dynamic controls losing focus on click event

[Stuart]

I have a treeview control that is programatically populated.

I capture the click event server side, so I can expand or collapse nodes on the text click, not just the expander image.

One of the nodes has a textbox control added to it. but every time I click the text box to write into it, the node posts back and the textbox loses focus. I tried setting the clicked node's focus property but it bid not help with setting the focus of the textbox.

Any ideas?

Thanks
