Hi,

Okay, so you are probably using the InitializeRow event and setting the Appearance on the cell. But that won't have any effect on the button, only on non-button cells. You need to use the ButtonAppearance property on the cell, instead.

Also, by default, the buttons in the grid are drawn using OS Themes, which means you cannot change the colors. Themed drawing is all or nothing. So if you want to change the colors of the buttons, you have to turn off themes.

You can turn off themes on the entire grid with the UseOsThemes property.

You could turn off themes on the entire application using AppStylist.

Or, you could turn off themes just on the buttons by setting the ThemedElementAlpha on the ButtonAppearance to Transparent.

Here's some quick sample code to point you in the right direction.

        private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            UltraGridLayout layout = e.Layout;
            UltraGridBand band = layout.Bands[0];
            UltraGridOverride ov = layout.Override;

            band.Columns["String 1"].Style = Infragistics.Win.UltraWinGrid.ColumnStyle.Button;

            if (false == layout.Appearances.Exists("Yellow"))
            {
                Infragistics.Win.Appearance yellowAppearance = layout.Appearances.Add("Yellow");
                yellowAppearance.ThemedElementAlpha = Alpha.Transparent;
                yellowAppearance.BackColor = Color.Yellow;
                yellowAppearance.ForeColor = Color.Black;
            }

            if (false == layout.Appearances.Exists("Green"))
            {
                Infragistics.Win.Appearance greenAppearance = layout.Appearances.Add("Green");
                greenAppearance.ThemedElementAlpha = Alpha.Transparent;
                greenAppearance.BackColor = Color.Green;
                greenAppearance.ForeColor = Color.Black;
            }
        }       

        private void ultraGrid1_InitializeRow(object sender, InitializeRowEventArgs e)
        {
            int i = (int)e.Row.Cells["Int32 1"].Value;
            if (i < 0)
                e.Row.Cells["String 1"].Appearance = e.Row.Band.Layout.Appearances["Yellow"];
            else
                e.Row.Cells["String 1"].Appearance = e.Row.Band.Layout.Appearances["Green"];
        }

Hi Mike,

Thank you for the quick response. I would potentially need to change the color on each row.

Thanks!
