Telerik RadTree inside combo box ?

[Seabus]

Hi,

I'm trying to insert a telerik tree view inside a telerik combo box ....
I'm looking at this example:
http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/treeviewcombobox/defaultcs.aspx

The question is how do I go about having a default value for the combo box ...
In the example above how would I set "Brazil" as the default value for the combo box ?

Hello Seabus,

Try the following code snippet in the OnClientLoad event of the RadCombobox.
Javascript:

function OnClientLoad(sender)
     {
       var tree = $find('<%= RadComboBox1.Items[0].FindControl("RadTreeView1").ClientID %>');
       var node=tree.get_nodes().getNode(1);
       node.select();
       sender.set_text(node.get_text());
    }

Thanks,
Shinu.

Sadly enough this does not work since I'm loading the nodes in the tree manually on my PageLoad function , so I think what happens here is that var node=tree.get_nodes().getNode(1); gets called but there are no nodes loaded at that point.

Hello Seabus,

You can set a default selected item for the ComboBox in code-behind.
Here is an example how to do that:

protected void Page_Load(object sender, System.EventArgs e)
   {
       if (!Page.IsPostBack)
       {

           var comboBoxItems = RadComboBox1.Items;
           RadTreeView treeView = (comboBoxItems[0].FindControl("RadTreeView1") as RadTreeView);
           RadTreeNode treeNode = treeView.FindNodeByText("Brazil");
           treeNode.Expanded = true;
           treeNode.Selected = true;

           RadComboBox1.Text = treeNode.Text;
       }
   }

Best wishes,
