View Full Version : Grid RowExpander and states

23 Dec 2010, 4:10 AM

i got my RowExpander stateful. Now i try to expand the rows where the state is set but i have problems finding the right place to do so.

I read the states in

grid.on("beforestaterestore", this.applyState, this);
Now i have an object with
[id]: [true/false]

To expand the row i have to get the rownumber, so i need to ask the store for the index of this id

index = grid.store.indexOfId(key);
but all events i try i'm too early, the store isn't filled at this point. Tried afterrender, show, viewready events.

Where is the right place to do this?

viewready (if the store is already loaded) and otherwise the store load event.

condor, right :) i should have known that ...

grid.store.on('load', this.onStoreLoaded, this);
onStoreLoaded: function(store, records,options) {
var index = -1;
for(var key in this.state){
if (this.state[key] === true) {
index = store.indexOfId(key);
if (index > -1) {

works perfect. Thanks.

FYI: i added state support to the RowPanelExpander plugin, see the code here:
