Please help me over this.

Error details as below.
System.ArgumentOutOfRangeException : {"256 is not a valid column index in the current format. The value must be between 0 and 255.\r\nParameter name: columnIndex\r\nActual value was 256."}

Message : 256 is not a valid column index in the current format. The value must be between 0 and 255.
Parameter name: columnIndex
Actual value was 256.

    Hello Vish and thank you for posting!

    From the stack trace it seems that the column with index 256 does not exist and that is why it could not be accessed and exception is thrown. Please note that columns indexes are zero-based and in case there is 256 columns the indexes would be between 0 and 255.
    If you could share a sample project illustrating the issue I can have a look at the specific implementation and try to figure out where exactly the indexes are not correct. You can also have a look at the Samples Browser under XamPivotGrid->Data->Export to Excel sample that shows how the exporting is done.
