ASP.net Client Side Validator problem

John_Mc

Hi,

I have a Modal Popup displaying properties that can be edited by the user. My problem is that if a user triggers error validation and clicks the close button, when they open a different property then the OK button is disabled because of the previous validation error.

E.g

1)User clicks 'Cost' and a Modal Popup displays the Cost properties.

2)User enters invalid Data. Validation message is shown. User clicks Modal Popup Close Button.

3)User now clicks 'Date' and a Modal Popup displays the Date properties. Everything appears normal - no validation message is shown.

4)User tries to click OK button but nothing happens.

This only happens when validation has previously been triggered. The properties themselves are added dynamically to a placeholder. The very first thing I do is clear that placeholder of any controls - so this should clear the validator as well shouldnt it?

Would appreciate any suggestions!

Thanks
John

The validator objects are held against the page. Once one of the is marked as invalid, it will stay that way if you cancel the modal dialog. There's a couple of ways you can try clear this out.

I think calling this.Validate() forces every validator on the page to revalidate. I'm not sure how this would work with dynamic controls that no longer exist.

You could iterate through this.Validators and set each isValid = true. This will of course revalidate any other controls on your page which should be invalidated.

You could try to find the specific validators with this.GetValidators and set isValid = true, you may need to create the validators specifically as part of a group to find the correct ones.


edit: Oh, and if you already have a reference to the validator then just set it's isValid = true.

Would splitting them into validation groups not work?

Hi Steven,

Thanks for your reply. My problem is that all of this is taking place on the client side, so I have no server side events to iterate through the controls....

No because all of them are based on a Modal Popup Base class so use the same OK & Cancel buttons.

It's a very messy problem

There is the ValidatorEnable javascript method for asp.net controls, it allows you to enable and disable on the clientside as you go. Perhaps you could use that?

Thanks for the suggestion Phil, however I got around the problem by removing the invalid text from the textbox in a server side event. Then I just hid the modal popup.
