It seems that when I refreshed my project from SVN, it did not save the debug settings. It reset my debug switches, which I was not expecting.

Thanks to you and Mark....I'm back in debug state!!!

Permanent until a user or an application deletes something.

There are two types of isolated storage - "Application" and "Site". Both are scoped by the user..since the files are stored under the user's AppData on Windows. These are permanent and not cleared even when you clear the browser's cache or restarting the system.

Now...bring me that horizon. And really bad eggs...Drink up me hearties, YO HO!

Getting an Item Template to raise selected event properly

Michael Eber19-Jan-10 6:04

Michael Eber

19-Jan-10 6:04

Here is my setup:

I have a ListBox which contains an ItemTemplate.
The ItemTemplate incorporates a checkbox with name/checked state bound to the ItemSource object.

issue: when the checkbox is checked (or unchecked) the selected event is not picked up. Basically you have to click the checkbox text on the far right to actually select it.

This can be a rather delecate issue as a user may think they are setting values for the item they checked but actually changing values for a previously selected item.

Is there something in the xaml I can set or do I handle the checked event and set that object to selected item?

If I'm reading correctly - the checkbox button
is eating the mouse click events (like buttons do)
so the listbox selection doesn't change, correct?

If so, I would try adding Checked/Unchecked event
handlers to the CheckBox. In the handlers, the sender
parameter will be the CheckBox. The CheckBox's DataContext
should be a reference to the selected item in the ListBox's
ItemsSource. Set the listBox's SelectedItem property to
the CheckBox's DataContext value.

(Note I didn't test this Smile | :)

)

private void CheckBox_Checked(object sender, RoutedEventArgs e)
{
    myListBox.SelectedItem = (sender as CheckBox).DataContext;
}

private void CheckBox_Unchecked(object sender, RoutedEventArgs e)
{
    myListBox.SelectedItem = (sender as CheckBox).DataContext;
}

Mark,

Yup, you understood correctly, the checkbox is gobbling up the event and the listbox does not select the item. I pretty much thought I'd have to do what you suggested, setting listbox.SelectedItem to the corresponding checkbox.

Thanks Mark,

Michael

Transparency in WPF

Hi,

I have created a 3D object in WPF using c#. I would like to make them transparent. I tried reducing the alpha value in color palette. Also, I tried to use Opacity property of Brush(Eg: brush.Opacity = 0.25;). Both of them doesn't seem to work. Could some one give some suggestions. Thanks in advance!!!

Well the alpha should take care of this for you. You can look at my article on XAML Series 2. It should some alpha blending. Mostly depends on what is being over laid over what. The example is a silverlight applet that uses what I call a sparkel filter, the filter uses different alpha values to create a star burst pattern in a matrix to give the desired effect.

If you want the whole window to be transparent you need to set the aplha values all the way down the widget hierarchy.

Hi,

I am making a mini paint like application using WPF.. Does anyone know how to go about implementing a Pencil tool in WPF (C# preferred.)

thanks in advance.

You'd want to draw to a Canvas. A pencil tool would probably best be implemented as a Path. Handle click events and mouse move events to do the drawing.

If the XML isn't well formed, this would be thrown. Are you sure that it is well formed?

Well, I just followed the step on WPF Data Binding Tutorial. There's a xml file that I should make, I just only changes the location of images (add image on image_form). May be I should compare which one of code xml that was true. I'll check it now, can you teach me more.. Sniff | :^)

In my xaml page I would like to display an image from my C# project's resources folder depending on the value of binded data. To explain it better, I want to display one of three images (information.png, warning.png, or error.png) depending on what type of data it is. Is there a way to make such a conditional statement strictly in XAML markup language? Thanks.
