Setting the ValueList property acheived my goal to have a dropdown box within the column set!

Many thanks!

Hi,

I'm not sure what you mean by this. You could, in theory, set the DataType of a column to ComboEditor. But that doesn't really seem to make much sense or be particularly useful.

Having a Column whose DataType is ComboEditor will not display the column with a dropdown. It will just mean that the values of the cells in that column are storing ComboEditors.

If you want a dropdown list to show up in a column, you would typically do this on a column with some numeric type and use either the ValueList or the Editor/EditorComponent property on the column to provide a dropdown list.

Does this mean that we can add a ComboEditor as a valid data type in the ColumnSet?

What I want is for my tree to look like is:

-Parent 0

    - Child 0

          bool     string      float    ComboEditor

Is this possible? I've been having a difficult time implementing it

Thanks for the sample code Mike.

I did get the sequence of steps that need to be done to form the tree.
I was missing a step in between.
The way we were adding the columnSets to the parent node was different.

Thank You once again.

 Here's a little sample code I whipped up to demonstrate how to set up a tree like this: 

            this.ultraTree1.ViewStyle = ViewStyle.FreeForm;
            UltraTreeNode parentNode1 = this.ultraTree1.Nodes.Add("Parent 1");
            UltraTreeNode parentNode2 = this.ultraTree1.Nodes.Add("Parent 2");

            UltraTreeColumnSet columnSet1 = new UltraTreeColumnSet();
            columnSet1.Columns.Add("A");
            columnSet1.Columns.Add("B");
            columnSet1.Columns.Add("C");

            parentNode1.Nodes.Override.ColumnSet = columnSet1;

            UltraTreeColumnSet columnSet2 = new UltraTreeColumnSet();
            columnSet2.Columns.Add("1");
            columnSet2.Columns.Add("2");           

            parentNode2.Nodes.Override.ColumnSet = columnSet2;

            UltraTreeNode childNode = parentNode1.Nodes.Add();
            childNode.Cells["A"].Value = "A1";
            childNode.Cells["B"].Value = "B1";
            childNode.Cells["C"].Value = "C1";
            childNode = parentNode1.Nodes.Add();
            childNode.Cells["A"].Value = "A2";
            childNode.Cells["B"].Value = "B2";
            childNode.Cells["C"].Value = "C2";
            childNode = parentNode1.Nodes.Add();
            childNode.Cells["A"].Value = "A3";
            childNode.Cells["B"].Value = "B3";
            childNode.Cells["C"].Value = "C3";

            childNode = parentNode2.Nodes.Add();
            childNode.Cells["1"].Value = "11";
            childNode.Cells["2"].Value = "21";           
            childNode = parentNode2.Nodes.Add();
            childNode.Cells["1"].Value = "12";
            childNode.Cells["2"].Value = "22";
