Solution 3

You can do the uppercase part very simply by using CSS:

HTML

<input id="myInput" style="text-transform: uppercase" type="text" />

The non-numeric as well needs a little more complexity:

HTML

<script language="JavaScript">
  function noNumerics(evt)
    {
    var e = event || evt;
    var charCode = e.which || e.keyCode;
    if ((charCode >= 48) && (charCode <= 57))
       return false;
    return true;
    }
</script>
....
<input id="yourid" style="text-transform: uppercase" type="text" onkeypress="return noNumerics();"/>

in asp.net c# this code is not working.
onkeypress is not available.

please help me.

Look at the code above: See the bit which starts
script language="JavaScript"
That should be a clue where it goes...

Solution 5

it will help to accept non numerical with uppercase.

<asp:TextBox ID="textbox1" runat="server" text-transform: uppercase" onkeypress="return noNumerics(event);" >

function noNumerics(evt) {
evt = (evt) ? evt : window.event;
var charCode = (evt.which) ? evt.which : evt.keyCode;
if ((charCode >= 48) && (charCode <= 57)) {
return false;
}
return true;
}

This adds nothing to the solutions that were posted well over 2 years ago. Avoid answering old posts that already have adequate answers unless you have something really new to bring to the discussion

its an improved one on textbox onkeypress"return noNumerics(event);" is added here .. it will work check again CHill60

If you want to reply to a post you need to use the "Reply" link so that the poster knows you have responded.
I don't see it as a improvement at all - it's essentially identical to Solution 3 (posted over 2 years ago), just using the conditional operator ?: instead of conditional-OR ||
(Given that you have received 2 downvotes already then I'm not the only one with this opinion)

yes you are right. i found that it was upped on the page, but not "under the covers". so i do like this

string vclsr =((TextBox)gvdata.Rows[i].FindControl("textbox1")).Text.ToUpper();

the last .ToUpper(); is use to save in uppercase.
i think this time it will work. it work for mine

Solution 4

You can simply use style="text-transform:uppercase" in your textbox declaration.

Example :

<asp:TextBox style="text-transform:uppercase" runat="server" ID="myTextBox" />
