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[^].

I have completed an application that looks boring. I can add graphics to my WPF based GUI but what I would like to do is change the entire shape of the GUI itself. The best example I can think of is that of changing skins on a media player... by changing the skins you can change the overall shape of the GUI as well as the placement of the controls. One skin may be an 800 pound guerrilla while another might be a hamburger. I would be able to change it with the click of a button. I can easily place a picture of a guerrilla into my WPF based GUI and place the controls on it but the GUI itself that contains the guerrilla picture still has four straight sides.... I want my GUI to morph into the shape of the primate.
Can someone point me in the right direction?
And to complicate things.... Another idea we have is to place controls on each of the six sides of a cube. Once we have the GUI assume the shape of the cube we would like the user to be able to use their mouse and spin the cube around by clicking and dragging....thus accessing the controls on the other sides. And could we do all that using finger input on a touch sensitive screen? ...
Can someone point me in the right direction on that idea?
Thanks,
Jay

Hi
I have a Silverlight application calling a WCF service. SimplehttpBinding stuff.
1. Every I make changes to silverlight xaml code, the web.config gets refrshed also.
2. Even if make any changes to web.cofig file, they get overwritten too.
Its as if, some other process is writing these files. Why is that happening? How can I make sure that it does not get overwritten after every compile?
Please advise. THanks
AJ.

Which version of Visual Studio you are using there?
Is it only for Silverlight application?
Can you try with a New Project (both Silverlight & ASsP.Net web app)?

I am writing my first WPF program for learning purpose. I discovered there is no FolderBrowserDialog. With some search I figured we are supposed to use Microsoft.Win32.OpenFileDialog. Now, I really do not want to use it. So I tried using FolderBrowerDialog through adding reference to the Windows Form dll. Now, when I try the following code, DialogResult is treated as some nullable type (although intellisense shows it as Enum).
if(dlgFolderBrowser.ShowDialog() == DialogResult.(only nullable type options come up))
Any idea how this can be fixed? Or any better solution than using a OpenFileDialog with multiple select option?

Found this here -
System.Windows.Controls.PrintDialog dlg = new System.Windows.Controls.PrintDialog();
dlg.PageRangeSelection = PageRangeSelection.AllPages;
dlg.UserPageRangeEnabled = true;
Nullable<bool> result = dlg.ShowDialog();
if (result == true)
{
}
This link, I guess, should give you a solution.

Does not works with System.Windows.Forms.FolderBrowserDialog. Its return type is DialogResult and not Nullable.
|
|
|
|
|
this.DialogResult is a property on WPF windows, unrelated to the enum you are looking for. Try to use the fully qualified type name.

Great! Thanks. I feel stupid to not to be able to figure that out.
BTW, is that a good way? I am not a fan of mixing technologies: WPF and Windows forms in this case.

There is no List document element in Silverlight 4. So how do you format an itemized list in a RichTextBox? Is there any easy way?

KunalChowdhury wrote: What do you mean by itemized list in a RichTextBox?
I don't understand your question. Surely you aren't asking me what an itemized list is, are you?
It doesn't matter anyhow. There is no way to do it. I just expected it to be there since the new RichTextBox in Silverlight 4 takes a list of something called Paragraph elements and I just naturally assumed these were the same Paragraph elements that were in WPF, which do take itemized lists. But they only vaguely resemble the WPF Paragraph. They don't even have a Margin property which might be a starting point for rolling your own itemized lists.
So forget it. I learned from a recent Code Camp I went to that Microsoft has given up the idea of ever supporting flow documents in Silverlight. Instead in a future release of Silverlight they will provide a way of supporting an HTML area within Silverlight content. (They've always supported the opposite: Silverlight content within HTML.) Once that happens, we'll be able to include itemized lists within Silverlight and the user won't even know or care that it's actually HTML that is generating the itemized list.
I guess Microsoft figured it was easier to rely on existing technology rather than reinventing the wheel. Trouble is, they should have done this ages ago. Meanwhile, we have to wait and wait, and in the meantime put up with poorly formatted running text in Silverlight applications.
The syntax for itemized lists in WPF is incredibly verbose anyhow. It will be a blessing to be able to use the concise syntax of HTML for generating itemized lists, and flow documents in general. The only thing is, it will never have the convenience of automatically flowing into multiple columns like WPF, although I am by no means an HTML programmer, so maybe that will be possible, also.
