Hi Prof.

Lately I am working a project and I have a DataGridView that bind to a dataset in this way :

C#

ComponentsGvwDataset = new DataSet();
            da.Fill(ComponentsGvwDataset, "dtcomponents");
            ComponentsGvwChanges = new DataTable();
            ComponentsGvwChanges = ComponentsGvwDataset.Tables[0];
            this.GvwSearchGrid.DataSource = ComponentsGvwChanges;

, I need to get the changes in the data table once I finished changes any cells value with no need to go down one row to commit the changes in the DataGridView back into the data table, I tried many options with no luck, and any hint or help will highly appreciate.

Thanks in advance

WPF or WinForms? There is also something called accept changes in a table...

thanks Kenneth , I tried accept changes ,but it doesn’t work , the Get changes() works with me when i change cell value and move down to a different row ,what I need is getting the changes immediately after Cell End Edit to do furthered checks.

Is it WPF or WinForms? Sounds like WPF but.... and add the tag too :)

If I am understanding you correctly then the issue is that you cannot raise an event without exiting the cell.

There is a "CellValueChanged" event that is raised after you finish editing a cell (ie by pressing tab or enter or clicking off the cell etc).

In fact, if you create a separate thread to watch the cell value it does not know anything has changed until after you have left the cell in question.

So basically you are stuck having to leave the cell to get any updates.

IF you do not want to go down a row (ie continue editting different fields of the same row) but also send the latest data then you can attach to the CellEndEdit event and make the update manually. If this is the case then check out this MSDN entry
