The code below returns an 'Object reference not set to an instance of an object' error if the TopicData value is no longer an option on the rg radio button list.

I'm not sure how to handle this exception - try/catch does not seem to work.

can someone help?

Thanks.


drFound = topicDetailsTable.Rows.Find(row.Row("ID"))

 If Not (drFound Is Nothing) Then

    rg.Items.FindByValue(drFound("TopicData")).Selected = True

 End If

Attached.

Still get server error with this in place.
drFound = topicDetailsTable.Rows.Find(row.Row("ID"))

If Not (drFound Is Nothing) Then

    Try

        rg.Items.FindByValue(drFound("TopicData")).Selected = True

    Catch ex As System.Web.Services.Protocols.SoapException

        CrmServiceUtility.LogError(IO.Path.GetFileName(Request.PhysicalPath) + " | " + System.Reflection.MethodBase.GetCurrentMethod().Name, ex)

    End Try

End If

Try this way
Try
drFound = topicDetailsTable.Rows.Find(row.Row("ID"))
If Not (drFound Is Nothing) Then
        rg.Items.FindByValue(drFound("TopicData")).Selected = True
End If
Catch ex As System.Web.Services.Protocols.SoapException       
	'Your Handling Code
End Try

This is telling you that TopicData does not exist in the dsFround row.

Your catch is only catching SoapExceptions

You need to add a catch for other exceptions.
Try

drFound = topicDetailsTable.Rows.Find(row.Row("ID"))

If Not (drFound Is Nothing) Then

        rg.Items.FindByValue(drFound("TopicData")).Selected = True

End If

Catch ex As System.Web.Services.Protocols.SoapException       

	'Your Handling Code

Catch exGeneral As Exception

 'Your handling code

End Try
