Making spreadsheet,column/rows as ready only

[Manikandan]

Hi,
I'm using office web components11 for my c# application.
I'm creating a excel spread sheet with data's programmatically.
I have written codes for double click event handler.
if the data in cell is in edit mode means(whole data selected while
doubleclicking sometimes), double click event handler
won't work.
I tried the properties like locked,editmode, protection , all gives
error in compilation itself.
I would like to make whole sheet as readonly, or each columns/rows to
read only.
Is there any method/property available to make columns/rows as
readonly in spreadsheet?

Thanks,
Mani
