Get hierarchy level and child item count

[Tina]

How can we determine the hierarchy level and child item count in a treelist?

Hi,

Try the following code.
C#:

protected void RadTreeList1_ItemDataBound(object sender, Telerik.Web.UI.TreeListItemDataBoundEventArgs e)
{
   TreeListDataItem item = e.Item as TreeListDataItem;
   int level = item.HierarchyIndex.NestedLevel;
}

protected void RadTreeList1_PreRender(object sender, EventArgs e)
{
   foreach (TreeListDataItem item in RadTreeList1.Items)
   {
      if (item.Expanded)
      {
          int count=item.ChildItems.Count;
      }
   }
}

Thanks,
Shinu

Hi,

C#:

protected void RadButton1_Click(object sender, EventArgs e)
{
     RadTreeList tree = (this.FindControl("RadTreeList1") as RadTreeList);
    TreeListEditableItem item = (TreeListEditableItem)RadTreeList1.GetItems(TreeListItemType.EditItem)[0];
    item.FireCommandEvent("Update", "");
}

Thanks,
