How to limit the length column in sql server reporting services -

-

i have table , of cells contain lot of data. want truncate after 10 characters. in design view right clicked column , clicked text box properties unchecked allow height increase. checked preview , fixed problem, after deployed report reporting server length of column increased again. please help.

three methods use:

sql query

in sql query, truncate column so:

select left(foo,10)

calculated field

in dataset, truncate field new column using expression:

=left(fields!foo, 10)

textbox field

the same method applies above in textbox:

=left(fields!foo, 10)
