I am making a template control so that I can have a button with an image that changes when you click it. I also am trying to get text on top of the button that can change at run time. I have the button images and everything working but I can't seem to get that label at runtime so I can change the text. Here is the code in the xaml. I am missing the code behind
<UserControl.Resources>
<ControlTemplate TargetType="{x:Type Button}" x:Key="ActionButton">
<Grid>
<Label Panel.ZIndex="2" HorizontalAlignment="Center" VerticalAlignment="Center" FontFamily="Arial" Name="lblText" Foreground="#5E4421" FontWeight="Bold" FontSize="14">Test</Label>
<Image Name="Normal" Source="/AssaultWare.Controls;component/Replayer/Images/button_off.png"/>
<Image Name="Pressed" Source="/AssaultWare.Controls;component/Replayer/Images/button_on.png"/>
<Image Name="Disabled" Source="/AssaultWare.Controls;component/Replayer/Images/button_off.png" Visibility="Hidden"/>
</Grid>
<ControlTemplate.Triggers>
...
</ControlTemplate.Triggers>
</ControlTemplate>
</UserControl.Resources>
<Button Canvas.Left="471" Canvas.Top="465" Template="{StaticResource ActionButton}" Name="btnRight"/>
Difficult to decipher your question, but I think you just need to change the Label to a ContentControl and bind its Content property to the Button's Content property:
<ContentControl Content="{TemplateBinding Content}" .../>

I have a 'feedback' button which has this strange border:
So I searched online for some solutions and modified the control template, and I got this:
Control Template code:
<Button.Template>
<ControlTemplate TargetType="Button">
<ContentPresenter Content="{TemplateBinding Content}" />
</ControlTemplate>
</Button.Template>
So even after modifying the control template - I am getting a strange brown border. Help would be appreciated regarding this.
Button code:
<Button Grid.Row="3"
Grid.Column="2"
Grid.RowSpan="2"
Style="{StaticResource IconStyleBase}"
Name="Feedback_Button">
<Button.Template>
<ControlTemplate TargetType="Button">
<ContentPresenter Content="{TemplateBinding Content}" />
</ControlTemplate>
</Button.Template>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="218*" />
<RowDefinition Height="68*" />
</Grid.RowDefinitions>
<!--Icon-->
<Button Background="#3767B0"
Style="{StaticResource IconStyleContent}">
<!--Content-->
<Button.ContentTemplate>
<DataTemplate>
<Viewbox>
<TextBlock Padding="55"></TextBlock>
</Viewbox>
</DataTemplate>
</Button.ContentTemplate>
</Button>
<!--Icon Text-->
<Button Background="#FF2D5BA0"
Style="{StaticResource IconStyleSubBase}">
<!--Content-->
<Button.ContentTemplate>
<DataTemplate>
<Viewbox>
<TextBlock Padding="15">Feedback</TextBlock>
</Viewbox>
</DataTemplate>
</Button.ContentTemplate>
</Button>
</Grid>
</Button>
A DataTemplate defines the appearance of the the items that you set as Content of a button, but the button itself as a container has a default style and control template that defines how it looks like, along with its different states like mouse-over or pressed. That is where the border comes from.
You can try to create a style that sets the BorderThickness to 0 and apply it on each of your buttons. This approach works for control templates that bind the border thickness from their templated parent.
<Style x:Key="BorderlessButtonStyle" TargetType="{x:Type Button}" BasedOn="{StaticResource {x:Type Button}}">
<Setter Property="BorderThickness" Value="0"/>
</Style>
If this does not work or you want adapt the appearance of your buttons in detail, you have to extract and adapt the button style and control template.
Your custom control template does not work, because you did not apply it to the inner buttons and you should remove Content="{TemplateBinding Content}". Nevertheless, your button control template does not define any control states, so it will not be responsive at all.
You should copy the control template for Button from here, or extract it manually via Blend or Visual Studio. Then you can remove or the Border within it, change its thickness or color, so it will disappear. Moreover, you can adapt its various states to fit your desired style.
A notice on your design. It do not think that it is a good idea to nest buttons. Your control should either be a single button or a panel with two buttons in it, but that also only makes sense if they execute different actions in a related context, like split buttons do.
I want to instantiate two Controls (an Expander and a Button) from two ControlTemplates. They are docked in a Dockpanel (right and left). The Expander is visible and it works fine, but the Button isn't visible.
The ControlTemplate of the Button in App.xaml:
...
<ControlTemplate x:Key="OpenFileButton" TargetType="{x:Type Button}">
<Image Name="OpenFileButton" Source="F:\AudioNodeGUI_XAML\images\filebutton.jpg">
</Image>
</ControlTemplate>
...
