No, your question is fine. I was just trying to explain that what you are asking for cannot be answered in a forum like this, as it would take too long. If you read some of the introduction articles on the subject of your choice they will show you how to do the things you want to learn. Then when you find something that you have difficulty understanding, or that does not seem to work, you can post a question and people will try to help.

Assuming you want to use WPF since you asked in this forum...

The entire SDK is available free online, and it also is included
with Visual Studio:

Windows Presentation Foundation[^]

I always recommend reading the entire SDK TWICE, maybe
trying out some code the second time through. It's amazing how few
questions one will have if one knows the fundamentals...

Maybe your first question should have been : How can I find some resource to learn WPF?

This is far too wide a subject to post an answer here. Take a look at some of the WPF articles here on Code Project for further information.

Do you mean 'many' ? You just add them, one at a time. It's no different, no matter how many there are

To communicate between classes, use delegates.

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.

WPF datagrid row mouse double click event

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?

What is a good learning path for WPF?

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?

Re: What is a good learning path for WPF?

Pete O'Hanlon18-Oct-09 3:41

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.

DataGrid displays lengths of strings instead of the actual strings

Nick Alexeev17-Oct-09 17:49

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,

WCF is showing lists as arrays?

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

Re: WCF is showing lists as arrays?

Pete O'Hanlon16-Oct-09 10:12

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());
