RadTreeView, RadComboBox and PostBack

[Marco Minerva]

Hi all!

I have created a RadComboBox with a RadTreeView, like the one in the example that is shipped with RadControls. Now I would like that the text of the ComboBox is persisted between PostBack. Is it possible?

Thanks.

Hello Marco,

You can store the text of the Selected Node as a Value of the one Item of the ComboBox. Using track/commitChanges in this case will persist the Value across postbacks. On load of the ComboBox you can restore its text from its Item's Value.

<telerik:RadComboBox ID="RadComboBox1" runat="server" Height="140px" Width="215px"
    ShowToggleImage="True" Skin="WebBlue" style="vertical-align:middle;"
    OnClientLoad="comboLoad">

                             function comboLoad(sender, eventArgs)
            {
                sender.set_text(sender.get_items().getItem(0).get_value());
            }

            function nodeClicking(sender, args)
            {
                var comboBox = $find("<%= RadComboBox1.ClientID %>");

                var node = args.get_node()

                comboBox.set_text(node.get_text());

                comboBox.trackChanges();
                comboBox.get_items().getItem(0).set_value(node.get_text());
                comboBox.commitChanges();

                comboBox.hideDropDown();
            }

I hope this helps.
