<!--데이터바인딩-->

 

<!--스크롤바가 움직일때 마다 위치를 label에 넣기-->

 

<!--ValueChanged에 이벤트를 걸고 C#에서 처리-->

<Label Name="label1" HorizontalAlignment="Center"/>

<ScrollBar Name="scroll1" Orientation="Horizontal" Margin="20" Minimum="1" Maximum="100"

LargeChange="10" SmallChange="1" ValueChanged="scroll1_ValueChanged"/>

 

<!--데이터바인딩 이용-->

<Label Name="label2" HorizontalAlignment="Center" Content="{Binding ElementName = scroll2, Path = Value}"/>

<Button FontSize="{Binding ElementName = scroll2, Path = Value}">버튼</Button>

<ScrollBar Name="scroll2" Orientation="Horizontal" Margin="20" Minimum="1" Maximum="100"

LargeChange="10" SmallChange="1" />

 

<TextBox Name="txt1"/>

<TextBox Name="txt2" Text="{Binding ElementName=txt1, Path=Text}"/>
