WPF - RateBar

As per my previous post, I have been working on a WPF based progress bar. This is supposed to be similar to the  Windows 8 file transfer progress bar, I’ve named it a ‘RateBar’ as it seems appropriate. Well I’ve finished the initial version of this project and based on the popularity of the question on StackOverflow I imagine there are some other people who would benefit from the control.

I’ve not got any automated tests for it (I’ll try to add some at some point) and I don’t know if it works with WPF styles (mainly because I don’t know how they work), but it all seems to work so far and matches quite nicely based on my initial intention. To get a true windows 8 style it’ll probably need combining with an ‘expansion’ arrow which switches between a progress bar and a rate bar.

Some basic instructions to get you started. You’ll need to do the following (I hope most of which are fairly obvious):

• Add a reference to RateBar.dll within your WPF project.
• Add the RateBar namespace within your WPF window/control that you wish to include it on:

            xmlns:my="clr-namespace:RateBar;assembly=RateBar"

• Add an instance of the RateGraph, recommended size is 380×88:

            <my:RateGraph x:Name="rateGraph1" Height="88" Width="380" />

• Update Value (the progress), Rate (the current rate) and Caption (the rate info above the black line) on a regular basis.

Note: The Progress needs to change before the Rate is updated, otherwise you’ll end up with a vertical line on your graph, as the rate get’s added based on the current progress location to the graph.

I’ve included the source and release binaries in a zip file accessible from here. If you like this and would like to contribute in some way then please feel free to sign up for Dropbox if you’re not already on (free multi location file storage with cloud synchronization) using my referral link. This will give me more space for hosting source code, binaries and useful tools for the community.

The license for the code is that you may use it in any project and modify it as much as you need. Please reference me somewhere if you have a readme and if you’d like to use it for commercial use feel free to do so as long as you leave a comment so I know how many people are using it (and whether I should invest more time improving it!).
