protected void Button1_Click(object sender, EventArgs e)

        Button gridBtn = (Button)sender;
       //selecting grid row

        //here I used to change color of selected rows
         GridView1_SelectedIndexChanged(GridView1, EventArgs.Empty);
        if (gridBtn != null)
        {
           //changing button text[/color]
            if (gridBtn.Text == "DeSelect")
            { gridBtn.Text = "Select"; }
            else

        }

    }
    protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
    {

        if (GridView1.Rows[sIndex].BackColor == System.Drawing.Color.Red)
        {
            GridView1.Rows[sIndex].BackColor = System.Drawing.Color.White;
        }
        else
        {
            GridView1.Rows[sIndex].BackColor = System.Drawing.Color.Red;
        }

    }

ASPX section

I add One Button field as Template field. and add Button text as "Select". when you click on select button in GridView, the selected Row become Red color.

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
            DataSourceID="SqlDataSource1">
            <columns>
                <asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" />
                <asp:BoundField DataField="Category" HeaderText="Category"
                    SortExpression="Category" />
                <asp:BoundField DataField="Tags" HeaderText="Tags" SortExpression="Tags" />
                <asp:TemplateField>
                    <itemtemplate>
                        <asp:Button ID="Button1" runat="server" Text="Select" onclick="Button1_Click" />
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
