ModalPopupExtender display

I have a ModalPopupExtender on an aspx page that is displayed by a button. The button is only visible if certain conditions about a patient exist. If these conditions do not exist I would like the button to not display which would then not allow the ModalPopup to display either.

However, whenever I set the button visible property to false the ModalPopup is no longer a Modal Popup but a regular table on the page which always displays.

AjaxControlToolkit - 4.1.7.123

Although I do not think it matters in this case I am using VB.NET as the code behind page.

Does anyone know a work around to this behavior?

Thanks in advance,

Instead of setting the button visibility property to false try setting the style display attribute of the button to none like :

mybutton.style = "display:none"

That definitely suppresses the ModalPopup but...

I have a style for the button in a CSS file that gets applied to buttons in the application. How can I conditionally apply "display:none" in code?

Simple and easy to use.

I have never approach styles in that manner. I'm guessing I can evaluate the Styles Item collection to see if styles exist?

Thank you for your assistance.

Yes you can evaluate the styles collection to see if a style exists, however I think if you add a style that already exists it overwrites its current value, so haven't really found the need to evaluate the collection in that way.

I was more concerned about evaluating to remove the style but the options are a plenty.

There are so many things that just opened up in my world from this little tidbit of information.

Thanks again!
