Find TreeView in another user control

[Joe]

Hi,
This is killing me and I know it's probably just a general .net question, but I was hoping someone here could help out...

I am dynamically loading two user controls into a page.
treeview.ascx - contains a treeview with id "rtv"
editor.ascx - contains rad editor

I'm loading the user controls like this from default.aspx.vb:
Dim ctrlPage As UserControl = LoadControl(ctrlPath & "page/treeview.ascx")
PlaceHolder0.Controls.Add(ctrlPage)

I would like to find "rtv" in treeview.ascx from the code behind of editor.ascx so that I can enurate through the nodes.

Make sense?

Thanks for any help,
Joe

Hi Joe Hakooz,

To accomplish this you should have strictly defined base page and user control classes in the App_Code folder that will be inherited by the specific user controls and the page. The class for the treeview holder user control can expose the RadTreeview reference by a property and the editor holder user control will get a reference to it by casting its Page property to the exact page type.

Having the page constructed this way is not recommended, as the controls become too tightly coupled. Would you instead consider creating a third user control that will have a reference to both the user controls and will control them?

"Would you instead consider creating a third user control that will have a reference to both the user controls and will control them?"

Absolutely...

Let's see if I have this straight. Create a new user control, which loads the other user controls. Then default.aspx would load only the new control.

But in the codebehind of the new control, how would I reference my treeview in treeview.ascx?
Dim treeview As RadTreeView = Me.FindControl("rtv")

Thanks again

Hello Joe Hakooz,

Please, find attached a sample project illustrating the 'third control' approach discussed above.

I hope this helps.
