  Hello!

  I am struggling to bind a byte of an image to the Image control in an RDL Report. The below is what is in the .rdlx:

  <Image Name="imgSignature">													
  			<Height>0.625in</Height>
  			<Left>1.833333in</Left>
  			<MIMEType>image/jpeg</MIMEType>
  			<Sizing>Fit</Sizing>
  			<Source>External</Source>
  			<Style />
  			<Value>=Fields!SignatureField.Value</Value>
  			<Width>3.7917in</Width>
  			<ZIndex>1</ZIndex>
  		</Image>
  

  The rest of the text fields bind fine and I have the appropriate dataset created.

  My C# code is where this gets fuzzy. I use an OnLocateDataSource event to bind the data with the values I want populated in the report. However, i’m unsure what my SignatureField field type should be. Should I be converting my byte to a base64 string? An Image? I swear I’ve tried every possible combination of things and never see the image populated.

  This is a user input image so it will not be embedded nor can I point to a specific location for it.

  Hi Mohit, I’ve tried that too with no success. My biggest confusion of what I should be passing into SignatureField. Should it be a base64 string?

  Hello,

  Byte array should work. I have tested with the AdventureWorks database and it work successfully at my end. Please check the attached report.
  
  If you are still able to reproduce the issue, please share the report with dummy db so that I can look into the issue and help you further.

  Thanks,
  
  Mohit
