Hi,
I have a solution to your problem but little bit of _javascript_ you have to
use not for validating the control but to enable or disable the validation
control as per requirement.
Do the Following steps to achieve the solution
1)Initial requirement
a.Three Server side Textbox (txtSearch, txtUserName, txtPassword)
b.Three Server side Required field validator each for the Textbox and
set the Enabled Property
to False.
c.Two buttons one for submiting the user name and Password and other for
search textbox.
2) Assign the control to validate attribute of each required field
validator for the required textbox.
3) Create two _javascript_ function
a.EnableUserName_Password()
b.EnableSearch()
4) In the EnableUserName_Password() function enable the Required field
validator for User Name and Password
5) In the EnableSearch () function enable the Required field validator
Search
6) Attached the EnableUserName_Password() to the Submit button through code
behind
(for e.g.;
btnSubmit.Attributes.Add("onclick","EnableUserName_Password();");)
7) Attached the EnableSearch () to the Search button through code behind
(for e.g.; btnSearch.Attributes.Add("onclick"," EnableSearch();");)
The Code is pasted here
