How to achive validation while typing

[ManniAT]

Hi,

I want to use RadTextbox to achieve the following solution:
http://www.pp-p.net (Type OK into the textbox)

My Problem(s) - I can't find an event for KeyUp - I found this post:
http://www.telerik.com/community/forums/aspnet-ajax/input/showing-error-style-programmatically.aspx
But when I hover the control or type focus it - the error display disappears.
I guess there are some styles :focus or other like this -- BUT it is hard to figure this out - and you (I'm sure) know which styles are involved.

I further guess there is a script which changes the class .riError to riFocus or some kind of .riHover - can this script be disabled?

Or is the solution so much effort that it is better to do it "my way" by using a hidden RadInput (to get the styles) and use a default input?

Regards

Hi there,

I managed it.
It just was a bit confusing where and when styles get changed.
Finally I managed to solve the problem.
What I got is a RadTextBox which validates while typing.
I solved it within a WebUserControl. All properties of the RadInput used are (can be) inherited and passed to the contained control.
So skinning and other features are still available. :)

The sample at http://www.pp-p.net/Default.aspx shows two of those controls.
The definition is simple:

<uc1:WSTextBox WSMethod="CheckVal2" runat="server" /><br />
<br />
<uc1:WSTextBox SupressSubmitIfInvalid="true" WSMethod="CheckVal3" runat="server" /><br />

Notice the SupressSubmitIfInvalid - this parameter decides if the "optical validation" works as "normal validation" which means that submits are suppressed while the control is in invalid state.
Validation is done with a webmethod - which returns "-1" error - "0" empty and "1" OK.
The User of the control provides the method and tells the control the name of it via WSMethod="xxx".

In the sample the two methods look like this (just a stupid example):

[WebMethod]
public static string CheckVal2(string strIn) {
    if (string.IsNullOrEmpty(strIn)) {
        return ("0");
    }
    if (strIn.Length < 3) {
        return ("-1");
    }
    if (strIn.StartsWith("X")) {
        return ("1");
    }
    return ("-1");
}
[WebMethod]
public static string CheckVal3(string strIn) {
    if (string.IsNullOrEmpty(strIn)) {
        return ("0");
    }
    if (strIn.Length < 2) {
        return ("-1");
    }
    if (strIn.StartsWith("Y")) {
        return ("1");
    }
    return ("-1");
}

If someone is interested (just reply here) I can post a Code Library project about this usercontrol.

Regards and sorry for the "unneeded help thread" here
