validation - Handling error messages using asp.net -
I have an asp.net page that contains a server side button and 2 text boxes which are only numeric values accept. Asp.net validation control.
If there are user types in non-numeric data in both text boxes, then how do I show only 1 error message on the page: "Only numeric values are allowed." And I want to get it without firing server side events.
Thank you.
OK, you will need to do this with javascript.
I know whether the input is numerical or not, I do not know the exact javascript methods, I think you can use a regex. But you have a hidden device like
& lt; Div id = "numericErrorMessage" class = "error" style = "display: none;" & Gt; Numeric value is only & lt; / Div & gt;
Then you can do this:
if (! Idar (text1) || ISNumber (text2) {document.getElementById (numericErrorMesage) . Style .display = 'block'; }
Of course this is "pseudocodish", but I think this will work for you once you can check for a valid number of javascript and just use that location in the nominal function Keep
