Can we validate a control on a part of the page?

[Tea Maker]

Hello .Net Experts,

I am building an aspx page. Inside it, I have a Send Mail form, with controls: name, email and message and a "Send Mail" button.
On another area of the page, I have another button, when clicking it, a dynamic image will change (It's ajax based).

Now I have added a "RequiredFieldValidator" to the "Email TextField" , to make sure the email is entered by the user before he press on "Send Mail".

This is working amazingly, but the only problem is, if I don't want to send the email, instead, I would like to click the other button which change the image on the other side of the page, the image doesn't change, and I see the validator on the other side saying "Email Required!" .

I definitely understand that this is happening because I should place the email, but is it possible to make an area for the validation, where we can work normally outside it without validation?

Please suggest.

Best regards,
Wassim

Hi Wassim
You can use validationGroup Property of Validation Control for both controls like Email Address RequiredFieldValidator and The Send Mail button.

Say You have btnSendMail (SendEmail), btnSendImage(SendImage) and reqFldvalid(RequiredFieldValidator) email address (textbox).

1. Click the RequiredFieldValidator control and in the ValidationGroup property specify btnSendMail.
2. Click the btnSendMail control and in the ValidationGroup property specify btnSendMail.

Now run the page once you click the SendImage the validation won;t fire but once you click SendMail button you will see the error if the email address box is empty.

Hope this helps.
