I’m about to develop a wpf app which will be used as a planning

  • 0

I’m about to develop a wpf app which will be used as a planning tool. The main idea is to display a table, rows are people, columns are days. Each cell is split into two smaller cells, each smaller cell corresponds to a task assigned to the employee (the row) for the day (the column).

Should look like this :

///////////// Day 1//Day 2//Day 3//Day 4//Day 5//Day 6//Day 7

People1 E1/E2 E1/E2 E1/E2 E1/E2 E1/E2 E1/E2 E1/E2

People2 E1/E2 E1/E2 E1/E2 E1/E2 E1/E2 E1/E2 E1/E2

People3 E1/E2 E1/E2 E1/E2 E1/E2 E1/E2 E1/E2 E1/E2

I need to be able to use a customcontrol as one smaller cell (one “task”).

I tried to manipulate ItemsControl, DataGrid, but everytime it was showing performance issues : either the scrolling (both horizontally and vertically) was laggy, or the time used by the app to draw the components was way too important.

As I seem to need new ideas to solve the performance issue, I was wondering if maybe someone else have had the same problem, and managed to deal with it..

Any suggestion?

    ItemsControl is known to have performance problems. You can try to switch to ListBox or ListView because they are based on a VirtualizingStackPanel.

    Also, the question WPF – Virtualizing an ItemsControl? has more information about virtualizing an ItemsControl.

    Furthermore, it was announced at the recent Build conference that .NET 4.5 will contain considerable performance improvements to ItemsControl. Ira Lukhezo sums it up in a blog entry titled ItemsControl Performance Improvements in .NET 4.5.
