I'm trying to set an image inside a RadioButton like shown at https://learn.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/radiobutton
<RadioButton>
<RadioButton.Content>
<Image Source="icon.png"/>
</RadioButton.Content>
</RadioButton>
But in app it shows only the text "Xamarin.Forms.Image" instead of the image.
What is wrong? I just did it like in the example.
Please read the docs
However, on some platforms a RadioButton can display a View,
and
On Android, RadioButton objects will display a string-based representation of the View object that's been set as content:

I have a listview in my app (C# - UWP)
and in my DataTemplate i have a TextBlock that it Binding a text.
this is my code:
<TextBlock Text="{Binding Caption}" FontSize="11"/>
Now, how can i coloring all hashtags in the text? And clickable?
Note: all captions that binding this TextBlock is variable.
Like:
This is test #message for testing
Or
I like #German and #Russian language
I want change color #message, #German and #Russian and clickable feature in TextBlock
One option is to use a rich text box. Rich text box can render HTML like tags.
so you can have text like
<p> I am following the <a>#Russian-Language</a> <a>#azure</a> tutorials. </P>
Then anchor tags can have targets and they will be clickable. OR you can call a method on this hyperlink click.
Hope this helps you.
I made a control few months back called HashHandleTextBlock. The core concept of this is based on MarkdownTextBlock of UWP Community Toolkit.
Below is how you use controls.
<UnwantedControls:HashHandleTextBlock Text="{Binding ElementName=InputText, Path=Text}"
LinkForeground="DarkGray"
HashPrefix="https://twitter.com/hashtag/"
HandlePrefix="https://twitter.com/" />
You can also download the source from Github and modify control for your requirement.
I am new to XAML and C#
I have an icon created already in a project and and I have to use this icon whenever I select one of the option from the dropdown menu.
I made a stackpanel in XAML file
<StackPanel Name="stackPanelforIcon">
</StackPanel>
In the code behind file I have different cases for the dropdown menu.
case IconOnSelect:
?????? = IconList.NewIcon;
This NewIcon is the one already created and I am using the source also for this
using IconProject.Iconlists;
On writing IconList.NewIcon I am not getting any error, it is referenced correctly.
What should I write at ?????? to reference it. Is there any other way apart from using stackPanel to include an icon
A StackPanel cannot show an icon on it's own. You need a control for it, for example an Image.
<StackPanel Name="stackPanelforIcon">
<Image x:Name=theImage" />
</StackPanel>
Then you can use your Icon in your code behind like this:
this.theImage.Source = IconList.NewIcon;
You may need to convert your value, you never said what type it actually is.
Please note that using code-behind is not the preferred way with WPF. Using MVVM is way easier and more natural working with WPF, using code-behind you will fight WPF all the way. Using MVVM, this could be:
<StackPanel Name="stackPanelforIcon">
<Image Source="{Binding CurrentImage}" />
</StackPanel>
with your ViewModel having a property called CurrentImage that you would set when you want to change it. Don't forget to implement INotifyPropertyChanged for the changes to take effect though.
Any one knows how to show the slider tool tip on Windows Phone 8.1 WinRT? I have checked the property IsThumbToolTipEnabled but no tool tip is shown. I couldn't find any resources on how to do this on phone. Any clue?
Set a custom template and use the tooltipservice api.
First, edit the style for a slider. Next find the <Thumb> Element. This code will work and show the text, and you can use binding for the text value.
<Thumb>
<ToolTipService.ToolTip>
<TextBlock Text="Your text"/>
</ToolTipService.ToolTip>
</Thumb>

I have a chat window where each message is a TextBlock. I want to be able to select the text inside my TextBlocks. Google says to use a TextBox instead, which I cannot do because they do not support runs, which I am using to create hyperlinks inside my messages. What options do I have?
Check out the RichTextBox implementation for WPF.
How about making an CustomContentControl with TextBox (with selection style) and a Link in it and play with visibility based on content. Some thing like
<myControls:CustomContentControl>
<Grid>
// play with visibilty depending on content.
<CustomLink/>
<TextBox Style="{StaticResource SelectionStyle}"/>
</Grid>
</myControls:ContentControl>
