    <p>Okay, I've learned a bit more and have rephrased my question. I've got a need to flip or invert text 180 degrees (so it appears upside-down) on a RDLC report. I have some custom VB code that takes the text, converts it to a bitmap, then flips the rotates the canvas 180 degrees. The effect of this makes the text look a bit.. dithered... or fuzzy. It's not a sharp font anymore. The problem I'm experiencing is I'm using a special TTF Barcode font that creates something a scanner can read. When I flip the barcode font, the fuzziness isn't good since the barcode lines are so close together and the scanner cannot read it. Here's the code:</p> <pre><code>Function LoadImage(ByVal sImageText as String, iRotationAngle as Integer, ByVal sFontName as String, iFontSize as Integer) Dim bmpImage As New Drawing.Bitmap(1, 1) Dim iWidth As Integer = 0 Dim iHeight As Integer = 0 '// Create the Font object for the image text drawing. Dim MyFont As New Drawing.Font(sFontName, iFontSize) ', System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point) '// Create a graphics object to measure the text's width and height. Dim MyGraphics As Drawing.Graphics = Drawing.Graphics.FromImage(bmpImage) '// This is where the bitmap size is determined. iWidth = MyGraphics.MeasureString(sImageText, MyFont).Width iHeight = MyGraphics.MeasureString(sImageText, MyFont).Height '// Create the bmpImage again with the correct size for the text and font. bmpImage = New Drawing.Bitmap(bmpImage, New Drawing.Size(iWidth, iHeight)) '// Add the colors to the new bitmap. MyGraphics = Drawing.Graphics.FromImage(bmpImage) MyGraphics.Clear(Drawing.Color.White) MyGraphics.TextRenderingHint = Drawing.Text.TextRenderingHint.ClearTypeGridFit MyGraphics.TranslateTransform(iWidth,iHeight) MyGraphics.RotateTransform(iRotationAngle) MyGraphics.DrawString(sImageText, MyFont, New Drawing.SolidBrush(Drawing.Color.Black), 0, 0) MyGraphics.Flush() Dim stream As IO.MemoryStream = New IO.MemoryStream Dim bitmapBytes As Byte() 'Create bitmap bmpImage.Save(stream, System.Drawing.Imaging.ImageFormat.Bmp) bitmapBytes = stream.ToArray stream.Close() bmpImage.Dispose() Return bitmapBytes End Function </code></pre> <p>I really dont know why there's not a built-in way to just flip text. It'll let me reverse it left-to-right. Ridiculous.</p> <p>Thanks</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
