is it possible to get a watermarks passwordbox in WinRt? It is no problem to get a textbox with a watermark, but I don't know a toolkit where I can get a password box with a watermark.
How can I implement one for myself?
Take a look on WinRT XAML Toolkit.
They also have
WatermarkTextBox
WatermarkPasswordBox
By yourself you can implement your own controls:
in .xaml:
<Border x:Name="brdPassword" Margin="5,0,5,10" BorderThickness="2" BorderBrush="White" CornerRadius="5" Grid.Row="0"
Background="White" Height="50" VerticalAlignment="Stretch">
<Grid>
<TextBox x:Name="PasswordWatermark" TextWrapping="Wrap"
Text="Watermark" Foreground="#FFC4C4C4" IsHitTestVisible="False"
Background="{x:Null}" BorderThickness="0" Padding="0,-10"
FontSize="26.667" />
<PasswordBox x:Name="pbPassword" LostFocus="PasswordLostFocus"
GotFocus="PasswordGotFocus" Background="{x:Null}"
FontSize="26.667" Margin="0,-12,0,-9" VerticalAlignment="Center"
BorderThickness="0" Opacity="0" />
</Grid>
</Border>
in .cs
private void PasswordLostFocus(object sender, RoutedEventArgs e)
{
CheckPasswordWatermark();
}
private void CheckPasswordWatermark()
{
var passwordEmpty = string.IsNullOrEmpty(pbPassword.Password);
PasswordWatermark.Opacity = passwordEmpty ? 100 : 0;
pbPassword.Opacity = passwordEmpty ? 0 : 100;
}
private void PasswordGotFocus(object sender, RoutedEventArgs e)
{
PasswordWatermark.Opacity = 0;
pbPassword.Opacity = 100;
}
Hope it's help
I don't think we can put watermark in the Password control.
You can put a TextBox with wartermark in the same row and same column with the Password control, then handle the two controls' GotFocus and LostFocus events to make the control Visible or Collapsed.
There is no toolkit yet which provides watermarked password box. However this may help:-

I am searching for this long time and i couldn't get it.
I have a Long list selector in my windows phone 8 project.
How can i manage the button event in each item in the data template? I need to get the selected item in that button event.
Code snippet shown below. Please help.
try this
// in your button click event type this code
var selectedValue = ((sender as Button).dataTemplate;
or
var selectedValue = ((sender as Button).dataTemplate as SbCaDd).AcNo;
If you want to access the dataContext then try this one.
XAML
<phone:LongListSelector Grid.Row="1"
Name="llsMsg"
LayoutMode="List"
VirtualizingStackPanel.VirtualizationMode="Recycling">
<phone:LongListSelector.ItemTemplate>
<DataTemplate>
<StackPanel>
<Grid>
<TextBlock Text="{Binding}"
Foreground="Black" />
<Button Content="View Details"
Width="200"
Click="Button_Click"/>
</Grid>
</StackPanel>
</DataTemplate>
</phone:LongListSelector.ItemTemplate>
</phone:LongListSelector>
C#
private void Button_Click(object sender, RoutedEventArgs e)
{
var dataContext = (sender as Button).DataContext;
var dataContext = (sender as Button).DataContext as YourDataModel;
}
I have the following XAML code for Windows Phone 8.1 (non SilverLight):
<Grid>
<ToggleButton Name="TogBtn" VerticalAlignment="Center" HorizontalAlignment="Center" Checked="ToggleButton_OnChecked">
<SymbolIcon Symbol="play"></SymbolIcon>
</ToggleButton>
</Grid>
The output of the above code is:
How can I change the icon to a stop icon when the toggle button is checked and then back to play icon when unchecked?
I thought this would be easy to find through Google, but apparently not.
Please change your XAML to this:
<Grid>
<ToggleButton x:Name="TogBtn" HorizontalAlignment="Center" VerticalAlignment="Center" Checked="ToggleButton_Checked" Unchecked="ToggleButton_Unchecked">
<SymbolIcon Symbol="Play"></SymbolIcon>
</ToggleButton>
</Grid>
And please add this to your .cs file:
private void ToggleButton_Checked(object sender, RoutedEventArgs e)
{
TogBtn.Content = new SymbolIcon(Symbol.Stop);
}
private void ToggleButton_Unchecked(object sender, RoutedEventArgs e)
{
TogBtn.Content = new SymbolIcon(Symbol.Play);
}
That should do the job!
I have an image control in my main page and the code is as follows:
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<StackPanel HorizontalAlignment="Left" Height="597" VerticalAlignment="Top" Width="440">
<Image x:Name="hinh1" Height="488" Stretch="Fill"/>
<ProgressBar Name="loading" Height="10" IsIndeterminate="True" Visibility="Collapsed"/>
</StackPanel>
</Grid>
and in code behind i have this code :
Uri hinh = new Uri
("http://taigamejar.net/wp-content/uploads/2014/01/Hinh-Anh-Dep-5.jpg", UriKind.Absolute);
hinh1.Source = new BitmapImage(hinh);
While waiting for the image to load, I want to call progress bar run to inform the user that it is loading. Once the the image has loaded, the progress bar should disappear. How can I do this?
