I have taken a break from WPF for about a year and I am stumped by this simple problem. I swear there was an easy way to tell a label to focus to another control when it is clicked.
<StackPanel>
<Label Target="TextBox1">Label Text</Label>
<TextBox Name="TextBox1" />
</StackPanel>
When the user clicks on "Label Text" I want the TextBox to receive focus. Is this possible?
You should make use of the Target property:
<Label Content="_Stuff:" Target="{x:Reference TextBox1}"
MouseLeftButtonUp="Label_MouseLeftButtonUp"/>
<TextBox Name="TextBox1" />
private void Label_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
if (e.ClickCount == 1) //Note that this is a lie, this does not check for a "real" click
{
var label = (Label)sender;
Keyboard.Focus(label.Target);
}
}
The whole point of using a Label in the first place instead of a TextBlock is to make use of its associative functionality, see the reference on MSDN .
About my note, i asked a question about how to get a real click over here , if you are curious.
I found the code I used to use for this and figured I would share it in case it is useful for anyone else.
public class LabelEx : Label
{
protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e)
{
if (Target != null)
{
Target.Focus();
}
}
}
can't you do that with the shortcut key combination
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<Label Target="{Binding ElementName=textbox1}" Content="_Name"/>
<TextBox Name="textbox1" Height="25" Grid.Column="1" VerticalAlignment="Top"/>
</Grid>
Based on reading WPF label counterpart for HTML "for" attribute , you'd need an attached behavior to do that.
