我在我的 Web 应用程序中使用 Ajax ControlToolkit 中的 ModalPopupExtender。我将它的 Drag 属性设置为 true,但是当我将弹出面板拖放到新位置时,它立即回到原来的位置。我想得到效果像示例一样,可以拖放到不同的位置。如何在页面上的示例中..

这是我的代码:
<form id="form1" runat="server">
<asp:scriptmanager id="ScriptManager1" runat="server">
</asp:scriptmanager>
<asp:button id="btnAddNew" runat="server" text="New Expanse" />
<asp:modalpopupextender id="ModalPopupExtender1"
runat="server" cancelcontrolid="btnCancel"
okcontrolid="btnOkay" targetcontrolid="btnAddNew"
popupcontrolid="Panel1" popupdraghandlecontrolid="PopupHeader"
drag="true" backgroundcssclass="ModalPopupBG">
</asp:modalpopupextender>
<div class="popupConfirmation" id="Panel1" style="display: none">
<iframe id="frameeditexpanse" src="Benutzer.aspx" frameborder="1" height="500px" width="520px">
</iframe>
<div class="popup_Buttons" style="display: none">
<input id="btnOkay" type="button" value="Speichern" />
<input id="btnCancel" type="button" value="Abbrechen" />
</div>
</div>
PS:如果对话框打开,我想在后台的文本框中输入。
更新:
