<asp:Button ID="Btn_AddNewItem" runat="server" CommandName="AddNewItem" Text="Add" />
</EmptyDataTemplate>

public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindData();
}
}
private void BindData()
{
string connectionString = "Server=localhost;Database=Northwind;Trusted_Connection=true";
SqlConnection myConnection = new SqlConnection(connectionString);
SqlDataAdapter ad = new SqlDataAdapter("SELECT * FROM categories where id = 100", myConnection);
DataSet ds = new DataSet();
ad.Fill(ds);
gvCategories.DataSource = ds;
gvCategories.DataBind();
}
protected void gvCategories_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName.Equals("AddNewItem"))
{
GridViewRow row = (GridViewRow)((e.CommandSource as Button).NamingContainer);
string categoryName = (row.FindControl("txtCategoryName") as TextBox).Text;
