Hi,
I have a situation where 52 columns are required. (week/year)
If I use this in combination with cellexitededit mode (and then do a calculation), the grid render and reaction time becomes slow.
I've done some testing with removing some columns and then performance increases dramatically.
There is a horizontal scrollbar in my grid. (so over 30 columns are initially not on the screen unless you use the scrollbar)
Is there some way to tell the xamwebgrid to ignore those columns (in a rendering way manner of speaking) when they are not visible on the screen ?
Just found this link on your help site: http://help.infragistics.com/Help/NetAdvantage/Silverlight/2009.1/CLR3.5/html/SL_xamWebGrid_Virtualization.html
I will take a look at the recommendations in it.
In CellExitedEdit mode, I get the (CellBase)e.Cell.Row.Data and add this to an ObservableCollection.
Next I do a calculation with the contents of that ObservableCollection. The grid's ItemsSource is set to this ObservableCollection.
I think the problem is basically what another Grid Vendor supplier solved and described as: Horizontal UI Virtualization. (especially with lots of columns)
It's hard to know what's going on from your initial post.
Can you provide the following information?
1. What are you doing in CellExitedEdit mode? Can you provide the code?
2. Are you doing Cell editing, or Row editing.
Thanks,
