Hi,
I am writing WPF custom control. My problem is I want to do some updations in the control when the control is being creted by copy paste( CTRL+C, CTRL+V) on the cider.
How can I track this event or attch an handler to this event.
Does ApplicationCommand.copy.... make any sense here.
Please help.
Thanks in Advance,
Vinod

You mean when it gets added to a form in the designer ? I'm not sure how you write event code in your control, for an event that fires in another program, but I suspect if it can be done, it will be an actual event that's called by the IDE, OR the constructor is called and you can write a block of code that detects if you're in the designer ( this can be done in Winforms, for sure )

You'll need to write a designer for your control. This is not trival.
You can search for WPF control designer for examples.
There is also documentation on MDSN.

Hi,
I am working on a WPF application. In this we will change the position of the components on the canvas. Every time we change the positions of the components on the canvas, we have to display a thumbnails of the canvas.
I have a procedure to create the images of the canvas.
http://blogs.msdn.com/saveenr/archive/2008/09/18/wpf-xaml-saving-a-window-or-canvas-as-a-png-bitmap.aspx
Now I have to display the images of the thumbnail as canvas dynamically as thumbnails.
If anyone have any idea to solve this please reply me.
Thanks in Advance

Hi,
In WPF, I can set Image with a photo, and can see when I load the page. However, if I want to set that through a code-behind, I cannot. Here is my code, do you find anything wrong in it that might cause this problem? I checked on compile time, and there is no problem in the location of myPhoto.png.
> string location = @"C:\myPhoto.png";
> Uri uri= new Uri(location,> UriKind.Relative);
> ImageSource imgSource = new BitmapImage(uri);
> Icons.Source = imgSource;
> Icons.Width = 10;
>Icons.Height = 10;
> Icons.Visibility = Visibility.Visible;
thanks,

Maybe try
C:/myPhoto.png
Or
File://C:/myPhoto.png
The UriKind should be Absolute as well.

When I made that mistake, I remember getting a compiler error. I was using "/AssemblyName;component/Images/filename.png", and still had to use Absolute.

That's an absolute address though, isn't it?

I wouldn't think so. I would think an absolute address would be a fully qualified path, and the one I use would be relative to the named assembly.
I guess it's a matter of perception.

That's an absolute path, not a relative one.

Hi. I am trying to apply drawing brushes on a 3D model (cube) in Blend. What happened is that I managed to apply my drawing brushes on two opposite sides of the cube, but when trying to apply my brushes to the other sides they simply disappear.
Is anyone there came across this problem and what is the solution?
Thanks,
David

I have spent a few days looking now, and have had no luck, but i thought i would ask here incase any one else knew something i have missed. Is it possible to interact with msOffice applications through a silverlight website.
I'm looking for the ability to create word and or excel documents programatically then launch them in word or excel. Infragistics have a component that lets you import/export data from excel, as do several other component providers, but i have not yet seen any tutorials/documentation on how this is done, any help or pointers would be appreciated.

I take it the answer will be the same for intergrating with outlook too, which is a lot harder to do using web services/applications as they would need to be hosted on the PC viewing the site. The office stuff may be acceptable server side but any outlook interaction would have to be client side.

Silverlight is a browser plugin so it's pretty limited - no playing outside the

Just send a web service request to the server with your parameters for the word/excel file, have the server create the file. The web request can bring back a temporary URL with the desired file that you would link to in a popup window.

Hi
Here's another simple question. I'm a newbie to WPF and I want to bind some data to a combobox. The data is coming from a Typed Dataset which I added via the VS2008 wizard.
Firslty, I instantiate the DataAdapter and the DataTable:
dsParrys_offoice_furnitureTableAdapters.ProductRangeTableAdapter daProductRange;
dsParrys_offoice_furniture.ProductRangeDataTable dtProductRange;
Then I fill the DataTable dtProductRange:
daProductRange = new aXYZ.dsParrys_offoice_furnitureTableAdapters.ProductRangeTableAdapter();
dtProductRange = daProductRange.GetData();
this.DataContext = dtProductRange;
I then want to display all the ProductRangeDescription in the listbox so I do the following:
cboStartupNew.ItemsSource = dtProductRange;
cboStartupNew.DisplayMemberPath = dtProductRange.Columns[1].ToString();
cboStartupNew.SelectedValuePath = dtProductRange.Columns[0].ToString();
cboStartupNew.SelectedValue = dtProductRange.Columns["ProductRangeDesc"];
When I enter debug mode and hover my mouse over cboStartupNew (tho combobox) it says that there are 17 items in the combobox, but still nothing displays in the combobox. Any ideas?
I tried using cboStartupNew.ItemsSource = ((IListSource)dtProductRange).GetList() as wellm but still no luck

What does your data template look like? There are much easier ways to display things in WPF, and it looks as though you are trying to use ASP.NET techniques rather than using the power of binding and templating in WPF.

I'm not using a DataTemplate. I was under the impression that the binding will work even without one.

Hi,
I am working on a WPF application. In this I have a listview as
<ListView Height="271" HorizontalAlignment="Right" Margin="0,52,12,0" Name="lstvHistory" VerticalAlignment="Top" Width="181">
<ListView.View>
<GridView >
<GridViewColumn Header="Type" Width="50" />
<GridViewColumn Header="Description" Width="130"/>
</GridView>
</ListView.View>
</ListView>
In this dynamically I have to add one row at a time and later again one more row like that..
In this I have to add different data to the two columns of a row dynamically. For example for the first column I have to add 'MOVE' and second column 'LEFT' like this.
Please if any one have any idea how to do this please reply me.

You can create an appropriate data type (class) to hold the data.
Then you can bind the ListView to a collection (an ObservableColection<>
is a good coice here). Once you have that, you could use the DisplayMemberBinding
property of GridViewColumn to have the columns display the desired data from
your data type, for example
<GridViewColumn Header="Type" Width="50" DisplayMemberBinding="{Binding Path=Type}" />
<GridViewColumn Header="Description" Width="130" DisplayMemberBinding="{Binding Path=Description}" />
When you dynamically add or remove objects from the collection, rows will be added
or removed from the ListView.
Lots of info and examples here: Data Binding[^]
