What version are you working with? Looks like the code you're talking about is working with v6 and v7 but v8 and higher. In v8, the syntax changed to customTableForm.SubmitButton.CssClass. There are versions out there for 6, 7, 8, and 8.1 (believe 8.1 will work with 8.2)

I'm working with V7 . You mean That the web part's code doesn't work with V7?

Hi Sonia, In Kentico v7 "customTableForm.BasicForm.SubmitButton.CssClass" is correct to set an CSS class to the submit button in the codebehind of your custom webpart code. So probably something else is going wrong. Do you have the possibility to debug the code. Probably the customTableForm is null.

From my experience this can occur in certain page lifecycle events like load / init. Can you try to move the code to the prerender event? Good luck!

Sonia, I created that webpart and it's on the Marketplace. Have you set the other properties of the webpart for instance the custom table you're choosing to edit? The CssClass property can be null or empty so as Maarten suggested, there is something else going on or another property that you haven't set which is causing a null object.
