Enable / disable combo box in datagrid cell

I have a datagrid with 8 columns 2 check boxes a text box and
5 combo boxes. I am trying to disable the combo boxes if the first
check box is not checked. So far I am able to disable the entire
column with the combo box in it, but what i am trying to achieve is
if the check box is false then the 5 combo boxes are to be
disabled.
So what I am asking in a nutshell is is there a way to enable
or disable particular cells in a datagrid ?
Example
of what I have already done
Any suggestions will be gratefully received.

I put the following code in that I took from samples:
Bindable]public var test:ArrayCollection;
private
function init():void
test =
new ArrayCollection([{label:"High", data:"high"},{label:
"Medium", data:"medium"},{label:
"Low", data:"low"}])
Then in the mxml:
<mx:DataGridColumn
headerText="From Fiscal Period">
<mx:itemRenderer>
<mx:Component>
<mx:ComboBox dataProvider="{test}">
</mx:ComboBox>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
I still get the same error: 1120: Access of undefined property test.

Disabled combo boxes don't display properly after loading a movie.

Hi,
I have a main movie that contains some combo boxes. Some of them may be disabled.
By pressing a button I load another movie using loadMovie. The loaded movie also contains combo boxes.
When the button is pressed, the clip that shows the combo boxes is removed from the stage and the loaded movie is displayed. By pressing another button, the loaded movie is unloaded and the clip with the combo boxes is displayed again.
Well, once the other movie has been loaded, when I go back to the clip with combo boxes, the disabled combo boxes have a small gray button covering the black down arrow.
I have determined that so long as the loaded movie contains combo box in the library, the problem occurrs, even if there is no actual instance of it.
The combo boxes that are not disabled are not affected. The combo boxes are disabled by setting "cb_name.enabled=false".
If the combo box is enabled, it displays correctly, but if disabled again, it goes wrong again.
My project is targeting Flash 8, so it uses AS2.
I'm using Flash CS4.
This is a very simple example I did to make sure I wasn't doing anything funny:
Initially:
After pressing the button:
After pressing the other button:
The behaviour in a web browser is the same...
I hope someone can help me with this. Thanks in advance!

Thanks for the response.
The "Load the movie" button:
on(click)
    _parent.gotoAndStop(2);
The 2nd frame:
loadMovie("Test another child.swf",Container);
stop();
The "Unload and go back" button:
on(click)
    unloadMovie(_parent.Container);
    _parent.gotoAndStop(1);
Container is a movieClip with a dark gray square shape the size of the movie clip that is loaded. It doesn't exist on frame 1, only on frame 2.
The combo boxes are inside a movie clip, and this is only on the stage on frame 1.
This and the captures belong to a very simple test I did. If there is a way of posting files, I can post a zip file with the two .fla and the two .swf.

Disable Combo Box Wrapping?

Is it possible to disable combo box wrapping? I would like to right-justify text in a combo box and display the right-most characters if the text is larger than the size of the combo box. Currently, if the text is larger than the box, it appears left-justified due to wrapping.
Thanks

Hi LVB,
I see what you are running into, but unfortunately word wrapping cannot be disabled in a combo box. You'll have to find some other way to set up your UI. Of course, you can always submit a product suggestion for this option.

Combo box in datagrid

Hello,
I have combobox in my datagrid, the combo box is as follow:
        <fx:Component id="inlineEditor">
            <mx:ComboBox >
                <mx:dataProvider>
                    <fx:String>MR. ONE</fx:String>
                    <fx:String>MR. TWO</fx:String>
                    <fx:String>MR. FOUR</fx:String>
                    <fx:String>MR. FIVE</fx:String>
                </mx:dataProvider>
            </mx:ComboBox>
        </fx:Component>
And my datagrid is;
    <mx:DataGrid id="dataGrid" editable="true" x="167" y="119" creationComplete="dataGrid_creationCompleteHandler(event)" dataProvider="{getAllResult.lastResult}">
        <mx:columns>
            <mx:DataGridColumn headerText="id" dataField="id" editable="false"/>
            <mx:DataGridColumn headerText="name" dataField="name"/>
            <mx:DataGridColumn headerText="surName" dataField="surName"
                               itemEditor="{inlineEditor}"
                               editorDataField="selectedItem" />
            <mx:DataGridColumn headerText="unitId" dataField="unitId"/>
            <mx:DataGridColumn headerText="datum" dataField="datum"
                               itemRenderer="mx.controls.DateField"
                               rendererIsEditor="true"
                               editorDataField="selectedDate"/>
            <mx:DataGridColumn headerText="company" dataField="company"
                               itemRenderer="mx.controls.CheckBox"
                               rendererIsEditor="true"
                               editorDataField="selected"/>
        </mx:columns>
    </mx:DataGrid>
Now this works fine with the values from the combobox. The issue here is that I need the combo box to be populated from a table/model, normaly I would use outside of the datagrid:
    <s:ComboBox x="138" y="399" id="comboBox" creationComplete="comboBox_creationCompleteHandler(event)" labelField="name">
        <s:AsyncListView list="{getAllResult2.lastResult}"/>
    </s:ComboBox>
And this would work fine. But how to use this combobox in the datagrid. I use LCSD for DMS.
All help is appriciated

Combo Box inside dataGrid

I have looked everywhere and I am having a hard time finding

Programatically enable-disable check box"play user interface sound effects"

Hello All,
I have been Working on something where i need to disable the "play user interface sound effects" check box ( Under System preferences under sound panel ) for few seconds and then enable the same programically without any user interface appearing on the screen. I know something related using the Applescript however there is a user interface appearing there which doesn't serve the purpose please help with some solution.If you could provide the exact location of the plist file which holds this information then that could help as well.

