Info

Atlas Controls ❑ ❑ regexValidator — Verifies the data against the supplied regular expression customValidator — Defines a custom expression handler Validators are defined together through a collection and are typically fired on a propertyChanged event. During this event, the validation is checked, and the validate event is raised. From there, code can subscribe to a validation event. This event is raised after validation. During the validation, the validators are checked. Checking the validators may result in the client-side control invalid and validationMessage properties being set. In addition to validators, a special control exists for displaying this information. This control is of type validationErrorLabel and is used to display error messages — similar in function to the ASP.NET ValidationSummary control. The error messages may be displayed through an asterisk, tooltip, or other mechanism. In addition, validators may be grouped together. A rollup of the validator controls can then occur. Try It Out Using a requiredFieldValidator In the following code, you are going to investigate the use of the requiredFieldValidator. The textbox requires data entry. A requiredFieldValidator is attached. Enter a text field, then remove to see the effect. The validator is shown via the tooltip. * How It Works Now look at the steps taken to get this code to work. 1. An HTML textbox and span are defined along with the Atlas ScriptManager. 2. Within the xml-script section, there is a set of defined components. The textBox is defined, and a validator is assigned to the textBox control. 301
Chapter 11 3. The validationErrorLabel is set up with a targetElement and the associatedControl. Figure 11-5 shows the output of the preceding required field validator. Figure 11-5 Try It Out Adding Datatype and Range Validation Support The next step in this example adds datatype and range validation support. By making the changes that follow to the xml-script section, the validation is added. In this example, the tag contains a tag. Within the tag, there are several validators that are set up. The first validator is the requiredFieldValdiator. The requiredFieldValidator requires that a value be entered for that field. The second validator is the typeValidator. The typeValidator sets the type that must be entered. In this example, the Number type must be entered. The third validator in this example is the rangeValidator. In this example, if a number outside of the range from 10 to 20 is entered, a message is presented to the user regarding the number being out of the specified range. 302
