Is it possible to make text wrap inside of a border? WPF-CodePudding

I have something like this:

<ControlTemplate>
                <StackPanel Orientation="Horizontal">
                    <!--Icon-->
                        <Ellipse Width="30" Height="30" Margin="10,0,0,-5">
                        <Ellipse.Fill>
                            <ImageBrush ImageSource="{Binding ImageSource}"
                                        RenderOptions.BitmapScalingMode="Fant"/>
                        </Ellipse.Fill>
                    </Ellipse>
                    
                    <!--Surround Info-->
                    <StackPanel>
                        <StackPanel Orientation="Horizontal">
                            <Label Content="{Binding Name}"
                                      Foreground="{Binding UserNameColor}"
                                      FontWeight="SemiBold"
                                      VerticalAlignment="Center"
                                      Margin="0,0,-5,0"/>
                            <Label Content="{Binding Date}"
                                      Foreground="White"
                                      FontWeight="SemiBold"
                                      FontSize="8"
                                      VerticalAlignment="Center"
                                      Margin="0,0,-5,0"/>
                        </StackPanel>
                        
                        <!--Message-->

                        
                        <Border VerticalAlignment="Center" CornerRadius="10 15 15 0" Margin="2 2 88 3" Background="LightSlateGray">
                            <TextBlock Foreground="White" Margin="7" TextWrapping="Wrap" FontWeight="SemiBold" Text="{Binding Content}"/>
                        </Border>
                    </StackPanel>
                </StackPanel>
            </ControlTemplate>

and I need the textblock to wrap with the text inside but I don't know how to do so without giving the border width which I don't want

I want to achieve something like that:

CodePudding user response：

You seem to be using StackPanels inside of StackPanels. There is a known issue where StackPanel will receive resize event of it's parent but only when the size increases. Reference:
