I neglected to remove the width property from the border style.

Hi,
I have the below XAML code :
<Window x:Class="WpfApplication1.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
DataContext="{Binding RelativeSource={RelativeSource Self}}"
WindowStartupLocation="CenterScreen"
Title="Window1" Height="300" Width="300">
<Grid>
<Image x:Name="TestImage" Source="{Binding Path=ImageSource}" />
</Grid>
</Window>
Now, I'm gonna set the `TestImage` with the below method :
Image Base64StringToImage(string base64ImageString)
{
try
{
byte[] b;
b = Convert.FromBase64String(base64ImageString);
MemoryStream ms = new System.IO.MemoryStream(b);
System.Drawing.Image img = System.Drawing.Image.FromStream(ms);
System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(img);
IntPtr hBitmap = bmp.GetHbitmap();
System.Windows.Media.ImageSource imageSource = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(hBitmap, IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
Image wpfImage = new Image();
wpfImage.Source = imageSource;
wpfImage.Width = wpfImage.Height = 16;
return wpfImage;
}
catch
{
Image img1 = new Image();
img1.Source = new BitmapImage(new Uri(@"/passwordManager;component/images/TreeView/empty-bookmark.png", UriKind.Relative));
img1.Width = img1.Height = 16;
return img1;
}
}
I've used the following code, but it doesn't work :
public string ImageSource { get; set; }
ImageSource = Base64StringToImage("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").Source.ToString();
Actually , I have a problem with converting ImageSource to string !
Would you please guide me, how I can do it ?
Thanks.

Hi
I want to set the backgound of the DataGridRow based on the item which is displayed by that row. I use the DataGrid to diplay the people in the phone book. I want to set the background of the row based on the country in which that person lives. Does anyone knows how can I do that? Any advice will be appreciated.
Thanks in advance,
Uros

You could change the background color using a trigger as shown here.

I found this post too and some others. But i can´t find a solution for my problem. I found an example which is almost i want.
The border in this solution is very "light" but i need a solid border. I tried alot but i didn´t hit the correct switches.
So can someone point me to the right way?
<Style x:Key="RedGlowItemContainer" TargetType="{x:Type ListViewItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListViewItem}">
<Border Background="Black" CornerRadius="4" BorderThickness="1" x:Name="IconBorder" Margin="1,1,1,1" >
<ContentPresenter />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="true">
<Setter TargetName="IconBorder" Property="BitmapEffect">
<Setter.Value>
<OuterGlowBitmapEffect GlowColor="White" GlowSize="5"/>
</Setter.Value>
</Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

Check the documentation for the different properties of a Border control. Change the colour, increase the thickness etc.
It's time for a new signature.

Use stype for Hyperlink:
<Style TargetType="{x:Type Hyperlink}">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Foreground" Value="DarkSlateBlue" />
</Trigger>
</Style.Triggers>
<Setter Property="Foreground" Value="SteelBlue" />
<Setter Property="TextBlock.TextDecorations" Value="{x:Null}" />
</Style>
------------------------------
<TextBlock><Hyperlink NavigateUri="http://msdn.microsoft.com/library">Navigate to MSDN</Hyperlink></TextBlock>

Hi Hema,
You can easily remove the underline from the hyperlink just set the property TextDecorations = "None" of hyperlink. And to change the color of hyperlink dynamically you can set the color in setter. I have used same in grid and working fine.
Hope the above will help you.
<Style x:Key="DataGridHyperlinkStyle" TargetType="{x:Type Hyperlink}">
<Style.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type WpfToolkit:DataGridRow}}, Path=IsSelected}" Value="true">
<Setter Property="Foreground" Value="White"/>
</DataTrigger>
</Style.Triggers>
</Style>

Hi there,
I am new to WPF, I have just learned how to customize the progressbar by using a control template. I made it so that the indicator part of the progressbar has a gradient effect.
Now i actually want it to fade in as the value increase, I know that I can make use of the triggers on the value of the progress bar and set the opacity of the indicator, but i am not sure how that can be done.
Also, I would like to have a box following the top of the indicator to indicate the value of the progessbar, my approach is to create another column from the grid, place a textbox inside, and then again using trigger change the coordinates of the box. But i am not sure how i can convert the value of the progressbar to the coordinates of the textbox.
here is what i have so far

I've created a user-control for WPF using C#. Control has a warning MessageBox, which I want to appear only if it is being used by some EXE, but it should not appear while developing. So basically, it should appear the way it appears for unregistered controls. Currently it is appearing in both development/runtime. How can I do that?

I use the following simple test:
_designMode = DesignerProperties.GetIsInDesignMode(new Button())
|| Application.Current == null
|| Application.Current.GetType() == typeof(Application);
if (!_designMode)
{
var designMode = DesignerProperties.IsInDesignModeProperty;
_designMode = (bool)DependencyPropertyDescriptor.FromProperty(designMode, typeof(FrameworkElement)).Metadata.DefaultValue;
}

Hi,
After installing Silverlight Tools I have Silverlight Application template is missing. The only templates are present Silverlight Class Library, Silverlight Navigation Application and Silverlight Unit Test Application. I already tried to uninstal and reinstall without any success, template still missing. Any idea how to fix it without rebuilding my PC?

Which version of Visual Studio are you using?
If it is VS 2008, make sure you have SP1 installed. Try reinstalling the SL toolkit.

It's VS 2008 with SP1 installed, and I already tried twice to reinstall
|

Open the visual studio command prompt and run this - devenv /ResetSettings.

Hi,
Apologies this is a general question, and I am looking for a ball-park answer.
I have a little experience in MATLAB, a little experience in C, good experience in SQL, and no experience with C#, .xaml, or WPF.
I have a project at work to develop an application in C# WPF that will need to examine and modify values in a SQL database. A fair part of this project involves me learning the necessary skills.
So 2 questions:
1) How long would you expect me to need to spend to get my skills up to scratch?
2) What resources would you recommend are best? In your experience is there significant benefit to attending a course on these subjects to speed learning up?
So far I have read (and done examples from) a C# .NET in 24 hours book, and feel like I have only a basic understanding.
Cheers
Tim
