I'm using c#.
I define a field named nData, and a property named Data like this:
in the Form_Load function:
but the second line of the Form_Load code snippet throws an InvalidCastException, and says "Specified cast is not valid". if i change the third parameter of the second line to "Data", I still get the same error. so, my question is, is it possible to use AddChildItemBinded in C#? If it's possible, any sample available? thanks. |

Hi,
Just tried with vc2002 and vc2008 - your code works.
Can you modify our sample and attach it here.

you can get my project here:
http://python.leojay.googlepages.com/pgtest.zip it's strange that, in your PropertyGrid sample, my code works. but in a new project, it doesn't. i don't know why. :( |

Hi,
Change this:
Properties->Application-> Assembly Information:
Click Checkbox "Make assembly COM-Visible"
and instead of "nData" specify public "Data"

thanks, that works.
is it possible to add some specific description in the thrown exception? "Specified cast is not valid" is really not a good hint. |
