I'm using DevExpress in a Web Project and I'm beginner with this tool. So, here is the thing: I've put a simple ASPXTextBox in an "empty" aspx file to make some tests, but there's a blue mark on the field that should not be there, like the following picture:
And here is the code:
<dx:ASPxTextBox ID="ASPxTextBox1" runat="server" Theme="Metropolis" Width="170px"> </dx:ASPxTextBox>
I'm not using any CSS to change the style, it's just the aspx file and nothing else. Any idea of why this blue mark appears? Thank you.
