Hi Vishnu,

You can use the DefaultLabelValue="#%" property. For example:

ASPX:

<telerik:RadChart ID="RadChart1" runat="server" Width="540px" Height="330px" DefaultType="Pie" ChartTitle-TextBlock-Text="Summary Chart">
    <Series>
        <telerik:ChartSeries Type="Pie" DataYColumn="Hits" DefaultLabelValue="#%">
            <Appearance LegendDisplayMode="ItemLabels" />
        </telerik:ChartSeries>
    </Series>
</telerik:RadChart>

C#:

protected void Page_Load(object sender, EventArgs e)
{
    RadChart1.DataSource = GetData();
    RadChart1.DataBind();
}

protected DataTable GetData()
{
    DataTable dt = new DataTable();

    dt.Columns.Add("ID", typeof(int));
    dt.Columns.Add("PageName", typeof(string));
    dt.Columns.Add("Hits", typeof(double));

    dt.Rows.Add(1, "Q1", 7);
    dt.Rows.Add(2, "Q2", 6);
    dt.Rows.Add(3, "Q3", 3);
    dt.Rows.Add(4, "Q4", 4);

    return dt;
}

More information on the matter is available in DefaultLabelValue help article.
