abstract member GetHeightForRow : UIKit.UITableView * Foundation.NSIndexPath -> nfloat

Table view.

indexPath
NSIndexPath

Location of the row.

Attributes

Remarks

This method allows rows to have different heights (for example, rows that contain a variable number of text lines). If this method is implemented, it overrides the RowHeight property set on the table view, for the row at indexPath.

There are performance implications to using this method instead of RowHeight: every time a table view is displayed it calls this method for each of its rows. This can result in poor performance when the table has a large number of rows (for example, 1000 rows or more).
