I'm creating Datagrid dynamically and giving each row's first column a custom checkbox cellrenderer as noted here: [URL]. I have added an ITEM_CLICK event listener to the datagrid as such:
Code: datagrid.addEventListener(ListEvent.ITEM_CLICK, ToggleCheckBox); However, for the life of me I cannot figure out A) how to target the CheckBox specifically, B) how to toggle its' selected value, and C) how to finally update the datagrid view to reflect the toggled option.
Code:
private function ToggleCheckBox(e:ListEvent) {
// do some magic
}

[URL]I have a checkbox renderer i am placing into my Datagrid. The checkbox needs to do a sql query on the sqllite database and see if the show is marked as watched, if it is then make the checkbox as checked and if not mark the checkbox and not checked.
What i would like to do further to this is add the watched items to one XMLList and add the not watched episodes to a different XMLList and have the checkbox on click= move from one to the other list as per watched or not.

Context: I have a data grid where the following has been implemented. tabbing through each column in a single row and creating a new row when tabbing from the last column. The last column in my datagrid is now a checkbox. I set the 'editable' to false as shown below (since we don't want editable text to be shown when user clicks on/tabs to checkbox.
Problem: When I tab through the columns of a given row, I cannot tab to the checkbox column and therefore cannot use the space bar to toggle between checked/unchecked. The user is forced to use the mouse to toggle the check box. Question: How do I let user tab to the checkbox column, and press spacebar to toggle between checked and unchecked?

I have a datagrid with 5 columns. The first column has checkboxs and rest four columns have data from the dataProvider.
I have two relating issues: First: I want the row to get selected when I click on a checkbox, or if i click on multiple checkboxes, every row should stay selected in the datagrid for whose checkbox is selected.
Second: If a row or multiple rows are selected, the corresponding checkbox should get selected too.
My code is given below:
<mx:DataGrid id="dg_trashContent" allowMultipleSelection="true"
verticalGridLines="true"
dataProvider="{trashDataProvider}"

I have a small flex datagrid. The dataProvider is an xmlList. I have two columns, userList and user permissions. The user permissions column as checkboxes. The values for the checkbox are stored as 0 and 1 in mySQL. While returning it from PHP, I am converting them to true or false. Its returning the values correctly to the frontend.
But inside the itemrenderer, the checkbox is not being set to true or false.
Either everything is true or everything is false.

How can i add and remove rows in datagrid using check box`
[Bindable]public var _files:Array = new Array();
private function init():void{
_files = new Array();
for(var j:int=0;j<10;j++){
[code]....
in the above code if i select check box i need to add row if i deselect i need to remove the row how can i do that ?
I receive my parameters as 1's or 0's to fill a datagrid full of checkboxes. The funny bit here is that the checkbox control recognizes them as booleans! But then my checkbox control has a change property in which these numbers are converted to "true" or "false".How can I convert this changes to ones and zeroes again to send them back to database?I believed the ByteArray function "writeAsBoolean" would work, but I forgot the rest of the values inside the datagrid are kept as numbers. So that function will not recognize them and my webservice will ignore them, failing to write the data.
