In this thread, we are mainly discussing about "Add TabControl dynamically",as indicated by the first post and the title.
Since your new question"How to assign the image to a DataGrid from DataBase" is not directly related to the original issue, it would be best if you open up a new thread for the new question. In this way, our discussion here will not deviate too much from the original issue. This will make answer searching in the forum easier and be beneficial to other community members as well.
Thank you for your understanding.
