Hi Mr. Farshad
Thank you so much for your working,
But my main problem is multiple classes in one component. if you see UniXExtClasses.pas and UniXGridView.pas units (BufferedGrid component)
I've made lots of different classes like TExtObjectList, TXExtGridRowSelectionModel, TXExtGridCellSelectionModel., ....
I want to create these classes and save it in variables, and use them,
Please, If is possible convert this two unit (BufferedGrid components) and then i can be lean and convert other components,
Thanks for your help
Best Regards
