I have a Visual Studio Form Called Form1

It is conencted to the Query_BuilderDataSet1  which retrive data from a Table tbl_Resources

On the Form1 i have the Grid from the Data set   with contains the collumn ID_Resource , Name , Region, Town , Employer

From the Table adpter tbl_ResourceTableAdpter i have Open the Query Bulder  and design a Query : SELECT ID_Resources , Name , Region , Town , Employer
FROM tbl_Resources
WHERE (Region=@Region OR @Region IS NULL ) AND (Emplyer =@Employer OR @Employer IS NULL )

For example i have inserted IS NULL thinking to have the possibility to Optionally insert only one of the 2 Parameters

But it is Not Working ,

When i Go on the Form1 and  Fill only one of the 2 Text Box  created by the VS designer

the Return into the Grid on Form1 is an Empty Grid

Any one that can help to write the SQL code or the Visual Basic code  behing the Form1 to handle the Opition to have declared only 1 of the 2 Crtieria

For Clarity i have also u Button that  on Click will remove the Query and will show again all the records

Thanks fro Help
