Gridview wont display data from stored procedure

Asked by garethh86 in .NET Framework 2.0, MS SQL Server, Microsoft Visual Basic.Net

Tags: VB.NET, SQL, ASP.NET

I have a page which allows users to enter details into text boxes and then a gridview to display results based on the entered data. I have a gridview which is supposed to display the returned data.

My stored procedure works fine testing from the sqldatasource but when the button is clicked the grid displays nothing.

Heres the sql statement (which I have tested and returns data ok).

(
      @FirstName NVARCHAR(50),
      @LastName NVARCHAR(50),
      @Email NVARCHAR(50),
      @PostCode NVARCHAR(50)
)

AS

      SELECT * FROM Customers
      WHERE FirstName LIKE @FirstName
      OR LastName LIKE @LastName
      OR EmailAddress LIKE @Email
      OR PostCode LIKE @PostCode

The SqlDataSource works fine, once completing the wizard it allows you to test by entering the variables and it returns the data. The gridview is set to this connector but upon clicking the button the page posts back but the gridview does nto display. I know the gridview wont appear if there is no data to display, where is it going wrong? Is the page posting back to quickly for the SQL server to return the data?

Thanks in advance!
