Hi Daniel,
Thank you for your interest in Syncfusion Products.
The scrollbar position can be made to the selected TreeViewNode using one of the next code snippets in your coding.
//server side
protected void Page_Load(object sender, EventArgs e)
{
TreeView1.EnsureVisibleItem();
}
//client side
Also please refer the sample below which illustrates the scrollbar position to the selected TreeViewNode.