If I were you, I would prefer to use , not ProgressBar.
So, I'll give
protected override void OnNavigatedTo(NavigationEventArgs e)
{
loading.IsActive = true;
Uri hinh = new Uri
("http://taigamejar.net/wp-content/uploads/2014/01/Hinh-Anh-Dep-5.jpg", UriKind.Absolute);
hinh1.Source = new BitmapImage(hinh);
hinh1.ImageOpened+=hinh1_ImageOpened; //loadingbar will be disappear when this triggered
}
private void hinh1_ImageOpened(object sender, RoutedEventArgs e)
{
loading.IsActive = false; //this will disable the progressring.
}
And XAML:
<StackPanel HorizontalAlignment="Left" Height="597" VerticalAlignment="Top" Width="400">
<Image x:Name="hinh1" Height="488" Stretch="Fill" ImageOpened="hinh1_ImageOpened"/>
<ProgressRing Name="loading" Height="109" IsActive="True" />
</StackPanel>
If you don't have WP8.1 SDK yet, you can get ProgressRing here: http://www.onurtirpan.com/onur-tirpan/english/windows-phone-english/using-progressring-in-windows-phone/
I have a XAML:
<phone:Pivot Name="pivot" SelectionChanged="pivot_SelectionChanged">
<phone:Pivot.ItemTemplate>
<DataTemplate>
<ViewportControl Name="viewport">
<Canvas Name="canvas">
<Image Name="image"
RenderTransformOrigin="0,0"
CacheMode="BitmapCache"
Source="{Binding ImageSource}">
<Image.RenderTransform>
<ScaleTransform x:Name="xform"/>
</Image.RenderTransform>
</Image>
</Canvas>
</ViewportControl>
</DataTemplate>
</phone:Pivot.ItemTemplate>
</phone:Pivot>
Can I get current ViewportControl, Canvas, etc for selected item? For example
private void pivot_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
//get ViewportControl, Canvas, etc
}
Not necessarily with SelectionChanged, may have other solutions?
Yes, but you have to search for them. You need to use VisualTreeHelper and hunt for children of the desired type.
Or you can have some mapping in the code-behind for all controls and the parent pivot items.
I may be approaching this all wrong, so tell me if you have an alternative suggestions.
I'm making an app for windows RT that will have a bunch of text blocks displayed to the user, for example character stats.
The user will see:
Str: 10
Con: 10
Dex: 10
and so on.
I want them to be able to fill these in, then have a select view values calculated based on the result.
My though was to click an "Edit" button at the top and toggle some text boxes over each editable text block.
When trying to set this up using "Blend for Visual Studio" I can't seem to make a text box that is smaller than 49x34 (much larger than my text blocks).
I was going to find a way to generate a text box for each text block (using its dimensions) on button click, but since they will always be the same and there will be a lot of them I was trying to make them static via blend.
I'm pretty new to XAML, and I can't seem to find a good example of people setting up editable fields like this, so how should I make a bunch of static fields have editable text boxes?
I would create both the TextBox and TextBlock overlays in XAML, and place them directly on top of each other in a Grid, using Horizontal and Vertical alignments to "Center" to ensure that the text is always completely lined up. I would also use static Widths to ensure that the columns line up well.
From there, you can directly bind the Visibility to some boolean "IsEditing" property, to make sure that only one of the controls are shown at a time.
<StackPanel Orientation="Horizontal">
<TextBlock Text="Str: " Width="40" VerticalAlignment="Center" />
<Grid Width="40" VerticalAlignment="Center">
<TextBlock Text="{Binding Strength}"
Visibility="{Binding IsEditing, Converter={StaticResource BooleanToInvisibilityConverter}}"
VerticalAlignment="Center"
HorizontalAlignment="Center" />
<TextBox Text="{Binding Strength}"
Visibility="{Binding IsEditing, Converter={StaticResource BooleanToVisibilityConverter}}"
VerticalAlignment="Center"
HorizontalContentAlignment="Center" />
</Grid>
</StackPanel>
Somewhere along the way you'll have to define your "BooleanToVisibility" and "BooleanToInvisiblity" converter resources. I like this implementation by Diedrik Krols. It's nice and simple, with the option to invert.
You might want to use a style for a TextBox, which changes depending on whether or not the "IsReadOnly" property is true or not.
When IsReadOnly is true, you can set the BorderBrush and Background to Transparent, thus making it look like a normal textblock.
In this way, you don't have to overlay TextBlocks and TextBoxes; just use TextBox controls by themselves, and toggle the "IsReadOnly" property when you click the Edit button.
