Telerik.WebControls.RadAjaxManager 导致下拉列表未触发处理程序
我的前端代码如下
所示asp:dropdownlist id="cbo" runat="服务器" CssClass="combobox" AutoPostBack="True" 宽度="100%" > < asp:ListItem Selected="True" Value="A">A < asp:ListItem Value="B">B < /asp:下拉列表>
< rada:RadAjaxManager id="RadAjaxManager1" runat="服务器"> < Ajax设置> < rada:AjaxSetting AjaxControlID="cbo"> <更新控件> < rada:AjaxUpdatedControl ControlID="cbo" /> < /更新的控件> < /rada:Ajax 设置> < /Ajax设置> < /rada:RadAjaxManager >
在我后面的代码中，我有下拉列表的处理程序
Private Sub cbo_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cbo.SelectedIndexChanged
textBox1.text = cbo.selectedvalue End Sub
但是下拉列表在更改时不会触发处理程序。当我删除 Telerik radajaxmanager 时，它会触发。任何人都知道为什么会发生这种情况。请帮忙。
I have a front end code look like below
< asp:dropdownlist id="cbo" runat="server" CssClass="combobox" AutoPostBack="True" Width="100%" >
< asp:ListItem Selected="True" Value="A">A
< asp:ListItem Value="B">B
< /asp:dropdownlist>
< rada:RadAjaxManager id="RadAjaxManager1" runat="server">
< AjaxSettings>
< rada:AjaxSetting AjaxControlID="cbo">
< UpdatedControls>
< rada:AjaxUpdatedControl ControlID="cbo" />
< /UpdatedControls>
< /rada:AjaxSetting>
< /AjaxSettings>
< /rada:RadAjaxManager >
In my code behind, I have the handler for the dropdownlist
Private Sub cbo_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cbo.SelectedIndexChanged
textBox1.text = cbo.selectedvalue
End Sub
But the drop down do not fire the handler when it is change. When I remove the telerik radajaxmanager, it will fire. Any one have idea why this will happen. Please help.

该处理程序可能已被触发，但要在文本框中设置文本，您必须将其 ID (textBox1) 添加到 ajax 管理器设置的 UpdatedControls 集合中。
The handler is probably fired, but to set text in the textbox you have to add its ID (textBox1) in the UpdatedControls collection of the ajax manager setting.
