The problem happens with the RadFilter RadNumericTextBox.
If I apply a filter that doesn't contain any numerictextbox, the grid exports fine to excel.
I need to fix this problem urgently. Please help.
Can this be a bug or an issue on RadNumericTextBox PreRender?

I finally figured out whats going on.
There are problems between RadNumericInput and ExcelML format.
If export format is set to ExcelML in export settings the exception ocurrs.

Hi,
I have HtmlEncoded the data before saving it in DB, now when I exporting the data to file, the encoded data is showen.
How can I Html decode the data before exporting it to file?
Do I need to decode first? Or there is some other way to export the file as the browser display it?

Hello Mozilla,
One possible solution is to provide the data as raw, not encoded string. RadGrid bound column has property HtmlEncode which will ensure that the data will be shown properly.
Other options if the data is already encoded is to modify the content of the cell of RadGrid before export.
