That is the event you need to handle.

Yes, I understand.

Do you understand what I mean ?

The below code assumes that my TabControl is named tcDemo.

You can also use the e.AddedItems property to get a list of selected items.

The way I'm doing it, is more direct.

Private Sub tcDemo_SelectionChanged(ByVal sender As Object, _
ByVal e As System.Windows.Controls.SelectionChangedEventArgs) Handles tcDemo.SelectionChanged

Dim objTabItem As TabItem = CType(Me.tcDemo.SelectedItem, TabItem)

End Sub

Thanks anyway.
I'm working C# and I couldn't understand your VB code well.
But I used this code and my problem solved.

void TabControl_SelectionChanged(object sender, 
             SelectionChangedEventArgs e)
{
        MessageBox.Show(((TabControl)sender).SelectedIndex.ToString());
}

Good. Looks like you on your way.

Below is a great link to convert between VB.NET and C# and C# to VB.NET. It's free and works great.

How to create simple editable document under WPF?

MikeKus25-Sep-08 9:40

Hi!
I'm trying to create a small program that allows to create,edit and print several slides. Idea is similar to PowerPoint, although much much simpler (only editable RichText and Images from files placed on the slide)

How can I do this? (FlowDocument won't work because fixed coords are necessary for all the elements)

I can think of using Canvas layout, dynamically destroying old controls(Saving the edited text and links to images to some internal structure) and creating-placing new EditText and Image controls each time user clicks Next or Previous slide buttons(filling them with data from saved internal data).

But how do I allow zooming of this canvas with controls so that if user zooms in, scroll bars appear, text and image controls enlarge correctly like in any Office App.
Will I be able then to print this canvas with all the controls on it?

Is there a better way to do this?

Thanks!

Have you tried the RTF control? There is a great example in the SDK examples.

Anyone working with CAL - Commanding Issue

Jammer25-Sep-08 9:01

Hi All,

I'm currently implementing some commands on Views / Controllers in a WPF app but I'm seeing something I didn't expect with the DelegateCommand. My Can<insert command name> only gets called once during the initial 'setup' of the view. So for instance the app gets loaded, all the Can whatever commands get called and setup various things, but when a command is raised and the state of the return values from these CanExecute switch the UI doesn't respond ... I expected them to operate more like 'normal' WPF command bindings.

Anyone have any ideas?

You can't. Silverlight has been designed to be cross platform, and DirectX is platform specific.

If I understand you correctly, you have 3 "windows" in your application, 1 of which is a container. The container should then open 1 of the other windows in the stackpanel. If this is the case, the best way to do this is to make the other 2 windows UserControls instead. These can then be hosted in your stackpanel, 1 with its Visibilty set to Visible and 1 set to Collapsed - this means you'll only see 1 item in the stackpanel at a time. Then, use a trigger to change the Visibility of the items based on the menu click.

Progress indication while uploading/downloading sample

Hi,
During uploading Progress indication is while reading the file ( with STreamWithProgress )
not while writing into the file. So the progress bar shows uploading is finished. But the file is still getting created. Please anybody help me understand this.

thanks
Rajani

Uploading to what? You need to provide far more information before we can help. Is this a WPF issue?

Sorry for not providing enough info.
I have WCF web service to upload files. Windows application calls upload file method on the web service. I have used the sample given in the below link
http://www.codeproject.com/KB/WCF/WCF_FileTransfer_Progress.aspx

I have seen that while reading the file the progress events are sent .
Hence after progress bar value reaches max, writing to the output file starts. Please clarify.

Thanks
Rajani

Don't you think you should ask this question on that article? I don't have time to download the sample, and debug it to find out what's going wrong with the progress bar - but I would say that the progress bar is probably tied to the upload operation rather than to the upload and write operation.

Does WPF create own images real time ?

Hi.
Does WPF create own images real time ?

Thanks in advance

I'm sorry Mohammad, but I'm not sure what you are trying to get at here. Could you rephrase your question a bit and I'll do my best to answer? What type of image are you talking about - a gif, or a XAML vector image? What do you mean by real time? Do you mean at runtime?

Yes, at run time.
