Solution 2

In the function which shows up the "Loading Icon", check if the page is valid:

C#

function showLoadingIcon() {
if(Page_ClientValidate())
{
//show loading icon
}
else
{
//hide loading icon
}
}

PS: Since you need to validate only the RequiredFieldValidators - use group name for all of them and validate the page as below:

C#

if(Page_ClientValidate("GroupName")){
//Code Here
}

Hi Jyoth.

thank you for your suggestion. I am using that one now but i came accross something.
is it possible to turn-off the auto validation to my controls? instead i will do manual validation by executing Page_ClientValidate()? because what happen now is that the validation is being executed twice.

I have accepted the solution. I just disable the messagebox property of my summary validation to prevent displaying of error message twice.
