ببینید یک نمونه قبلا داشتم ولی من فقط هنگام ویرایش میخوام ایجاد بشود و TEXTBOX هم کنار آن ایجاد نکنم
I have another way to do this, we can take the following steps:
1). Make a usercontrol to host a textbox and a button, as shown in my following sample, the
TextAndButtonControl class which inherited from usercontrol.
2). Create a TextAndButtonControl instance(NOTICE: we just need one), add it into the control
collection of the DataGridView, initially make it invisible.
3). Handle the DataGridView.CellPainting event to draw a textbox and button style on the cell,
which make the cell looked like some kind hosting a usercontrol in it.
4). Handle the DataGridView.CellBeginEdit event to show the usercontrol right in the cell while
editing, you can edit in the textbox in the usercontrol and click the button, write your logic in
the Click event of the button, I just show a message box for example in this sample.
5). Handle the DataGridView.CellEndEdit event to update the cell value.
6). Handle the DataGridView.Scroll event to reset the location and size of the usercontrol while
scrolling. Without handling this, the usercontrol would stay still while scrolling.
That's all. I write a sample for your information. Enjoy taking it.
Any question about this please no hesitate to let me know.
Best Regards.
