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: 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.
