Solution 1

Yes you can. Try something like this if I am getting you right:

C#

if(dropDownList1.SelectedIndex == 1)
{
  //call function say characterValidation();
}
else if(dropDownList1.SelectedIndex == 2)
   {
      //call function say numericValidation();
   }

and so on.

Glad it works.
Do you really have 10 text box with respective 10 validations??

If so, use switch.

darshith 13-Sep-12 7:15am

My bad. Just a moment.

darshith 13-Sep-12 7:25am

client_1: (textbox1)..... should accept only numbers
2: (textbox1)..... should accept only variables
3:(textbox1)..... should accept only email
4:(textbox1)..... should accept only maxlength(4)
5:(textbox1)..... should accept only preceedingzeros........like wise......

I think if else ladder make you work out, if it is up to 5 or 6 validations of text box.

Hi,

ofcourse it is possible. You can use Custom Validator. this will accept the javascript function as validation function and based on the validation you have to set IsValid to True or False.

try like this,

JavaScript

function fnValidate(sender,args)
{
  var ddl = document.getElementById("dropdownList1");
  
 if(ddl.options.value == "client1")
 {
   var txt = document.getElementById("Textbox1");
   //validate text box
   
   args.IsValid=true; //based on the validation set the true or false.
 }
 elseif(ddl.options.value == "client2")
 {
   var txt = document.getElementById("Textbox1");
   //validate text box
   
   args.IsValid=true; //based on the validation set the true or false.
 }
return;
}

check this[^] for more on Custom validators. Set the ClientValidationFunction to above javascript function.

hope it helps.
