中繼器與回發

Question

我有一箇中繼器，每個項目都有一個複選框和單選按鈕。

• 複選框選中時（帶自動回傳）禁止所有的物品內部的控制
• 的單選按鈕，顯示檢查一次（也有自動回傳）一個彈出。

情況是：如果在中繼器的任何項目中都有一個單選按鈕被選中，當我選中複選框控件以禁用項目時，彈出窗口將顯示。在回發期間，選中的單選按鈕將導致彈出窗口顯示。

我該如何預防？複選框應該只禁用不顯示彈出窗口的項目。

    protected void rptr1_ItemDataBound(object sender, RepeaterItemEventArgs e)

不要使用PreRender事件，以決定是否顯示彈出，但使用單選按鈕的OnCheckedChanged事件來證明這一點。

l1.CheckedChanged = (sender, e) => { if (l1.Checked) ModalPopupExtender1.Show(); };
