Thank you for the sample on how to read the xls file. After I read the file into IWorkbook object, how do I display the data in the grid, so that it looks just like the data in excel file.

Thanks,

Hi,

Thank you for the details.

Please refer to the sample in the link below that uses Syncfusion Essential Grid Silverlight to display the sheet values.

Hi Geetha,
Thanks for the sample on how to read xls file. When I use your sample FindAndExtract.xls file, it opens fine and reads the data, but its not getting the format of the cells (bold font, cell colors..). I see that Range class object has these settings, but I couldn't understand how to pass those format settings to the grid cells.

What I am trying to do is to import an excel file that has all the excel formatting with formulas and display it in the silverlight application. When user enters the data in the cells, it should calculate and update the values of the cells with formulas. I will appreciate if you can send me a sample to do the above.

When I use my own excel file, it throws the following exception with stack trace:

at Syncfusion.CompoundFile.XlsIO.Net.DocumentPropertyCollection.ReadHeader(Stream stream)

Thank you for all the help.

Hi,

Thank you for the details.

Could you please create a direct-trac incident on this regard so that we could check if the problem is with XlsIO or Grid and get back to you accordingly? Also, please send us your input document which would help us to investigate the problem.

Hi Geetha,
I have submitted direct trac for the exception I was getting for my excel file. Meanwhile can you send me a sample to import an excel file that has all the excel formatting with formulas and display it as it is seen in excel using silverlight. The important thing for me is to retain the excel formating and to retain the excel formula in the cells after it is displayed in the silverlight application.

Thank you.
