Hi,

The reason is i think you have not stored the data some where and need to add from the stored data.

I have done the example page. You can change the field name or design.

Design page:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="AddRows.aspx.cs" Inherits="Corner_AddRows" %>

Untitled Page

Enter the First Name:
Enter the Last Name:

Width="544px">

Code File:

protected void Page_Load(object sender, EventArgs e)

{

if (Session["UsersTable"] != null)

{

DataTable dt = (DataTable)Session["UsersTable"];

}

private void BindTable(DataTable dt)

{

gvList.DataSource = dt;

gvList.DataBind();

Session["UsersTable"] = dt;

}

protected void btnAdd_Click(object sender, EventArgs e)

{

DataTable dtCurrent = null;

if (Session["UsersTable"] != null)

{

dtCurrent = (DataTable)Session["UsersTable"];

}

else

{

dtCurrent = CreateTable();

}

DataRow dRow = dtCurrent.NewRow();

dRow["FName"] = txtFirstName.Text.Trim();

dRow["LName"] = txtLastName.Text.Trim();

dtCurrent.Rows.Add(dRow);

BindTable(dtCurrent);

}

private DataTable CreateTable()

{

DataTable dtable = new DataTable();

DataColumn dColumn = null;

DataRow dRow = null;

dColumn = new DataColumn();

dColumn.ColumnName = "FName";

dtable.Columns.Add(dColumn);

dColumn = new DataColumn();

dColumn.ColumnName = "LName";

dtable.Columns.Add(dColumn);

return dtable;

}

Hope this will help you.
