I need to hide expand image based on condition.

[Joby]

Hi,
I need to make hierarchical grid based on some condition.This means if there is no details,then there should not be (+) image in the grid.I need to hide expand image based on condition.Each master row i have the status of whether detail is there or not.

Hello Joby,

Try the following code in PreRender event to hide ExpandCollapseColumn when there are no child records.
C#:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
    HideExpandColumnRecursive(RadGrid1.MasterTableView);
}
public void HideExpandColumnRecursive(GridTableView tableView)
{
    GridItem[] nestedViewItems = tableView.GetItems(GridItemType.NestedView);
    foreach (GridNestedViewItem nestedViewItem in nestedViewItems)
    {
      foreach (GridTableView nestedView in nestedViewItem.NestedTableViews)
      {
        if (nestedView.Items.Count == 0)
        {
          TableCell cell = nestedView.ParentItem["ExpandColumn"];
          cell.Controls[0].Visible = false;
          cell.Text = " ";
          nestedViewItem.Visible = false;
        }
       if (nestedView.HasDetailTables)
       {
        HideExpandColumnRecursive(nestedView);
        }
      }
   }
}

Thanks,
Princy.

Hi Princy,
Thank for the reply.when i am using this code,this will remove all (+)images.But i don't want this.I need to remove (+) based on some condition.

Hi Joby,

I guess you are using HierarchyLoadMode="ServerOnDemand".If so the DataBind of a child GridTableView would only take place when an item is Expanded. So initially the count of child will be null and it will hide Expandcollapse image for all Grid rows.