And the instantiation in a usercontrol:
<Grid>
<Image Source="F:\AudioNodeGUI_XAML\images\FileInputNode.jpg"/>
<DockPanel Name="dock" Width="151" Height="20" Margin="27,53,122,139">
<Expander Name="expander" Template="{StaticResource FileExpander}" Height="20" Width="41" PreviewMouseLeftButtonUp="expand" DockPanel.Dock="Left">
<ListView Name="usedFiles" Background="Black" BorderBrush="Transparent" BorderThickness="0" Width="140" Height="120" Opacity="0.5">
</ListView>
</Expander>
<Button Name="OpenFileButton" Template="{StaticResource OpenFileButton}" DockPanel.Dock="Right" />
</DockPanel>
</Grid>
But the Button isn't visible, neither in the Designer (just the outline) nor in execution. What am I doing wrong?
I suspect that your issue is just incorrect path to the image file. Unfortunately you won't have any tip about this kind of error neither in designer nor in output window. However if you have ReSharper it should highlight the path to the file if it doesn't exist
I've used WPF and IDataErrorInfo in the past apps to display errors to the user via a controltemplate by putting an image in the adorner and adding a tooltip to the image like this;
<Style x:Key="textStyle" TargetType="TextBox">
<Setter Property="Validation.ErrorTemplate">
<Setter.Value>
<ControlTemplate>
<DockPanel LastChildFill="True">
<Border BorderBrush="Orange"
BorderThickness="2"
CornerRadius="4"
SnapsToDevicePixels="True">
<Border.Effect>
<DropShadowEffect BlurRadius="10"
ShadowDepth="0"
Color="Orange" />
</Border.Effect>
<DockPanel>
<Image Width="16"
Height="16"
Margin="-20,0,0,0"
HorizontalAlignment="Left"
VerticalAlignment="Center"
RenderOptions.BitmapScalingMode="HighQuality"
Source="{StaticResource imgError}"
ToolTip="{Binding ElementName=adornedElement,
Path=AdornedElement.(Validation.Errors).CurrentItem.ErrorContent}"
ToolTipService.ShowDuration="30000" />
<AdornedElementPlaceholder Name="adornedElement" />
</DockPanel>
</Border>
</DockPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
With the appropriate implementation of IDataErrorInfo in the ViewModel and setting Textbox in the view accordingly the image and tooltip are shown;
<TextBox Name="txt"
Grid.Column="0"
Height="40"
Background="Aqua"
Style="{StaticResource textStyle}"
Text="{Binding Path=Text,
UpdateSourceTrigger=PropertyChanged,
ValidatesOnDataErrors=True}" />
<TextBlock Grid.Column="1"
Height="40"
Background="AliceBlue"
Text="{Binding ElementName=txt,
Path=(Validation.Errors).CurrentItem.ErrorContent}" />
The above code displays correctly in my previous apps and shows the error in the image tooltip as confirmed by the Textblock.
However, in my current app which is built using Prism I can't get the Image to display. The TextBlock updates correctly and I can set the error to the TextBox tooltip via a style trigger without any issue. The problem is I can't seem to get the image (or anything else) to display in the Adorner. The Image is not shown and border is not changed.
The difference between previous apps and this is that the view is in a Region in a ContentControl and I've used dependency injection to inject the viewmodel into the view constructor and set the DataContext.
I can't figure out why this doesn't work when it did previously. I think I may need to include an AdornerDecorator somewhere but I'm perplexed as to where having tried it in a few places without success. Any ideas how I can ensure the Adorner is shown?
Used an AdornerDecorator to wrap the element containing the texbox and all works fine.
I am creating a container whose style will be used across the application. It essentially is a 'pop up' but won't spawn in a new window. The general structure of my app is one NavigationWindow and many pages. So I get started with the following Template, defined in my Resource Dictionary:
<ControlTemplate x:Key="RainbowModalTemplate" TargetType="{x:Type Control}">
<Canvas Height="540" Canvas.Left="492" Canvas.Top="296" Width="945">
<Border x:Name="Modal" Height="540" Width="945" Background="#ec2016" BorderBrush="White" BorderThickness="2" CornerRadius="15" Style="{DynamicResource RainbowModalBox}">
<Border.Clip>
<RectangleGeometry RadiusX="15" RadiusY="15" Rect="0,0,945,540"/>
</Border.Clip>
<Image Source="Resources/RainbowModal/rainbow.png" Height="247" Width="947" Margin="0,0,0,0" VerticalAlignment="Bottom" d:LayoutOverrides="Height" Stretch="UniformToFill" Canvas.Left="-2" Canvas.Top="293" ClipToBounds="True" />
</Border>
</Canvas>
</ControlTemplate>
So when I want to 'consume' this, I want to be able to implement this control but provide my own content inside, (buttons, text, etc). However because I am new to WPF I am unsure what control or controls to use, and what structure to lay this out as. Below is sample 'consumer' of the object. Someone will click a button in the application and that will set this objects' visibility to be Visible :
<Control x:Name="RequestMoreInfoModal" Template="{DynamicResource RainbowModalTemplate}" Canvas.Left="494" Canvas.Top="250" Visibility="Collapsed"></Control>
I know this probably isn't the most kosher way to do this, so I am open to suggestion. My specific concerns:
I know "Control" isn't the right type. But I don't know what is appropriate and it appears Canvas and other controls do not allow Templating. What control should I use?
