我有一個顯示puja.i列表的repeater.i也使用了一個datalist來顯示廟的名字。每當我點擊搜索它只顯示中繼器的最後一個值,即它只取最後一個值中繼器....我的問題是如何使用中繼器內的循環? 這裏是後面我如何使用DataList和Repeater我的代碼:如何迭代使用中繼器?
protected void Page_Load(object sender, EventArgs e)
{
//lblnodatafound.Visible = true;
//lbldatafound.Visible = false;
if (Request.QueryString["search"] != null)
{
var dt = new DataTable("Data");
String source = Request.QueryString["search"];
var splitseparator = new string[] { " " };
String[] result = source.Split(splitseparator, StringSplitOptions.RemoveEmptyEntries);
foreach (String s in result)
{
if (IsAlphaNumeric(s) == true)
{
var dttemp = new DataTable();
dttemp = fnsearch(s);
dt.Merge(dttemp, true);
}
}
if (dt.Rows.Count != 0)
{
int count = dt.Rows.Count;
if (dt.Rows.Count > 0)
{
DataList1.DataSource = dt;
DataList1.DataBind();
lblnodatafound.Visible = false;
lbldatafound.Visible = true;
//added the repeater to display the list of puja
for (int i = 0; i < dt.Rows.Count; i++)
{
String id = dt.Rows[i]["id"].ToString();
string query = "select puja.id,puja.name as puja_name, mandir.name as mandir_name from puja,mandir where mandir.id= puja.with_mandir and puja.with_mandir = '" + id + "'";
conn.Open();
MySqlCommand cmd = new MySqlCommand(query, conn);
MySqlDataAdapter adp = new MySqlDataAdapter(cmd);
DataTable dt1 = new DataTable();
adp.Fill(dt1);
conn.Close();
if (dt1.Rows.Count > 0)
{
lblmandirpuja.Text = "Poja in " + dt1.Rows[0]["mandir_name"];
foreach (RepeaterItem repeatItem in Repeater1.Items){
Repeater1.DataSource = dt1;
Repeater1.DataBind();
}
}
}
}
}
else
{
lblnodatafound.Visible = true;
lbldatafound.Visible=false;
}
}
}
您正在分配循環內的中繼器數據源'for(int i = 0;我
如果我刪除了循環,那麼只有第一個值diplayed,我也必須刪除變量我這樣,因爲變量我不能顯示錶的列表... 。還有另一種可能性嗎? – user3132068
