Flex :: Setting A Custom ItemRenderer In A ComboBox On Specific List Items After Combobox Creation?

Nov 8, 2010

I'm trying to set a specific list item in a mx combobox to have a custom item renderer, the problem is that I cannot do this via mxml, it needs to be done via actionscript at a later stage, eg: combobox gets created, combobox gets populated, user does other tasks, combobox needs to set one or more items in the combobox to have icons (via item renderer)..

I can do this via the onChange event, but it only applies the icon when the combobox is opened and there is a slight delay so you can see the icon being added.

ActionScript 2.0 :: Combobox Same Value?

Apr 29, 2011

I can use this to trace the new combobox value every time the user changes it:

Actionscript Code:
// Create listener object.var cbListener:Object = new Object();// Create event handler function.cbListener.change = function (evt_obj:Object) { trace("Currently selected item is: " + evt_obj.target.selectedItem.label);}// Add event listener.my_cb.addEventListener("change", cbListener);

But that doesn't do anything when I select the same value. This is what I want it to do: when using the combobox some textfields should fill itself with some default values belonging to that label. Then the user can change those values if desired. When the user then chooses another combobox label the fields get filled with the default values of that label again. But when the user chooses the label previously set, the textfields don't get refilled, cause the listener object only reacts when the label value has been changed, not when the label value is the same as previously chosen. Is there a way to make it react upon chosing any label? Not just others, but every label?

ActionScript 1/2 :: Using ComboBox To Populate

Mar 8, 2011

If I have a ComboBox component on stage and it has 11 options in it, is it possible to populate a dynamic text field with text based on which one of the 11 options are selected?ComboBox has instance name of 'age' and has 11 options to choose from (Opt1, Opt2, Opt3, Opt4, Opt5, etc.).There are also 11 dynamic text fields (instance and variable names of c1, c2, c3, etc.). I want the text fields to be blank unless the corresponding option is chosen. So, if Opt1 is selected from ComboBox 'age' then populate 'c1' with the number 1, if 'Opt2' is selected populate 'c2' with 2 and so on, otherwise the text fields stay blank.

Flex :: Get The Value Of A ComboBox That Is In A DataGrid?

Oct 6, 2009

I have a data grid that has ComboBoxes in two of its columns.

What I need to do is get the values of those bombo boxes when a user highlights the row of the grid NOT when the user uses the comboBox. I understand how to pull the values out once the change handler is invoked on the comboBox, but I'm not seeing a way to get at the comboBoxes that belong to the currently highlighted gridRow.

I'm sure it's really straight forward, but I'm just not able to find any reference on how it's done.

Flex :: Get The Value Of A ComboBox Within A DataGrid?

May 12, 2010

I have a DataGrid with a ComboBox as an ItemRenderer for one of my columns. When the user selects a row, I want to get the ComboBox's selected value for the selected row.

EDIT: I should have mentioned that the dataField2_Array property in myData is actually an Array is the dataProvider for the ComboBox. Each object in myData could have completely different values in that Array so the ComboBox in each row of the DataGrid could have completely different options to pick from.Some sample code:

<mx:DataGrid id="myGrid"
dataProvider="{myData}">
<mx:columns>[code].....

Flex :: Sorting - Get Value In ComboBox

Sep 26, 2011

I have a one comboBox that I fill as:
for (var key:String in values) {
conns.addItem(key);
}

After that I sorted my ComboBox as:
private function sortConnection():void {
var dataSortField:SortField = new SortField();
dataSortField.name = "data";
dataSortField.numeric = true;
var numericDataSort:Sort = new Sort();
numericDataSort.fields = [dataSortField];
conns.sort = numericDataSort;
conns.refresh();
}

And on finish I want to select item on my specific value in ComboBox. How can I do that? I try:
for (var ii:Number=0; ii<combo.rowCount; ii++) {
var item:String = combo.getChildAt(ii);
if (item == name) {
index = ii;
}}
But does not work. I do not know where I made mistake, and how I can select on specific item in my combobox.

ActionScript 2.0 :: Use The Combobox Function That MX?

Jul 19, 2002

I want to use the combobox function that MX has, but how do script it? The one that I've got from the help site is quite vague(I guess that is why I spent more time in flashkit and kirupa more than Macromedia site, even the help-forum is not that user friendly{personal commnets}), that is

function onChange(component){
if (componet._name=="check1"){
listBox1_mc.setEnabled(componet.getValue());{
else_if (componet._name=="check2"){
listBox2_mc.setEnabled(componet.getValue());}
}

I would understand that this could be a lenghty subject, maybe somebody could guide me to a place that I could get a tutorial?
