checkbox in listgrid

[lchen]

I have a listgrid for which i have used
selectionAppearance:"checkbox",


in addition to the grid records, it shows the checkbox in grid header as well

Now I need to implement this header checkbox work like selectAll/unselectAll.

in other words, all listGridRecords shouldbe checked/unchecked on check/uncheck of the listgrid header checkbox.

please help me how to do this.

The default behavior of the header checkbox is to select / deselect the entire list.
However it can only do this if the entire data-set is loaded on the client. If you're working with a paged ResultSet, this checkbox will be inoperative and a prompt (tooltip) will be shown to indicate why.

If you're not working with a huge data-set you could change the dataFetchMode of the listGrid to retrieve all records to resolve this.
