Filtering Dataview <Strange Problem>

Abstract: I want to filter a dataview with a value where column name have a SPACE.

Description:-
I bind a dataview to a datagrid,
The query which is fetching the results in Dataset is something like this:-

Select POSTAL_ADDRESS as "Postal Address" from Emp where ....

Now the column name in Dataview is "Postal Address" which is having a space, with this column name when I am filtering the Dataview like:-

DataViewAddress.RowFilter =  "Postal Address LIKE '*Bel1*'"

which throws following exception:-
System.Data.SyntaxErrorException: Syntax error: Missing operand after 'Address' operator.

I tried
DataViewAddress.RowFilter =  "\"Postal Address\" LIKE '*TyreBel1*'"
I also tried the EncodedColumnName which replaces spaces with _x0020_
like:
DataViewAddress.RowFilter =  "Postal_x0020_ Address LIKE '*TyreBel1*'" but nothing worked and got the same exception every time..
 

I searched the net but I didnt get anything on it...
Any help will be Very-Much Helpful..

Thanks and Regards,
