Sporadic error using rad button

The way the button is setup, is that there are a couple of rad buttons inside a rad tree list, of which is in a user control, and the usercontrol is inside a rad wizard, and finally the rad wizard is inside an rad ajax panel. I tested the wizard with the buttons locally on my machine and pushed it online and I have no issues. However, I am getting error emails that it seems to be throwing an error on the rad button, with a couple of other users. So far I only received two of the errors in the control. So I am unsure as to why it would be throwing an error. Would any one know why it worked for me but it threw these errors on a couple of users?

Here are a couple of the stack trace errors:

System.ArgumentException: Invalid object passed in, ':' or '}' expected. (181): {"text":"Add","value":"","checked":false,"target":"","navigateUrl":"","commandName":"AddTag","commandArgument":"","autoPostBack":true,"selectedToggleStateIndex":0,"validationGroup"% at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeDictionary(Int32 depth) at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth) at System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(String input, Int32 depthLimit, JavaScriptSerializer serializer) at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize(JavaScriptSerializer serializer, String input, Type type, Int32 depthLimit) at Telerik.Web.UI.RadButton.LoadPostData(String postDataKey, NameValueCollection postCollection) at System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Here's another one :

System.ArgumentException: Unterminated string passed in. (29): {"text":"Add","value":"","che at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeString() at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeMemberName() at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeDictionary(Int32 depth) at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth) at System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(String input, Int32 depthLimit, JavaScriptSerializer serializer) at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize(JavaScriptSerializer serializer, String input, Type type, Int32 depthLimit) at Telerik.Web.UI.RadButton.LoadPostData(String postDataKey, NameValueCollection postCollection) at System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

RadFilter Text Field Editor validation

I am dynamically adding RadFilter editors, such as RadFilterTextFieldEditor, to RadFilter, server side.

When the web page is running, if a user enters certain "dangerous" text strings such as "<!--" or "<script>" into the RadFilterTextFieldEditor, the RadFilter control stops functioning (you can no longer add new expressions or groups to your Filter expression). If I try to navigate to another page in my web app, I get logged out because my session has been destroyed/lost. There MAY be an unhandled "A potentially dangerous Request.Form value was detected" exception that is causing the user session to be destroyed.

My fix would be to intercept the RadFilterTextFieldEditor text and strip any potentially dangerous user input (such as embedded JavaScript).

I do not see an OnBlur/OnChange event on the RadFilterTextFieldEditor that I could use to intercept the user input before it is posted.

I tried adding an asp.net validator on the RadFilter control but that does not work because RadFilter is not an "input" type of control.

I looked at the RadFilter client side events (OnFilterCreated/OnFilterCreating) but those do not appear to allow me to strip the user text input before it is too late.

Can you suggest a way to handle RadFilterTextFieldEditor text to prevent users from entering "dangerous" text.

Cannot read property 'parentNode' of null

Hello,

The project that i'm working on uses Telerik version 2013.3.1324.40 and recently the following error happened in our client (see attached image for more details):

Uncaught TypeError: Cannot read property 'parentNode' of null at Object._endRequest (Telerik.Web.UI.WebRe...e41%3ae4f8f289:6089)

When analyzing the JS line in which the problem occurred we realized that it is related to the panels that Ajax uses to update the page objects (in this case, the absence of them).

However, so far we have not been able to simulate the situation and the customer himself confirmed that the error is irregular and after the error happens they reenter the page and do the same action and it works just fine.

If possible, we would be grateful if you could guide us to what may be causing the error in order to correct it.

Note: I apologize for any grammatical errors as english is not my first language.

Best regards,
