Last Row deleting problem

[Josh]

Hi support,

I am attempting to institute a radgrid using a user control insert/edit form.  I am running into a problem with deletion of the last row in the grid on the last page.  For example, I have a situation where there are 4 records in the grid with a pagesize of 3. If I delete the 4th record then after the successful deletion, the paging is thrown out of whack and the grid can no longer find any records within the grid.  Moreover, the grid will not rebind either.  As I have a dropdown that controls the grid datasource which generally allows a different search. 

Note, since I have the paging as "always visible" the pager at the bottom is clickable and if I click the page number at the bottom it will reorient the grid and put everything into the right place.  I have tried a number of things and don't know where to go.
Without this always visible on, it is totally broken.

Bump!  I haven't heard any response from anyone on this.

Is this a bug?

Hello Josh,

I suggest that you check whether the deleted row is the only one on the page and resetting the CurrentPageIndex in this case.
Please give it a try and tell me how it goes.

Mira,

I haven't been ignoring you.  I had attempted something like this already, but I've been distracted with other things.  I'll let you know when I try it.

Mira,

Thank you.  I had tried to put in place your solution before with the following code:

        if (e.Item.OwnerTableView.Items.Count == 1)
        {
            e.Item.OwnerTableView.CurrentPageIndex = 1;
        }

However, this didn't work.  Then it occured to me that the PageIndex could possibly be zero based and it was!
The below code worked for me.  Thanks for your help.

        if (e.Item.OwnerTableView.Items.Count == 1)
        {
            e.Item.OwnerTableView.CurrentPageIndex = 0;
        }

i almost have the same problem,

i have a user control that acts as a command panel, when deleting the last row (even that there are many other row - one page only), some of the controls inside that user control are not created correctly.

what can i do in my case? it is not the lastest :) row, but the last row.
