Hi,
Your query seems to be perfect. Just try using this:

C#

protected void DeleteRecord(object sender, GridViewDeleteEventArgs e)
    {
         string id = gridRegistrationTableDetails.Rows[e.RowIndex].Cells[0].Text;
         deleterecordMethod(id);
         BindData();
    }
    private void deleterecordMethod(string id)
    {
        try
        {
            SqlConObject.Open();
            SqlCommand cmd = new SqlCommand("delete from SignUp where Employee_ID=@EmpID", SqlConObject);
            cmd.Parameters.AddWithValue("@EmpID", id);
            cmd.ExecuteNonQuery();
        }
        catch(Exception e)
        {
            Response.Write("<script>alert('Exception Occurred')</script>"+e);
        }
        finally
        {
            SqlConObject.Close();
        }
    }

As I see there is no problem in your code neither in Amit's answer, if you simply wanna see change in grid instantly then:

C#

private void deleterecordMethod(string id)
    {
        string Query = "delete from SignUp where Employee_ID=@EmpID";
        try
        {
            SqlConObject.Open();
            SqlCommand cmd = new SqlCommand(Query, SqlConObject);
            cmd.Parameters.AddWithValue("@EmpID", id);
            cmd.ExecuteNonQuery();
            //Call your FillGrid() method here to see effect in gridview.
        }
        catch(Exception e)
        {
            Response.Write("<script>alert('Exception Occurred')</script>"+e);
        }
        finally
        {

            SqlConObject.Close();
        }
    }
