This is a very common exception in the Microsoft Ajax Library, and just means you've got something named wrong or you are missing a parameter. Sometimes you might just have the wrong element id set somewhere as a parameter, and this will throw the exception.

You'll need to post your code so we can see if there are any errors in your markup. The exception message itself is so generic it doesn't really tell us alot about what is going on.

Solution 1

Value of some of your element is null. You need to debug your code to find out which element value is null.

Better do a null check before doing any operation with the elements value.

Solution 2

it is looking like you are missing a parameter or may be the IDs of the controls (which you are using) is changing on run time, thats why these controls are not available on run time.

Microsoft JScript runtime error: Sys.ArgumentNullException: Value cannot be null.
Parameter name: element

The above statement says that in your code there is element(variable) which load with null value.

You can do one thing try to put your each and every variable in " Alert(); " and see what you are getting like this,

Suppose i have on evariable called, var example="This is an Example".
Alert(example);

It will give you output as "This is an Example."

I hope it will help you.

Solution 5

Set ScriptMode="Release" of your ScriptManager.

XML

<asp:ScriptManager ID="ScriptManager1" runat="server" ScriptMode="Release">
</asp:ScriptManager>
