I have bound a dataset to webdatatree at runtime and also have checkboxes visible and set to Bistate. First of all when I check a checkbox the CheckBoxSelectionChanged does not fire until after a postback. Secondly, after I select several checkboxes in the tree I press a button that causes a postback to run a report. In the button vb.net code I want to get the WebDataTree1.CheckedNodes.Count, but it is always 0 because the postback happens before this code is processed and the webdatatree checked boxes are not checked anymore. How do I get the checked nodes before the postback and/or keep the nodes checked after the postback?
No need to reply, I figured it out.
jcom, or anyone from Infragistics, could you explain what you had to do to get the checked nodes? I'm using load on demand so in the Page_Load event i set the datasource. I check a few nodes and I have a "Select" button that triggers a postback. In that select click event handler I want to get the checked nodes from the tree but the tree.CheckedNodes is ALWAYS empty.This seems pretty simple but I can't figure it out. What am I missing? Can someone help please?
trav,
I actually do not use the checkboxes anymore in my project but not because I did not get it to work but from what I noted I used this...
Dim
node As Infragistics.Web.UI.NavigationControls.DataTreeNode
Next
I think this is all you need to do.
