That's right. Just remember that it's an application resource, so you don't have to wrap it in a container Resources section such as a Window.Resources.

Yes, but I'm not setting the style in the Application XAML, I just want to point it to my resource dictionary (Styles.XAML) :

<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Styles.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>

I think you misunderstand me. Because you have created this in a ResourceDictionary, you don't need the Window.Resources part - that's what I mean by application resources. The way you are merging your resource dictionary in is spot on.

Hi Copec,

"Being new to programming I'm here to ask experienced programmers what is good and what isn't."

I think you'll find a lot of great WPF tutorials and articles here on CodeProject in the writings of Sasha Barber, Marc Clifton (the man on XAML), Josh Smith, Pete O'Hanlon, and others : please look them up.

While I am experienced as a programmer in C# and WinForms, I am very new to WPF : so I can only tell you what I have heard from someone who is very "deep" into WPF, and what I am finding valuable to me as I am plunging in to learning it myself. So you are warned Smile | :)

A very talented WPF programmer I recently met who has published a well-received article here on WPF on CodeProject recently recommended Adam Nathan's book :

Windows Presentation Foundation Unleashed (Sams, 2007)

to me, and I am finding it very valuable. Nathan is a senior software developer at MS, and his co-author was a lead developer on 3d for WPF (is Nathan still at MS ? Don't know : his blog is just a bunch of ads for his books).

I am also reading Matthew McDonald's book on WPF :

Pro WPF in C-Sharp 2008 - Windows Presentation Foundation with .NET 3.5, Second Edition; Matthew MacDonald (Apress, 2008)

I have a very high opinion of every book of McDonald's I've read : I think his book :

Pro .NET 2.0 Windows Forms and Custom Controls in C# (APress 2008) on WinForms and UserControls is superb.

In terms of C# itself, independent of WinForms and WPF, I personally think Jessie Liberty's books for O'Reilly are the best including :

Programming C# 3.0 (O'Reilly 2008)
Visual C# 2005: A Developer's Notebook (O'Reilly 2005)

... edit ... and, I forgot to say Andrew Troelsen's latest :

Pro C# 2008 and the .NET 3.5 Platform, Fourth Edition

Is the best I know of for "language theory."

Good luck, Bill

Adjusting WPF Layout Controls

Hi All,

In a WPF UI Application, I have 4 controls and 3 radio buttons( say write, read and load). I have aligned them Properly too.

4 controls are : 1. Tabcontrol with listview in it 2. Stackpanel with checkboxes 3. Stackpanel(orientation - Horizantal) with textbox and browse button 4. A stackpanel with Textblock and Listview.

My question is, for Load RadioButton, I should have all the 4 controls stacked vertically. (this is no issue, its done.. )

for Write button, the controls 2 and 3 should be invisible and the control 1 and 4 should fill tht area.

ctrl ht
1 150
2 100
3 30
4 200

When i press write, the ctrl 2 n 3 shuld become invisible and the ctrl 1 height should be (150 + 75) and ctrl 4 should be (200 + 55).. which makes ctrl1 lower limit should move down to 75 pixels and ctrl 4 upper limit should be 55 pixels above..

please help me in doing this.. I am using XAML and C# for this WPF app

thanks Ramm

If you want to change the heights, you probably need to do that manually. I would imagine if you had the pairs of controls inside a single control of the combined height, and had the control you don't hide set to fill the available area, then the other control would limit it, or not, depending on if it is collapsed or not. But as you want to hide a control that is 100 high and replace it with 75 pixels of space, you'll need to do something more direct and manual.

Silverlight design

29-Jul-09 21:37

Ok, I appreciate the strong data orientated design of Silverlight (WPF) and the power of Binding etc, but after all it is UI technology...

The omission of even basic UI support really baffles me, simple things like:
- looping over controls, did they assume my data object is going to represent all the attributes of my presentation layer? (Try setting custom values for the GroupName of radio buttons after using Binding to generate them)
- the TreeView's SelectedItem attribute gives you the data object bound to the Tree Node that is selected, how do I get (or set) the selected Node? And I need to get the parent Node of the selected Node?

Did Microsoft assume that we wouldn't need to do these things, or didn't they have enough time to include them (were they more intent on selling than building?) I understand Silverlight is a compact framework and that they had to omit certain things, but to omit basic UI functionality from a UI framework???

It's still present - you use the VisualTreeHelper class to iterate over the controls.

That's not the case - you need to learn the new way of doing things that is behind Silverlight and WPF. You can't really use the same techniques you used in WinForms/ASP.NET; it's a totally different way of working. Once you get your head round it, it makes a lot of sense - and is actually very, very powerful.

Sure, but why need another class to iterate over a collection (surely there is a collection that holds the controls)? Now I need to get the .Count and then for over it, like languages from the olden days... Why can't I LINQ to get controls etc...

Pete O'Hanlon wrote:

The fact of the matter is that the functional requirements are the same, but the technical ability to fulfill the requirements has been stripped and now needs lots of work arounds and looping...

Pete O'Hanlon wrote:

I agree, if you do things the way that they work, if you need something slightly different, you have no power at all and need to loop and hack...

I don't mean to be negative, but I am very disappointed...

Primarily because there are actually two trees (well, in WPF there are), the logical and the visual tree. Which one would you like to loop over?

WPF FlipBook Orientation Issue

I would say that you should probably read about MVVM and how we can write tests from ViewModel? Writing in code-behind is not so common in WPF/Silverlight. UI and logic seperation is important.

I have downloaded the WPF FlipBook control from: http://blogs.msdn.com/mitsu/archive/2007/04/18/wpf-book-control.aspx

I modified it's XAML to make it a Landscape Book. But my problem is: When I want to goto the next page the transition happens from right to left. I want it to happen from any corner of the bottom. I didn't find anyway to make the transition happen from bottom to top only.

Can anyone please help me regarding the same?

By default the Book Binding is at the left side. How can I change it to top?

The answer has to be, by reading the XAML, understanding it, and modifying it.

Plotting a Silverlight chart/graph by getting data from SQL database

Re: Plotting a Silverlight chart/graph by getting data from SQL database

29-Jul-09 18:06

Hi all.

I want to create a Silverlight graph that plots data by getting them from a database when the user enters them from the UI. I hope to use LinQ to SQL to do this. I am also using Visual Studio 2008 .NET 3.5, SQL Server 2008.

Can anyone help me? Feel free to ask me for any additional info that might be of help.

I'm sorry, but you're unlikely to find anybody willing to write the amount of code for you that you seem to be requesting. You have all the right ideas, but it seems that you lack the SL capability/inclination here - if that's the case, start off with a smaller application and get your head round that at first.

Ouch. Right, let's start by working out what you do know - out of the list you provided, what are you comfortable with? For instance, are you thoroughly versed in LINQ?

Another big ouch, I'm versed in neither. I'm only slightly comfortable in C# and that's it. I've done a few tutorials on creating simple charts and a simple Silverlight application that gets data from WCF using LinQ to SQL.

So, you've got the basics there. If you are using the Silverlight Toolkit charts, this page has some useful samples to demonstrate how to populate the charts[^].
