如果表中添加的列的絕對值小於8，我試圖更改一行上的背景色。我嘗試了幾種不同的方法，但儘管看起來很接近，但最新的嘗試沒有像我預期的那樣表現出色。根據另一列中的值在ListView上有條件地更改樣式

/* As the connection string to the SQL database is defined as conn, */
/* the open method from conn will connect to the database, and the */
/* cmd variable will call on the stored procedure GetSchedule. */
/**********************************************************************/
string strcon = WebConfigurationManager.ConnectionStrings["FollowingHSFootballConnectionString"].ConnectionString;
using (SqlConnection conn = new SqlConnection(strcon))
{
SqlCommand cmd = new SqlCommand("CurrentSchedScore", conn);
cmd.CommandType = CommandType.StoredProcedure;
conn.Open();
DataTable ScheduleTbl = new DataTable();
SqlDataAdapter da = new SqlDataAdapter(cmd);
// Fill the partial DataSet into a partial DataTable.
da.Fill(ScheduleTbl);
ListView2.DataSource = ScheduleTbl;
ListView2.DataBind();
// Close Game Logic
ScheduleTbl.Columns.Add("Diff", typeof(int), "HomeTeamScore - AwayTeamScore");
ScheduleTbl.Columns.Add("Alert", typeof(string), "");
for (int i = 0; i < ScheduleTbl.Rows.Count; i++)
{
DataRow drST = ScheduleTbl.Rows[i];
if (Math.Abs((int)drST.ItemArray.GetValue(8)) <= 8)
{
drST.BeginEdit();
drST.ItemArray.SetValue("background-color:red", 9);
drST.AcceptChanges();
drST.EndEdit();
}
}
}
}
如果我誤解了如何更新的最後一列？
