In my Silverlight application we have to update the data to Predefined excel template and then export the data.
But our predefined template is having company logo. Which is not appearing in excel when we export the file.

Steps to achieve  the Export in Silverlight.

1) we  load the excel using Infragistics excel and then update the data to excel.

2) Then save the worksheet into memory stream and then convert the memorystream into byte array and pass it into service layer and save the Byte array as excel file in server.

3) When you click on export button then pass the path of the file and export it using response object.



Note :- If I just load the Excel template and save the worksheet
into memorystream. convert the memorystream into byte array and pass it into service layer.
Even then image is not appeared in the excel.

Please let me know the solutions.
