I'm developing an UWP app and i'm trying to add two buttons and a textblock for each image that binded.
I'm binding the images in XAML like this; (Updated with the full code)
<GridView Name="display"
Margin="30,100,30,5"
Foreground="#FFFFFF"
IsItemClickEnabled="True"
ItemClick="display_ItemClick"
ItemsSource="{Binding}">
<GridView.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical">
<Image Width="240"
Height="240"
Source="{Binding Path=Image}" />
<StackPanel Name="buttonPanel"
Orientation="Horizontal"
Margin="0,-45,10,0"
HorizontalAlignment="Center">
<Button Name="button_minus"
Content="-"
Width="40"
Height="30"
Click="eksi_click"
FontWeight="Bold">
<Button.Background>
<ImageBrush ImageSource="Assets/btn2.png" Stretch="Fill" />
</Button.Background>
</Button>
<Border Background="White" CornerRadius="10" Height="30">
<TextBlock x:Name="popupNumber"
Width="50"
Height="25"
Margin="0,6,0,0"
Text="{Binding Path=numberOfCopy}"
TextAlignment="Center">
</TextBlock>
</Border>
<Button Name="button_plus" Content="+" Width="40" Height="30" Click="artı_Click" FontWeight="Bold">
<Button.Background>
<ImageBrush ImageSource="Assets/btn2.png" Stretch="Fill" />
</Button.Background>
</Button>
</StackPanel>
</StackPanel>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
I added a stackpanel that contains the Buton-TextBlock-Button format in the seciton of code that i commented out. When i do this, some buttons are not working and i don't actually know is it the best way to do my task.
When i launch the program, some buttons are not available to click. I can see them in the UI but i can't click them. The most awkward thing is only in a specific area on the UI, buttons are unavailable.
My click events are just fine, i have some binding issues, i am wondering is it the proper way to to something like that. Is it the way i am using causes the binding problem?
In in each TextBlock the values should be different for each image and i can't access buttons and textblocks in .cs file because they are in DataTemplate. So i might be doing this in a wrong way.
So do you have any solutions for adding buttons and textblocks for each binded image in Datatemplate? I'm not sure my way is the best way.
Any help would be greatly appreciated.
Thanks.

I tried using a textbox inside a WPF Material Design transitioner slide. The textbox is visible even when changing slides.
A dotted line from the textbox on the next slide is visible, and viceversa.
Has anyone else encountered this issue? Is there any workaround I could use?
This is the xaml I used. I am using the transitioner control although I believe the flipper control causes a similar effect when used with textboxes.
<Grid>
<materialDesign:Transitioner SelectedIndex="0">
<materialDesign:TransitionerSlide>
<StackPanel HorizontalAlignment="Center">
<TextBlock Text="Hello, this is my first page!" Margin="10"/>
<TextBox materialDesign:HintAssist.Hint="Type your first text here!" Margin="10"/>
<Button Command="{x:Static materialDesign:Transitioner.MoveNextCommand}" Content=">" HorizontalAlignment="Center" Margin="10"/>
</StackPanel>
</materialDesign:TransitionerSlide>
<materialDesign:TransitionerSlide>
<StackPanel HorizontalAlignment="Center">
<TextBlock Text="Hello, this is my 2nd page!" Margin="15"/>
<TextBox materialDesign:HintAssist.Hint="Type your second text here!" Margin="15"/>
<Button Command="{x:Static materialDesign:Transitioner.MovePreviousCommand}" Content="<" HorizontalAlignment="Center" Margin="15"/>
</StackPanel>
</materialDesign:TransitionerSlide>
</materialDesign:Transitioner>
</Grid>
I believe the issue might lie in the dotted line that appears when a textbox is disabled, so possibly by removing that, the textbox would no longer show through slides. But that's just my guess.
Any help is appreciated!
For the best approach, please refer to this answer.
Try to add the following implicit style to your App.xaml or window:
<Style TargetType="materialDesign:BottomDashedLineAdorner">
<Setter Property="Visibility" Value="Collapsed" />
</Style>
I try several ways and I found solution
please set BorderThickness="0" in textboxes like this
<TextBox materialDesign:HintAssist.Hint="Type your second text here!" Margin="10" BorderThickness="0"/>
Wrapping the offending control in:
<AdornerDecorator>
</AdornerDecorator>
seems to work.
Hi problem is in your margin , please set all your margins to 10 like this
<Grid>
<materialDesign:Transitioner SelectedIndex="0">
<materialDesign:TransitionerSlide>
<StackPanel HorizontalAlignment="Center">
<TextBlock Text="Hello, this is my first page!" Margin="10"/>
<TextBox materialDesign:HintAssist.Hint="Type your first text here!" Margin="10"/>
<Button Command="{x:Static materialDesign:Transitioner.MoveNextCommand}" Content=">" HorizontalAlignment="Center" Margin="10"/>
</StackPanel>
</materialDesign:TransitionerSlide>
<materialDesign:TransitionerSlide>
<StackPanel HorizontalAlignment="Center">
<TextBlock Text="Hello, this is my 2nd page!" Margin="10"/>
<TextBox materialDesign:HintAssist.Hint="Type your second text here!" Margin="10"/>
<Button Command="{x:Static materialDesign:Transitioner.MovePreviousCommand}" Content="<" HorizontalAlignment="Center" Margin="15"/>
</StackPanel>
</materialDesign:TransitionerSlide>
</materialDesign:Transitioner>
</Grid>
I hope it help you
I want to create a button using a image as background and on top of the background I want to place my text.
I tried something like this:
<Button Style="{StaticResource ImageButtonStyle}">
<StackPanel>
<TextBlock Text="test"></TextBlock>
<Image Source="ms-appx:///Skins/Images/buton.png" Stretch="None" />
</StackPanel>
</Button>
The text will not be centered correctly.
<Button Style="{StaticResource ImageButtonStyle}">
<StackPanel>
<TextBlock Text="test"></TextBlock>
<Label Padding="0">My Button Text</Label>
</StackPanel>
</Button>
The control Label doesn't exists.
How do I center correctly my text on the image in my first attempt?
Do you know a better way?
You should use a grid instade the stackpanel. Try something like this:
<Button >
<Grid>
<Image Source="..." Stretch="None" />
<TextBlock Text="test" VerticalAlignment="Center" HorizontalAlignment="Center"/>
</Grid>
</Button>
I'm new in XAML for Windows Phone 8.1 and have some troubles with
making a Stackpanel clickable
collapse Item, when clicked
My work so far looks like that:
And the Code to that (please correct me, if there are major flaws):
<Border CornerRadius="15" Background="#FF595656" Margin="0" Grid.ColumnSpan="2" Height="80">
<StackPanel Orientation="Horizontal">
<StackPanel Width="20" HorizontalAlignment="Left" VerticalAlignment="Top" />
<StackPanel HorizontalAlignment="Left" Height="80" Margin="0,0,0,0" VerticalAlignment="Center" Width="51">
<Image HorizontalAlignment="Left" Height="51" Margin="0,15,0,0" Width="51" Source="Assets/fish.png" Stretch="Fill" RenderTransformOrigin="2.307,0.881" VerticalAlignment="Center"/>
</StackPanel>
<StackPanel Width="10" HorizontalAlignment="Left" VerticalAlignment="Top" />
<StackPanel HorizontalAlignment="Left" Height="80" Margin="0" VerticalAlignment="Top" Width="310">
<TextBlock HorizontalAlignment="Left" Height="25" Margin="0,20,0,0" TextWrapping="Wrap" Text="Entry 1" Width="310" VerticalAlignment="Top" FontSize="18" Foreground="Black" FontWeight="Bold"/>
<TextBlock HorizontalAlignment="Left" Height="17" Margin="0" TextWrapping="Wrap" Text="Short description Entry 1" Width="310" VerticalAlignment="Top" Foreground="#FF0097FF"/>
</StackPanel>
</StackPanel>
</Border>
This code will later be wrapped inside a ListBox with Image, Entry 1 and the short description being bound:
<ListBox x:Name="ListBox1" Margin="0"
Width="400" Height="200" HorizontalAlignment="Left"
ItemsSource="{Binding}" Grid.Row="1" VerticalAlignment="Top" Grid.ColumnSpan="2" >
<ListBox.ItemTemplate>
<DataTemplate>
// the code above
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
So my question is:
How can I make a nice looking expansion/collapse of each Item in the ListBox, whenever I click on it?
Thank you very much in advance.
The real question is here is what do you want it to collapse to? There are too many possible ways to collapse some visual data item. Do you just want to change the height of the item or do you want some fancy animation that collapse some property?
If the height is what you're looking for it's pretty easy. Just attach an Tap Event on that Border of yours. On a sidenote, you probably want to edit the ItemContainerStyle to have <Setter Property="HorizontalContentAlignment" Value="Stretch"/> so the Listbox will stretch across the screen, otherwise imho it's un-useable.
