Question

How do I call ASP.NET Page Validators manually on the client-side?

Asked by: cylikon

If my users clicks on a button the page and a certain value is selected in a dropdown list I need to test only one of the validate controls on the page. To do this I put an OnClientClick element pointing to a Javascript function.  In that function I have written the code to test for the deciding value.  No I need this...

if (true)
{
//fire just one specific validator
}
else
{
//fire all validators
}

I know I need to loop through the Page_Validators array.  What do I need to do in that array?

well, this isn't exactly what you want, but if you don't mind a server round trip, you could just turn off client side validation.  Then you could code whatever you want on the backend to check your validators to see if they're valid depending on what's in the list box.  The property on each validator has to be set to false. EnableClientScript

Each validator also has a client side api you can enable or disable them, which is more of what you want,but i'm not as familiar with it as i just do what i suggest above when i need to.  Here's an article on it though if you want to try the client side stuff still.

I ended up making each validator a custom validator and having my conditional in each function.

Kluggy hack but it works.
