ASPxClientEdit.GetIsValid Method

Gets a value that indicates whether the editor’s value passes validation.

Declaration

GetIsValid(): boolean

Returns

Type	Description
boolean	true if the editor’s value passes validation; otherwise, false.

Example

The code sample below implements custom validation without using any predefined validation capabilities. Note that you should set the ValidationSettings.EnableCustomValidation property to true to show an error frame.

JS

function OnAgeValidation(s, e) {
     var age = tbAge.GetText();
     if (age == null || age == "")
          return;
     var digits = "0123456789";
     for (var i = 0; i < age.length; i++) {
          if (digits.indexOf(age.charAt(i)) == -1) {
               tbAge.SetIsValid(false);
               break;
          }
     }
     if (tbAge.GetIsValid() && age.charAt(0) == '0') {
          age = age.replace(/^0+/, "");
          if (age.length == 0)
               age = "0";
          tbAge.SetText(age);

     }
     if (age < 18) {
          tbAge.SetIsValid(false);
          tbAge.SetErrorText('Age must be greater than or equal 18');
     }
}
