Description
I came across this problem trying to dynamically show a hidden cell in my TableView. I set the height of the Cell to 0 and then after conditions are met to 42 (approximately standard iOS height). After calling ForceUpdateSize() on the cell, the resizing works fine but the layout inside is hidden until i manually tap the cell in the UI.
PS: if anyone is able to help me manually call a tap on the cell i would be fine with a "hacky" solution aswell.
Steps to Reproduce
- Create a TableView with UnevenRows="true"
- Create a cell inside the TableView, set it's height to Zero
- Set the cells height to a certain number like 42 and call ForceUpdateSize()
- The layout inside the cell is hidden.
Expected Behavior
The layout inside the cell should be visible.
Actual Behavior
The layout inside the cell is hidden until i tap it.
