[Solved] 'Telerik.Windows.Controls.RadDiagram' does not contain a definition for 'ExportToImage'

[Shrikant]

Hi Telerik Team,

In diagram Design Toolbox demo code, I am getting error on ExportToImage Function

Error :  'Telerik.Windows.Controls.RadDiagram' does not contain a definition for 'ExportToImage' and no extension method 'ExportToImage' accepting a first argument of type 'Telerik.Windows.Controls.RadDiagram' could be found (are you missing a using directive or an assembly reference?)

however,This function is not present in Demo Code at user side.
Telerik Version : 2012.1.215.1050

private void ExportToImage(bool isPng)
      {
          SaveFileDialog dialog = new SaveFileDialog();
          if (isPng)
          {
              dialog.DefaultExt = "PNG".ToLower();
              dialog.Filter = string.Format("{1} File (*.{0}) | *.{0}", "PNG".ToLower(), "PNG");
          }
          else
          {
              dialog.DefaultExt = "BMP".ToLower();
              dialog.Filter = string.Format("{1} File (*.{0}) | *.{0}", "BMP".ToLower(), "BMP");
          }

          if (!(bool)dialog.ShowDialog())
              return;

          Stream fileStream = dialog.OpenFile();
          if (isPng)
              this.diagram.ExportToImage(fileStream);
          else
              this.diagram.ExportToImage(fileStream, new BmpBitmapEncoder());

          fileStream.Close();
      }

Hello Shrikant,
The ExportToImage method was added to the RadDiagram with the 2012.1.306 internal build and that's why you're getting this error with older versions (2012.1.215).
If you want to use this functionality you'll have to download a newer version and if you have further questions please feel free to ask.

All the best,
Zarko
