ASP.NET 4 Visual Studio 2010. Membership Website Question
Posted on 2011-03-09
I have a asp.net 4 membership web with roles. When a user goes to change his password, I want to display that particular users Password Questiion. I added a dataset form view to the membership database and am able to achieve this by a sql query when I specify the users actual name in the query. I want to change my code to query the databased based on the user that is logged in.
Basically I want to change the part in my code that says
WHERE (aspnet_Users.UserName = 'RICK')
to something like
Where aspnet_users.username = (the currently logged in user)
I am not sure what to replace "the logged in user" with to make it equal the currently logged in user
any help would be appreciated.

SELECT aspnet_Membership.PasswordQuestion, aspnet_Membership.PasswordAnswer FROM aspnet_Membership INNER JOIN aspnet_Users ON aspnet_Membership.UserId = aspnet_Users.UserId WHERE (aspnet_Users.UserName = 'RICK')

Are you using inline SQL or calling a stored procedure? If it is inline you would do something like (assuming C#):
string username = Membership.GetUser().UserName;
string sql = string.Format("SELECT aspnet_Membership.PasswordQuestion, aspnet_Membership.PasswordAnswer FROM aspnet_Membership INNER JOIN aspnet_Users ON aspnet_Membership.UserId = aspnet_Users.UserId WHERE (aspnet_Users.UserName = '{0}')
", username);
In that case:
Dim username As String = Membership.GetUser().UserName
Dim sql As String = String.Format("SELECT aspnet_Membership.PasswordQuestion, aspnet_Membership.PasswordAnswer FROM aspnet_Membership INNER JOIN aspnet_Users ON aspnet_Membership.UserId = aspnet_Users.UserId WHERE (aspnet_Users.UserName = '{0}')
", username)
Ok, I will give it a try. Do I just paste the code into in the "define custum sql or stored procedure"?
I added a list view, then made a connection string to the membership database. Then I am at the part where I am creating the custom sql query to return the question. Thank you so much
Ah, ok, that sounds like you are using a SqlDataSource, which means you need to massage things a little to get it to work. In the dialog choose "Custom sql query...." then for the "select statement" paste your SQL statement as:
SELECT aspnet_Membership.PasswordQuestion, aspnet_Membership.PasswordAnswer FROM aspnet_Membership INNER JOIN aspnet_Users ON aspnet_Membership.UserId = aspnet_Users.UserId WHERE aspnet_Users.UserName = @UserName
<asp:SqlDataSource ID="SqlDataSource1" runat="server" OnSelecting="SqlDataSource1_Selecting"
SelectCommand="SELECT aspnet_Membership.PasswordQuestion, aspnet_Membership.PasswordAnswer FROM aspnet_Membership INNER JOIN aspnet_Users ON aspnet_Membership.UserId = aspnet_Users.UserId WHERE aspnet_Users.UserName = @UserName">
<SelectParameters>
<asp:Parameter Name="UserName" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
Protected Sub SqlDataSource1_Selecting(sender As Object, e As SqlDataSourceSelectingEventArgs)
SqlDataSource1.SelectParameters("UserName").DefaultValue = Membership.GetUser().UserName
End Sub
OK. When I put the first code in, it takes me to another screen that says it recognizes I have a parameter "username" It is asking me for a parameter source, a query string fiels and a default value
Ah, it's a little smarter than I gave it credit for :) Leave the source set to "None" and the default value empty, unless you want to give it a default.
