Specified cast is not valid

[Guest]

I have a CheckedListBox control on a form. Whenever I want to check the item in the CheckedListBox with the following code, it give me an error message 'Specified cast is not valid'. why

chklstType.Items.Add("abc", True)

It works fine for me. Are you sure this is the line thats failing

Hi Chrysan,

As Jakob says, there is nothing wrong with your line. CheckedListBox.Items.Add uses objects, so it will accept anything you try to put into it.

The error message indicate that you have used a cast somewhere, and that this cast is not valid for that particular object.



Happy coding!

Your code should work.
