Using Telerik RadGrid view.  After reopening query in prodataset the session crashes without any error message.

procore. No error message.

The problem does not happen when the data is displayed using an Infragistics UltraGrid.  

The exact cause is not known at this time.
 

Fixed version(s): OpenEdge 12.6

Suspend notifications to the Telerik RadGrid with Begin/EndUpdate while the query is being re-opened.  

    METHOD PRIVATE VOID ReOpen(INPUT pcCharacter AS CHARACTER): 
        
             THIS-OBJECT:radGridView1:BeginUpdate().
             
             // Code to re-open the prodataset query 
             CustModel:FillDataSet(pcCharacter).
             bindingSource1:HANDLE = CustModel:GetDataSet().
             bindingSource1:Handle:TOP-NAV-QUERY:QUERY-OPEN().
             
             THIS-OBJECT:radGridView1:EndUpdate().                
    END METHOD.
