TreeView control events restricted by other controls.

 I'm currently having a problem using a treeview control inside an update panel. I one update panels (containing the treeview) that is conditional update with triggers bound to a couple buttons. Those buttons are part of a second update panel which also contains a few labels, couple textboxes, and a dropdown list. That update panel updates conditionally when a node in the tree view is selected. When I select a node I populate the labels, text boxes, and select one of the values in the drop-down list. The problem is that if there's anything in the drop-down list or text-boxes it acts as a sort of validation on what I can select in the tree view. So I select one node, it populates, and then I can't select any other until I clear the textbox. It doesn't even fire the event.

 If you need to see the code please let me know. I'm still kind of new to web-development so it's rather ugly looking.

 amair,

Yes, please.  Post your code.  There is something odd about the way you described setting up your trigger (which may just be me reading it incorrectly).

I actually learned some very important things kind of randomly that allowed me to finally solve this problem.

First: using a break tag in a normal text box will make it unhappy.

Second: when I was telling the drop down list which item to select I was telling the item it was selected but not telling the control to select it, which turned out to be my mistake.

Lastly: (though I learned this before posting) ASP/Ajax doesn't like putting web controls in a Genereic List.

Now why those first two things were working as some sort of odd selection control I still don't know. but now I why it wasn't working.

Custom controls having Ajax Controls
I have a custom control called ModalUpdateProgress. I don't want to narrow down the topic to why do I have to build it or something else. The point of control is to lock a sceen while postback happens so it is a conjunction of Update Progress and Modal Popup Extender. I had no problem to build a control similar to Update Progress. Then I add Modal Popup Extender:   if(typeof(undefined) != typeof(AjaxControlToolkit)) if(typeof(undefined) != typeof(AjaxControlToolkit.ModalPopupBehavior)) { this._modalPopupBehavior = $create(AjaxControlToolkit.ModalPopup...

Controlling Size of a TreeView Control
Hi guys,I have placed a Treeview control inside a table cel (into a master page). The toc itself is rather large, so the table cel adapts itself to the size of the Treeview control. But at this point it hides itself about 2 cm underneath my top banner, so the first few items in the toc cannot be entered. Is there a way to give the Treeview control a fixed size, so it starts using scrollbars if the toc becomes larger while expanding?Thx in advance,SubZero...

Custom Control within a Control Control
I am developing a custom controls that will render headers for different web sites. Within these controls, I want to place another custom control that will change the language. I created the language control and had it implement IPostBackDataHandler. This control works fine if I drag it on a new web form, but if I tell a header custom control to render it problems occur. The Language Selector custom control does not have a Page member anymore and the event handlers do not work. Does anyone have any experience with doing something similiar? Anyone have any suggestions? Thanks, ...
