Public Property ContentStringFormat As String
A composite string that specifies how to format the contents of the TabItem objects if they are displayed as strings.
The following example binds a TabControl to a collection of Student
objects. The Student
class has a Name
property, a collection of Course
objects, and implements the IFormattable.ToString method to return either the Name
of the student or a string that lists the student's courses. The example uses HeaderedContentControl.HeaderStringFormat to put a student's name in the Header of each TabItem (which inherits from HeaderedContentControl), and the ContentStringFormat to display the course list for each student in the Content of the TabItem.
<Grid>
<Grid.Resources>
<src:Students x:Key="Students"/>
<Style TargetType="TabItem">
<Setter Property="HeaderStringFormat" Value="n"/>
<Setter Property="FontFamily" Value="Lucida Sans Unicode"/>
<Setter Property="Foreground" Value="Green"/>
<Setter Property="FontWeight" Value="Bold"/>
</Style>
</Grid.Resources>
<TabControl ItemsSource="{StaticResource Students}"
FontFamily="Lucida Console" Foreground="Navy"
ContentStringFormat="cl"/>
</Grid>
The following example implements the IFormattable.ToString method to return either the Name
of the student or a string that lists the student's courses.
public string ToString(string format, IFormatProvider formatProvider)
{
// 'n': print the name only.
if (format == "n")
{
return Name;
}
// 'cl': print the course list.
if (format == "cl")
{
string stringFormat = "{0,-25}{1,-30}{2,-10}\r\n";
StringBuilder str = new StringBuilder();
str.AppendLine();
str.AppendFormat(stringFormat, "Title", "Description", "ID");
str.AppendLine();
foreach (Course c in Courses)
{
str.AppendFormat(stringFormat, c.Title, c.Description, c.SectionID);
}
return str.ToString();
}
return this.ToString();
}
Public Overloads Function ToString(ByVal format As String, ByVal formatProvider As IFormatProvider) As String Implements IFormattable.ToString
' 'n': print the name only.
If format = "n" Then
Return Name
End If
' 'cl': print the course list.
If format = "cl" Then
Dim stringFormat As String = "{0,-25}{1,-30}{2,-10}" & vbCrLf
Dim str As New StringBuilder()
str.AppendLine()
str.AppendFormat(stringFormat, "Title", "Description", "ID")
str.AppendLine()
For Each c As Course In Courses
str.AppendFormat(stringFormat, c.Title, c.Description, c.SectionID)
Next c
Return str.ToString()
End If
Return Me.ToString()
End Function
ContentStringFormat can be a predefined, composite, or custom string format. For more information about string formats, see Formatting Types. If you set the ContentTemplate or ContentTemplateSelector of a TabControl, the ContentStringFormat property is ignored.
