Expanding the first grouping of a grouped grid only

[RyanPays]

Hi,

I have a requirement to expand the first grouping of a grouped grid when the grid is rendered.

Using the config property startCollapsed i can obviously start all groups collapsed but was wondering how i can start with the first view expanded and all other collapsed only.

I saw there is a private method for the grouping feature called expand which expects an ID, presumably of the grouping you want to expand.

How do i access the ID of the group i want to expand? Is this even possible to achieve?
I used the following code to determine that i need to pass an ID to the expand method:

var groups = Ext.data.StoreManager.lookup('Notifications').getGroups(),
      gridFeat = grid.features[0];

gridFeat.expand(<--ID expected as JS error 'id' is null or not an object-->);

I inspected the markup and the ID on the group body is gridview-1104-gp-Today ​but passing that into the method does not work either.

that method, expand, should have as argument group name, not an ID, thus in your case I suppose is expand('Today'). You can look in the source code of the method and understand better how it works.
