When i updating cell date in gridview then it is raising issue of

String was not recognized as a valid DateTime.

In Sql table date column type is datetime

What I have tried:

        protected void GridView3_RowUpdating(object sender, GridViewUpdateEventArgs e)
        {
     DateTime date2 = Convert.ToDateTime(txtEntryDate.Text);  //Issue in this Code///
           
      GridViewRow row = GridView3.Rows[e.RowIndex];
            int customerId = Convert.ToInt32(GridView3.DataKeys[e.RowIndex].Values[0]);
            string name = (row.FindControl("txtName") as TextBox).Text;
            string country = (row.FindControl("txtCountry") as TextBox).Text;
            string EntryDate = (row.FindControl("txtEntryDate") as TextBox).Text;
            string query = "UPDATE Country SET Name=@Name, Country=@Country, EntryDate=@date2 WHERE CustomerId=@CustomerId";
            con = new SqlConnection("Data Source=DESKTOP-5PJ76B9;Integrated Security=SSPI;Initial Catalog=Institute");
                     {
                using (SqlCommand cmd = new SqlCommand(query))
                {
                    cmd.Parameters.AddWithValue("@CustomerId", customerId);
                    cmd.Parameters.AddWithValue("@Name", name);
                    cmd.Parameters.AddWithValue("@Country", country);
                    cmd.Parameters.AddWithValue("@date2", EntryDate);
                    cmd.Connection = con;
                    con.Open();
                    cmd.ExecuteNonQuery();
                    con.Close();
                }
            }
            GridView3.EditIndex = -1;
            this.BindGrid();
        }
    }
}

Try using DateTime.ParseExact

Simple: it isn't a valid date.
It may be to you, and your user - but SQL runs on a different computer and doesn't have access to your users preferences. Instead of passing everything to SQL as a string, use the various TryParse methods to convert them to native types (using the user settings to get it right) and pass the converted value directly to SQL.

C#

DateTime datEntry;
it (!DateTime.TryParse(EntryDate, out datEntry))
   {
   ... report format / value problem to user ...
   return;
   }
...
cmd.Parameters.AddWithValue("@date2", datEntry);
