What does this have to do with WPF, WCF or WF?

First of all, what you want is not possible. Second, if it was possible, it's plain that you're too dumb to do it. This is the WPF/WCF forum.

How to handle WPF datagrid row double click event? I tried with PreviewMouseClick. But it is getting throwed when clicked on header also.
Private Sub dbGrid_PreviewMouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Input.MouseButtonEventArgs) Handles dbGrid.PreviewMouseDoubleClick
If Not dbGrid.SelectedItem Is Nothing Then
MsgBox(DirectCast(DirectCast(DirectCast(dbGrid.SelectedItem, System.Object), System.Data.DataRowView).Row, System.Data.DataRow).ItemArray(0).ToString)
End If
e.Handled = True
End Sub
How to handle it only for datagrid row?

After I've hacked together my first WPF app today, I'd like to embark on a slightly more formal approach to continuing to learn WPF. What do you guys recommend?

I'd recommend that you knock something up using MVVM. It's a great pattern, and you'll find it helps you a lot later on.

Read all the articles here on The Code Project by Josh Smith & Sacha Barber, particularly their introduction sets. Also take a look at the books they recommend as they are likely to be useful.

I'd recommend getting Pro WPF in C# 2008 by Matthew MacDonald It's well organized, takes you step-by-step through WPF and covers most of it. I still refer to it when I'm coding WPF.

Colleagues,
Familiarizing myself with DataGrid (and with C# in general). My DataGrid is declared like this:
<my:DataGrid AutoGenerateColumns="True" Margin="74,32,68,103" Name="dataGrid1" xmlns:my="http://schemas.microsoft.com/wpf/2008/toolkit" />
I’m setting the ItemSource property equal to a list of strings.
public Window1()
{
InitializeComponent();
List<string> lstGridData = new List<string>();
for (int i = 0; i < 8; ++i) lstGridData.Add("str");
dataGrid1.ItemsSource = lstGridData;
}
I’m expecting that grid would display one column and each line would show “str”. Instead, the grid displays one column titled “Length” and each line displays “3”.
What am I missing?
Cheers,
- Nick

The AutoGenerateColumns mechanism binds to any bindable properties
it finds in the objects in the List.
For a string, that's String.Length.

How can I make a "bindable string"? Is there a framework object with a bindable string property which is commonly used for this purpose? May be, one option is to make a wrapper object with a bindable string property (call it, say, BindableString).
Is there a simple/quick solution to "populate DataGrid with primitive values" problem?
Tried with manually defined columns (AutoGenerateColumns=False). Didn't work either. Looking for a good DataGrid tutorial...
Cheers,
- Nick

Hi
I have built a web service pull data off from one application, which in turn links to another application's web service. However, when I look at one of the data types, which happens to be a list object, Visual Studio shows it as an array.
Can someone please advise me how I can use the meta data to correct this to a list object, or if there is another way to correct this?
Thanks

It returns an array because a web service has nothing to do with Microsoft technologies - they are intended for other platforms as well. This means that you can't return a List return because it's a generic, which isn't allowed in web services. If you really need to use the return type in a generic list, you simply need to add the items in using the following logic:
List<MyObject> list = new List<MyObject>();
list.AddRange(myWebService.WebServiceMethod());

The proxy generator can be configured to return a Collection. In fact it can even be configured to return a custom collection class that is shared between the client proxy and server code.

Hi
Ok, how do you configure the proxy to return a List?
|
|
|
|
|
Use the /ct[^] flag.
/ravi
|
|
|
|
|
...or right-click the service reference in the Solution
Explorer, choose "Configure Service Reference", and
set the collection type.

Well, I tried your solution, but it made no difference. Is there another way to solve this? Is some way in the binding to force the datatype to be a particular type?
Thanks

Make sure all the service references involved are configured the
way you want them and updated (right click service referenc(es) and
choose "Update Service Reference").
If the automatic code generation tool isn't giving you what you
need then you can always hand-code the service interface stuff.

There's even some who would never use a tool to generate
the proxy code for them

I just had a surprise from WPF in that the drawing functions are anti-aliasing (or something similar) my drawing.
Im not doing naything fancy :
....
RenderTargetBitmap renderBitmap = new RenderTargetBitmap (
PixelWidth,
PixelHeight,
DpiX,
DpiY,
PixelFormats.Pbgra32 );
foreach ( DrawingVisual aVisual in visuals )
{
//blah blah, get dc for each visual in my list, draw geomtry to visual
...
renderBitmap.Render ( aVisual );
...
}
Image img = new Image ( );
img.Source = renderBitmap;
///blah blah encode and save stream to file
all the geometries are simple pens of single color, but the final image has been antialiased, edge colors 'smoothed'.
As this is is an imaging app where every pixel value must be specific, I cant tolerate any kind of 'smart' smoothing.
What am I doing wrong wrong ? How can I guarantee that ONLY those colours that I specify will be displayed ? There must be someway to turn off this ant-aliasing.
thanks for your help, any suggestions or alternative would be appreciated.

Have you tried setting the VisualEdgeMode property of your DrawingVisuals
to Aliased (or maybe setting RenderOptions.EdgeMode="Aliased" on your RenderTargetBitmap,
something like RenderOptions.SetEdgeMode(renderBitmap, EdgeMode.Aliased); ?
