验证后未显示ModalPopupExtender [英] ModalPopupExtender not displaying after validation

问题描述

我有一个带有三个文本字段和提交按钮的modalpopupextender.
所有字段都是必填字段，因此我给出了要在模式弹出窗口中显示的消息.
当我单击链接按钮时，将显示此模式弹出窗口.
当我在没有任何文本框中输入值的情况下按确定按钮时，modalpopup消失.
再次单击链接按钮时，它会显示带有验证消息的modalpopup.

在此先感谢

I have a modalpopupextender with threee text fields and submit button.
All the fields are mandatory, hence I have given message to display in the modal popup.
This modalpop will be displayed when I click a linkbutton.
When I press the ok button without giving the value in any of the text boxes, the modalpopup disappears.
Again when I click the link button it shows the modalpopup with the validation message.

Thanks in advance
