Hi there, The TreeView[^] control does not have the property. However, the control supports populating the node with the client side script without posting the page back, so IMHO you might want to use it. If it does not fit your demand, then could you tell why you need to this property?

So. Sometimes I have to fill my Tree with a lot of nodes and leaves. So I receive html with size about 1.5-2 Mb. It's too large. I looked at html-code and found out, that there is a lot of unnecessary code, related with doPostBack javascript. Can you tell me how can I use client side script to solve the problem? :-O -- Digitally yours, Bounz

Do you mean you want to use client side script to get rid of unnecessary code like "doPostBack"? IMO, javascript cannot help you here because this unnecessary code is emitted in the Render method of the TreeNode class by default. In this case, you might want to customize the TreeView control so that when it renders, the Text of the TreeNode, not that whole script, is rendered in the RenderContents method of the TreeView.
