我想隱藏已經添加到表格中的repeater元素,但現在我面臨一些問題,即使我爲比較條件做了一些操作,中繼器也會根據表格顯示出整體內容。這是我的編碼部分。希望會知道我犯的錯誤。隱藏帶條件的Repeater元素
設計師代碼:
<script language="C#" runat="server">
protected void ItemDataBound(object sender, RepeaterItemEventArgs e)
{
String personID = "";
try
{
MySql.Data.MySqlClient.MySqlConnection connStr = new MySql.Data.MySqlClient.MySqlConnection();
connStr.ConnectionString = "Server = localhost; Database = healthlivin; Uid = root; Pwd = khei92;";
String searchPerson = "SELECT PersonIDB from contactFriend WHERE PersonID = @id";
MySql.Data.MySqlClient.MySqlCommand cmdSearch = new MySql.Data.MySqlClient.MySqlCommand(searchPerson, connStr);
connStr.Open();
cmdSearch.Parameters.AddWithValue("@id", "M000001");
MySql.Data.MySqlClient.MySqlDataReader dtrRead2 = cmdSearch.ExecuteReader();
if (dtrRead2.Read())
{
personID = (String)dtrRead2["PersonIDB"];
}
dtrRead2.Close();
connStr.Close();
