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.
