Flex :: Force A ComboBox's LabelFunction To Be Called For The Selected Item When Locale Changes?
Sep 3, 2009
I have a ComboBox with a label function like this one:
private function fieldLabelFunction(item:Object):String {
return resourceManager.getString('dashboard',"SS." + item);
}
When I change locales, the labels display correctly in the ComboBox's dropdown list, or if I change a selection. However, the currently selected item's label doesn't refresh at first. Is there a way to force the labelFunction to get called again?
issue is that when a user clicks a datagrid cell that has a combobox editor and then immediately clicks away from the cell, the text value in that cell disappears. I have an itemEditEnd handler on the datagrid and it shows the value of the property I use as the editorDataField just fine. But the labelFunction (which gets called after the itemEditEnd handler) on that grid column sees it as zero. Why aren't the labelFunction and item editor playing together nicely? Here is the DataGridColumn:
I have a combobox with arrayCollection dataprovider, it selects nothing at start, but i see the first object label as selected, i want to add select text, as first option that selects nothing, just to indicate that the user didn't select an option yet.
I am using a combobox for the us states, link. The label is set to the full name of the state, while the value attribute holds the abbreviation. What I want to do is to get the selected item's value. So I tried combo.selectedItem.value and combo.selectedItem.@value, but neither of them worked.
I've just recently started out using Flash Builder and have a question surrounding states. In fact I'm not entirely sure it is related to states but read on and I hope it will become clearer. I currently have a custom component that contains 3 comboboxes. This resides in a TabNavigator component. The TabNavigator consits of 5 pages (Tabs). The custom container holding the comboboxes should display the same selected data across all Tabs. ie. If I am in Tab1 and select an item from one of the comboboxes then click on Tab2 I need to mirror the combobox's selection in Tab2.
Isn't there a better way to accomplish this?[code]...
All I want to do is make sure that when I update the item that the comboBox is pointing to internally, that it's selectedIndex also update so that the label within the ComboBox reflects the new value.
I have a combobox that act as autosuggestion for a search application. Search function is getting triggered by a search button. I also want to trigger the search function either when the item in combobox is double or single clicked. Code:
I just want to acquire the existing label from the currently selected item in a ComboBox. I populated it with a DataProvider with a list of strings and it will not allow me to get the currently selected label, especially if I input a new one, not included in the DataProvider
I have a DataGrid where one of the columns has a labelFunction. When I run the application a scrollbar shows up in the DataGrid indicating to me that it has data but there is nothing in the DataGrid. When I scroll items start showing up. When I Debugged it I noticed that the labelFunction was never being called until I started scrolling. Does anyone know why this is happening?
Flash documentation says this is possible, but cb.selectedItem={label:'labeltext',data:'data'}; is a no go for me. Maybe I'm missing something obvious? Setting selectedIndex works great, but this should work too.
When I select an item from the comboBox-list the selected item stays blank(visually) but the comboBox-list remains populated and change-event keeps firing.
This happens when I embed fonts and modifies or removes items from an existing combobox.
Here's the code that causes the anomoly: comboBox.textField.setStyle("textFormat", fontFormat); comboBox.textField.setStyle("embedFonts", true);
My first issue is that when my ArrayCollection only has one item, for some reason I cannot select that first item. The change function set on the mxml never gets called when I try to select that one item. If I set a prompt, it works. I know that the item is not already selected because when debugging, the selected item shows null. I do not want to use a prompt. I want the first item in the ArrayCollection to be selected automatically. So if there is only one item, I want the selected item to be that. FYI - I am using a labelFunction to format the data in the Array Collection. why I cannot select the first item or set the first item in the ArrayCollection to be the selected item?
My bigger issue is that when my Array Collection gets updated, my label function must not be refreshing because when I first open the dropdown, it has specfic data. When the Array Collection gets updated and I open the dropdown again, I see the old data in the dropdown, yet it doesn't exist anymore.
