Thanks Richard, but not quite what I am looking for.
The control I am currently working on originated as a derived class of System.Windows.Controls.Panel. I got this to a point where I was happy with measure and arrange overrides of child objects. I wanted this container/panel to have a visual style to be applied to it, as well as the option to create alternate control templates. I changed the derived class from System.Windows.Controls.Panel to System.Windows.Controls.Control . At this point I lost the rendering of my control.
I am looking for some information on how to get the rendering of this object back, also how to set a control template for it.
Do I need to override any rendering code when working with a base class of System.Windows.Controls.Control?
I have tried to use a control template in the way I would have used it for a control derived off another base class eg.
SearchTextBox : TextBox
DefaultStyleKeyProperty.OverrideMetadata(typeof(SearchTextBox), new FrameworkPropertyMetadata(typeof(SearchTextBox)));
CustomControl : Control
DefaultStyleKeyProperty.OverrideMetadata(typeof(CustomControl), new FrameworkPropertyMetadata(typeof(CustomControl)));
When I try to view this template in Blend I get the following error.
Unable to cast object of type 'Microsoft.Expression.DesignSurface.ArtboardBorder' to type 'ParentOfCustomControl'
(The custom control has a fixed Parent type which is derived from System.Windows.Controls.Grid)

Sorry Mikey, but you have me there. I only posted the link to you because it was something I had previously used and thought it fitted what you were looking for. As for Blend, it's not a product I have had experience of.

Hi.
I have the following code in a WPF Application :
<br />
<br />
<Window x:Class="WpfApplication1.Window1"<br />
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"<br />
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"<br />
Title="Window1" Height="300" Width="300"><br />
<Grid><br />
<ListView Name="listView1" Margin="11.5,7,10.5,19.5"><br />
<ListView.View><br />
<GridView ><br />
<GridViewColumn Header="1"/><br />
<GridViewColumn Header="2"/><br />
</GridView><br />
</ListView.View><br />
<br />
</ListView><br />
</Grid><br />
</Window><br />
<br />
But in designer i see the listview empty and i dont see the 2 columns. I only see them on runtime.

I copied your code as it is in to a new WPF Project and I had no problems at all i.e. the columns were visible in designer.
I use VS2008(SP1).

Ok.
It seems that an update to sp1 was required.
Thanks.

Hi,
I'm using a Grid with a TextBlock as a Y Axis Label so I need to rotate the text 90 (or 270) degrees, problem is that when you use a RotateTransform or PlaneProjection RotationZ="90" the text rotates but does not go beyond what the width of the label is so you get a chopped off piece of text running vertically, but only as high as the TextBlock is wide, am I doing something wrong?
Here's the XAML (using projection):
<Grid x:Name="LayoutRoot">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="23"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBlock Text="Test Vertical text" Grid.Column="0" HorizontalAlignment="Center" VerticalAlignment="Center" RenderTransformOrigin="0.5,0.5">
<TextBlock.Projection>
<PlaneProjection RotationZ="90"/>
</TextBlock.Projection>
</TextBlock>
</Grid>

Yep, tried it, as soon as you limit the width of the textbox the text gets truncated to that...

A RotateTransform doesn't change the dimensions of your textbox.
Text truncation is a separate issue.

Not sure what you mean, could you maybe send me a snippet for this with a TextBlock of 90 Height and 23 Width (for example) with Vertical Text?
If tried using the RotateTransform and it still gives me the truncation, maybe I'm doing something else wrong...

If that's the dimensions you're using then I can see why text gets clipped.
A RotateTransform applied to a textblock will rotate the textblock, not just the text.
So you don't want to swap the width and height values.
You'll also need to be mindful of the element the textblock is contained in,
which depending on its type, could cause additional layout on the textblock.
Here's an example:
<Border BorderBrush="SteelBlue" BorderThickness="2" Width="300" Height="200" >
<Grid Background="LightSteelBlue" >
<TextBlock Text="Rotated Text" FontSize="12" FontWeight="Bold" Width="90" Height="23" HorizontalAlignment="Center" VerticalAlignment="Center" >
<TextBlock.RenderTransform>
<RotateTransform Angle="270" CenterX="45" CenterY="11" />
</TextBlock.RenderTransform>
</TextBlock>
</Grid>
</Border>

Hi Mark,
Thanks for the Snippet, if I use this the text displays vertically but I have whitespace on either sides of the text to the full width of the text, which means my entire Grid Column need to be the width of the text even though there is only a little bit of text in the middle of it, is there a way to avoid the white space? (Other than calculating negative borders...)

Maybe try the LayoutTransformer in the Silverlight Toolkit[^]
...
xmlns:layout="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Layout.Toolkit"
...
<Border BorderBrush="SteelBlue" BorderThickness="2" Width="300" Height="200" >
<Grid Background="LightSteelBlue" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Border Grid.Column="0" BorderBrush="SteelBlue" BorderThickness="2" Background="AntiqueWhite" Margin="4" >
<layout:LayoutTransformer>
<layout:LayoutTransformer.LayoutTransform>
<RotateTransform Angle="270" />
</layout:LayoutTransformer.LayoutTransform>
<TextBlock Text="Rotated Text" FontSize="12" FontWeight="Bold" HorizontalAlignment="Center" />
</layout:LayoutTransformer>
</Border>
<Border Grid.Column="1" BorderBrush="SteelBlue" BorderThickness="2" Background="AntiqueWhite" Margin="4" >
</Border>
</Grid>
</Border>
Easier than trying to manually adjust margins/offsets.

I used the WPF ellipse in my program.
When I clicked on the ellipse, there will be blue dots appearing around it.
Why? How can I get rid of them?
|

The dot's are called a focus rectangle. To get rid of them you need to set the FocusVisualStyle to null for the particular button. You can do this like this:
<Button Content="..." FocusVisualStyle="{x:Null}" />If you don't want the focus rectangle on any button, you'd define a global style for all buttons and set it there.

Hi Everyone,
I am developing a web site that will be commercial but i want a really nice look and feel it. What will be the best to use? Is WPF a good approach? If so where may I find good look and feel of existing web sites to show to my customer? How easy is it to maintain?
I also heard that search engines are capable of getting all keywords if you use Silverlight/WPF. How true is that and would you recommend WPF?
Thanks
Chris

WPF is primarily a desktop application framework. Yes, you can deploy BAML application, but they only run on Windows. The web development area that uses XAML (the markup behind WPF) is Silverlight. Yes, Silverlight is SEO "friendly", so that's probably what you are looking for.

WPF mostly used to develop the desktop application.
i think you shoud use the ASP.NET+SQLServer+Ajax,if you want it to be more attractive,using the Silverlight~~
