Hello ehan,

I am glad to hear this!

Please feel free to let me know if a question about our tool set comes up on your mind.

I've moved over to the UltraCombo and now it works. Thanks

Hi,

I don't see you setting the ValueMember here. Is the DisplayMember and the ValueMember the same column? By default, the ValueMember will resolve to the first column, so if your codeColumn is the first one, then the dropdown isn't really translating the value into display text.

Does the text on the code column show up in upper case?

Does the value in the node cell match a value on the dropdown?

If this is not working, then another approach you could take is to use an UltraCombo instead of an UltraDropDown. They both derive from the same base class, so all you could pretty much find/replace UltraDropDown with UltraCombo in this code with two small changes:

1) Set the EditorComponent on the column instead of the ValueList:

treeColumn.EditorComponent = BenchmarkCombo;

2) Set the CharacterCasing on the UltraCombo just like on the UltraTextEditor.

Thanks Mike, I got the column with the text box to work with your suggestion. But I'm still having trouble with the drop down. Below is the code

BenchmarkDropDown = new UWG.UltraDropDown();
UWG.UltraGridColumn idColumn = new UWG.UltraGridColumn("ID");
idColumn.Hidden = true;
idColumn.Header.VisiblePosition = 0;
UWG.UltraGridColumn codeColumn = new UWG.UltraGridColumn("Code");
codeColumn.Header.VisiblePosition = 1;
codeColumn.CharacterCasing = CharacterCasing.Upper;
UWG.UltraGridColumn descriptionColumn = new UWG.UltraGridColumn("Description");
descriptionColumn.Header.VisiblePosition = 2;
((ISupportInitialize) BenchmarkDropDown).BeginInit();
BenchmarkDropDown.DataMember = null;
BenchmarkDropDown.DisplayMember = "Code";
BenchmarkDropDown.DisplayLayout.Bands[0].Columns.AddRange(new object[] { idColumn, codeColumn, descriptionColumn });
BenchmarkDropDown.Visible = false;
BenchmarkDropDown.MaxDropDownItems = 8;
BenchmarkDropDown.DisplayLayout.ScrollBounds = Infragistics.Win.UltraWinGrid.ScrollBounds.ScrollToFill;
BenchmarkDropDown.DisplayLayout.ScrollStyle = UWG.ScrollStyle.Immediate;
BenchmarkDropDown.DisplayLayout.AutoFitStyle = UWG.AutoFitStyle.None;
BenchmarkDropDown.TextRenderingMode = TextRenderingMode.GDI;
((ISupportInitialize) BenchmarkDropDown).EndInit();
BenchmarkComboItems = new ComboItemList();
BenchmarkDropDown.SetDataBinding(BenchmarkComboItems.BindingSource, "", true, true);
BenchmarkDropDown.DisplayLayout.BorderStyle = UIElementBorderStyle.Solid;
BenchmarkDropDown.DisplayLayout.Override.CellAppearance.BackColor = RockitColors.GridDropDownBackground;
BenchmarkDropDown.DisplayLayout.Override.BorderStyleCell = UIElementBorderStyle.Dotted;
BenchmarkDropDown.DisplayLayout.Override.BorderStyleRow = UIElementBorderStyle.Dotted;

treeColumn = new UltraTreeNodeColumn();
treeColumn.Key = BenchmarkColumnKey;
treeColumn.Text = "Benchmark";
treeColumn.AllowCellEdit = AllowCellEdit.Full;
treeColumn.LayoutInfo.AllowLabelSizing = LayoutSizing.None;
treeColumn.MaxLength = 4;
treeColumn.ButtonDisplayStyle = Infragistics.Win.UltraWinTree.ButtonDisplayStyle.OnCellActivate;
treeColumn.ValueList = BenchmarkDropDown;
treeColumnSet.Columns.Add(treeColumn);
