Hi,
I want to populate huge(Parent/Childs) data in RadDropDownTree from the database. But it's taking long time to load.
What i want to do..
I want populate first Parent Data then when user click on + then populate the child data
DataTable dtData = GetList();
RadTreeNode rootTreeNode = new RadTreeNode();
foreach (DataRow row in dtData.Rows)
{
    rootTreeNode = new RadTreeNode(row["name"].ToString(), row["ID"].ToString());    
    if (Convert.ToBoolean(row["HasChilds"]))
    {                  
       // HERE I WANT TO ADD SERVERSIDE EXPAND MODE                   
    }
   RadddTreeSubFile.EmbeddedTree.Nodes.Add(rootTreeNode );
}

Hi Venkata,

Please have a look into this online demo which describes the Load On Demand feature of RadTreeView.

Thanks,
Princy.

Does RadDropDownTree supports ExpandMode at serverside?

Hello,

I would suggest accessing the embedded RadTreeView using the RadDropDownTree property EmbeddedTree. Once you have a reference to the RadTreeView you are able to set the expand mode for node or add a new node with ExpandMode server-side. Please find here more information.
