Hi, 

I need a specific column in my tree to be a drop down list. I can see the drop down arrow but when I click on it nothing happen. How can I have a simple drop down for a specific column?

Included is a screenshot.

Thanks!!!

    Infragistics.Win.AppStyling.StyleManager.Load(@"C:\Users\Public\Documents\Infragistics\NetAdvantage 2011.2\Windows Forms\Samples\Data\StyleLibrary\IG.isl");
    this.batchTreeControl.ViewStyle = Infragistics.Win.UltraWinTree.ViewStyle.FreeForm;

    this.batchTreeControl.ViewStyle = Infragistics.Win.UltraWinTree.ViewStyle.FreeForm;
    batchTreeControl.Override.UseEditor = DefaultableBoolean.True;

    UltraTreeNode batches = this.batchTreeControl.Nodes.Add("batches", "Batches");

    UltraTreeNode mybatchNode = batches.Nodes.Add("mybatch", "My Batch");

    UltraTreeColumnSet columnSet = new UltraTreeColumnSet();

    mybatchNode.Override.ColumnSet = columnSet;

    columnSet.Columns.Add("Name");

    columnSet.Columns.Add("Attribute");

    columnSet.Columns["Attribute"].DataType = typeof(String);
    columnSet.Columns["Attribute"].AllowCellEdit = AllowCellEdit.Full;

    ValueList valueAttributes = new ValueList();
    valueAttributes.ValueListItems.Add("Batch", "Batch");
    valueAttributes.ValueListItems.Add("Plate ID", "Plate ID");
    valueAttributes.ValueListItems.Add("Job Code", "Job Code");

    columnSet.Columns["Attribute"].ValueList = valueAttributes;

    mybatchNode.Cells["Name"].Value = "My Batch";
    mybatchNode.Cells["Attribute"].Value = "Batch";

}