how do I implement this Template and also allow the consumer to define their own content within the Template?
What I eneded up doing is using a ControlTemplate and ContentPresenter.
Here is the definition of the reusable content in my ResourceDictionary:
<ControlTemplate x:Key="RainbowModal" TargetType="ContentControl">
<Canvas>
<Border x:Name="Modal" Height="540" Width="945" Background="#ec2016" BorderBrush="White" CornerRadius="15" BorderThickness="2" Style="{DynamicResource RainbowModalBox}">
<Border.Clip>
<RectangleGeometry
RadiusX="{Binding CornerRadius.TopLeft, RelativeSource={RelativeSource AncestorType={x:Type Border}}}"
RadiusY="{Binding RadiusX, RelativeSource={RelativeSource Self}}"
Rect="0,0,945,540"/>
</Border.Clip>
<Canvas>
<Image Source="Resources/RainbowModal/rainbow.png" Height="247" Width="947" Margin="0,0,0,0" VerticalAlignment="Bottom" Stretch="UniformToFill" Canvas.Left="-2" Canvas.Top="293" ClipToBounds="True" />
<ContentPresenter/>
</Canvas>
</Border>
</Canvas>
</ControlTemplate>
And here is the 'consumption' of that content.
<ContentControl x:Name="RequestMoreInfoModal" Canvas.Left="489" Canvas.Top="122" Template="{StaticResource RainbowModal}" Visibility="Collapsed">
<Canvas>
<TextBlock FontSize="78" Foreground="White" Width="903" Canvas.Top="28" Canvas.Left="20" Height="298" Text="Scan your card to receive an email with more information." TextWrapping="Wrap" FontFamily="Serif72 Beta" TextAlignment="Center" />
<Button Width="250" Height="76" Content="CLOSE" Margin="350,350" Style="{DynamicResource PurpleInfoButton}" FontSize="28" Click="Button_Click_1" ></Button>
</Canvas>
</ContentControl>
I Wish the treeviewitem to overlap the other items when i mouse hover it.
To do this i made the parent element (in my case its Border) within the HierarchicalDataTemplate to have the ZIndex as 0 and changed this value to 1 when the user hovers the mouse in the HierarchicalDataTemplate.Triggers section
<HierarchicalDataTemplate DataType="{x:Type d:MyClass}">
<Border Name="brd" CornerRadius="5" BorderThickness="1" Padding="3" Margin="0,0,60,0" Panel.ZIndex="0" >
<StackPanel Orientation="Horizontal" Margin="0,0,0,0" >
<Image Source="../Images/icon.jpg" Height="30"></Image>
<TextBlock TextAlignment="Center" Text="{Binding Text}"
Margin="3,0,10,0" >
</TextBlock>
<Image Margin="0,0,3,0"
Source="../Images/Img1.jpg" Height="30" />
<Image Margin="0,0,0,0"
Source="../Images/Img2" Height="30"/>
</StackPanel>
</Border>
<HierarchicalDataTemplate.Triggers>
<Trigger SourceName="brd" Property="IsMouseOver" Value="True">
<Setter TargetName="brd" Property="Panel.ZIndex" Value="1"></Setter>
</Trigger>
</HierarchicalDataTemplate.Triggers>
</HierarchicalDataTemplate>
The whole idea to implement this was:
Whenever the user hovers the mouse over a treeviewitem, the item should overlap the other controls and should be completely visible. Example: if the item is a long text, then the user should not be forced to use the scroll bar, rather if he just points it the item should be overlapping the other controls to display the complete item.
But i couldn't achieve this using the above triggers.
Please help me doing this.
Did you try using a ToolTip? I didn't try it myself but after seeing this I'm convinced that it's possible to define a DataTemplate which can be used at this property so the item is shown the way you like.
I hope this helps.
