Hi Xavier,

What kind of case sensitivity are you seeing here? There's nothing in this code that would make the ValueList do any kind of string comparison, so I'm not sure what we're talking about.

I assume you must mean the AutoSuggest functionality. But it's not case sensitive as far as I know.

I tried it out by creating a ValueList with some duplicate texts that differ only by case:

        private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            UltraGridLayout layout = e.Layout;
            ValueList vl = layout.ValueLists.Add("MyValueList");
            vl.ValueListItems.Add(0, "apple");
            vl.ValueListItems.Add(1, "APPLE");
            vl.ValueListItems.Add(2, "banana");
            vl.ValueListItems.Add(3, "BANANA");
            
            UltraGridBand band = layout.Bands[0];
            band.Columns["Column 0"].ValueList = vl;

        }

If I enter a cell in this column and enter a capital "A", it selects "apple" in lower case, since that's the first item on the list that begins with "a" regardless of case.

I have attached my sample here in case you want to try it out on your machine and see if you get the same results.
