I have a problem about displaying Image on Screen.
I created new WPF project in VS2010 and added the following code in MainWindow.xaml.
<Window
...>
<Grid>
<Grid.Background>
<ImageBrush ImageSource="image.jpg">
</Grid.Background>
</Grid>
</Window>
But displaying image.jpg is not that fast as I expected, and It doesn't show image.jpg immediately.
First it shows Empty Screen for a while(during rendering time, I think) and after that shows image.jpg.
How can I avoid the Empty Screen.
Please help me.
Thank you.
I think ImageSource.DownloadCompleted event, PriorityBinding and Binding.IsAsync will help you here...

I know that there are a lot of questions about this subject but it seems that no one tells why this is happening:
Maximized window:
unmaxmimized window:
This only seems happen when I have the medium or the larger setting, with the smaller the text is always sharp:
this is happening for all the text in the application, I already checked that the clear type is enabled and I read something about the allow transparency property I tried with both true and false but nothing changes.
How can I fix this?
Have you tried changing the text options?
TextOptions.TextFormattingMode="Display"
Try to modify the XAML:
<Setter Property="TextOptions.TextFormattingMode" Value="Display"/>
Also, not set the value to "Ideal" which is there by default.
<Viewbox Height="100" Stretch="Uniform" TextOptions.TextFormattingMode="Display">
<TextBlock FontFamily="Georgia">My Cool Text</TextBlock>
</Viewbox>
Could be a bug in WPF but this workaround is in place for many users!
I am developing an application in WPF using MahApps.Metro 0.12.1. In this application I don't show the titlebar, staying visible minimize, maximize and close commands. Below I show the code:
<controls:MetroWindow xmlns:views="clr-namespace:View.Views"
xmlns:titleBar="clr-namespace:View.Views.TitleBar"
x:Class="View.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
GlowBrush="{DynamicResource AccentColorBrush}"
ShowWindowCommandsOnTop="False"
ShowTitleBar="False"
Title="MainWindow" Height="400" Width="600"
AllowsTransparency="False">
<Grid>
...
</Grid>
The problem arises when I upgrade to the version 0.13.1 of MathApps.Metro, where these commands are not displayed, forcing me to re-establish the titlebar to display the commands again ShowTitleBar="True" and this is what I do not want: display the titlebar.
I was looking at the release notes of MathApps.Metro 0.13.1 and reports that changes were made to the section of the titlebar​​, but no further details are given.
My questions are: Is there a simple way to display the minimize, maximize and close commands without showing the title bar? What is the best way to do this?
thanks
you can put the window buttons directly in your main window like this
<Grid>
<!-- the window button commands -->
<Controls:WindowButtonCommands Panel.ZIndex="1"
HorizontalAlignment="Right"
VerticalAlignment="Top"
Height="{Binding TitlebarHeight, Mode=OneWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Controls:MetroWindow}}}" />
...
</Grid>
hope that helps

Actually not very simple, but possible. Basically you need to create your own Style template and override the ContentPresenter for your window to do so.
You may take a look at this question.
Besides that, this post will guide you through the process of designing your own titlebar.
I am trying to load a UserControl in the Window by using content control's content property in code behind. Every thing is fine, but my friends were not able to see all the control on the page due to resolution problem. How can I fix this to have scroll bar. I have tried putting ScrollViewer also, but it's not working. So, my solution works on the bigger Window which developed, but its not working on the Smaller resolution windows.
Sample code structure of loading the UserControl:
Window.Xaml
<ScrollViewer>
<ContentControl Name="ContentX" Margin="15,10,15,0" HorizontalAlignment="Center" VerticalAlignment="Center">
<Label FontWeight="Black" FontSize="18" FontFamily="Calibri">Some Content</Label>
</ContentControl>
</ScrollViewer>
Window.Xaml.cs
ContentX.Content = new UserControl();
UserControl.Xaml
//Contains the Code for User Control
I got it solved my Content Control is in another Grid Column where i fixed the width and height to be *, now i removed it it's working fine when i place it inside a Scroll Viewer
I've followed some examples trying to layer a rectangle over the WebBrowser object:
Here is the MSDN example link. (I got it to work)
Layers issue using Z-Index
Here is the code I'm trying to get to work:
<Grid>
<Canvas Margin="2,4,0,-450" >
<Rectangle Height="452" Canvas.ZIndex="1000" Name="rectangle1" Stroke="Black" Width="524" Opacity=".5" Fill="#8CBABABA" Canvas.Top="-7" Canvas.Left="-3" />
<WebBrowser Name="mapBrowser" Canvas.ZIndex="999" Margin="5,5,5,5" Height="452" Width="516" Canvas.Top="-11" />
</Canvas>
</Grid>
I'm trying to make the WebBrowser appear grayed out by making the rectangle appear over top of it. I'll also disable it.
Can anybody point to what I'm doing wrong?
I solved this issue by creating a .png image which I placed in the same space as the webbrowser. It looks like a grayed-out version of what first appears in the webbrowser. Then I conditionally hid the webbrowser which makes the image visible. This is the only way I've found to make it work using .Net 4.0.
I have a blank window and i want a image in the center.I first tried dragging and dropping in the designer.Doesn't work.Then i tried an assortment of other examples on the internet.Couldn't get it to work either.one kinda worked but it wouldn't let me change the image's position.
Put an Image control in a Grid:
<Grid>
<Image Source=... Stretch="None" />
</Grid>
