I am using a DataGrid with a column of comboxes. The comboboxes represent the plot type (line, area, column, etc) for a graph. To get the comboxes to display in the column, I use a custom item renderer:
But now, I'd like to put a checkbox in the header to constrain all the lines to the same type. So that if the box is selected, I can have all the items in the dataGrid constrained to the same type. How would I go about doing this?
