Access to CheckBox in a DataGrid
Hi everyone,
Not used Flex/AS3 for some time and am after some information.
If anyone can help:
I have a Spark dataGrid with:
Column1 = some text
Column2 = Checkbox
I wish to check to checkbox when any part of the row is clicked.
Now I know which row has been clicked, but how the hell do I set the
checkBox to be checked/unchecked.
FYI:
I am using FlexSDK 4.16 and AIR SDK 29.0.0.122
Many thanks to anyone who can reply
CODE:
==============================
[Bindable]
public var countryData:ArrayCollection = new ArrayCollection
([
{value:"France", code:0},
{value:"Japan", code:0},
{value:"India", code:1},
{value:"Russia", code:0},
{value:"United States", code:0}
]);
private function selectionChangingHandler(evt:MouseEvent):void
{
trace("Row Selected = " + dg.selectedIndex);
}
==============================
<s:DataGrid id="dg" width="85%" editable="false"
dataProvider="{countryData}"
selectionColor="yellow" sortableColumns="false" enabled="true"
click="selectionChangingHandler(event)">
<s:columns>
<s:ArrayCollection>
<s:GridColumn dataField="value" headerText="Country"
width="90%" editable="false"/>
<s:GridColumn headerText="Delete" dataField="active"
rendererIsEditable="true" width="15%" editable="true">
<s:itemRenderer>
<fx:Component>
<s:GridItemRenderer>
<s:CheckBox id="cb1" selected="false"
horizontalCenter="0" verticalCenter="3"/>
</s:GridItemRenderer>
</fx:Component>
</s:itemRenderer>
</s:GridColumn>
</s:ArrayCollection>
</s:columns>
</s:DataGrid>
==============================
Phil.

Another way is to have a custom renderer that checks its index and the DataGrid's selectedIndex and decides whether to display the check or not. The index and reference to the DataGrid are in the "listData" property of a custom IDropInListItemRenderer (which is of type DataGridListData).
I'm not sure one way is better than the other. Also, some folks don't even use a real CheckBox, they just display the graphic.

Hi,
one way is to introduce a boolean flag, e.g. 'checked' within your data
model which is 'countryData'.
After clicking a row, you have to set this flag to 'true' for the related
row.
Within the item renderer, you have to evaluate the 'checked' property in
order to update the 'selected' property of the checkbox.
Hope this helps!
