Get parentItem on childRadGrid's need datasource event

[Prava kafle]

Hi,

I want  an ID of parent Table and the datakey value of recently expanded column on child grid's need data source event.  My code returns null value for currentGrid.NamingContainer .

  void childRadGrid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
        {
            try
            {
                RadGrid currentGrid = sender as RadGrid;
                
        GridDataItem  parentItem =  (currentGrid.NamingContainer as  GridNestedViewItem ).ParentItem as GridDataItem;
..
..
..
}

Any idea?
Thanks
Prava

Hello Prava,

Try the following code snippet.
C#:

protected void RadGrid2_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
  RadGrid innergrid=(RadGrid)sender;
  GridNestedViewItem nesteditem = (GridNestedViewItem)innergrid.NamingContainer;
  string dataKeyValue = Convert.ToString(((GridDataItem)(nesteditem.ParentItem)).GetDataKeyValue("ID"));
}
