R – Flex: Using NumericStepper as an itemEditor in a DataGrid

apache-flexdatagriditemeditor

I am trying to make one field in a datagrid editable with a numeric stepper. My current attempts look like they are working, but the dataProvider is not actually being changed.

Based on what I have read in a billion different places, the syntax should be

< mx:DataGridColumn dataField="a" itemRenderer="mx.controls.NumericStepper" rendererIsEditor="true" editorDataField="value" / >

I have tried several variations on this theme, and nothing seems to work. What am I missing?

Without any more info, I would guess that your dataProvider is not declared as Bindable.

Solution: Instead of using RadioButtons as the itemRenderer, I used an image, which works much cleaner and doesn't produce so much unpredictable behavior.

Flex – Sending a parameter to a custom ItemRenderer

You may want to look into ClassFactory from the Flex APIs:

This allows you to set a prototype Object with arbitrary types / values each of which will be passed to the item renderer. From the sample:

var productRenderer:ClassFactory = new ClassFactory(ProductRenderer);
productRenderer.properties = { showProductImage: true };
myList.itemRenderer = productRenderer;

The above code assumed that "ProductRenderer" has a public property called "showProductImage" which will be set with a value of "true."
