Hi
I'm using a typed dataset in my WPF app which was generated for me by adding a new data source via the visual studio wizard. My problem is, when I call the WriteXml
method on my dataset (e.g. dsDemo.WriteXml) it creates an XML file yes, but the only thing in the XML file is the following:
<?xml version="1.0" standalone="yes" ?>
<_Workstation_aXYZDataSet xmlns="http://tempuri.org/_Workstation_aXYZDataSet.xsd" />
Why does it not show all my table data?

This question has absolutely nothing to do with WPF, and you've cross posted in the C# forum. Please don't do this - it's really bad form.

There is no NumericUpDown control for WPF inherently available (as far as I know). But you can always use the Winform NumericUpDown control (using a WindowsFormsHost[^]).
Take a look at this sample on MSDN[^].

I developed a UserControl for a spinner composed of an edit box and a vertical scroll bar. To make it general enough required 400 lines of code but it has proved to be so useful that I've employed it in dozens of different places in my application and it has given me enormous payback. So just read a book explaining how to develop your own UserControl. Knowing how to do this should be knowledge at the fingertips of every WPF programmer anyhow. It's simply part of being a WPF programmer and Microsoft is right about not supplying dozens of little gizmos that would be "nice to have" when the framework itself has been so carefully designed for developers to "roll their own."

Hi
I know probably should've posted this on the XML message boards, but no one seems to reply there.
I have a database with 3 tables; Customers, Orders, and Order Details. The relationships between the tables are set up correctly; A Customer can have many Orders and a Order can have many Order Details. I added this database via the 'Add New Data Source' wizard om Visual Studio. I then use the following line of code to create an XML document from the dataset (dsNWind2k):
dsNWind2k.Customers.WriteXml("path\\asd.xml", true);
The 'true' is for 'writeHierarchy' which specifies that it will convert the Customers table to XML as well as all it's decendants. Now this is exactly what it does, except it doesn't give me a hierarchical xml structure the way I want it to. Instead, it converts all the fields in the Customers table to XML, then directly underneath that it generates the Orders. and once again underneath the Orders, the Order Details.
Is there a way to have it generate all the Customers, then within each Customer it should display the Orders associated with that specific Customer, and then within each Order it should display the Order Details associated with that specific Order.
Here's a sample of what it does at the moment:
..more customers..<br />
..more customers..<br />
<Customers><br />
<CustomerID>NORTS</CustomerID> <br />
<CompanyName>North/South</CompanyName> <br />
<ContactName>Simon Crowther</ContactName> <br />
<ContactTitle>Sales Associate</ContactTitle> <br />
<Address>South House 300 Queensbridge</Address> <br />
<City>London</City> <br />
<PostalCode>SW7 1RZ</PostalCode> <br />
<Country>UK</Country> <br />
<Phone>(171) 555-7733</Phone> <br />
<Fax>(171) 555-2530</Fax> <br />
</Customers><br />
..more customers..<br />
..more customers..<br />
<br />
..more orders..<br />
..more orders..<br />
<Orders><br />
<OrderID>10614</OrderID> <br />
<CustomerID>BLAUS</CustomerID> <br />
<EmployeeID>8</EmployeeID> <br />
<OrderDate>1995-08-29T00:00:00+02:00</OrderDate> <br />
<RequiredDate>1995-09-26T00:00:00+02:00</RequiredDate> <br />
<ShippedDate>1995-09-01T00:00:00+02:00</ShippedDate> <br />
<ShipVia>3</ShipVia> <br />
<Freight>1.93</Freight> <br />
<ShipName>Blauer See Delikatessen</ShipName> <br />
<ShipAddress>Forsterstr. 57</ShipAddress> <br />
<ShipCity>Mannheim</ShipCity> <br />
<ShipPostalCode>68306</ShipPostalCode> <br />
<ShipCountry>Germany</ShipCountry> <br />
</Orders><br />
..more orders..<br />
..more orders..<br />
<br />
..more order details..<br />
..more order details..<br />
<Order_x0020_Details><br />
<OrderID>10599</OrderID> <br />
<ProductID>62</ProductID> <br />
<UnitPrice>49.3</UnitPrice> <br />
<Quantity>10</Quantity> <br />
<Discount>0</Discount> <br />
</Order_x0020_Details><br />
..more order details..<br />
..more order details..
This becomes a problem when I want to bind this XML to my TreeView in WPF, because now Orders and Order Details will become Parent nodes, BUT I want it to be displayed as child nodes underneath Customers
Hope someone can help me

Take a look at the XmlDataDocument class instead of using DataSet.WriteXml()

Hi,
I am new to silverlight, and have a little problem!
I basically want to have a button and a textbox, and when the user presses the button it links to google and does a search on the text in the text box, so it calls
"www.google.co.uk/search?q=" + TextBoxText
The problem is when i put somthing like c# in the textbox, the # gets ignored.

