When I set the RadDropDownTree Enbaled as False, the Clear button still working and clear the Selected value.

Validation is not working as expected in Dropdowntree. In the demo page http://demos.telerik.com/aspnet-ajax/dropdowntree/examples/validation/defaultcs.aspx, if any one node is checked, the validation message "You need to select a type or a category before submitting the page" is displayed. If multiple checkboxes are checked, the message is not displayed. I do not want the validation message displayed when  check box is  checked.

In order to workaround this bug, you can handle the OnClientNodeClicking client-side event of the embeddedTree and cancel the propagation of the event if the node that is about to be selected is disabled:

 protected void Page_Load(object sender, EventArgs e)
 {
        Reporting.EmbeddedTree.OnClientNodeClicking = "OnClientNodeClicking";
 }

<script type="text/javascript">
            function OnClientNodeClicking(sender, args) {
                var nodeToSelect = args.get_node();

                if (!nodeToSelect.get_enabled())
                    args.set_cancel(true);
            }
        </script>

Two requests.

1. When filtering allow tree children to be unhidden if the parent matches the pattern. Maybe add filter by level (parent, child, both).

2. Add highlight capability to show all matching node filter patterns.

Cannot add a label to a RadDropDownTree

When the RadDropDownTree contains a lot of checked items, The tooltip of the control shows all items delimited with a semicolon. For large lists it is useless (especially if the page has RadToolTip which shows a huge tooltip on screen blocking the UI). Please add an option on the control properties to disable the control from updating it's tooltip (title attribute) when items are checked

Hello,

 

I'm unsure whether this is an actual bug, but I can't seem to clear the selected text in the RadDropDownTree when i use UncheckAllNodes or UnselectAllNodes from the server side.

I try to to set SelectedText and SelectedValue on the RadDropDownTree control to string.Empty but neither works.

The nodes are unchecked though, but the text showing the previous selection is still visible after i  reload the page.

What should I do to also set the text to represent the selection done by UncheckAllNodes?

 

Kind regards,

Anders
