基于绑定数据创建ID为的动态DataList控件

你可以使用和我在书中写的相似的技巧 this answer

<ItemTemplate>
    <tr>
        <td>
            <asp:CheckBox runat="server" ID="MyCheckBox" AutoPostBack="true" oncheckedchanged="MyCheckBox_CheckedChanged"  />
            <asp:HiddenField runat="server" id="DatabaseKeyHiddenField" Value='<%# Eval("DatabaseKey") %>' />
        </td>
    </tr>
</ItemTemplate>

protected void MyCheckBox_CheckedChanged(object sender, EventArgs e)
{
    CheckBox selectedCheckBox;
    DataListItem selectedDataListItem;
    HiddenField databaseKeyHiddenField;
    string databaseKey;

    // Cast the sender object to a CheckBox
    selectedCheckBox = (CheckBox)sender;

    // Walk up the tree one level so we get the container for both controls
    selectedDataListItem = (DataListItem)selectedCheckBox.Parent;

    // Get the HiddenField control ...
    databaseKeyHiddenField = (HiddenField)selectedDataListItem.FindControl("DatabaseKeyHiddenField");

    // ... and read the value
    databaseKey = databaseKeyHiddenField.Value;

    // Go off and do a database update based on the key we now have
    ...
}

这是一个解决办法,而不是 你想做什么,但它的工作!
