OnSelectedIndexChanged="lvCustomers_SelectedIndexChanged1"
OnItemCanceling="lvCustomers_ItemCanceling"
onitemupdating="lvCustomers_ItemUpdating"
onitemdatabound="lvCustomers_ItemDataBound">

<%----%>

 

 

code///

 

 

public partial class WebForm2 : System.Web.UI.Page
{
DataTable dt = new DataTable();

protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
DataTable dt = new DataTable();
dt.Columns.AddRange(new DataColumn[2] { new DataColumn("Name"), new DataColumn("Country") });
ViewState["Customers"] = dt;

this.BindGrid();
}
}
protected void BindGrid()
{
lvCustomers.DataSource = (DataTable)ViewState["Customers"];
lvCustomers.DataBind();
}
protected void Insert(object sender, EventArgs e)
{
DataTable dt = (DataTable)ViewState["Customers"];

dt.Rows.Add(txtName.Text.Trim(), txtCountry.Text.Trim());
ViewState["Customers"] = dt;
this.BindGrid();
txtName.Text = string.Empty;
txtCountry.Text = string.Empty;
} 

Do you want to store the data permanently . If so where do you intend to store them .

 

Thanks,