So let's say I have a ComboBox that has a datasource of an array collection of one state code and it's state name. Their is a labelFunction that puts a dash in between the state code and the state name. Their is no prompt, so the ComboBox would look like GA - Georgia and when you open the dropdown, that would be all that is there. I want that item to be selected automatically. why the old data shows up when opening the dropdown after the array collection was updated with new data?
<mx:ComboBox labelFunction="getFormattedNpaNxxCollectionList()" dataProvider="arrayColl" change="doSomething()"/> public function getFormattedNpaNxxCollectionList(item:Object):String { return StringUtil.substitute("{0} - {1}", item.stateCode, item.stateName); }
Because of screen size, I must ensure we're only displaying necessary data to the user.I have a drop down box that contains only 5 items and I would like that when an item is selected, it doesn't appear in the drop down box (since technically it's showing twice, once at the top as the selected item and once in the list). how I would achieve this? I tried using a custom CellRender and overriding the "set selected" function to call this.visible = false if selected is true, but that simply hides the item but does not remove it from the layout of the drop down list.
What I want to do is, when I select an item in the datagrid, the selected item of the dropdown should be the correct one (the one which has the field idCompSuperioara equal to the third element in the selected datagrid row).
I have used states in my application.The thing is I have made the first item in my list to be selected. so I gave like this,
if(itemIndex == 0) this.currentState="selected";
this works fine.The problem is when other item is selected the first item does not change its state,it remains in the selected state until its clicked.My code looks like this,
How do you force Combobox dropdowns to stay open even when other Alert boxes appear. Looking at what to subclass from mx.Combobox, there doesn't seem to be much that i can do to short of implementing an entire combobox from scratch.
I have an item renderer that checks an external source for display information. If that information changes, I want to force all item renderer instances to check it.
What's the best way for force all the item renderers in a list or grid to either commitProperties or execute some other method?
I've read that resetting the grid.itemRenderer property will make them all initialize. I've also received the suggestion to iterate recursively through all the grid's children and call invalidateProperties on all the UIComponents I find.
I had a comboBox and loading the datadynamically from the server. i need to display the first value in comboBox as a selected value and based on the value data should be populated on the grid.
When a combobox is elected in the flex app, there is a quick flicker, then the combobox needs to be selected again in order to get the dropdown to open. After that, the dropdown works as expected, but only while selecting the control subsequent times while on the form. Reloading the form requires the double selection again.
I have a menu with many sub menus. I need to change the color of the selected button and then move on to the sub menu. My menu is horizontal and now it's not obvious the path that you follow.
I have a XML based Tree Control. The XML Structure is recursive, so the children's can have the same Element as the parent. I now want to let the user add and remove the elements. Do do so I need to get the parent element of the selected Item. Following code I already collected together:
var selected:XML = treeControl.selectedItem; parent.insertChildAfter(selected:XML, newElement);
I just don't know how to get to the selected parents node as there is no such method like treeControl.selectedItem.parent.
I have a TileList with thumbnail images. Under each thumbnail images I display the name of the image. I want to build rename functionality. So under the TileList is a "Rename selected image" button.
When this button is clicked, I would like to change the state of the itemRenderer component. The label underneath the image will change into a TextInput so that the user can type a new name. This is much like the Windows rename file functionality.
How can I access the itemRenderer of the selected image? How can I make it happen that it listens to the click event of the Rename button?[code]...
I am using FlashBuilder 4.5 for PHP. I have a simple MySQL table with the fields {tID, tName}.I am able to populate a DropDownList in a Flex form as below. The DropDownList shows the name of the people without problem:
I'm having a problem with getting the value of an item that the user selects in my mobile Flex application. When I select an item from the list I place that item into an ArrayCollection. But when I check the value (trace()), the value is [object Object] and I can't seem to access the actual value of the object. Here is what I am doing:
private var selectedPlayers:ArrayCollection = new ArrayCollection(); private var numOfPlayers:int; ... //check if item is not already in selected players list
