I have added Label in ID column as you have suggested.
HTML:
<form id="form1" runat="server">
<div>
Enter the Id like Abc001
<asp:TextBox ID="txtSerials" runat="server" /><br />
Enter Numbers of rows you want
<asp:TextBox ID="txtNumbsers" runat="server" /><br />
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="true">
<Columns>
</Columns>
</asp:GridView>
<asp:Button ID="btnGenerateRow" runat="server" OnClick="GenerateRows" Text="Generate Rows" />
</div>
</form>
C#:
/// <summary>
/// Create the Gridview with DataTable
/// </summary>
private void CreateGridView()
{
int numbers = int.Parse(this.txtNumbsers.Text.Trim());
DataTable dt = new DataTable();
//you can add as many rows you want
dt.Columns.Add("ID", typeof(string));
dt.Columns.Add("Name", typeof(string));
dt.Columns.Add("Number", typeof(int));
for (int i = 0; i < numbers; i++)
{
//dont forget to add null values in each column
dt.Rows.Add("", "", null);
}
GridView1.DataSource = dt;
GridView1.DataBind();
}
protected void GenerateRows(object sender, EventArgs e)
{
this.CreateGridView();
int numbers = int.Parse(this.txtNumbsers.Text.Trim());
string serialNumber = this.txtSerials.Text.Trim();
string newSerialNumber = serialNumber.Substring(0, serialNumber.Length - 2);
//Here i am adding label if you dont want it then comment till end of for loop
int cellCount = this.GridView1.Rows[0].Cells.Count;
int rowsCount = this.GridView1.Rows.Count;
foreach (GridViewRow row in this.GridView1.Rows)
{
Label label = new Label();
label.ID = newSerialNumber + (Convert.ToInt32(row.RowIndex + 1)).ToString();
label.Text = newSerialNumber + (Convert.ToInt32(row.RowIndex + 1)).ToString();
label.Attributes.Add("runat", "server");
label.CssClass = "Color";
row.Cells[0].Controls.Add(label);
}
foreach (GridViewRow row in this.GridView1.Rows)
{
TextBox textBox = new TextBox();
textBox.ID = newSerialNumber + (Convert.ToInt32(row.RowIndex + 1)).ToString();
// textBox.Text = newSerialNumber + (Convert.ToInt32(row.RowIndex + 1)).ToString();
textBox.Attributes.Add("runat", "server");
textBox.BackColor = Color.Pink;
row.Cells[1].Controls.Add(textBox);
}
foreach (GridViewRow row in this.GridView1.Rows)
{
TextBox textBox = new TextBox();
textBox.ID = newSerialNumber + (Convert.ToInt32(row.RowIndex + 1)).ToString();
// textBox.Text = newSerialNumber + (Convert.ToInt32(row.RowIndex + 1)).ToString();
textBox.Attributes.Add("runat", "server");
textBox.BackColor = Color.Pink;
row.Cells[2].Controls.Add(textBox);
}
}
Namespace:
using System.Data;
using System.Drawing;
Output:
