CopyTo doesn't work with all rows

[Christopher]

I have a scenario on a form where I need to save all the rows in the form to a collection in memory to save any changes a user has made prior to saving them to a database, but still allow them to swap between different views.

I'm using the SelectionChanged event to handle storing the data, but I have found that calling GridView.Rows.CopyTo()  doesn't work.  I get a GridViewDataRowInfo[] array that is populated with null values.

Sample code is below:

_batchTrays = new Dictionary<int, GridViewDataRowInfo[]>();
int batchNumber = Convert.ToInt32(grid.CurrentRow.Cells["BatchNumber"].Value);
_batchTrays[batchNumber] =  new GridViewDataRowInfo[batchTraysGrid.Rows.Count];
                    batchTraysGrid.Rows.CopyTo(_batchTrays[batchNumber], 0);

this gives me an array populate with null values.

is there a preferred way to accomplish what I am trying to do?

Hello Christopher,

Thank you for the question.

I am afraid that I cannot understand your case in details. If you are using a RadGridView bound to a DataSet, it has a build-in support for the described scenario. All user changes affect only the DataSet that represents data in the memory. You could easily control when to send the changes to the database through the  DataAdapter.Update method.

If this is not suitable to your application, please, send me more details on it. If you could send me an example project it will be very helpful to investigate your case and provide you with further assistance.

I am looking forward to your reply.

Best wishes,
