I have a text box with a custom validator, compare field validator. I have a problem with the error message display.
my compare field validator works normally....ie; when I enter a wrong value it gives me the error message and when I correct it the error message disappears.but this does not happen with my custom validator......I do not undersatnd the reason..I tried to run an example downloaded from some site and that example works as required..I tried to implement a similar logic but still the error message does not disappear..
I'm working on an application form for a website which implements ASP.NET validation (including client side).
I have a requirement to display a message at the bottom of the page if the client validation fails. Something along the lines of "Please go back and check your answers".
The problem is, the submit button's OnClientClick event obviously fires before the client validation.
The validation summary is inside a div which I'd like to show as a modal message using the jQuery UI. The problem is that I can't figure out how to execute the javascript when the ValidationSummary is shown.
I'm using Data Annotations to validate my fields, Eventhough field is marked with Required Attribute the DropdownList/ListBox Value doesn't fire up to show they are required. how can I solve this.
Can the standard ASP.NET Visual Studio validation controls display an icon with a tool tip message instead of text, the way the WinForms ErrorProvider controls work? If not, is the AjaxToolkit's ValidatorCallout control the best approach? Is this control flakey?

I have a page that performs a long-running task (10 to 15 seconds) in the page_load method.
I have client-side javascript code that will display a decent "page loading" animated gif to the user.
I am able to invoke the JavaScript method from the code-behind, to display the "page loading" animated gif, however, the long-running task is hanging up the UI such that the animated gif doesn't actually display until after the long-running task is complete, which is the exact opposite of what I want.
To test this out, in my page_load method I make a call to the JavaScript method to display the animated gif. Then, I use Thread.Sleep(10000). What happens is that the animated gif doesn't display until after Thread.Sleep is complete.
