I am working with Asp.Net and Bootstrap. I have: a Button, a TextBox and a Label, I give a value to the TextBox I press the button and I add that value + 2, it shows it in the Label. Up there all good. But if that number is less than 0 I want me to load a modal. You can help me with a simple example to load that modal. Because it asks me for a Scriptmanager I add it and even then it does not load when I give it a negative value. Thanks
