    This question may belong in a different WinForms controls forum. If so, I apologize.

    Ultimately, I am wanting to show a carousel full of RadGridViews, but for performance's sake I am converting the RadGridView's into RadImageItems to be loaded into the carousel.

    I'd like to be able to put a label above the RadGridView as a title for the grid. So far I've tried adding a RadLabel and RadGridView to a RadItemsContainer, and then using the "GetAsBitmap" function to no avail.  

    RadImageItem image1 = new RadImageItem();
    image1.Image = rl.RootElement.GetAsBitmap(Brushes.White, 0, new SizeF(1, 1));
    rl.RootElement.GetAsBitmap(Brushes.White, 0, new SizeF(1, 1));
     
    RadImageItem image2 = new RadImageItem();
    image2.Image = grid.RootElement.GetAsBitmap(Brushes.White, 0, new SizeF(1, 1));
     
    RadItemsContainer ric = new RadItemsContainer();
    ric.Items.Add(image1);
    ric.Items.Add(image2);
     
    RadImageItem image3 = new RadImageItem();
    image3.Image = ric.GetAsBitmap(Brushes.White, 0, new SizeF(1, 1));
    image3.ImageKey = imageKey;

    (rl = previously declared RadLabel, grid = previously declared RadGridView)

    Thanks,

    Rob

    Hello Rob,

    Thank you for the question.

    We have never tested such a scenario before, but I would like to suggest that you to put a RadGridView and RadLabel into a Panel and call Panel.GetAsBitmap method.

    Another possible solution is to try to combine two bitmaps - paint objects on different layers - here is an interesting article on how to do this.

    I hope this helps.

    Hey Peter,

    Thanks for your response.

    In case anyone ever has this same issue I was able to solve my problem by creating a bitmap of both the RadGridView and RadLabel, adding the images to a new Bitmap object, and then setting the RadImageItem's Image property to the new Bitmap.

    //Previously instantiated grid
    grid.BeginInit();
    grid.BindingContext = new BindingContext();
    grid.EndInit();
    grid.LoadElementTree();
     
    RadLabel descriptionLabel = new RadLabel();
    descriptionLabel.Text = "Success!";
    descriptionLabel.LoadElementTree();
        
    Bitmap gridBitmap = grid.RootElement.GetAsBitmap(Brushes.White, 0, new SizeF(1, 1));
    Bitmap labelBitmap = descriptionLabel.RootElement.GetAsBitmap(Brushes.White, 0, new SizeF(1, 1));
     
    Bitmap bmp = new Bitmap(x, y, System.Drawing.Imaging.PixelFormat.Format32bppArgb);
     
    using (Graphics grfx = Graphics.FromImage(bmp))
    {
       grfx.DrawImage(labelBitmap, 0, 0);
       grfx.DrawImage(gridBitmap, 0, 15);
    }
           
    RadImageItem image = new RadImageItem();
    image.Image = bmp;

    Thanks again,

    Rob
