I hava a TextInput within mx DataGrid gridColumn itemrenderer and binding its text to {data.f1} ,
when I set DataGrid dataProvider column (0,0) to "value1" by actionsript code,
it will update "value1" to TextInput field.
But if I change to spark DataGrid, TextInput Text won't be changed.
Please see below two samples, when user click "set var" button, it set dataProvider column (0,0) to "value1",
sample1 is in mx comopent, it works fine and will update "value1" to TextInput Text.
sample2 is in spark component, it did not work.
anyone can help for spark component ?
many thanks.
