How do I work with WIndows Forms in WPF?
In my WPF program I created a Windows Form class.
In this Form, I placed an OK button and I went into the properties of the button and set the DialogResult to OK.
Now, I am calling this Dialog (Window Form) from the MainWindow.xaml.cs:
DialogResult dres;
dres = form.ShowDialog();
if (dres != DialogResult.OK) return;[/code]
The compiler is complaining:
Error 3 'System.Nullable<bool>' does not contain a definition for 'OK' and no extension method 'OK'
accepting a first argument of type 'System.Nullable<bool>' could be found (are you missing a using directive
or an assembly reference?)

WinForms uses its own version of DialogResult. You need to add a reference to Windows Forms to your project and then reference the OK as System.Windows.Forms.DialogResult.OK.

Is it possible to subclass a Window in WPF, so that I can create a base Window class? If so, how?
Everything makes sense in someone's mind

Hi Kevin,
Create your CustomWindow derived from Window and if you want, you can create the Template for your new Window and assign to it. Let me know if you need more help on it.

I'd like to see an example of that, if you have one.

Hi,
Have a look into this blog post for Silverlight: Creating a Custom Out-Of-Browser Window in Silverlight[^]
There are some good example for WPF too. I will share those links if I recall the URLs from my bookmark.
Till then check for the Silverlight one. You will get the basic understanding from the same.
Let me know, if you have any queries.

This may be a trivial question but I'm completely new to Silverlight and right now I just want to know if I can embed a Silverlight control in my "classic" AST.NET (3.5) WebForm page?
Googled for samples but no result.

You cannot embed silverlight control individually.
You need to generate .xap file from the silverlight page/control
and then you can easily embed it in aspx page as an object.
Find following code to embed .xap file.
<div id="silverlightControlHost">
<object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">
<param name="source" value="ClientBin/SLNetWCF.xap"/>
<param name="onError" value="onSilverlightError" />
<param name="background" value="white" />
<param name="minRuntimeVersion" value="3.0.40624.0" />
<param name="autoUpgrade" value="true" />
<a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40624.0" style="text-decoration:none">
<img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style:none"/>
</a>
</object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div>

You cannot do this and that is why you found no results.
As is posted in the other answer, you can embed your xap control inside the page.
You can probably search for some controls for Asp.net which do something similar to what you are using in Silverlight.

<chartingToolkit:PieSeries <br />
IndependentValueBinding="{Binding ItemKey}" <br />
DependentValueBinding="{Binding ItemValue}"<br />
AnimationSequence="Simultaneous"<br />
IsSelectionEnabled = "true">
Thanks,

Is it possible to bind multiple values to a single component in XAML?
I want to put two values into a single TextBlock with one binding attribute. Possible?

You could do this with the MultiValueConverter available here[^].

Thanks. I'll look at that at home in the next couple of days (this is for a WPF front-end to my CP article scraping library).

The convert thing won't work for what I need. I just created additional properties that provide the needed data and bound to those instead.

Hi,
Did you ever figure this out.
I am trying to do the same thing where if I am binding a property called Score to my WPF data grid, I need the value of it to be reflected when one of the dependency properties changes....
for instance:
Class A : INotifyPropertyChanged
property Score
Class B : INotifyPropertyChanged
property Score (this property value should be dependent on the composition of two ClassA.Score values and should display in the same column that is bound to Score in the Data Grid.
Kindly let me know if you found a solution.
Thanks

This should be easy but I can't get to work. I just want to set the value of a textbox when the select value in a list box changes.
Here's how it works in a combobox.
Category.Text = ComboBox1.Text
How does it work in a list box in vb.2010 (WPF)?
|
|
|
|

Have a look here.
The equivalent of Category.Text = ComboBox1.Text is a little different in WPF.
You need to link the CurrentItem of a listbox to your textbox.
The link above might give you a better idea.

Thats good info, but I really do not want to databind that textbox. I'm binding back to SQl already I just want to give the user an easy way to populate/change the field value. The combo works, but a list box looks much better. I'm making it visilble from a click event.
Thanhks for the info.

Hi,
you must convert the SelectedItem of the ListBox into the string you need. You can do this by binding it to another property (of your viewmodel) and in the new property's setter, you can transfer the converted string-value to your TextBox.Text-property. Alternatively you must code the SelectionChanged-event of the ListBox.
The type of the SelectedItem depends on the given Items (sounds a bit stupid, I know). If you fill the ListBox at designtime, you will probably have something like
<ListBox ... >
<ListBox.Items>
<ListBoxItem Content="one" />
<ListBoxItem Content="two" />
<ListBoxItem Content="three" />
</ListBox.Items>
</ListBox>
In this case, the SelectedItem is of type ListBoxItem. If you e. g. provide a List<string> as ItemsSource, you get a string as SelectedItem.
As mentioned by Abhinav S you might want to consider using the IsSynchronizedWithCurrentItem property.
Cheers
Jürgen

Hi All,
Hope you all are good.
I am adding some wrap panels to a list box..
my coding is
for (int i = 0; i < 15; i++)
{
WrapPanel wrp = new WrapPanel();
wrp.Name = "wrp" + i.ToString().Trim();
Label lbl1 = new Label();
lbl1.Content = "Code " + i.ToString().Trim();
Label lbl2 = new Label();
lbl2.Content = "Desc " + i.ToString().Trim();
wrp.Children.Add(lbl1);
wrp.Children.Add(lbl2);
lbOne.Items.Add(wrp); //lbone is source list box
}
so now i have 15 wrap panels in my lisbox.
i need to add the selected items(wrappanel) to other list box (may be destination)
i tried using
lbtwo.items.add(lbone.selecteditem);
but it says that it has some logical parent.
i.e it is already in the first list box lbone and it cannot be added to the new one..
may i know is there solution for this?
can we add liek this?

There is, and it's a bit gnarly. The good Dr WPF came up with a Conceptual Children article which details how to solve this issue here[^].