In your resources:
<Style x:Key="MyEditableField" TargetType={x:Type TextBox}>
<Style.Triggers>
<DataTrigger Binding="{Binding IsReadOnly, RelativeSource={RelativeSource Self}}" Value="True">
<Setter Property="BorderBrush" Value="Transparent" />
<Setter Property="Background" Value="Transparent" />
</DataTrigger>
</Style.Triggers>
</Style>
And here's one of your editable fields:
<StackPanel Orientation="Horizontal">
<TextBlock Text="Str: " />
<TextBox Style="{StaticResource MyEditableField}"
Text="{Binding Strength}"
IsReadOnly="{Binding IsEditingDisabled}" />
</StackPanel>
Late answer, but who wants can also create a custom editable textbox, its pretty easy actually here is the code (obviously you can modify it for your own needs)
public class EditableTextBox : TextBox
{
public EditableTextBox()
{
this.BorderBrush = new SolidColorBrush(Colors.Black);
}
protected override void OnTapped(TappedRoutedEventArgs e)
{
this.IsReadOnly = false;
SetEditingStyle();
base.OnTapped(e);
}
protected override void OnDoubleTapped(DoubleTappedRoutedEventArgs e)
{
this.IsReadOnly = false;
SetEditingStyle();
base.OnDoubleTapped(e);
}
protected override void OnLostFocus(RoutedEventArgs e)
{
this.IsReadOnly = true;
SetReadonlyStyle();
base.OnLostFocus(e);
}
public void SetReadonlyStyle()
{
this.BorderBrush.Opacity = 0;
this.Background.Opacity = 0;
}
public void SetEditingStyle()
{
this.BorderBrush.Opacity = 1;
this.Background.Opacity = 1;
}
}

Using a property to toggle edit mode between view AND viewmodel is a bad design approach you should use events and command binding to communicate changes of states like this between view and viewmodel.
Here is an article that describes the principle in an MVVM compliant way:
http://www.codeproject.com/Articles/802385/A-WPF-MVVM-In-Place-Edit-TextBox-Control
Please have a look and tell me what you think.
This builds off of BTownTKD's solution, but as I really do prefer as much WPF of a solution as possible here is a bit of a modification, in my case I'm trying to modify the name of a tab control.
My view model has the following code:
private bool _isEditingName = false;
public bool IsEditingName
{
get
{
return _isEditingName;
}
set
{
_isEditingName = value;
OnPropertyChanged();
}
}
public ICommand StartEditing
{
get
{
return new DelegateCommand(() =>
{
IsEditingName = true;
});
}
}
public ICommand EndEditing
{
get
{
return new DelegateCommand(() =>
{
IsEditingName = false;
});
}
}
Next is my view that has the data template for the tab (not the content just the tab):
<TabControl ItemsSource="{Binding Items}" SelectedItem="{Binding ActiveItem}">
<TabControl.ItemTemplate>
<DataTemplate>
<Grid VerticalAlignment="Center">
<TextBlock x:Name="TabName" Text="{Binding Name}" Visibility="{Binding IsEditingName, Converter={StaticResource InvertedBoolToVisConverter}}" VerticalAlignment="Center" HorizontalAlignment="Stretch" TextAlignment="Left">
<TextBlock.InputBindings>
<MouseBinding MouseAction="LeftDoubleClick" Command="{Binding StartEditing}" />
</TextBlock.InputBindings>
</TextBlock>
<TextBox Text="{Binding Name}" Visibility="{Binding IsEditingName, Converter={StaticResource BoolToVisConverter}}" VerticalAlignment="Center" HorizontalContentAlignment="Stretch" TextAlignment="Left" IsVisibleChanged="TextBox_IsVisibleChanged">
<i:Interaction.Triggers>
<i:EventTrigger EventName="LostFocus">
<i:InvokeCommandAction Command="{Binding EndEditing}" />
</i:EventTrigger>
</i:Interaction.Triggers>
<TextBox.InputBindings>
<KeyBinding Key="Enter" Command="{Binding EndEditing}" />
</TextBox.InputBindings>
</TextBox>
</Grid>
</DataTemplate>
</TabControl.ItemTemplate>
</TabControl>
And last but not least, I wanted a double click to put me in edit mode, and to auto focus on the textbox and select all of the content for immediate typing. None of the xaml solutions were as clean as a simple code behind so I finally just decided on adding this to the textbox on visibility changed handler:
private void TextBox_IsVisibleChanged(object sender, System.Windows.DependencyPropertyChangedEventArgs e)
{
var box = sender as TextBox;
if (box != null)
{
if ((bool)e.NewValue)
{
box.Focus();
box.SelectAll();
}
}
}
Out of all of the solutions I found, this was by far my favorite. Thanks everyone for your posts!! Helped me find a really good overall solution to my problem!
