hello!
i need help with this code.
so the problem is that i want to hide or remove the message of the custom validator when the required validator worked,so if you try this code you will see that when you type 3 characters in the textbox in the top ="txtUserName" and then move the mouse or "tab" to the second textbox ,then an autopostback happened so a message from the custom validator appeared ,so then delete these 3 characters and tab to the next textbox so you see my problem that the old message of the custom validator remain and the message of the required field validator appeared (*),so i tried everything i can and no success so i believe that if i can override the function of the required field validator that i add customvalidator1.text="" so i can success.
and this is the code:
and i tried enableviewstate=false for the customvalidator and no success no please i need your experiences and help.
so if you sign up in a new hotmail account then in the field "hotmail account" at the top is what i need for example type a wrong hotmail or existing for example "d" ,then tab to the next textbox so i message will appear,then clear the first textbox and tab again to the other so another message appear.
so i need your help and i prefer an example for resolving my problem.
thank you very much
