There are a couple of approaches that you can take in order to achieve the needed behavior.
You can create a custom Button Column that derives from the GridViewColumn class or you can edit the Cell Template of the GridViewColumn. Both scenarios are described in the following article from our documentation page - Add a Button Column. Please, review it and update me if it was helpful.
If you would like to add a button and on click to insert a new row in the RadGridView, I suggest you check the following article from our documentation page - Adding new entries. I have created a sample project for you to which you can refer and modify so that it reflects your scenario. Please, review it and update me if it suits your needs.
Thank for your answer, but it not exactli what i whant, the problem with this answer
that i have a lot of rows in my RadGridView, so i have a heigh to my RadGridView, and i have a Scroll viewr,
so i whant that the button should be at the end of the ragGridView, but into the scroll viewer!!! (i used the auto radGrigView scrol viewer).
Unfortunately, it is not possible to add such button within the ScrollViewer of the RadGridView. Adding one will interfere with the UI Virtualization of the control, which is vital for the overall performance. Another approach you could take is to use the GridViewNewRow functionality. Please, refer to the following article - Adding Rows.
