Hello,

I want define column to comboBox. I write this code:

private static void prvLoadCombobox(ComboBoxCellType linkCombo, ParamInfo paramInf)

string name;

int val;

string[] items, itemData;

items = new string[paramInf.NumOptions];

itemData = new string[paramInf.NumOptions];

for (int eachItem = 0; eachItem < paramInf.NumOptions; eachItem++)

paramInf.GetOption(eachItem, out name, out val);

linkCombo.EditorValue = EditorValue.ItemData;

linkCombo.MaxDrop = Defines.MAX_DROP_LINKS;

But when using the comboBox in the first time I can open it and close it without select any item.

After the first selection always one of the option is selected.

I need that to fix the first time. How I do it?

Sim,

I used the below snippet to set a combobox column and I did not see the behavior as described by you.

        Dim cbox As New FarPoint.Win.Spread.CellType.ComboBoxCellType
        Dim str() As String
        str = New String() {"One", "Two"}
        cbox.Items = str
        FpSpread1.Sheets(0).Columns(0).CellType = cbox

I used VB.net, you can convert the above to equivalent C# code using this one of many online sites available.
