    Datagrid itemRenderer dynamic values

    Ventis85 Level 1
      While working on an application I came across the following problem. I've got a view with a datagrid, where I have several columns. Each column needs 2 values displayed beneath each other in one cell. You make an itemRenderer with 2 labels inside a VBox. Easy so far. However since this scenario repeats several times it seems counterproductive to make an itemRenderer for each cell. How can I make the text property for the labels change for each cell instead of being static in their values.

      Thx in advance.

          Your description of your requirements and your sample code do not paint a clear enough picture.

          Your dataProvider has 4 pieces of data: batchId, bookingNumber, valueDate, immsBranch. Your current itemRenderer references two of those pieces of data, and you say you want to reference the other two. You can do that easily like this:

          <mx:Label text="data.valueDate"/>
          <mx:Label text="data.immsBranch"/>

          A basic question: will your DataGrid have two rows for each set of 4 pieces of data? If so then I understand your problem. If not, then you must clarify exactly how and when you would like the 4 pieces of data shown in your DataGrid.

          In any case, you probably need a Repeater, and then need to figure out how to get at the right data at the right time in the Repeater.

          See this FB 3 help topic and its sub-topics:

          Dynamically Repeating Controls and Containers

          Also search for this in the FB3 help to see the API:


          You can define a listener for the Repeater for the Repeat event to specify processing for each iteration of the repeater.

            Actually I want 2 columns with 2 pieces of data in each row. My problem is that I don't want to make an itemRenderer for each column, because every cell in each column basically has 2 labels, only the data changes.

            The reason I need it to be dynamic is because I will have multiple rows, not just one value like in the example. The filled in values are just for testing purposes.

            Thx for your help so far.
