Edit Cell in DataGridView (VB.Net). I'm trying to edit a datagridview that's populated by a SQL database. You would still need to update this change to your. I have to edit a cell in a datagridview(in each row of the view). Update these values and display the new updated values. I could change the underlying datatable values but I don't want to do that if there is a way around it.
All. I've been googling this question for an hour now and still can't understand how it works. I have DataGridView control on my form, which has 3 columns + 1 ButtonColumn, to which I add lines like this:
The text for the button is set like this:
Now, I want to change specific button's text, once user clicked on it, to, let's say 'Done'. I tried it like this:
And it doesn't work. I've tried a few answers to a similar questions here, on stackoverflow, but it doesn't work as well. Forgive me if I overlooked something. Would anyone be so kind to explain me how to do this, and why doesn't this work?
UPDATE:
UPDATE2:
I can't even change the Value manually in debugger, it's immediately set back to the old value.The problem seems to be sepcific to the DataGridViewButtonCell, because cells of other types change fine.

Black knights tango. You need to change from using cell.Value to
Changing cells value only changes if you add that cell back to the datagridview.This way you can get rid of using the cell like this.
I edited out the rest as I don't believe it is needed for what you are doing.
This is only when you use a firewire card providing power for accessories that need their power supply from the 'puter. Canon xh a1 camera storage driver. I've got a HP firewire card without the power connector. Vegas can see and play the camera's tape player in DV only. Very little chance of blowing the port that way.

When it's set, it's not possible to edit ButtonCell's value.Any readonly option of the DataGridView is irrelevant here, they specify if the user, not you, can edit cells.

I have a dataGridView and a button on a form. When I do any editing, insertion or deletion in the dataGridView1, the code below does the magic
I have the same kind of project at home, I do not have the source code with me but if needed I can check somewhere this weekend to see what exactly I have done, but I believe it's some of the following:
Since you are using a dataset and a dataadapter this can be achieved very easily.
As long as your DataGridView1 has the properties enabled for users to add/delete/edit rows you could use the following code.
The DataAdapter.Update() Method will auto generate any insert/update/delete commands needed to update the results of your fill query compared with the current data in your datagridview.
You can set those commands (properties) as well in case you prefer to modify them, though this is not necessary.

This only works ofcourse after a user has made changes to the DataGridView. Add this code to a simple button and see if you have any luck. It definitly was something this simple :)
I have implemented a solution that inserts/updates/deletes data in MS SQL database directly from DataGridView.To accomplish this I have used the following events: RowValidating and UserDeletingRow.
It is supposed that you have
declared and initialized.Here is the code:
Hope this helps.
