hello,

I have the same probleme since monday...
I'm looking for filtering my SQL's columns user field from the current windows's userid .

I followed some explaination but nothing works i let you see my code:

in my ASP page I would test with a short query:

<asp:sqldatasource id="SqlDataSource1" runat="server" connectionstring="<%$ ConnectionStrings:LabAccManConnectionString %>"
    selectcommand="SELECT * FROM [account_user] WHERE [genacc_user_adacc] = @genacc_user_adacc">
    <selectparameters>
        <asp:parameter name="genacc_user_adacc" type="String" />
    </selectparameters>
</asp:sqldatasource>

when i put 'hermans5' instead of @genacc_user_adacc it works it displays one line properly into my grid view

may be it come from the "code behind":

Imports System.Text.RegularExpressions
Imports System


Partial Class userpage
    Inherits System.Web.UI.Page
    Protected Sub SqlDataSource1_Selecting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs) Handles SqlDataSource1.Selecting
        e.Command.Parameters("@genacc_user_adacc").Value = Me.User.Identity.Name
    End Sub
End Class

Thanks you in advance, this problem makes me crazy it don't understand at all :(

Thanks

Best Regards


Samuel
