AJAX :: Update Panel: Need To Trigger A Partial Update For Any Event?

Mar 18, 2010

I am building a system for a school project. I currently have several Update Panels on the page that have many different controls on them. I also have a single Label control that i use to display messages to the user. I would like to have this label within an update panel also but there are literally hundreds of triggers that would require it to be updated and i dont want to type an absurd number of triggers for this one control.Is there a way for me to have this one panel update regardless of what happens?

How To Intercept Or Trigger Client-side Validation Before Ajax Request

Feb 3, 2010

I have a username textbox on a form, that has a few validation rules applied to it via the DataAnnotation attributes:

[Required(ErrorMessage = "FTP login is required")]
[StringLength(15, ErrorMessage = "Must be 15 characters or fewer")]
[RegularExpression(@"[a-zA-Z0-9]*", ErrorMessage = "Alpha-numeric characters only")]
public string FtpLogin { get; set; }

I also have a button next to this text box, that fires off a jQuery ajax request that checks for the existence of the username as follows:

<button onclick="check(this);return false;" id="FtpLoginCheck" name="FtpLoginCheck">Available?</button>

I'm looking for a way of tieing the two together, so that the client-side validation is performed before the call to the "check(this)" in the onclick event.

Edit: To be more clear, I need a way to inspect or trigger the client-side validation result of the textbox, when I click the unrelated button beside it.

Edit: I now have the button JS checking for $("form").validate().invalid, but not displaying the usual validation messages.

JavaScript - Can Wire Up Client Side That Would Fire Regardless Of The Update Panel

Jul 23, 2010

I have an asp.net page that is using and update panel and am including some javascript via a {script src=abc.js} tag. I have tried loading my javascript using both $(document).ready and $(window).load. Both fire on the initial load but fail to fire on an update panel postback.

Is there anything I can wire up client side that would fire regardless of the update panel? I know I can inject script server side but I ideally want to do this all client side and wire up what ever is needed the first time around.

Webforms - How To Trigger Client-side Validations Without Submit

Jan 17, 2011

I have a website in ASP.NET (WebForms, NOT MVC) which has a survey form divided in several slides. Each slide has a next button that, obviously does a transition (client-side, not post back or remote request) to the next slide.In each slide I have several ASP.NET controls with their related validators. I want this validators to be triggered when I click the next button (or maybe when each input loses focus?).

I remembered ASP.NET doing client side validation on lost focus, but maybe I'm wrong... (I quit doing ASP.NET development about 3 years now, so I can't remember)UPDATE: It would be better to make ASP.NET trigger each validator when the associated control lost focus. I remember ASP.NET doing this (or am I dreaming? =P)

Conditionally Trigger A Full Page Postback From A Link Button Inside Update Panel

Nov 29, 2010

How do I conditionally trigger a full page postback from a link button inside of an update panel?

I have a custom control that contains its own updatepanel with a link button nested inside of it. When the link button is pressed I want its event handler to have the option of either letting the control update as normal or doing a full postback on the page.

Here is the control hierarchy:

Page
Custom Control
UpdatePanel
LinkButton

Event handler Pseudo code:

LinkButton Click Handler Begin
If is a partial post back AND a full postback is needed
Page.DoFullPostback
End If
End Handler

Note: I aways need the partial postback to happen. I was considering injecting a __DoPostback in the controls markup but this seems hacky to me.
