WinForms Data Grid - Highlight cell text that matches the filter (Auto Filter Row)

This example handles the CustomDrawCell event to highlight cell text that matches the text in the corresponding cell in the auto filter row.

private void gridView1_CustomDrawCell(object sender, RowCellCustomDrawEventArgs e) {
    GridView view = (GridView)sender;
    if (!view.OptionsView.ShowAutoFilterRow || !view.IsDataRow(e.RowHandle))
        return;

    string filterCellText = view.GetRowCellDisplayText(GridControl.AutoFilterRowHandle, e.Column);
    if (String.IsNullOrEmpty(filterCellText))
        return;

    int filterTextIndex = e.DisplayText.IndexOf(filterCellText, StringComparison.CurrentCultureIgnoreCase);
    if (filterTextIndex == -1)
        return;
    e.Appearance.FillRectangle(e.Cache, e.Bounds);
    e.Cache.Paint.DrawMultiColorString(e.Cache, e.Bounds, e.DisplayText, filterCellText, e.Appearance, Color.Black, Color.Gold, false, filterTextIndex);
    e.Handled = true;
}
