Today I’ll talk about a problem that may occur when you want to filter the contents of a webpart via the connection with another webpart.
It may happen that the filter does not apply correctly on the “consumer” webpart .You see the symbol of filtered column but all the content is displayed.
Some webpart uses a rendering effect on “client side” (including standard webpart displaying “task” list).
To have your filter working, you can specify at the “consumer” webpart to use a server side rendering.
To do this, edit the properties of the “consumer” webpart. In the “Miscellaneous” section, you should see “Server Render” property unchecked. Check this property and your filter should applied.
Side effect: The initial report of the “consumer” webpart may be altered by this change, this is the case for the sample I used (task list) : Activating the “Server Render ” will remove the checkbox on tasks (the one that allow you to completed a task quickly).
Hope this helps.
