Merge SQL to Excel--Need .Net button to open on fly and have current SQL data!

  

           Hello all,
I do not know if this is the proper place to ask this, but my question is...
I have a SQL DB and I want to convert it to Excel Sheet (I did this using the wizard)!
In my aspx page I have a button.  So when I press this button I want the Excel sheet to open!  But I need the Excel sheet to show me the up to date information that is in the SQL DB.  

Automatically set a property value for a new record in a Dynamic Data application.

  

I have a SalesOrderItem table, and it has a UnitPrice column in case the salesperson wishes to override the unit price of the Product for that order item.

In an ASP.NET Dynamic Data application, what would be the best way to set that UnitPrice property on a new SalesOrderItem based on the standard UnitPrice for the product? In other words, when the user clicks New on the 'Items' screen for a sales order, the UnitPrice field should already be filled in with the normal unit price for the product.


This was originally asked by myself on StackOverflow at: http://stackoverflow.com/questions/3538234/automatically-set-a-property-value-for-a-new-record-in-a-dynamic-data-application

Cannot INSERT record using Asp.Net Dynamic Data Domain Service Web Applications

  
 Hi, I am working on a 'Asp.Net Dynamic Data Domain Service Web Application' project using just 2 tables, FAQ_Categories and FAQs. The FAQs table has a foreign key to the FAQ_Categories. The steps are straight forward. Add a new project (Asp.Net Dynamic Data Domain Service Web Applications) Add folders Model ( for Linq2Sql datacontext), Domain (for the Domain Services class) Add Linq2Slql and add the 2 tables to the designer. Build the project. Add the Domain Service Class to the Domain folder. in the wizard select the DataContext, uncheck the Enable Client & Expose ODate checkbox Check bothe table & their corresponding Enable Editing tables checbox Check the Generate Metadata class Click OK. In Global.asax set Scaffold to true and add the DomainService name. Build and run.   Pages List and Detail are working fine. But if I try to insert a new record, I get the error "FaqId is required" Faq_ID is the primary key in the database table and it is set to Identiy. The Datacontext is correct, it marked the FAQ table with <Global.System.Data.Linq.Mapping.ColumnAttribute(Storage:="_CustomerId", AutoSync:=AutoSync.OnInsert, DbType:="Int NOT NULL IDENTITY", IsPrimaryKey:=true, IsDbGenerated:=true)> _   I tried this using Linq2Sql, Entity Framework, And both in VB and C# with the same result. I am using VS20

How to update selected item state in the list box by clicking a button?

  
I created a listbox menu to browse through content by clicking items in the listbox. I also created ‘back’ and ‘forward’ type of navigation to browse through the same content based on the browsing history. I load content into frame and accessing the browsing history with NavigationCommands.BrowseBack and BrowseForward Properties. It is working great. However, I need to indicate a selected state of the listbox item related to the content shown in the frame while browsing with Back/Forward buttons. I have a hard time binding that property. What is the correct way to bind selected state of the listitem in this case? Thank you in advance. XAML: Button <Button x:Name="NavBack" Content="" HorizontalAlignment="Left" Margin="20,0,0,0" Style="{DynamicResource BackButtonStyle}" VerticalAlignment="Top" CommandTarget="{Binding ElementName=ContentFrame}" Command="{x:Static NavigationCommands.BrowseBack}" SnapsToDevicePixels="True" IsEnabled="{Binding CanGoBack, ElementName=ContentFrame, Mode=OneWay}" > XAML: Listsbox <ListBox x:Name="Nav_ListBox" Margin="0,18,0,0" ScrollViewer.HorizontalScrollBarVisibility="Hidden" Background="#FFF2F2F2" ItemsSource="
