Dynamically adding Table rows

Question

I am trying to add values in table rows on button click. It's working on database but not working on web page. It override on last row on page.

How can I generate new row on every button click.

here is my button click code--

protected void Page_Load(object sender, EventArgs e)
{
 tblAdd.Visible = false;
 Label1.Visible = false;
 //Label2.Visible = false;
}
protected void btnSave_Click(object sender, EventArgs e)
{
 if (Page.IsValid)
 {
 CheckBox cb1 = new CheckBox();
 I = Hidden1.Value;
 I += 1;
 cb1.ID = "cb1" + I;
 TableRow Table1Row = new TableRow();
 Table1Row.ID = "Table1Row" + I;
 TableCell RCell1 = new TableCell();
 RCell1.Controls.Add(cb1);
 TableCell RCell2 = new TableCell();
 RCell2.Text = txtName.Text;
 tblLanguagesRow.Cells.Add(RCell1);
 tblLanguagesRow.Cells.Add(RCell2);
 tblLanguages.Rows.Add(tblLanguagesRow);
 Hidden1.Value = I;
 btnAdd.Visible = true;
 btnDelete.Visible = true;
 Label2.Visible = true;
 Label2.Text = "Successfully Added";
 add();
 }
 txtName.Text = "";
}
public int add()
{
 string strcon = ConfigurationManager.ConnectionStrings["Dbconnection"].ConnectionString;
 SqlConnection sqlConnection = new SqlConnection(strcon);
 SqlCommand command = new SqlCommand("hrm_AddLanguages", sqlConnection);
 command.CommandType = CommandType.StoredProcedure;
 command.Parameters.Add("@Name", SqlDbType.VarChar).Value = txtName.Text;
 command.Parameters.Add("@CreatedOn", SqlDbType.DateTime).Value = DateTime.Now;
 command.Parameters.Add("@UpdatedOn", SqlDbType.DateTime).Value = DateTime.Now;
 command.Parameters.Add("@CreatedBy", SqlDbType.BigInt).Value = 1;
 command.Parameters.Add("@UpdatedBy", SqlDbType.BigInt).Value = 1;
 command.Parameters.Add("@IsDeleted", SqlDbType.Bit).Value = 0;
 sqlConnection.Open();
 return command.ExecuteNonQuery();
}

Please Help me.

• kostas ch.: What code have in Page_Load ?
• Azhar Shahid: Added page_Load code.
• kostas ch.: Where do you fill the table? When the button is pressed create post-back and the page reloads. So logically your table should be empty. Am i wrong?
• Azhar Shahid: How to fill table. I know how to bind gridview. But how can I bind table.
• Azhar Shahid: any suggestion please !

If possible try to do this using Grid view. It is better to use grid view instead of table.
