Hi Praveen
Try this

on your button click

C#

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

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

JavaScript

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

Hope it will help you

Thanks

Solution 3

write this code on the click of your button

C#

if(!string.IsNullOrEmpty(txtName.text))
this.modalpopup.show();

dont set the target controlid of your button same as this button as it will not allow to post back and fire the click event.

Feel free to ask any another doubt regarding the same.
