Creating Custom DataGrid Control

Question

Hi,
I have created a Class library project which binds different controls to the datagrid columns means i created different columnstyles.. i added that dll into my device application and its working absolutely fine..
Now i want to impliment this feature in a custom datagrid control in its design time.means during the design time itself the developer should be able to choose between different column styles(Like DataGridTextBoxColumn). Am very much new in this field .. if anybody knows pls tell me how i ll  add the field in the design time.. if anybody hav any sample pls mail me at [email protected]
