推荐答案

嗨Praveen
试试这个

在您的按钮上单击

Hi Praveen
Try this

on your button click

if(!string.isnullorempty(txtName.text))
Modelpopup.show();
else
modelpopup.hide();

您还可以使用按钮
的Java脚本onclientclick事件来实现此目的

You can alse achive this using the java script onclientclick event of button

txtName=

get(" ).value ModalPopupExtender1 =

get("<%= txtName.ClientID %>").value ModalPopupExtender1=

find(" ).Value; 如果(txtName！= 空) ModalPopupExtender1.show(); 其他 ModalPopupExtender1.hide();

find("<%=ModalPopupExtender1.ClientID %>").Value; if(txtName !=null) ModalPopupExtender1.show(); else ModalPopupExtender1.hide();

希望对您有帮助

谢谢
