Hi Mike,

Thanks for your quick reply. If would be great if you could provide us with a sample code snippet which will illustrate the intended behaviour as we are pretty new to Infragistics.

Thanks in Advance.

Hi Mike,

One more point to be noted here is that we have multiple columns and display of text is w.r.t first column. So the special characters come into picture w.r.t first column and when user selects it, we would like to have the text stripped of all special characters.

Thanks in Advance.

It's hard to give you sample code since I'm really not clear on what your data source looks like.

Typically, you could not use a string as the Value of a combo - most of the time, you would use a numeric key of some sort and then use the ValueMember and DisplayMember so that the user sees a more user-friendly string while at the same time you application deals with the key value.

I'm not sure what you mean in your last post about the first column. The position of the columns is irrelevant. You tell the Combo which column is the value column using the ValueMember property. And you tell the combo which column is the display column via the DisplayMember property.

Here's a simple code snippet which shows you how to add an unbound column to the combo called "My Column". And also shows how to use InitializeRow to get the text from the real column ("Column 0") and set the value of "My Column" to a modified string.

        private void ultraCombo1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            if (false == e.Layout.Bands[0].Columns.Exists("My Column"))
            {
                UltraGridColumn column = e.Layout.Bands[0].Columns.Add("My Column");                
            }
        }

        private void ultraCombo1_InitializeRow(object sender, InitializeRowEventArgs e)
        {
            if (e.Row.Cells.Exists("My Column"))
            {
                string originalText = e.Row.Cells["Column 0"].Text;
                e.Row.Cells["My Column"].Value = originalText.Substring(5);
            }
        }
