    By default, ASP.Net form submission will not pass back disabled field during postback.  To get around this, we can set the form property "submitdisabledcontrols" to true and it will pass back the value of a disabled field.  However I am having a problem with an Ajax postback as it does not contain the updated value of a disable field.

    For example, I have a disabled checkbox when the form load.  Through javascript, I enable the checkbox.  Then I fire an event that makes an Ajax call to lookup a value.  The Ajax call does a server side postback but the state of the checkbox is disabled.

    Please help.  Thanks.

    I was able to replicate without ajax as well. I am afraid that changes performed with javascript on the controls are always lost after postback and this sounds expected to me. I don't think the CheckBox is of the controls that persist their client state after postback.

    Just wanted to bump this one up and see if the Telerik developers had any thoughts on it. We have an app with checkboxes in a Telerik RadGrid and they are losing their values on Postback.

    Hi Jeff,

    Can you elaborate a bit on your scenario? Are you changing the checboxes atate manually? And is it lost after rebind or regualr postback?
