Checkbox - Bool type

TreeGrid documentation

Bool is boolean type contains only two values 0 and 1.
Or it is possible to show three states ("", 0, 1) when set CanEmpty='1'.
It is shown as checkbox or radio button.
It supports radio groups - only one radio inside group can be checked.
Filter cell Bool type button automatically hides operator menu and sets CanEmpty='1' to have filter off option.
To define Bool type, set column or cell attribute Type to "Bool".
If the Bool cell can be empty.
If set, the Bool cell supports three states: "", 0, 1.
The states are cycled on click - for CanEmpty = 1 is ("",1,0,"",1,0,...), for 2 is ("",0,1,"",0,1) and (since 9.3) for 3 is ("",1,0,1,0,...) and for 4 is ("",0,1,0,1,...)
CanEmpty is supported only by BoolIcon = 0 or 2 and ignores BoolGroup.
If set, filter shows operator menu to let a use filter according to all three values.
Which icon will displayed in the cell.
Since 11.0 it can be also first character separated array of strings as icon files for 0, 1 and empty value, e.g. BoolIcon="|Off.gif|On.gif|Empty.gif"
There can be also three more icons for CanEdit='0' state, e.g. BoolIcon="|Off.gif|On.gif|Empty.gif|OffRO.gif|OnRO.gif|EmptyRO.gif"
0 - Checkbox image
1 - Radio button image
2 - Checkbox image vertically centered, slightly slower than 0
3 - Radio button image vertically centered, slightly slower than 0
4 - <input type='checkbox'>, it is faster than icons especially in IE, use it when many Bools are rendered in grid (500+).
5 - <input type='radio'>, it is faster than icons especially in IE, use it when many Bools are rendered in grid (500+).
6 -  X or     , it is faster than icons especially in IE strict mode, use it when many Bools are rendered in grid (500+).
Width in pixels of custom icons in BoolIcon (if BoolIcon is set to array of strings).
Three characters to show in Bool type cell with BoolIcon='6'.
In order for 0, 1, empty.
An index of radio group of Bool cells in column.
Only one cell in the group of rows (with the same BoolGroup) can be checked.
When a user checks some radio, the previously checked radio in the group is unchecked.
An index of radio group of Bool cells in row.
Only one cell in the group of cells (with the same Radio) can be checked.
When a user checks some radio, the previously checked radio in the group is unchecked.
If all the checkboxes with the same BoolGroup or Radio can be empty - a user can uncheck the checked radio.
Sets the Bool cell value to value. It is affected by BoolGroup, Radio and Uncheck attributes.
value can be 1 for on, 0 for off, empty string for clear and null for change.
If set test, does not change anything, just checks the change possibility.
Returns true for change, otherwise false.

Changes the Bool value.
Sets the Bool value to 1.
Sets the Bool value to 0.
Sets the Bool value to empty string, if CanEmpty=1.
