EntityPagedCollectionView Refresh

 

Well, I applied the updated and did some testing, and it seems to work but only part of the time.  Most of the time, it moves the current item to the first item on the list. 

 

The only thing I was able to come up with is that it seems to move the CurrentItem at the start of the refresh, not the end when the new items arrive. 

 

So what happens visually is that an item in the list is selected, I click on the refresh button, the first item on the list is selected.  Then, if I move it to a lower item while the refresh is in progress, it stays there, even after new items show up in the list.

 

If there are no new items, it still moves it to the first item on the list 9 times out of 10.  I don't know what the difference is on the 10th one.  If I can figure it out, I will post it here.

 

Note that I have also tried RefreshCurrentPage() instead of Refresh(), but no new items show up using the former.

I know exactly what the issue is now: You are correct in your testing. However, if you subscribe to CurrentChanged, it fires three times after a refresh. The values of current item goes to -1, then -1 again, and then finally goes back to the correct item. So in my project, the -1 was forcing the current item to the first item in the list. The workaround is to ignore a negative value.

I have a sample that shows this which I will email to Kim (I don't see how to upload on this forum).  In the sample, just select any item in the grid, then click refresh the fresh button at the top. At the bottom is a console window that shows the Current Position changing as described above.

The issue seemed to be with the DevForce MVP group.

It appears to be fixed now.

 

Can you double check it and confirm?

 

Thanks.
