Is it possible to use wildcards in the label filter?
Ex.: I want to filter all the days that begin with S and end with Y

I tried S*Y and it doesn't return anything.
Thanks,
Tim

Hello Tim,

With the current release we don't have default wildcards, but you can implement your own by using Regex. You can create a new class and inherit Telerik.Pivot.Core.Condition. You'll notice two important methods there:  CreateInstanceCore and CloneCore. In the first one you should create a new object from this class and in the second one you can copy all of your properties. The other very important method is PassesFilter where "the magic happens" - this is the place where you can match your regular expression.

To illustrate this we have prepared a simple project for you - please check it and inform us if you have any problems or concerns. If you want to use wildcards you'll have to add some more code - replace the "*" with ".*" on all places, add escape characters to the special regex symbols, etc...

Hopefully this helps.
