ListGrid select checkbox question

[jasmith]

In the Smart GWT Showcase example:

http://www.smartclient.com/smartgwt/showcase/#grid_interaction_checkboxselect

How can I get the ListGridField column header checkbox to be selected by default? The Showcase example has all checkboxes as unchecked?

[Isomorphic_Paul]

The header checkbox reflects the current selection within the grid.
You could call selectAllRecords() on the grid after populating it with data.

[jasmith]

listGrid.selectAllRecords(); had no affect on the top header checkbox? The records in the grid are selected, but not the header checkbox.

Please advise.

How can I access the ListGrid column header checkbox to explicitly toggle the value?

[Isomorphic_Paul]

The header should be toggled automatically to reflect the selected state of the data -- once all records are selected it will show up selected, otherwise unselected.
If this isn't happening for you, can you post a test case? It's working as it should for us.
If you want explicit control over the header checkbox to indicate some other state, it's probably best to define a separate ListGridField with custom behavior / custom title / custom icon and using the headerClick event, rather than attempting to leverage the existing checkbox field.
