How can one apply an application style to the Common Dialogs? I've got a dark style going on in my app and this file open dialog is so bright it is jarring. Any ideas?
<br />
Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();<br />
dlg.FileName = "Document";
dlg.DefaultExt = ".txt";
dlg.Filter = "Text documents (.txt)|*.txt";
<br />
Nullable<bool> result = dlg.ShowDialog();<br />
<br />
if (result == true)<br />
{<br />
string filename = dlg.FileName;<br />
}<br />
Sincerely,
-Ron

Ron,
Dialog boxes are generally styled according to the operating system, as opposed to the UI that opened them since the users desktop theme will be used to style the dialog box. Example, Windows XP and Vista File Open dialogs look and work slightly different and are styled according to the users desktop theme.
If you check out the WPF SDK, there is a Vista Bridge library that gets you going with using dialog boxes that are operating system specific. I have been hoping that Microsoft would bake operating system dialogs into .NET so that no matter which O/S was running the correct dialog for that O/S would display without a lot of extra work on the developers part.
You "could" always write your own... No fun working with the Win32 API if you don't really have to.
Sorry I could be of more help.

Ron,
Yes. Give this article a look: http://www.codeproject.com/KB/WPF/WPFTaskDialogVistaAndXP.aspx[^]
This is where you need to make a decision. You can have all custom dialogs or use the operating system ones.
For the message boxes, I wanted my XP users to have the rich features of the TaskDialog so I wrote the above library to provide that.
I also have similar boxes for my file dialogs.

Thanks for help

Don't know but Bea Costa has a great blogspot that shows how to hide/show the expander:

Perhaps there is a similar pattern for which you seek.

Can you be more specific. Not sure which product you are needing help on. What is the schedular? If that is a third party control, you would probably get much better help posting to the vendor, since we may not have that control.
Have a nice day,

You may want to consider using a Grid inside a ScrollViewer.
The Grid provides a very easy way to have two rows per hour like the picture and then you can add columns as required for each of the actual schedules.
The wrapping ScrollViewer allows you to contain the grid in a certain amount of space and then have the user scroll up and down.
Then add child border controls that span the required number of Grid.Rows. For example, if you have a 2 hour appointment then you would add that border control and have its RowSpan property set to 4. You can style the border control any way you want.
You can then add a TextBlock that displays the text of the appointment. If you have multi-line appoinments you can use some cool features of WPF inside your TextBlock to display formatted text.
Check this very simple example out:
<TextBlock>
<Run FontWeight="Bold">Mole</Run> loves the managed heap<LineBreak />
I hope this helps you get started!
</TextBlock>

Hi All,
Not been around here for a few weeks as I've just become a Dad!!
Anyway ... I'm just looking for a few pointers and wotnot on how best to approach this task. I'm currently starting work on my second WPF application for my employer and one thing I want to do is before moving either project forward any more is to standardise the look and feel between the two (and obviously any future applications). Also this means that other developers here can just plug in a set of standard styles and get to work on the logic rather than worrying about the look and feel (my job largely!).
The most obvious way would be to have a 'Styles' project in a separate Visual Source Safe project with a <controlname>.xaml file for each control (like combo.xaml, textbox.xaml etc) ... or just one large style.xaml containing all our style code (this could however become a very large single file!).
What I'm wondering is before I start on this as a project in its own right is there a better way than just having xaml files? Would it make sense to build a style.dll that could be plugged into any application that would only provide styles and control templates for consumption by other developers?
We are using the Infragistics controls here and they provide a similar approach whereby we could build theme.dll's for our users to then select a theme for their instance of our application. I think that from a consumption point of view that is a much neater solution.
Thanks in advance for any input.

First of all, congratulations. Boy or girl?
Secondly, we use a set of themes and load them in dynamically. The advantage of this is that we can change/upgrade applications merely by changing the themes. It's a convenient way to "freshen" up an application without having to manage lots of different codebases.

Hey Pete,
Its a lil girl! So cool ...
How do you store all the theme code though? Are you using DLLs that are distributed with your applications?
How do you manage that within a multi developer environment?

Yup.

By having a designer come up with the themes.

Ahh ok ... theme DLL's it is then. I thought that would be the best solution to this particular issue.
Thanks chap.

Thanks for this Pete, I've pretty much got a working style.dll done now. Lots of tweaking to do and wotnot but this is indeed a seriously neat solution.
Just a quick one, do you have any neat tricks that you found on your journey down this route?

Hi,
I am trying to add some images to a listbox as described in Josh Smith's excellent article <a href="http://www.codeproject.com/KB/WPF/CustomListBoxLayoutInWPF.aspx">here</a>.
The only twist is that I need to bind to a list of BitmapImages that are created using a MemoryStream.
The images are being read from a database and I don't want to have to save them locally before showing them in the listbox.
I am not getting any errors - there are just no images being displayed.
I have taken the XAML entirely as is from Josh's article (I did try changing the Image binding from UriSource to StreamSource but that didn't work).
I'm pretty new to WPF so I'm probably doing something something really stupid, can anyone suggest what it is?
<code>
public static List<BitmapImage> GetProductImages() {
List<BitmapImage> images = new List<BitmapImage>();
using (SqlConnection cn = new SqlConnection(cnString)) {
string sql = "SELECT Top 10 ProductImage From Products WHERE NOT (ProductImage IS NULL)";
SqlCommand cmd = new SqlCommand(sql);
cmd.Connection = cn;
cmd.Connection.Open();
SqlDataReader reader = cmd.ExecuteReader();
while (reader.Read()) {
byte[] productImage = null;
productImage = (byte[])reader["ProductImage"];
if (productImage != null) {
System.IO.MemoryStream ms = new System.IO.MemoryStream(productImage);
BitmapImage bm = new BitmapImage();
bm.BeginInit();
bm.StreamSource = ms;
bm.EndInit();
images.Add(bm);
}
}
cmd.Connection.Close();
}
return images;
}
</code>
Thanks very much,
dlarkin77
Edit: I don't know why that link doesn't appear as a clickable link or why the code isn't in a code block. Sorry about that!

Hi,
Thanks for that tip.
The memory stream does indeed contain data. For testing purposes I've used the stream to save the image data as a file locally and then used this file to create the BitmapImage and that works fine. Can you suggest anything else?
Thanks very much,

Did you check out the two posts? They contain sample code for getting this to work. I'm sure it's something very simple since you are 98% there.
I'll try and write a sample, ( Karl does VB.NET but will be simple to translate or read ) tonight and post it.
