Validating checkbox asp net transexxual dating
Sometimes, when we build an input processing forms we might come across situations where we need to validate controls based on some conditions.For example, we can make a textbox to be required field only when a checkbox is checked or a dropdownlist value, etc.If you are too lazy or in too big a hurry to create your own validation control, you can quickly whiff up a validation scenario using an asp: Custom Validator.
So I will have to write custom j Query code for this in the View.
Include("~/Scripts/jquery.validate.unobtrusive.js")); In order to validate user’s skills so that he should select at least 3 skills (this is a collection property and not a simple one).
This Java Script looks like this: Please also note that since the Control To Validate property cannot be used on a Check Box List you need to hard-select the client ID of the Check Box List in the Java Script.
Is it a pretty common scenario to have a checkbox on a form, that is required to be checked during POST-ing of a form.
I found a 2001 article on how to do that (Building a Check Box List Validator Control) but it doesn't work properly on ASP. So I have to make some small changes to make it work on ASP. First thing you have create a class that inherits from Base Validator In this we check if the control is null and if the control can be cast to a Check Box List.
This is the methods that performs the server side validation in case Java Script is not enabled on the client, or not supported.In this method I just loop through all the items of the Check Box List and if I find one that is selected then I return true.Now we have the validation working on the server after a postback, but it would be nice if we could perform the validation directly on the client when the user toggles the state of the checkboxes.The key part here is Get Client Validation Rules method (adapter) where we define new, custom Validation Type called for the purpose of this post, as a 'brequired'.If you add a normal Required Field Validator and you want to validate a Check Box List, you will get a runtime exception informing you that the Check Box List cannot be validated.Simple solution to that would be to either change this code (which we really do not want to do) or create a new specific adapter.Tags: Adult Dating, affair dating, sex dating