The problem here is that your querystring text is actually malformed. C# is actually c%23 as far as a querystring goes. What you need to do is UrlEncode the text - you can use HttpUtility.UrlEncode(TextBoxText); to encode it (needs a reference to System.Web).

Hi,
I am working on a WPF application. In this I have to set scrolling property for canvas.
If any one have any idea how to do this please reply me.
Thanks in advance.

Are you sure you really want to do this for a Canvas? Inherently, a Canvas has no layout characteristics and it sounds like you're laying yourself open to a whole world of hurt here. Could you not use a Grid and set the Margins of the objects on the grid as appropriate? For instance:
<ScrollViewer HorizontalScrollBarVisibility="Auto">
<Grid Background="Green">
<!-- Layout items here as appropriate -->
</Grid>
</ScrollViewer>

If scrolling is required, I would think a properly oriented StackPanel would be better than a Grid.

Who said the 3rd?
Maybe if I change the 3 to 3.0 it would have been easier for

Maybe if I hadn't just rolled out of bed when I read the post I might have picked up on this. I really need to start getting more than 4 hours sleep.

I added a wpf app to an existing solution, and without changing ANYTHING, I compiled it and tried to run it. I'm getting an error stating that the EXE file can't be found. Does anyone know what the hell I did to make this happen?
----------
I recreated the solution from scratch, and that seems to be the only way I could fix it. What a crock. During the discovery and resolution process, the IDE displayed an invisible modal dialog and refused to let me do anything - including closing the IDE - because the (invisible) dialog was waiting for input. I had to use task manager to close the IDE.
I hate Microsoft.

I have a RichTextBox in my app, which is inside a control that is composed of a grid with 2 columnds,
i.e.
<Grid x:Name="LayoutRoot"
VerticalAlignment="Top" Height="Auto">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="150"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Border x:Name="bdrLeft" Height="Auto"
Background="{DynamicResource SplitRichTextBoxRightSideBGBrush}"
BorderBrush="{DynamicResource SplitRichTextBoxRightSideBorderBrush}"
BorderThickness="1,1,0,1"
CornerRadius="3,0,0,3"
VerticalAlignment="Stretch">
<ContentPresenter x:Name="cpRightSide"
VerticalAlignment="Stretch"
HorizontalAlignment="Stretch"
Margin="0,0,0,0"
Width="Auto"
Height="Auto"
TextElement.Foreground="{DynamicResource SplitRichTextBoxLeftSideForegroundBrush}"/>
</Border>
<Border x:Name="bdrRight"
Height="Auto"
Grid.Column="1"
Background="{DynamicResource TextBoxBGBrush}"
BorderBrush="{DynamicResource TextBoxBorderBrush}"
BorderThickness="1,1,1,1"
CornerRadius="0,3,3,0"/>
<RichTextBox x:Name="rtbMain"
HorizontalAlignment="Center"
FontSize="{DynamicResource DefaultFontSize}"
Height="Auto"
BorderBrush="Transparent"
Background="Transparent"
Foreground="{DynamicResource DEFAULT_Font_Dark}"
VerticalAlignment="Center"
AcceptsReturn="False"
AcceptsTab="False"
Style="{DynamicResource ClearRichTextBoxStyle}"
Grid.Column="1"
Margin="0,3,0,3">
<localControl:EnabledFlowDocument x:Name="efdMainDocument" PageWidth="{Binding ElementName=rtbMain, Path=ActualWidth}"/>
</RichTextBox>
</Grid>
All the animations in the code are set to 00:00:00.00
However, when I add a UIElement or even text to the FlowDocument on startup, the text/uielement appear in the center of the flowdocument, then animate over to the left side where they should be. Is this a bug in WPF? I can't find anything in my code that would cause this.

Fixed:
Set the RichTextBox HorizontalAlignment to Stretch

Hi
Is there a way to populate a treeview using XML in WPF? Or by using the .xsd file?
If yes, please give me advice on how to get started. I've tried binding the treeview to the database using Hierarchical Datatemplates etc. but that still does not do the trick if you want multiple children nodes.
