TriState-Status

[FLIDEV]

Hello,

I have an treeview with chekcboxes and tristatecheckboxes ist true. Is it possible to get the intermediate state of an parent node? The node is in the CheckedNodes-collection, but I can't find any property to differ the state.

I hope, anybody can help me.

Detlef!

Hello,

You could use the CheckState property of RadTreeNode in order to check chckbox state.

C#:

protected void RadTreeView1_NodeCheck(object sender, Telerik.Web.UI.RadTreeNodeEventArgs e)
{
    RadTreeNode node = (RadTreeNode)e.Node;
    if( node.ParentNode.CheckState == TreeNodeCheckState.Indeterminate)
    {
        Response.Write("Intermediate"); // Intermediate state
    }
}
