How to hide body of gridpanel?

[experts]

My grid have some docked toolbars and i want to hide only grid body. I tried to hide like this:




mygrid.body.hide();

rows disappeared but container height not changed. So instead of grid rows I got empty space..So how collapse and expand gridpanel body?




Same question here if you want some points

Try this


grid.setHeight(grid.getHeight() - grid.getView().getHeight());

[experts]

I have tried this it works when I need hide but when I try to show it body loses height so I cannot restore it.



console.log(me.getView().getHeight(),'before');
me.setHeight(me.getHeight() - me.getView().getHeight());
me.setHeight(me.getHeight() + me.getView().getHeight());
console.log(me.getView().getHeight(),'after');


and result was:

161 before

104 after


Maybe I should save height somewhere where would best place? there is not one grid those grids created dynamically

You should save the original grid height if you want to expand it again. Ex:


function collapse(grid){
if(!grid.originalHeight) grid.originalHeight = grid.getHeight();
grid.setHeight(grid.getHeight() - grid.getView().getHeight);
}

function expand(grid){
if(grid.originalHeight) grid.setHeight(grid.originalHeight);
}

Almost work just why it disappears after collapse, expand, collapse.

after some debug maybe I got why. that's because grid.body becomes to tall..


function collapse(grid){
console.log(grid.getView().getHeight(), grid.getHeight(),'before collapse');
if(!grid.originalHeight) grid.originalHeight = grid.getHeight();
grid.setHeight(grid.getHeight() - grid.getView().getHeight());
console.log(grid.getView().getHeight(), grid.getHeight(),'after collapse');


}


function expand(grid) {
console.log(grid.getView().getHeight(), grid.getHeight(),'before expand');
if(grid.originalHeight) grid.setHeight(grid.originalHeight);
console.log(grid.getView().getHeight(), grid.getHeight(),'after expand');
}


debug:


161 215 before collapse
52 54 after collapse
52 54 before expand
213 215 after expand
213 215 before collapse
213 2 after collapse
