[Solved] Number of child nodes

[Sonia]

I need to get the number of child nodes of a treelist node.
But the instruction item.ChildItems.Count is always zero.
What I am doing wrong.



    protected void RadTreeList1_ItemDataBound(object sender, TreeListItemDataBoundEventArgs e)

    {

        if (e.Item is TreeListDataItem)

        {

            TreeListDataItem item = e.Item as TreeListDataItem;

 

            int numberOfChilds = item.ChildItems.Count;

 

 

....

Hi,

Try the following code.
c#:

protected void TreeList1_PreRender(object sender, EventArgs e)
{
   foreach (TreeListDataItem item in TreeList1.Items)
   {
      if (item.Expanded)
      {
          int count=item.ChildItems.Count;
      }
   }
}

Thanks,
Shinu

Thank you Shinu. It works ok. But is there any possibility to know the number of child items if the node is not expanded?

Hi,

As far as I know, since expand / collapse operation requires postback the child items are not created if the parent is not expanded. Hope this helps.

Thanks,
