how to display null-date as blank space in the ms report (+mssql2008) ?

I have ms report showing data from mssql2008 server
When date-field is null an error message appears
Then I modify "select .... aDate... from.." as "select .... isnull(aDate,'')... from.."
And when date-field is null I get "01.01.1900"
---
so how to show blank when date-field is null ?

Ivanov, please be a little more descriptive as to what you are trying to accomplish.

From what I am gathering so far, you are trying to return data for a microsoft report using a select statement, but are trying to return a empty string or no value if there is a null in a date field?
If this is the case, you need to let the query return whatever its going to return and handle the returned value in the field itself by setting a property. Is the Microsoft reporting services you are using? There are ways of handling returned values within the report itself. Its been a while since I have used this, but I would start by looking at the report designer and properties for the field you are concerned about.

Thank you for response..
I use a c# program with "stumulasoft reports .net" report system (very like MS Report )
Data are in ms sql server2008
In the datasource I use t-sql command "select .....aDate.. from aTable...."
aDate column is date type column
Every record had a value and everything was okay
Yesterday a field had lost its value and it is null
And report started to shows an error message
I have changed the simple t-sql query to "isnull (aDate,'')"
Now everything is ok but null-date field appears to be "01.01.1900"
And I do not know what and when sql=server or report-system does this mystery
I want blank space or empty or something like that..

Ok tomorrow I will check field-properties in the the report-system again