<ListBox.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Red" BorderThickness="0,1" Tap="Border_Tap">
<StackPanel>
<!--- rest of template --->
</StackPanel>
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
Then calculate the Minimum height you want to show (make sure it's actually useable, meaning... I can Tap on it again to show the whole thing without using a Mag Glass).
private void Border_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
int minHeight = 40; // change to whatever you want
Border b = sender as Border;
if (b.ActualHeight > minHeight)
{
b.Height = minHeight;
}
else
{
b.Height = double.NaN; // this will change the height back to Auto, showing everything
}
}
Code In Action
This is just a quick solution to your question. Some people on here would rather have you create a StoryBoard Animation on the Height Property of the Selected state in the VisualStateManager. If you reword or create a new question explicitly stating you want a VisualStateManager solution, I will provide you one as well. Good luck.
Can someone give me an example of how to style a button with XAML hat has three states (hover, normal, pressed). i want the whole area of the button to be covered with an image (one for each of the three different states) and i want text to be on top that also has three different colors for the different states. i have something like this already (without the color states on the textblock). the problem i'm having at this point is that the textblock is blocking the input events for the button undernearth (i also haven't implemented the color changes for the textblock....
current code:
<DataTemplate x:Name="SubjectItemTemplate">
<Canvas Width="225" Height="225">
<Button Canvas.Left="0" Canvas.Top="0"
Command="{Binding ElementName=LayoutRoot, Path=DataContext.NavigateToUnitsPage}"
CommandParameter="{Binding}">
<Button.Template>
<ControlTemplate>
<Grid Background="{Binding LightThemeColor}" Width="205" Height="205">
<controls:ImageButton HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0,0,0,0"
NormalStateImageSource="{Binding ImageUriNormal}"
HoverStateImageSource="{Binding ImageUriHover}"
PressedStateImageSource="{Binding ImageUriPressed}" Command="{Binding ElementName=LayoutRoot, Path=DataContext.NavigateToUnitsPage}"
CommandParameter="{Binding}"/>
<TextBlock Text="{Binding Name}" FontSize="18" TextWrapping="Wrap" TextAlignment="Center" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0,168,0,0" />
</Grid>
</ControlTemplate>
</Button.Template>
</Button>
</Canvas>
</DataTemplate>
The reason that the ImageButton events are not being handled as expected with the TextBlock is because the TextBlock is located in-line with the ImageButton and not contained inside the ImageButton. To change this, the TextBlock has to be placed inside the ImageButton.
<controls:ImageButton HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0,0,0,0"
NormalStateImageSource="{Binding ImageUriNormal}"
HoverStateImageSource="{Binding ImageUriHover}"
PressedStateImageSource="{Binding ImageUriPressed}" Command="{Binding ElementName=LayoutRoot, Path=DataContext.NavigateToUnitsPage}" CommandParameter="{Binding}" >
<TextBlock Text="{Binding Name}" FontSize="18" TextWrapping="Wrap" TextAlignment="Center" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0,168,0,0" />
</controls:ImageButton>
So I have this Xaml inside a ListBox Item Template:
<ListBox.ItemTemplate>
<DataTemplate>
<Grid Height="22" Width="Auto">
<Image Margin="-2,0,0,0" Source="{Binding Path=ADsPath, Converter={StaticResource ImxConverter}}" HorizontalAlignment="Left" Width="22" />
<TextBlock Margin="20,3,0,0" Text="{Binding Path=DisplayValue}" Width="Auto" />
<Rectangle Fill="White" Stroke="White" Margin="-2,0,-2,0.5" VerticalAlignment="Bottom" Height="1" Width="Auto" />
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
The idea is that the rectangle, provides a thin white line across the bottom of the entire ListBox Item; however, with the Xaml above, it only extends as long as the text, not to the full width of the ListBox.
Setting your width to Auto basically tells it to only be large enough to fit everything inside. I think you need to set your Grid's HorizontalAlignment to Stretch for it to work properly.
Edit:
I did a small sample app. Here's how I would do what you are trying to do:
On your actual listbox, I would have the HorizontalContentAlignment property set to Stretch
and
I would change your Grid to a DockPanel:
<ListBox.ItemTemplate>
<DataTemplate>
<DockPanel Height="22" HorizontalAlignment="Stretch">
<Rectangle Fill="White" Stroke="White" Margin="-2,0,-2,0.5" DockPanel.Dock="Bottom" Height="1"/>
<Image Margin="-2,0,0,0" Height="20" DockPanel.Dock="Left" Width="22" />
<TextBlock Margin="20,3,0,0" Text="Daniel Manning" DockPanel.Dock="Left"/>
</DockPanel>
</DataTemplate>
</ListBox.ItemTemplate>
Have you tried removing Width="Auto"? Auto is saying "only make me as big as I need to be" which, in your case, is determined by the length of the text. The default is "Stretch" which means "hey container, do me a favor and make me as wide as you are".
