[Solved] Changing checkbox state when user clicks on the node label

[Lou]

How do I change a node's checkbox state when the user clicks on the node's label text as opposed to clicking on the checkbox itself? 

This needs to work when the treeview is in Tri-state mode (needs to handle intedeterminate state as well as on/off). 

Thanks

Hi Lou,

Thank you for writing.

The following example shows how you can achieve this:

public RadForm1()
{
    InitializeComponent();
    radTreeView1.Click += RadTreeView1_Click;
    radTreeView1.NodeFormatting += RadTreeView1_NodeFormatting;
}

private void RadTreeView1_NodeFormatting(object sender, Telerik.WinControls.UI.TreeNodeFormattingEventArgs e)
{
    e.NodeElement.ContentElement.ShouldHandleMouseInput = true;

}

private void RadTreeView1_Click(object sender, EventArgs e)
{
    var element = radTreeView1.ElementTree.GetElementAtPoint(((MouseEventArgs)e).Location);
    if (element is TreeNodeContentElement)
    {
        var node = element.Parent as TreeNodeElement;
        node.Data.Checked = !node.Data.Checked;
    }
}

I hope this information is useful. Let me know if you need further assistance.
