html - Text of Asp:button not visible

Question

I am using asp.net core.

I have the following code:

<asp:Button ID="updateNotesBtn" Text="&#10004;" runat="server" OnClick="Click"/>

When I run the web app I can see that the button is visible within the HTML, however the text refuses to display. Hovering over the item reveals that a height is missing:

However when I add a height, I still can't see the text, which should display as: ?. That symbol is displayed elsewhere so that can't be the problem.

Is there something I'm missing?

Answer 1

asp:Button is an ASP.NET WebForms control. If you put this markup on a Razor page, it will simply render as an asp:Button element on your page without any WebForms functionality.

Options:

• rewrite your code to Razor.
• switch back from ASP.NET Core to ASP.NET WebForms.
