Trouble with setting properties UltrTreeNode.Visible
posted

I have trouble with setting properties UltrTreeNode.Visible. Throws System.ArgumentOutOfRangeException. Code below.

Help me please :(

private void ApplyFilter()
{
    Action<TreeNodesCollection> applyFilter = null;

    applyFilter = coll =>
   {
       foreach (var node in coll)
      {
         var flg = Filter(node);
         if (node.Visible != flg)
         {
             node.Visible = flg; // on this line the exception occurs on the last node
         }
         else
        {
            applyFilter(node.Nodes);
        }
   }
};

    applyFilter(checkTreeControl.ultraCheckTree.Nodes);
}

private bool Filter(UltraTreeNode node)
{
     var chk = checkOnlyDependent.Checked;
     return (!chk) || (chk && HasCheckedItems(node.Tag as TItem));
}

    Hi Andrey,

    Are you up to date on the latest version of our controls for Windows Forms? eg. 2015.1

    A call stack and a sample of the behavior would also be very helpful to us. Let me know if you have any additional questions.
