Getting selected treeview data in combobox

[Adrian]

Hi

I've followed the example on putting a radtreeview in a radcombo box. My datasource for the treeview is from an entitydatasource. The Treeview DataTextField is set to "name" and the DataValueField is set to "ID" of the tree item data.

Im having a problem getting the selected ID of the selected treenode within the combo box.

When i get the .SelectedValue of the combobox it returns the DataTextField of the treeview.
When i get the .SelectedItem.Value of the combobox it returns the DataTextField of the treeview.
When i get the .SelectedItem.Text of the combobox it returns an empty string.

Is this a problem at my end or a bug

Thanks

Hello Adrian,

You can access the Selected TreeNode value as shown in the code below. You have to access the TreeView and then get its SelectedValue.
c#:

 protected void RadComboBox1_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
    {
        RadComboBox combo = (RadComboBox)o;
        RadTreeView treeView = (RadTreeView)combo.Controls[0].Controls[1];
        string strtxt = treeView.SelectedValue;
    }

Thanks
Princy.
