. I have a refresh button which causes Datatable to reloaded and is bind to grid. The operations I can perform on grid at runtime: 1) Hide/Unhide columns using ColumnChooser. 2) Change Column width. 3) Change columns order. So after doing above operations and then clicking Refresh button, grid's source is refreshed and thus above changes to Grid UI are lost as grid's InitializeLayout is called. Can anyone help me in this regard ?

Probable solution I will be implementing: Maintaining Grid's layout in the form of xml in cache, and whenever there is change in Grid's property,(PropertyChange Event) will update that xml object. And thus if datasource is changed, grid's layout will be set from xml object in InitializeLayout event.

The problem with above solution is that PropertyChange event fires many times. So updating xml cache object will affect performance.

Please suggest any alternative solution.

Regards,

Karan
