GridView exception on pasting from excel

[Alexander]

Hi, guys.

I have a big problem with pasting data in to the grid.
I have a grid in my app with 5 rows for example. When i'm trying to paste more than 5 rows, I expect the new rows in the grid to appear.
But I get just an exception: "Cell is already in the collection" Parameter name: cellInfo

You can find the sample project here
Thanks.

It's in the GridDataContro.PerformPaste method.
Looks like the problem is here:
IEnumerable<GridViewCellInfo> items = this.InsertFromClipboardValuesCollection(values, upperLeftCellLocation, rightBoundary);

Any update on this?

Hi,

 Can you post more info about your grid version? I've checked your account however you do not have any downloads.

Hi, Vlad.
Thanks for answering. It's Q2 2011.

Hello Alexander,

 We have isolated the issue and we currently working on a fix. For the time being you could try setting IsSynchronizedWithCurrentItem of RadGridView to false - this should take care of the problem. 

I have updated your Telerik points.

I'm using the latest build: 2011.2.0912.4 (WPF).  I was having the same issue and now its fixed; partially.  I have a question on what gets kept in the Clipboard after a paste.  For instance, if I copy two rows from my grid and then select the last row and paste, I get what I expect (the first row copies over the last row and a new row is inserted with the values of the seconded copied row).  If I select and copy another two rows and do a paste, if you look at the clipboard (by stopping in the RadGrid's Pasting event), the contents will contain the rows I just copied and the row I previously pasted over.  Doing a paste will now paste 3 rows.  Continuing down this path gets worse and the grid starts to get confused.

A work around, at least for my application, was to capture the number of rows selected in the Copying event.  And in the Copied event, strip out the count of those items from the Clipboard, clear the Clipboard and then replace the selected content.

Additional info...After pasting at the bottom of the grid...the visually selected row is the last added row.  However, the previously selected cell/row is still selected where the paste began.  This causes issues if you try to paste multiple times in a row.

Hi Darrick,

Thank you for reporting these issues.
We succeeded to reproduce the first problem. We will address it in the future Internal Builds.

As for the second problem could you please give some more information or modify the attached project in order to reproduce it? In case you want to send the project back you have to open a new support ticket.

I have updated your telerik points accordingly.

Kind regards,
Vera
