Default Focus Behavior

brandontruong — Sun, 30 Aug 2009 11:27:35 +0000

I would love to share with you guys about Default Focus Behavior which I just created an hour ago because I thought this behavior would be very handy.

With this behavior, we would be able to set focus to any controls when we trigger any control events.

For example, whenever we click the button, we want to textbox got focused, or when we select the Option 1 for the very first time, the textbox will get focused as below image.

To set the focus for a control only once, all we have to do is set

IsOnceOff = “True”

Click the icon below for the source code, so you can have a play with it

Hopes this helpful

TextWraping in Silverlight

brandontruong — Sat, 29 Aug 2009 00:00:41 +0000

Just a little thing I came across when I am trying to set TextWraping property for a TextBox, but the text doesn’t seem to be wrapped. Then I realized if the TextBox is setting with TextWraping greater than 1, the text won’t be wrapped. Just a little thing to keep in mind

Datagrid Missing Binding Error

brandontruong — Thu, 20 Aug 2009 12:54:12 +0000

I have run into this silly mistake, and it took me 2 hours to figure it out

I am writing it down here for my own reference, and if you ever ran into this problem, hope that this can help you fix your problem quickly.

The problem is I had a datagrid column with the Header but not the Binding, for example

This will cause the below error at runtime

To fix it, all I had to do is to put the Binding in it

Hope this helps

UpperCase Behavior

brandontruong — Mon, 17 Aug 2009 11:13:54 +0000

I was asked to create a TextBox input which has only UpperCase letters. After a bit of research, I have found this article which has inspired me to come up with this solution. As we all know that Behavior is a cool stuff in Silverlight 3, so I decided to use the concept from that article and create a Behavior which detects all the key and uppercase it. Feel free to download the source code and have a play with it.

FocusManager

brandontruong — Wed, 17 Jun 2009 02:11:25 +0000

I’ve read this article about FocusManager. I think it could come handy sometimes when you want to know what element has focus. FocusManager class which can be found in the System.Windows.Input namespace. Below is the sample of how to use itThe FocusManager class has only one static method:

public static Object GetFocusedElement();

Using the FocusManager is easy. Here’s a small example of a possible usage:

var focusedElement = FocusManager.GetFocusedElement() as Control;
if (focusedElement != null)
    Output.Text = focusedElement.Name;

One last note: The FocusManager class is also available in the “normal” .NET Framework 3.0 or later.

Binding for Converter Parameter

brandontruong — Tue, 09 Jun 2009 05:01:52 +0000

I have come across the situation where I need to do some Binding for ConverterParameter. Something like

I have done lots of research, and I found out that its impossible to do binding for ConverterParameter.
So I came up with the Solution. I created the Converter but inherited from FrameworkElement

public class ShowDeleteServiceConverter : FrameworkElement, IValueConverter

In the converter class, I created a dependency property

Now, I can do the Binding as usual

And

It might not be the best solution, but it works for me so far. If you have any idea, feel free to drop me comments.

Cheers,

How to Change the Startup Class

brandontruong — Mon, 26 Jan 2009 00:24:27 +0000

Another great tip from Mike Snow. Read the original article here

When a Silverlight application is launched the entry point is a class that inherits from System.Windows.Application. By default, when you create a new Silverlight application project, this would be your App class which gets defined in App.xaml.cs. You can, however, change which startup class you want to use. In fact, if you do not plan to use XAML at all you can reduce the size of your application by deleting the Page and App classes including the XAML and code behind files.

To accomplish this follow these steps:

Step 1. Create a new Silverlight application project adding a new ASP.net web project to host the Silverlight app.

Step 2. Delete App.xaml and Page.xaml (the CS files will be deleted also).

Step 3. Create a new class and call it StartupTest.cs

Step 4. Modify your new class to inherit from Application as seen here:

public class StartupTest : Application
{
    public StartupTest()
    {
    }
}

Step 5. Right click on your Silverlight application project in the Solution Explorer of VS. From the context menu choose Properties. This will bring up the Properties dialog. Click on the Silverlight tab at the top-left and change the Startup object to be your class as seen circled here:

Step 6. Go back to your StartupTest class. Add an event to monitor for when the application has started. You don’t want to do anything until after this event has started.

public class StartupTest : Application
{
    public StartupTest()
    {
        this.Startup += new StartupEventHandler(StartupTest_Startup);
    }
    void StartupTest_Startup(object sender, StartupEventArgs e)
    {
    }
}

Step 7. The Application.RootVisual is root pointer to the main application UI. You will need to create this object to point an object such as a Grid or Canvas control. Once created, you can add additional controls to the children as you see fit. In the example below, I have created a Canvas as the root and configured its background color to be black, its width to be 800 and height to be 600. Also, I have added a Textbox to the Canvas control.

void StartupTest_Startup(object sender, StartupEventArgs e)
{
    this.RootVisual = new Canvas();
    ((Canvas)this.RootVisual).Width = 800;
    ((Canvas)this.RootVisual).Height = 600;
    ((Canvas)this.RootVisual).Background = new SolidColorBrush(Colors.Black);
    TextBlock tb = new TextBlock();
    tb.Foreground = new SolidColorBrush(Colors.White);
    tb.FontSize = 20;
    tb.Text = "NO XAML NEEDED!!!";
    ((Canvas)this.RootVisual).Children.Add(tb);
}

Step 8. Run the application and you will see the following image rendered in your browser: Technorati Tags: Silverlight

Selecting a Block of text

brandontruong — Thu, 04 Dec 2008 00:40:53 +0000

If you are COPY & PASTE, the blog here is showing you a very cool trick to give you more power in term of COPY & PASTE

Below is a brief content from the original post.

By default normal text selection is line by line. For example it’s not possible to select just the items to the right of the equals sign.

However, Visual Studio does offer this ability using block selection. Block selection is sued to select text in a block as opposed to line by line. Essentially allowing you to select text regardless of what line you are on. For example, select the key while selecting text to do the following.

Block selection can be used with both the keyboard and mouse. When using the keyboard hold down the + and use the arrow keys to perform the block selection.
