[Solved] The relationship between filters and pages.

[Roman]

This is kind of funny because any single example I have seen on your site and any others RadGrid  I used it was working but in one my case flipping pages kills the filters. It looks like nothing has to be done to preserve filters when pages changes, so I wonder why it does not work with my particular grid.

It is 2009, Q1 Radgrid, with standard NextPrevNumericAndAdvanced mode paging. It fed by non-cashable DataReader. The grid does NOT use Ajax and each repost sucks fresh data.

The filtering works fine, so the paging. However, the PageIndexChanged even does not fire. I thought to run in PageIndexChanged event across the columns, cash the CurrentFilterValues and then reset the Values in PreRender event but no luck for now. What is particularly interesting is that in your demo Grids you do NOT it and your filters/pages work very consistency with no extra coding efforts.  Am I missing anything?

Rgs, Romy

Pavlina, thanks.

I have no problem with use the grid and the filters/pages synchronization works fine with many others my RadGrids. Ny concern was about the behavior of the specific grid.

After much agony I have discovered what was the problem and I am posting is here just in case other would come across the same. It looks like the filters/pages synchronization gets wiped out as the PageIndexChanged event does not fire what the grid enables SEOPaging. I was under impression that SEOPaging juts publishes the QS and does not demand you to write own QS logic.

Anyhow, killing the SEOPaging brings the filters and pages back to bussness.

Thanks, Romy
