Hello, Shanti,
To customize appearance in
GridViewRatingColumn in
RadGridView you should subscribe to the
CellFormatting event which fires when the content of a data cell needs to be formatted for display. If you would like to customize the element within the cell you should access the
RadRatingElement. Please refer to the following example:
public partial class Form1 : RadForm
{
public Form1()
{
InitializeComponent();
GridViewRatingColumn column = new GridViewRatingColumn("Rating Column");
radGridView1.Columns.Add(column);
radGridView1.Rows.Add(20);
radGridView1.Rows.Add(35);
radGridView1.Rows.Add(70);
radGridView1.Rows.Add(30);
radGridView1.Rows.Add(18);
radGridView1.CellFormatting += RadGridView1_CellFormatting;
}
private void RadGridView1_CellFormatting(object sender, CellFormattingEventArgs e)
{
GridRatingCellElement cell = e.CellElement as GridRatingCellElement;
if (cell!=null )
{
RatingStarVisualElement firstStar = cell.RatingElement.Items[0] as RatingStarVisualElement;
firstStar.ValueElement.Fill.BackColor = Color.Red;
firstStar.ValueElement.Fill.GradientStyle = GradientStyles.Solid;
firstStar.HoverElement.Fill.BackColor = Color.Yellow;
firstStar.HoverElement.Fill.GradientStyle = GradientStyles.Solid;
}
e.CellElement.BackColor = Color.Pink;
e.CellElement.GridViewElement.GradientStyle = GradientStyles.Solid;
}
}

I hope this helps. Should you have any other questions, I will be glad to help.
