Instead of doing so much hardwork you can achieve this on the same page with a little bit of extra code.
Workaround
Add a client alert script to the delete button of every row.
In the delete event of GridView delete the record.

1) Import Namespaces
using System.Data.SqlClient;
2) Declare global variables which will be used in page
DataSet ds = new DataSet();
SqlDataAdapter da;
SqlConnection myConnection;
String connStr = "your database connection string goes here"';
String sql = string.Empty;
3) Page Load event
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack == false)
{
fillGridView();
}
}
4) GridView filling method
private void fillGridView()
{
try
{
myConnection = new SqlConnection(connStr);
sql = "select * from tblFaq order by slno desc";
da = new SqlDataAdapter(sql, myConnection);
ds.Clear();
da.Fill(ds, "tblFaq");
gvFaq.DataSource = ds.Tables[0];
Page.DataBind();
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
}
5) In the RowDataBound event add a java script event to the delete cell.
protected void gvFaq_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Cells[4].Attributes.Add("onClick", "return confirm('Are you sure you want to delete the record?');");
}
}
6) Handle the RowDeleting event to delete the record of current row.
protected void gvFaq_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
try
{
myConnection = new SqlConnection(connStr);
myConnection.Open();
sql = "delete from tblFaq where slno = " + Convert.ToInt32(gvFaq.Rows[e.RowIndex].Cells[0].Text);
SqlCommand oldcom = new SqlCommand(sql, myConnection);
oldcom.ExecuteNonQuery();
myConnection.Close();
fillGridView();
Response.Write("Record Deleted");
}
catch (Exception ex)
{
lblError.Text = ex.Message;
}
}
