Sets or retrieves the height of the grid header row. Each header row can have a different height (in the extended grid with multiple header rows).
var value = obj.getHeaderHeight();
obj.setHeaderHeight(value);
obj.onHeaderHeightChanging = function(value){...};
obj.onHeaderHeightChanged = function(value){...};
obj.onHeaderHeightError = function(value){...};
Simple grid -
obj.setHeaderHeight(40);
Extended grid (several header rows) -
obj.setHeaderHeight(40, 0); // first line of headers
obj.setHeaderHeight(20, 1); // second line
How to: Multiline text in headers
Grid templates: headers
Header model: count, indices, visible, height
