I'm selecting table data of the current user:
SELECT [ConfidenceLevel], [LoveLevel], [HappinessLevel] FROM [UserData] WHERE ([UserProfileID] = @UserProfileID)
I have set a control to the unique user ID and it is getting the correct value:
HTML: <asp:Label ID="userID" runat="server" Text="Labeluser"></asp:Label>
C#: userID.Text = Membership.GetUser().ProviderUserKey.ToString();
I then use it in the where clause using the Configure Data Source window unique ID = control then controlID userID(fills in .text for me)
I compile and run but nothing shows up where the table should be.
Here is the code it has created:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1">
<Columns>
<asp:BoundField DataField="ConfidenceLevel" HeaderText="ConfidenceLevel"

I have searched the web and discovered bits and peices of information but nothing really in depth that shows me how to fully utilize an (.accdb) Access Database with Visual Web Developer Express Edition. Can someone give me an explanation of how to set up my .aspx page for C#?

Also, under the Defining Parameters, I am setting the ID parameter to Form Parameter Source and have entered the Grid Views name in the Form Field.

I recently started using SSRS 2010 and I didnt come across this issue in 2005 or 2008 versions of reporting services.

View 3 RepliesI have a reportviewer (Microsoft.ReportViewer.WebForms) control on my page. All my reports use one data source. I want to be able to let my reports run on a different database when started from my UAT enviroment. So the location of the reports is the same, but the data comes from a different db. I cannot seem to find how this is done, is it even possible?

View 1 RepliesI know this sounds odd. I have a SQL DB that I am pulling data from. I have to some math functions to get a percentage. So I am pulling all the data in my code and building a data table with the results. I am then trying to pass this into a chart control that I have, but it fails because the data source is not correct for the chart control. I know that the chart control will accept a SQLDataSource control as a data source because a built a example with it before using it in my project.So my question is how can I use the Data Table as a data source for a SQLDataSource Control? Or is there a way I can pull the data from my DB andapply the math needed in a stored procedure or something similar that I could create the procedure on my SQL server then add a SQLDataSource control to my page and use the stored procedure as the source for the SQLDataSource Control.
