Hi,

An easy way to change the RadGrid sort arrows is to use the SortAscImageUrl and SortDescImageUrl properties, which are set per column.
More information is available in this link:
Basic Sorting(Customizing the sorting arrows)

Thanks,

Hi Nithya Rani,

I guess you want to add an image next to the HeaderText of a column indicating the column can be sorted and removing it on sorting. Please take a look into the following code snippet.

C#:

protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    if (e.Item is GridHeaderItem)
    {
        GridHeaderItem header = (GridHeaderItem)e.Item;
        Image img = Image();
        img.ID = "Image1";
        img.ImageUrl = "~/Images/Sort.gif";
        header["ColumnUniqueName"].Controls.AddAt(1, img);
        if (RadGrid1.MasterTableView.SortExpressions.Count > 0 && RadGrid1.MasterTableView.SortExpressions[0].FieldName == "ColumnFieldName")
        {
            if (RadGrid1.MasterTableView.SortExpressions[0].SortOrder == GridSortOrder.Ascending || RadGrid1.MasterTableView.SortExpressions[0].SortOrder == GridSortOrder.Descending)
            {
                header["ColumnUniqueName"].Controls.Remove(img);
            }
        }
    }
}

Thanks,
Princy.
