在SelectedIndexChanged弹出窗口关闭后，ModalPopupExtender包括一个DropDownList？ [英] ModalPopupExtender including a DropDownList after the SelectedIndexChanged popup closing itself?

问题描述

我在我的一个页面上有一个ModalPopupExtender，用于向用户呈现表单，该表单包含几个字段，包括DropDownList，其AutoPostBack属性设置为true。当用户更改DropDownList POSTBACK中的所选项目时，会自动关闭模态弹出窗口。如果我在此时重新打开弹出窗口，则应用了正确的部分更新，但我不希望弹出窗口自行关闭。我怎么能自己停止关闭modalpopupextender。

谢谢。

I have a ModalPopupExtender on one my pages which I am using to render a form to the user, the form contains several fields including a DropDownList with its AutoPostBack property set to true. When the user changes the selected item in the DropDownList POSTBACK occurs and then the modal popup is automatically closed. If I reopen the popup at this point the correct partial updates have been applied, but I do not want the popup to close itself. How can I stop closing modalpopupextender by itself.
Thank you.
