So do I. vs2010 and the latest webdatagrid.

Code:

Private Sub WebDataGrid1_RowSelectionChanged(sender As Object, e As Infragistics.Web.UI.GridControls.SelectedRowEventArgs) Handles WebDataGrid1.RowSelectionChanged

Error: NULL reference. Object reference not set to an instance of an object.

Does anyone know how to solve this issue, ie. retrieve the row details from the server side?

Also this procedure only fires when ajax=FALSE in the grid.

Regards,

Graham.

I am having the same issue.

When the Row SelectionChanged event fires on the server side, e.CurrentSelectedRows(0) (the only row I selected) comes back as Nothing.

Running webgrid version 10.3.20103.2046.

<%@ Register Assembly="Infragistics35.Web.v10.3, Version=10.3.20103.2046, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb" namespace="Infragistics.Web.UI.GridControls" tagprefix="ig" %>

Infragistics 10.3
.NET Framework 3.5
Visual Studio 2008

NOTE - Row Selection seems to be working properly in version 10.3.20103.1013.

Hi,

I have the same problem. I created a simple grid page (below). Data populated ok but I always got null value on e.CurrentSelectedRows[0]

Client Code:
