Show border color in AdvancedDataGrid selected row in Flex

Question

How can I show the borderColor of selected row in AdvancedDataGrid in Flex 4.6. You can see the following image for your reference.

Answer 1

Selected row is in the AdvancedDataGrid realized through dedicated Sprite, which is used as a canvas for drawing. To create border in the selection marker you need to create a custom class based on the AdvancedDataGrid and override protected method drawSelectionIndicator.

The following example should produce a selection marker with 1px wide red border:

public class GridWithBorderedSelectionMarker extends AdvancedDataGrid {
    override protected function drawSelectionIndicator(
            indicator:Sprite, x:Number, y:Number, width:Number,
            height:Number, color:uint,
            itemRenderer:IListItemRenderer):void {
        if (isRowSelectionMode()) {
            width = unscaledWidth - viewMetrics.left - viewMetrics.right;
        }
        var borderColor:uint = 0xff0000;
        var g:Graphics = Sprite(indicator).graphics;
        g.clear();
        g.beginFill(borderColor);
        g.drawRect(0, 0, width, height);
        g.beginFill(color);
        g.drawRect(1, 1, width - 2, height - 2);
        g.endFill();
        indicator.x = x;
        indicator.y = y;
    }
}
