Hide Header of DetailsTable in Hierarchy RadGrid

[Surander]

Hi All,
  I have Three level Hierarchy RadGrid.
  I have to display the grid  all records(master or details table) expended mode.
  And its working fine by enabling property of master & detailTables HierarchyDefaultExpanded="true"
  But problem is i want to hide the "Header of detailsTables" if there is no child records in any level.

Any Suggestion?

Thanks,
Surander

Hello Surander,

Try the following code snippet to hide the header when there is no record in detail grid.

C#:

protected void RadGrid1_PreRender(object sender, EventArgs e)
   {
       foreach (GridDataItem item in RadGrid1.Items)
       {
           if (item.Expanded)
           {
               GridTableView tableView = (GridTableView)item.ChildItem.NestedTableViews[0];
               if (tableView.Items.Count == 0)
               {
                   tableView.ShowHeader = false;
               }
               foreach (GridDataItem childitem in tableView.Items)
               {
                   if (childitem.Expanded)
                   {
                       GridTableView childtableView = (GridTableView)childitem.ChildItem.NestedTableViews[0];
                       if (childtableView.Items.Count == 0)
                       {
                           childtableView.ShowHeader = false;
                       }
                   }
               }
           }
       }
     }

Thanks,
Princy.

Hi Princy,
Thanks for you help but its not working for me. I am getting error:

Object reference not set to an instance of an object.

on line
GridTableView tableView = (GridTableView)item.ChildItem.NestedTableViews[0];
And line
GridTableView childtableView = (GridTableView)childitem.ChildItem.NestedTableViews[0];

Hi,
I got it by setting property of DetailTables -> GridTableView ShowHeadersWhenNoRecords="false".

Thanks

How to hide header on specific column in Radgrid in javascript?
I don't want to use table.hideColumn(column.get_element().cellIndex);

 function PrintRadGrid() {
                var radGrid = $find('<%= RadGrid1.ClientID %>');
                var table = radGrid.get_masterTableView();
                var column = table.getColumnByUniqueName("CkboxDelKey");
                
                var masterTable = $find("<%=RadGrid1.ClientID%>").get_masterTableView();
                for (var row = 0; row < masterTable.get_dataItems().length; row++) {
                    var str = masterTable.getCellByColumnUniqueName(masterTable.get_dataItems()[row], "CkboxDelKey").innerHTML;
                    if (str.indexOf("<nobr>") != -1) {
                        masterTable.getCellByColumnUniqueName(masterTable.get_dataItems()[row], "CkboxDelKey").style.display = 'none';
                    }
                }

//hide header code
//Code here

}
