Scroll a treeview so the selected node is shown

Question

I am setting the selected node of a large tree view programmatically in a partial postback. I'm also making sure the node is expanded so it's visible. Now I want to have the tree scroll so the node is in view. How can I accomplish this?

Thanks, Adam

Hi Adam, Thanks for contacting Syncfusion forums. We suggest you to use “(element).scrollIntoView(false)” in script to resolve this issue. please refer the below code snippet to achieve this,



[Script]

(Selected_element).scrollIntoView(false);

We use VS 2008 so I can't open the solution. There are no .aspx files in there either. Could you provide a 2008 asp.net web application solution that implements the scroll into view feature?
