I am trying to find the selected node in a TreeView on the client side.
I have tried the code in this example which is linked to in a similar thread listed here.
I am not able to figure out what I am doing wrong. When calling GetSelectedNodes() I contiune to get the error message "Object does not support this property or method". I have tried setting MultiSelect = true and false with the same error.
Here is a sample of my code.
| <body> |
| <script type="text/javascript"> |
| function getSelectedNodes() |
| { |
| var tree = <%= RadTreeView1.ClientID %>; |
| var nodes = tree.GetSelectedNodes(); |
| alert(nodes.length); |
| } |
| </script> |
| <form id="form1" runat="server"> |
| <asp:ScriptManager ID="ScriptManager1" runat="server"> |
| </asp:ScriptManager> |
| <telerik:RadTreeView ID="RadTreeView1" runat="server"> |
| <Nodes> |
| <telerik:RadTreeNode runat="server" Expanded="True" Text="1" Value="1" /> |
| </Nodes> |
| </telerik:RadTreeView> |
| <input id="Button1" type="button" value="Get Selected Node" onclick="getSelectedNodes();" /> |
| </form> |
| </body> |