Hi !
I too have been working with the sounds ( Which i think is relates to @mit's query ) in an application and the problem is that when ever that application moves something to trash there is a sound which comes the sound of "throwing things in the trash". This is very annoying and i want to do something so that I can suppress that sound atleast for the time this application is on. Now is there some way where I can do this Programically . It would even be fine if I could turn off the user interface sounds completely for sometime and then bring them back on.
Thanks In Advance !
Looking Forward To Some response soon !

Add a Drop down menu / Combo Box into a specified cell of a multi column lsit box

Hello,
i have a question how to manipulate a cell of a multi column list box in that way that i can add a drop down menu or a combo box in this cell?
Is this possible in LabView?
Thank you!

Wow, I took a look at the alternate code posted here at that really takes you through gyration (also a similiar comment I see on Lava) to perform what I've done with a few functions....
See the Pics and attached VI for how its done. KISS, I added an event stucture and changed my first enum case to " " (i.e. a blank) to make it look like the other posted code....

Cmfctoolbarcomboboxbutton, how to enable/disable

Hi,
I inserted a CMFCToolBarComboBoxButton object in my toolbar. all work fine except enabling and disabling ComboBox according state of my App.
I used EnableWindow but the control still actived.
Any idea?
Tanks.
My creation code :
if (wParam == IDR_MAINFRAME24) {
m_ComboButton = new CMFCToolBarComboBoxButton(ID_MONTH_FILTER, GetCmdMgr()->GetCmdImage(ID_MONTH, FALSE),
CBS_DROPDOWNLIST);
CString strMonths, strMonth;
int i, curPos = 0;
if (strMonths.LoadStringW(IDS_MONTHS)) {
i = 1;
//m_ComboButton->AddItem(_T(""), 0);
strMonth = strMonths.Tokenize(_T(";"), curPos);
while (strMonth != _T("")) {
m_ComboButton->AddItem(strMonth, i);
strMonth = strMonths.Tokenize(_T(";"), curPos);
i++;
m_wndToolBar.ReplaceButton(ID_MONTH, *m_ComboButton);
CMFCToolBarComboBoxButton * pMonthCombo = CMFCToolBarComboBoxButton::GetByCmd(ID_MONTH_FILTER, FALSE);
if (pMonthCombo) {
pMonthCombo->SetCenterVert(false);
pMonthCombo->SetText(_T("Advanced filter"));
pMonthCombo->EnableWindow(FALSE);

Tank you for your help.
you are right, but a update cammand ui message is not send by CMFCToolBarComboBoxButton object.
I make a test on my side and mesajflaviu's suggestion really helpful. Using ON_UPDATE_COMMAND_UI macro, I can disable the CMFCToolBarComboBoxButton in the CMFCToolBar. See my test code snippet:
BOOL m_enable; //use to detect if enable the combo box
afx_msg void OnUpdateCombo(CCmdUI *pCmdUI);
ON_UPDATE_COMMAND_UI(IDR_COM, &CMainFrame::OnUpdateCombo)
void CMainFrame::OnUpdateCombo(CCmdUI *pCmdUI)
pCmdUI->Enable(m_enable);
void CMainFrame::OnEditDisable()
// TODO: Add your command handler code here
m_enable = FALSE;// use a menuitem to disable the combo box
///////create the CMFCToolBarComboBoxButton//////////
LRESULT CMainFrame::OnToolbarReset(WPARAM wp, LPARAM lp)
UINT uiToolBarId = (UINT)wp;
TRACE("CMainFrame::OnToolbarReset : %i\n", uiToolBarId);
switch (uiToolBarId)
case IDR_TOOLBAR1:
m_ComboButton = new CMFCToolBarComboBoxButton(IDR_COM, GetCmdMgr()->GetCmdImage(IDR_COM, FALSE), CBS_DROPDOWNLIST);
m_ComboButton->EnableWindow(true);
m_ComboButton->SetCenterVert();
m_ComboButton->SetDropDownHeight(25);
m_ComboButton->SetFlatMode();
m_ComboButton->AddItem(_T("OPTION1"));
m_ComboButton->AddItem(_T("OPTION2"));
m_ComboButton->SelectItem(0);
m_wndToolBar.ReplaceButton(IDR_COM, *m_ComboButton);
break;
return 0;
Check the result screenshot:
Enable:
Disable: Color is turning yellow and cannot click

Problem rendering a combo box in the data grid

Hi,
I am rendering a combo box in the data grid control using an
item renderer. When I click on it to select a value from the drop
down, the combo box immediately closes giving no time to even click
on the dropdown. This doesn’t happen every time the combo is
clicked, although it happens frequently. What I think is that the
problem arises because the data grid tries to refresh the renderers
and during this process, the existing combo is removed, thereby
getting closed automatically. Please let me know of a work around.
Thanks,
Cheree

hi hiwa,

Tab Component Dynamic Visibility to Combo Boxes

I am using a Tab component. I have 3 tabs on my dashboard. I have 2 Combo boxes that I am using to filter rows of data on 3 Excel sheets. Both Combo boxes are not used on all the tabs. How can I pass example: User clicks on Tab 1 and use dynamic visibility for Combo Box 1 and Combo Box 2 are visible. If the user clicks on Tab 2 I want only Combo Box 1 to be visible.

Hi Joe,
This can be achieved in Dynamic visibility.
On click on Tab,just map to some target(say value "1") and then For Combo box,set target cell mapped for tab to 1,which means when the target cell gets "1",show the Combo box.
If you are not clear then you can refer the following URL,which will give you more informations about this.
