I have a ASP.Net Core MVC web application. I have a standard razor view which has a list of items with a delete button. What I want to do is if they user deletes an item from the grid go to the server calling an action which validates the item selected. IF invalid I want to return to the view and show a bootstrap modal explaining why the delete cannot be carried out. I call the delete routine using Controller / Action tag helpers and pass the unique Id to a controller event.
So basically if my delete validation fails show a modal dialog with a message. Any help please?
I ended up sorting this myself. Basically I set a viewbag property and give it a value of show. Then in my script section of my view I set the modal property to that viewbag.
I have a form where the user should be able to save even if there are validation errors.
These errors should be displayed once the user get into the form again.
So, i would like to invoke the validation of the entire form just after the form is displayed.
Currently, the validation is handled thru AJAX with several custom validators by using <f:validator/> and <p:ajax/> only when the user edits the field
Any suggestion is welcome!
Thanks!
An option would be to submit the form after it loads directly.
To achieve this you can use p:remoteCommand and something like jQuery('document').ready(function(){remoteCommandName()})
I get some error messages from the back end service and I want them to be displayed in the Validation Summary control on the page.
I am using MVC 3 and ValidationSummary is not on the page till a validation fails due to unobtrusive stuff i believe.
I looked at the following example but it does not work with MVC 3.
Does anyone knows how to simply insert an error message in Validation summary control in MVC 3 with all the unobtrusive stuff switched on?
Thanks,
Dexter
It sounds like this article on Remote Validation should do the trick.
Of course, you will still need to make sure you print the ValidationSummary in your views:
<%= Html.ValidationSummary("There are errors that must be fixed:")%>
I am trying to get validation to work for my very first ASP.NET MVC application. My problem is that all my controls were dynamically created. I have a Telerik tabstrip that has tabs that were dynamically (or programmatically) added. Each tab has a partial view with controls. The model that those controls map to is an Entity Framework model. I have decorated the model properties with annotations like “[Required]” (from System.ComponentModel.DataAnnotations;) and have added controls like Html.ValidationSummary and Html.ValidationMessageFor (for each field in your model) and I've been told it's supposed to work like magic! But it doesn't :(
Any ideas why my validation is not working? Do I have to do something special because the controls were created dynamically?

P.S. BTW, the server side validation works, but not the client side.
You need to store the datatypes and override the Validate() method on the Model. And verify casting works with the stored datatypes and the values of the dynamically created controls.. if the cast doesnt work return a validationresult.
I want to save html markup in my database for a field from an ASP.Net MVC2 application. Upon reading I found that using the [ValidateInput(false)] attribute lets you do that. But it is not working for me. The data comes from the extjs htmleditor form element.
Anyone has any ideas? Is there something else I need to do? Any setting in web.config?
