plugin creation

Hello ,

I have need to do some logic in the code when ever a datasource field draged to the band in the designer.
if there is en event that i can catch for it please let me now but i think not.

So I have been trying to make my own designer plugin tool window , i think there are events in there to do what i need.

I have manage to create the panel and add it to designer but i have find no example about how to add controls to that ToolWindowBase inherited class.

Basicly i wanted to add Label controld and some extra parameters attached to it and load them into ToolWindowBase inherited plugin and when ever drag and drop accours catch that control in the application main code.

if some one ask why i need this , the answer is,

I create dataset on my own and register it and then when ever a field in the datasource added to report in designer i would like to catch that moment in the code and use some logic couse i am preparing my query in the code. So far i couldn't find a way to it.

Thanks in advance
