Single Click Button with RequiredFieldValidators

[Mike]

Hi,

I'm using single click buttons.  What do I need to do for the client-side validators to fire before the button gets disabled?  The problem I'm having is my button is becoming disabled in the OnClientClicked, but my asp:RequiredFieldValidators are preventing the form from being submitted.  I only want the single click feature to kick in if all the client-side validation passes.

Thanks,
Mike

Hello Mike,

Here is the logic I use for my single-click buttons, which takes validation into consideration (when it exists):

function btnSingleClick_OnClientClicked(sender, args) {
    try {
        // determine if page is valid
        var pageIsValid;

        try {
            // get value from Page_IsValid
            // NOTE: Contained this assignment in try block in case Page_IsValid doesn't exist
            pageIsValid = Page_IsValid;
        } catch (e) { }

        // make sure page is valid or validation is null (doesn't exist)
        if (pageIsValid || pageIsValid == null) {
            // disable control
            sender.set_enabled(false);
        }
    } catch (e) {
    }
}

I hope that helps.

Hello Kevin,
 
In such scenarios you should ensure that the page validation is executed before the custom client-side scripts. This can be achieved by validating the aspx page on the client via the Page_ClientValidate method.
