Copy to clipboard

[Artemis]

Hi.

I want to put a button on the form that would copy the chart to the clipboard, so that I can paste it to MS Office apps.

I know there is an export function, but is there a way to do a copy to clipboard?

Hello Artemis,

Thank you for writing.  

The possible solution that I can suggest is to export RadChartView to an image and set this image to Clipboard. The following help article is quite useful about the export functionality: http://docs.telerik.com/devtools/winforms/chartview/features/export

You can refer to the following stackOverflow thread where it is discussed how to set an image to Clipboard: http://stackoverflow.com/questions/16964152/how-do-i-put-an-image-on-the-clipboard

I hope this information helps. Should you have further questions I would be glad to help.

Hi Dess.

I have been able to export the image to a stream using the following code:

 Dim ms As New System.IO.MemoryStream
 Me.RadChartView1.ExportToImage(ms, Me.RadChartView1.Size, System.Drawing.Imaging.ImageFormat.Jpeg)

However, the code does not work for emf image format.

If I use the code:

 Dim ms As New System.IO.MemoryStream
Me.RadChartView1.ExportToImage(ms, Me.RadChartView1.Size, System.Drawing.Imaging.ImageFormat.Emf)

I get the following error:

System.ArgumentNullException: Value cannot be null.

Parameter name: encoder 

I get the same error when I try to export to file in emf format:

 Me.RadChartView1.ExportToImage(dialog.FileName, Me.RadChartView1.Size, System.Drawing.Imaging.ImageFormat.Emf)

Hello Artemis, 

Thank you for writing back. 

The ExportToImage method tries to save a Bitmap to the specified format. However, it seems that saving emf files should be handled in a different way. Please refer to the following stackOverflow threads:

I have logged it in our feedback portal and I have added a vote for it on your behalf. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is to use one of the other ImageFormats.

I hope this information helps. If you have any additional questions, please let me know.
