I have a form that consists of two data grids and a button. Datagrid 1, "myStaticDataGrid", has values I have added for the user to select from. I want the button's click event to send the current selection of myStaticDataGrid to the second datagrid, "myDataGrid". I have been able to accomplish this if I use a text box and a datagrid but I am having trouble finding the right syntax to grab the selection data from myStaticDataGrid.
This is my attempt using the two datagrid approach:
<s:Form id="m开发者_如何学CyForm">
//The values from this grid are determined once the button is clicked.
<s:FormItem id="myDataGrid">
<s:DataGrid id="bdgFormData">
<s:typicalItem>
<s:DataItem formData="Description" xmlData="Value"/>
</s:typicalItem>
<s:ArrayCollection id="values"> </s:ArrayCollection>
</s:DataGrid>
</s:FormItem>
//The values from this grid are determined at runtime.
<s:FormItem id="myStaticDataGrid">
<s:DataGrid id="userSelects">
<s:typicalItem>
<s:DataItem selects="Typical Item" codes="0000"/>
</s:typicalItem>
<s:ArrayCollection id="selects">
<s:DataItem selects="Y" codes="1"/>
<s:DataItem selects="N" codes="0"/>
</s:ArrayCollection>
</s:DataGrid>
</s:FormItem>
<s:FormItem label="Add Selects">
<s:Button label="Go" click="addData(event)"/>
</s:FormItem>
My AS event to send the data:
protected function addData(event:MouseEvent):void
{
//Put selected data at the top of the grid.
items.addItemAt(lstFormData.typicalItem,0)
}
My question is where do I bind the grid data?
This is how I send the textbox data to a the datagrid:
<s:FormItem label="myDataUtil">
<s:Label text="Value"/>
<s:TextInput text="@{lstFormData.typicalItem.formData}"/>
</s:FormItem>
I whipped this up for you unfortunately I only have flex 3 here so you will have to make conversions for whatever you need but you should get the idea of how it works.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init()">
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
[Bindable]
public var originalData:ArrayCollection
[Bindable]
public var changingData:ArrayCollection;
public function init( ):void{
this.changingData = new ArrayCollection( )
this.originalData = new ArrayCollection( )
for( var i:int = 0;i<100;i++){
var obj:Object = new Object( )
obj.label = 'slot '+ i;
obj.value = 's'+i;
originalData.addItem( obj );
}
}
public function onSelect( e:Event ):void{
this.changingData.addItem(( e.currentTarget as DataGrid).selectedItem )
}
]]>
</mx:Script>
<mx:DataGrid id="myStaticDataGrid" dataProvider="{originalData}" click="onSelect(event)"/>
<mx:DataGrid id="bdgFormData" dataProvider="{changingData}" x="240" y="0"/>
</mx:Application>
Here is an example without binding data
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" >
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
public function onSelect( e:Event ):void{
var targetProvider:ArrayCollection = ( bdgFormData.dataProvider as ArrayCollection )
if( !targetProvider ){
targetProvider = new ArrayCollection()
}
targetProvider.addItem(( e.currentTarget as DataGrid).selectedItem )
bdgFormData.dataProvider = targetProvider
}
]]>
</mx:Script>
<mx:DataGrid id="myStaticDataGrid" click="onSelect(event)" >
<mx:dataProvider>
<mx:ArrayCollection >
<mx:Object label="AIR" />
<mx:Object label="ColdFusion" />
<mx:Object label="Dreamweaver" />
<mx:Object label="Flash" />
<mx:Object label="Flex" />
<mx:Object label="Photoshop" />
</mx:ArrayCollection>
</mx:dataProvider>
</mx:DataGrid>
<mx:DataGrid id="bdgFormData" x="240" y="0"/>
