Similar to Excel - RadPivotGrid could have an area, where you can select some filter/group descriptions.
Currently when you have null value in a cell, RadPivotGrid considers it as 0. This way when you apply some Aggregate Functions, like Average for example, the result may not be as expected. For example if you have the cells 10, null, 10 RadPivotGrid will show as total the value 6.67 (for Average function). You should be able to exclude null values, so the value 10 will be shown as average for the mentioned cells. Available in the 2016 R2 release.
Implement: "% of Parent", "% of Parent Row", "% of Parent Column"
Hour, minute, second.
Add support for Hours/Minutes/Seconds steps. Also, add a DayNumber option.
Add support for frozen columns. Like in RadGridView or Excel. This way you can scroll the data horizontally while part of the columns are frozen and you can always see them.
We can also consider adding frozen rows like in RadGridView or Excel.
In the RadPivotGrid: Open the Label Filter dialog on a dimension, don't set anything and press OK, then all items are present and nothing is filtered out as expected. Open the Label filter again and manually specify that the value must equal "xyz" and click OK then it will exclude every item that doesn't match this. Again, this behaviour is what you'd expect. If you then open the dialog, and delete the "xyz" from the textbox so that the dialog appears exactly as it did originally, and click OK then you won't see any items in your pivot grid. This is because it is now filtering out anything that doesn't have an empty string as the label. This is not what I'd expect. To remedy this, you can click on the dimension and see that the Label filter is still ticked in the context menu, and click "Clear filter", but this isn't exactly intuitive. I'd like the filter to be cleared when you clear the text in the box.
