pages clientIDMode="Static" ArgumentException

[Chris Marisic]

I have a page with a RadScriptManager & RadStyleSheetManager and a few RadGrids (no ajax manager) when I set

<pages clientIDMode="Static">

In the web.config when I run my page I encounter this error

Value cannot be null or empty.
Parameter name: elementID

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1

I don't even have a radajaxmanager on the page. This error is very confusing.

If I change the clientID mode back to either AutoID for the 3.5 and earlier standard or predictable this error goes away. I'd like to use static naming though.

Hi Chris,

I just posted a sticky note about this problem in the RadControls for ASP.NET AJAX forums. You can found information about how to fix the bug at ClientIdMode support for ASP.NET 4.0.

What control would I want to set specifically to use AutoID? Would that be the scriptmanager?

Hi Chris,

You should set the ClientIDMode property to AutoID directly in the RadGrid control declaration.
If you still experience the problem set the ClientIDMode attribute to AutoID in the @Page directive.
