virtualmode

Hi all,

I keep getting an exception (see below) when I retrieve a list of rows from a Virtual Mode datagrid, this only happens when I have more rows than I can display on screen and it doesn't happen every time. Is there anything I'm missing with regards to virtual mode?

Update> The image below shows the problem, the index is now outside the list range. The reason for this is say I have 10 items and I hide 5 as they are not needed and I want to run some code on the 5 that are visible, there are now 5 items but the index of some maybe between 5-9, how can I re-index? When I have run some code on the visible 5 I then show the hidden 5 so I don't want to disgard these, I'd need to reindex again when they are all visible. Many thanks.

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
