WPF 3.5 SP1 feature: StringFormat

  • Artigo

One of the new features in 3.5 SP1 is stringformat. The usage is pretty simple. So following are simple snippets showing its use

<TextBox Text="{Binding Path=Double, StringFormat=F3}"/>

<TextBox Text="{Binding Path=Double, StringFormat=Amount: {0:C}}"/>

<TextBox Text="{Binding Path=Double, StringFormat=Amount: \{0:C\}}"/>

<TextBox>

  <TextBox.Text>

    <Binding Path="Double" StringFormat="{}{0:C}"/>

  </TextBox.Text>

</TextBox>

 

<TextBox>

  <TextBox.Text>

    <MultiBinding StringFormat="{}{0:F2} = {1:D}">

      <Binding Path="Double" />

      <Binding Path="Date"/>

    </MultiBinding>

  </TextBox.Text>

</TextBox>

<TextBox>

  <TextBox.Text>

    <Binding Path="Date" StringFormat="{}{0:MM/dd/yyyy}"/>

  </TextBox.Text>

</TextBox>

<ListBox Background="Beige" ItemStringFormat="F3">

  <sys:Double>1.11122</sys:Double>

  <sys:Double>2.11345</sys:Double>

</ListBox>

<GroupBox Background="AliceBlue" Content="{Binding Path=Double}" ContentStringFormat="F4"

          Header="{Binding Path=Double}" HeaderStringFormat="F5"/>

<Label Content="{Binding Path=Double}" ContentStringFormat="{}{0:E2}"/>

<GridView>

  <GridViewColumn Header="Date"

           DisplayMemberBinding="{Binding XPath=Date, StringFormat=D}" />

 This feature makes life a lot more easier when it comes to formatting.. So have fun with it.

    Nice post.  Like that multi-binding example. I have not tried the new SP1 yet because I'm doing Silverlight and don't want to give that up until the tools release. Did you try this with the decimal data type instead of double?   I had to write a special converter to handle the decimal data type because the "$" was blowing up the type converter for a decimal data type.  My converter strips out the "$" before the string to decimal conversion takes place. Did you try this with nullable properties on the data object.  I wrote a series of converters to handle nullable data types. Cheers, Karl

    Karl, decimals work fine and nullable values also seem fine :)

    This is good news. This is what I was looking for in the original WPF. Having to create an IValueConverter to do simple formatting was a pain. It looks like there are a few different ways to escape the {} characters?

    Would it be too much trouble to post an example that actually works?

    Hi! I like the string.format feature. But there is one problem: If the value you are binding to is null the formated string will show {DependencyProperty.UnsetValue}. I would expect it to show simply nothing. Will that be fixed in the final release?
