Use a column renderer.

once you figure out how to implement custom column renderers, you can then do this:

I have check/Uncheck field in Editable Grid.
When I check Uncheck a cell , It makes whole record dirty.
I want to Select All / Unselect All. But It makes whole grid dirty.
I want a field that does not contribute to the dirty state of datastore. ??
Any Solution.??

Make an effort yourself.

Simply add a function :

function myCheckbox(val)
{
if(val == 0){
return '<input type="checkbox" />' ; //here we can have anytype of control}else if(val == 1){
return '<input type="checkbox" CHECKED/>' ;//here we can have anytype of control
}
return val;//'<input type="checkbox" name="vehicle" value="' + val '"/>';
}

Now in your column modal add a column as follows

var colModel = new Ext.grid.ColumnModel([
{header: "#",width: 30, dataIndex: 'SelectItem',
renderer: myCheckbox,
},
.....
.....

Note: We are getting data from a dataset with column named 'SelectItem'
this column as data in 0 and 1 only indicating unchecked or checked respectively
