Ive searched a lot looking for an answer for the problem but i havent found it

I want my asp TreeView to expand or collapse when clicking on the icon of each node, I ve seen a lot of expanding or collapsing when double clicking on the node, but i want it when clicking on the node image ONLY

The problem comes because we have a requirement which is not allowed to have the +/- buttons.

Hi,

you can use the NodeMouseClick Event and simply check if node is expanded or not.

C#

if (e.Node.IsExpanded)
                e.Node.Collapse();
            else if (e.Node.Nodes.Count > 0)
                e.Node.Expand();

With best Regards
