Dataset Merge -> Index was out of Range

[Markus]

Hi

The exception below is thrown when I merge a dataset into an other. I use a
typed dataset with more than one table. If I catch the excpetion everyting
works fine (dataset is merged, rowstate is up to date and I'm able to access
the data), but this shouldn't be necessary.

After much debugging I found a better solution: Call BeginLoadData before
calling Merge on each table and after call EndLoadData - this works fine

I think, the reason is that I have an eventhandler for RowChanged on the
DataSet...

Microsoft, please fix this! Or is there an other reason for this misterious
behavior?


EXCEPETION:
Index was out of range. Must be non-negative and less than the size of the
collection.
Parameter name: index

Exception: System.ArgumentOutOfRangeException
Method: System.Object get_Item(Int32)

Hi Markus,

From the stack trace, I think that there might be something wrong with the
eventhandler of RowChanged event. Can you paste some of your code here?
