با سلام خدمت اساتید
در مورد ایجاد یک button در یک سلول دیتاگرید ویو در هنگام ویرایش هر کس کمک بنماید تشکر می کنم
نمونه سازی txt&btn را در یک مورد دیده ام ولی من فقط یک button میخوام در کنار تکست در حال ویرایش خود سلول داشته باشم اگر می شود نمونه کدی اینجا بگذارید سپاسگذارم
از مدیران بخش سی شارپ تقاضای همکاری دارم لطفا

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.
