You can use js:

$(function () {
        $("input").each(function () {
            $(this).val($(this).val().toUpperCase());
        })
    })

It will change all the inputs' values to uppercase when page loaded.If you want to change all my textbox input letters to uppercase when input lose focus,you can use:

 $("input").change(function () {
        $(this).val($(this).val().toUpperCase());
    })
