Hi EO, I think I'm missing something with the TreeView control. No matter what I try, I keep getting nothing returned when I lookup what checkboxes are checked. Here's some code.
Code: HTML/ASPX
<eo:TreeView ID="eoTvEstablishments" runat="server" ControlSkinID="None" Width="500px">
This is on the pages submit button
Code: Visual Basic.NET
For Each eoNode As EO.Web.TreeNode In eoTvEstablishments.SelectedNodes
Response.Write(eoNode.Text & ": " & eoNode.Value & "<br />")
Next

Hi,
You may want to use a Label control, then set the Label control's Text property instead of using Response.Write. You can also set a breakpoint in your debugger to see if that got hit.
Thanks!

No change. I don't understand it.
Am I using the correct code?

Hi,
Please create a test page that reproduces the problem. The code you posted is fine, so the problem is somewhere else. If you can create a reproducing page, we will be happy to take a look. Make sure the page runs independently.
Thanks!

Hi,
We looked into the code that you sent to us. It appears that you misunderstood what SelectedNodes is. SelectedNodes contains all selected, not checked nodes. A selected node is a node that currently is highlighted in blue, it's not related to check state of each node in any way. In order to get a list of all checked node, you will need to walk through all node recursively and check the node's Checked state.
Thanks!
