Hi Amit,

A possible reason for the get_masterTableView() method to return null is if you are trying to access the MasterTableView before it is created. If it is called after the GridCreated client-side event, it should always return the respective MasterTableView client object.

To resolve issue I added the sort command. 
 

protected  

void RadGrid1_SortCommand(object source, Telerik.Web.UI.GridSortCommandEventArgs e)

 

{

 

 

GridSortExpression expression = new GridSortExpression();

 

 

 

if(e.Item.OwnerTableView.SortExpressions.Count == 0 || e.Item.OwnerTableView.SortExpressions[0].FieldName != e.SortExpression)

 

{

expression.SortOrder =

GridSortOrder.Descending;

 

}

 

else if(e.Item.OwnerTableView.SortExpressions[0].SortOrder == GridSortOrder.Descending)

 

{

expression.SortOrder =

GridSortOrder.Ascending;

 

}

 

else if(e.Item.OwnerTableView.SortExpressions[0].SortOrder == GridSortOrder.Ascending)

 

{

expression.SortOrder =

GridSortOrder.None;

 

}

e.Item.OwnerTableView.SortExpressions.AddSortExpression( expression );

e.Item.OwnerTableView.Rebind();

 

BindGrid(selectedNode);//This function will done DB binding.  

}



Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: An item with the same key has already been added.
