[Solved] Dynamically controlling RadGrid Hierarchy

[DC]

Hi,
I have a Hierarchial RadGrid. My page is "role driven" which means, I need to show hierarchy for one role and not for others. How can I control it from codebehind.

Hello,

I suggest that you hide the detail tables of the RadGrid depending on the role of the user in the following way:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
    if (!User.IsInRole("admin"))
    {
        HideDetailTablesRecursive(RadGrid1.MasterTableView);
    }

}
public void HideDetailTablesRecursive(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;
                nestedViewItem.Visible = false;
            }
            if (nestedView.HasDetailTables)
            {
                HideDetailTablesRecursive(nestedView);
            }
        }
    }
}

I am also attaching a sample project showing how the hiding of the detail tables works.

I hope this helps.

All the best,
