ExpandedImage is not shown if node has no childs

[Robin]

Hi,

is it possible to display the ExpandedImage of a node, even if the node has no childNodes (is empty)?

At the moment there is a plus sign in front of a node before you expand it.
If you expand a node which is NOT empty there will be a minus sign,
but if you expand a node which is empty there will be no minus sign (only the lines).

Is there any attribute to change this behaviour?

thank you!

Hello Robin,

Please take a look in to this forum which shows how to hide the expand/collapse image of the root node of tree.
Drop Expand/Collapse Image From Root Node

You can iterate through the nodes (and check for the nodes count) and hide the expand/collapse image using same logic described in forum.

Hope you can achieve the requirement easily.

[Note: In my case, it is not showing expand/collapse image for my simple treeview, if there are no child nodes]

Thanks,
Shinu.

Hello an Thank you for the quick answer,

unfortunately i want the opposite behaviour.

I want to show the collapse image of an empty node.

At the moment there is NO collapse image if the node is empty.

thank you, Robin

Hi Robin,

This scenario is not supported unless you add an invisible child node as in the code bellow:

<telerik:RadTreeView runat="server" ID="RadTreeView1">
          <Nodes>
              <telerik:RadTreeNode runat="server" Text="Root RadTreeNode1">
              </telerik:RadTreeNode>
              <telerik:RadTreeNode runat="server" Text="Root RadTreeNode2">
              </telerik:RadTreeNode>
              <telerik:RadTreeNode runat="server" Text="Root RadTreeNode3" Expanded="true">
                  <Nodes>
                      <telerik:RadTreeNode runat="server" Text="Child RadTreeNode 1" Visible="false">
                      </telerik:RadTreeNode>
                  </Nodes>
              </telerik:RadTreeNode>
          </Nodes>
      </telerik:RadTreeView>
