Typing in uppercase in a TextBox

Hi All,

I remember that in C++ (MFC) you could specify whether the text box is a password and if you want to use uppercase/lowercase or as typed.

I see now you can still specify the password part but there is no way of changing what is being typed to uppercase ...

Is this true or am I missing something ... if not is the only way of fixing this by using an onchange event ?

You cannot change this for Web forms. This is not part of .Net or C# but from the HTML standards and you cannot change it :-(( You can however write some JavaScript that changes the text to upper when the user enters something in your text box

Pete2003,
Try this instead (use some delay to convert the typed text into uppercase):
function convertUpperCase(keyItem) {
setTimeout('ConvertKey("' +keyItem+ '")', 1);
}
function ConvertKey(selObj) {
document.getElementById(selObj).value = document.getElementById(selObj).value.toUpperCase();
}
</script>
<asp:textbox id="txtTest" runat="server"/>

txtTest.Attributes.Add("onKeyPress","convertUpperCase('txtTest')")'code-behind
