Mention that the personalization is stored with the widget ID about yii2-dynagrid

@thelfensdrfer - could you explain your issue a bit more (mention code snippets if needed)?

The widget internally generates an unique id if you do not provide one. So the behavior should technically be the same if you provide an ID or do not.

Ok that is strange. I had multiple pages with grids (different routes/controllers/actions). One grid per page. Before I set an unqiue ID to the widgets, some of them hide all the columns, but not the first I opened. I could show them with the personalize modal so I thought they were hidden because the settings were saved for the first grid widget and the later did not find the saved (cookie) columns of the first one so they got hidden?

I think I understand this - will record a fix for this.

The DynaGrid options['id'] is mandatory. A fix has been provided via commit 80e6fed to validate this and throw an exception if its not set. The docs have also been updated for this.

Great, thank you! Did you validate the issue?

Yes - the auto generated id will work for the storage type session but not for cookie and db. Since, the auto generated id is a random identifier and will not be the same each time for retrieval.

Its better if this control is given to developer to define one's own unique id and make the code simpler and faster.
