Question

Here’s my request :

I have an EditorGrid which renders some rows based on its associated ListStore.

The ListStore has a collection of instances of my model which has an attribute called “markeAsDeleted” which is updated elsewhere in the UI.

My question is :

How is-it possible to change the rendering of the corresponding row to turn it ‘disabled’ when my ‘markAsDeleted’ attribute is ‘true’ ?

What’s I’m expecting is a kind of a rendrer to add to my EditorGrid instance which updates the row as the model attribute is updated.

Thanks

Hiding the column with filtering would be your best best.

If you set store.setMonitoChanges(true); then I believe it will reconise when anything changes that model in the store and fire an storeUpdate from there you could re-Apply your filter (if it doesnt do that automatically anyway);

example

store.addStoreListener(new StoreListener<BaseModelData>() {
  public void storeUpdate(StoreEvent<M> se) {
      store.applyFilters("");
  }
})

edit:
After reading the comments on another answer I notice you are using a Grid filter to filter the columns you could just as easily use addFilter on a store.

example

store.addFilter(new StoreFilter<BaseModelData>() {
   public boolean select(Store<T> store, T parent, T item, String property) {
      return !item.get("markAsDeleted");
   }
});
