Just remove

	<Setter Property="HorizontalAlignment"   Value="Center" /><br />
<br />
	<Setter Property="VerticalAlignment"     Value="Center" />

from your style and things should be fine.

*Edit*
You would also need to remove the hardcoded width
<Setter Property="Width" Value="30" />
from your first style.

Really weird.

I have used the following code (I even changed the text but then I had to increase the heights of the stackpanel to 160 each).

Image.ImageSource to string ?

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);

        //////////////////////////////////////////////
        //convert System.Drawing.Image to WPF image
        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,

                <Trigger Property="IsMouseOver" Value="True">

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>

Dimming the indicator of a custom progressbar

31-Mar-10 18:36

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

Checking if User-Control DLL is being used by EXE

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;
}

If it is VS 2008, make sure you have SP1 installed. Try reinstalling the SL toolkit.
