Hello,

I am creating my own custom aggregate function to calculate the sum of the cells in my column based on a property of my row. I have created my own function class. I am inheiriting from AggregateFunction with element/result:  < Row, double>. I am passing in the rows of my grid. I am trying to make this as generic as possible, but I cannot seem to get a hold of the column sender. My columns are created dynamically. So my logic is happening for every column this function is being set up on. 

Thanks,

Hello Doug,

You can see this online example, which shows how to create a custom aggregate function. The demo is for Silverlight, however the same approach works in WPF.
