I have a table "template" that is used in various "examples" in all instances in the second column the checkbox Are (for record-delete).
What will be the most effective way to run on the table and check that at least one checkbox is selected (to enable the "Delete" button)?
From the table, do you mean the datagrid?
You will need to store the "checked" status of each column in your data provider. The datagrid renderer uses recycling, so there is only one record shown on the screen.
If you check something, and then scroll down so that some screen that has been screened closes; You will not have any records that were examined.
