Hi,
Count the Gridview Rows and then Add the Values by using the counted Rows Values
like the Below code(it C# Windows Application Code)

string dates= textBox1.Text.ToString();
int i=dataGridView1.Rows.Count;
int j=i-1;
this.dataGridView1.Rows.Add();
dataGridView1.Rows[j].Cells[0].Value=dates;
textBox1.Text="";
Thanks

public partial class test : System.Web.UI.Page
{
DataTable tb = new DataTable();

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
createtable();

}
protected void Button1_Click(object sender, EventArgs e)
{

tb = (DataTable)ViewState["table1"];
tb.Rows.Add(TextBox1.Text, tb.Rows.Count + 1);
GridView1.DataSource = tb;
GridView1.DataBind();

}
public void createtable()
{

tb.Columns.Add("Name", typeof(string));
tb.Columns.Add("Id", typeof(int));
ViewState["table1"] = tb;
}

}

public partial class test2 : System.Web.UI.Page
{
static DataTable table1 = new DataTable();

protected void Page_Load(object sender, EventArgs e)
{

}
protected void Button1_Click(object sender, EventArgs e)
{
Int32 Rcount =table1.Rows.Count;

if (Rcount == 0)
{
table1.Columns.Add("FName");
table1.Rows.Add(TextBox1.Text);

}
else
{
DataRow dr = table1.NewRow();
dr["FName"] = TextBox1.Text;
table1.Rows.Add(dr);

}
GridView1.DataSource = table1;
GridView1.DataBind();
}
}
