Posted by: admin I have tested this and it works just fine. However, there are scenarios where we need to conditionally add (or skip) certain attributes as a whole.The perfect example of this is a TextBoxFor element which we would like to set readonly only in some circumstances. Just add disabled="disabled" as an attribute. Set the position to "relative". Readonly attribute prevents us to edit the value, but not the state. Contributing very very late…but anyway. If anyone else is using MVC and an editor template, this is how I control displaying a read only property (I use a custom attribute to get the value in the if statement). Sometimes we don’t want to make some form fields non-editable to users, like Product ID, Order Created Date, Post Author, etc. I have a group of checkboxes, and each has an onClick handler that submits the form (they’re used for changing filter settings for a table). anyway to do it? This presents a bit of a usability issue. e.g. This works because returning false from the click event stops the chain of execution continuing. The value of a disabled element will not be submitted to the server. HTML CheckBox is created by using tag, so its basic purpose is to gather input from the user. Note: A form will still submit an input field that is

The user could then hit the spacebar and check/uncheck the checkbox. However, my approach would be to use disabled (The user expects a disabled checkbox to not be editable, instead of using JS to make an enabled one not work), and add a form submit handler using javascript that enables checkboxes right before the form is submitted. You’ll still need some javascript to un-disable these when submitting the form. The above works for text and check boxes by setting any parent container as .readonly such as the following scenarios: I would have commented on ConroyP’s answer, but that requires 50 reputation which I don’t have.

The TextBoxes can be made ReadOnly by setting the HTML ReadOnly attribute using the HtmlAttributes parameter in Html.TextBox and Html.TextBoxFor helper functions. The checkboxes are in a span element with an ID of “filters” – the second part of the code is a jQuery statement that iterates through the checkboxes and disables each one. a JavaScript can remove the readonly value, and make the input field editable. If you want to have a read-only field that will represent the value you want to submit, use readonly text. To get around that would be to set the IsTabStop="False" also.
