You need to create Bound Columns with column names from DB table you going to bind. After creation just bind the datatable to the gridview datasource.

Take a button control in footer as AddNewRow then on click event of that button call the below code For example: public void AddNewRow() { DataTable dt = new DataTable(); dt.Columns.Add(SrNo typeof(int)); dt.Columns.Add(Name typeof(string)); dt.Columns.Add(City typeof(string)); foreach (GridViewRow grv in GridView1.Rows) { DataRow dtrow; dtrow = dt.NewRow(); dtrow[SrNo] = ((Label)grv.FindControl(lblSrNo)).Text; dtrow[Name] = ((TextBox)grv.FindControl(txtName)).Text; dtrow[City] = ((TextBox)grv.FindControl(txtCity)).Text; dt.Rows.Add(dtrow); } DataRow dtrow1; dtrow1 = dt.NewRow(); dt.Rows.Add(dtrow1); GridView1.DataSource = dt; GridView1.DataBind(); } protected void btnAddNewRow_Click(object sender EventArgs e) { AddNewRow(); }
