Follow these steps-

1. design you page like this-

<asp:Button ID="btnGetDetails" runat="server" Text="Button"

onclick="btnGetDetails_Click1" OnClientClick ="return confirmation()"/>

<asp:GridView ID="GridView1" runat="server">

</asp:GridView>

<asp:DropDownList ID="DropDownList1" runat="server"

onselectedindexchanged="DropDownList1_SelectedIndexChanged">

</asp:DropDownList>

2. Write this code and code behind-

protected void btnAdd_Click1(object sender, EventArgs e)

{

DataSet dataSet1 = (DataSet)GridView1.DataSource;

string s = DropDownList1.SelectedItem.ToString() ;

DataRow foundRow = dataSet1.Tables[0].Rows.Find(s);

if (foundRow != null)

{

Label1.Text = "Record already Exist.";

}

else

{

DataRow dr = dataSet1.Tables[0].NewRow();

dataSet1.Tables[0].Rows.Add(dr);

GridView1.DataSource = dataSet1;

GridView1.DataBind();

}

}


Try this and let me know.

Hi,

/* Add new Row */ 
dataGridView1.Rows.Add();
   
/* Set the cell values of newly added row*/
int index = dataGridView1.Rows.Count-1;
dataGridView1.Rows[index].Cells[0].Value = "Some value";
dataGridView1.Rows[index].Cells[1].Value = "Some Value2"

Add() method will add Blank Row to Grid after adding it you can change the cell values as you need . 

Hope this will help you
