Step 1

(Add the following code to your Default.aspx page)

<div>

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" onrowdatabound="GridView1_RowDataBound"
 AutoGenerateColumns="False" CellPadding="4">
 <RowStyle BackColor="Beige" ForeColor="#333333" HorizontalAlign="Center" Font-Bold="true"/>

<Columns>

<asp:BoundField DataField="TYPE" HeaderText="Type" />
 <asp:BoundField DataField="CHANNEL" HeaderText="Chanel" />
 <asp:BoundField DataField="CALLERID" HeaderText="Caller ID" />

<asp:BoundField DataField="RINGING_TIME" HeaderText="RingDuration" />
 <asp:BoundField DataField="DURATION" HeaderText="CallDuration" />
 </Columns>

</asp:GridView></div>

Step 2

On the RowDataBound event of the GridView write the following code

 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (e.Row.Cells[0].Text == "INCOMING")
{
e.Row.Font.Bold = false;
e.Row.BackColor = System.Drawing.Color.Red;

}

}
}
