You’ll need to check args.get_postBackElement().id in your InitializeRequest handler and only trigger that indicator when it’s Username (or whatever your username field’s ID is).

I am trying to use this in a DetailsView. When I click my save button (Insert command) the javascript function InitializeRequest fires again causing the “Checking availability…” to show again in my again(already been verified). Trying to figure out why the (CommandName= Insert) is causing the InitializeRequest to happen again. This is probably really evident but been working hard and in a brain frazzle, I appreciate your help.

You’ll need to pay extra attention to your ClientIDs in a master page scenario. Take a look at this post and its comments, for some ideas: http://encosia.com/2007/08/08/robust-aspnet-control-referencing-in-javascript/

Dear Dave,

First checked your code stand-alone… But when I implemented it in a converted createuserwizard, it failed on the JScript…

CreateUser changes the IDs of the DIVs, so I went to the compiled code, found the changed IDs, and changed the JScript refs to them – for UserAvail and the Button…

Hope this will help others…

Perfect. Exactly what I was looking for. Looks like there’s one extra angle bracket in the aspx file, right above the update panel. seems to be causing this issue when you fire a build.

Error 1 Content (’< ') does not match any properties within a ‘System.Web.UI.UpdatePanel’, make sure it is well-formed. C:\Users\admin\Desktop\AJAXUsernameCheck\Default.aspx 24

Removed it and it worked perfectly. You might want to change that in the uploaded zip.

Thanks for putting this out.

Oops, nevermind – I feel a little blind. I didn’t catch that that’s a piece of Javascript.

Hi,
This is a really interesting tutorial, but I’m wondering – how would I do this using Visual Basic, instead of C#?

I’m not quite sure exactly what you’re asking. Could you email me some code (or post it here, using

 tags)?

I am having trouble adapting the code to work within a templated create new user wizard. I keep getting the error Error ‘UserAvailability’ is not declared. A command like (CType(CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl(“cboCountry”), DropDownList)).SelectedValue is not working either. Any help would be appreciated.

I think you may be right about that. I’ll give some thought to rewriting that to work within the framework of a custom validator.

Thanks for the suggestion.

Smart stuff, but don’t you think a (custom) validator would be the way to go here? Although, the current validators don’t always work correctly in an UpdatePanel.
