Use rowcommand event of GridView

 <asp:GridView id="ProductsGridView"
        DataSourceID="ProductsDataSource"
        DataKeyNames="ProductID"
        AllowPaging="True"
        OnRowCommand="ProductsGridView_RowCommand"
        AutoGenerateColumns="False"
        runat="server">
        <Columns>
          <asp:BoundField DataField="Name" HeaderText="Product Name" />
          <asp:BoundField DataField="ProductNumber" HeaderText="Product Number" />          
          <asp:TemplateField HeaderText="Price">
            <ItemTemplate>
              <asp:Label ID="PriceLabel" runat="server"
                Text='<%# Bind("ListPrice") %>'>
              </asp:Label>
            </ItemTemplate>
          </asp:TemplateField>
          <asp:TemplateField>
            <ItemTemplate>                
              <asp:Button runat="server" ID="IncreaseButton"
                Text="Increase Price 5%"
                CommandName="Increase"
                CommandArgument="<%# ((GridViewRow) Container).RowIndex %>" />
            </ItemTemplate>
          </asp:TemplateField>
        </Columns>
      </asp:GridView>

 void ProductsGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
  {
    // If multiple buttons are used in a GridView control, use the
    // CommandName property to determine which button was clicked.
    if(e.CommandName=="Increase")
    {
      // Convert the row index stored in the CommandArgument
      // property to an Integer.
      int index = Convert.ToInt32(e.CommandArgument);
              Response.Redirect("yourpage.aspx?i="+index );
      }
  }
