Hi there,

I'm having a usability issue in TreeViewAdv. Everytime a name of an item is longer then the treeview width, a tooltip is shown with the name of the item. Unfortunately, the user can't drag the item anymore (see attachment).
Can I prevent the tree from showing this tooltip or can I move the tooltip, so that the user can drag the item?

Hi Thorsten,

Thank you for your interest in Syncfusion Products.

I am afraid that I was not able to reproduce the issue.However, you could show the tooltip below the current highlighted item, by disabling the tooltips and by assigning HelpText for all the TreeNodeAdv .

1.Disabling Tooltips:

You could disable the tooltips for the TreeNodeAdv using the BeforePopup event handler associated with the TreeViewAdv:

this.treeViewAdv1.ToolTipControl.BeforePopup += new CancelEventHandler (Tooltip_BeforePopup);
private void Tooltip_BeforePopup (object sender, CancelEventArgs args)
args.Cancel = true;


You can also use HelpText instead of tooltip for the node with longText.It will be displayed below the current highlighted item:

treeNodeAdv1.HelpText = "Node0";

Please let me know if any concerns.
