Property Value

Type: System.Object

The content of the currently selected TabItem. The default is null.

This property is updated to reference the Content of the active TabItem when the tab selection changes.

The ControlTemplate of the TabControl uses the ContentPresenter.ContentSource property to bind the ContentPresenter.Content property to this property. If you create a new ControlTemplate for the TabControl, be sure to the bind the ContentPresenter.Content property to this property by setting the ContentPresenter.ContentSource property to "SelectedContent" or by using TemplateBinding Markup Extension.

<object property="{TemplateBinding SelectedContent}"/>

Identifier field

SelectedContentProperty

Metadata properties set to true

None

The following example uses the SelectedContent property to get the Person in the currently selected TabItem.


If TypeOf tabCtrl1.SelectedContent Is Person Then

    Dim selectedPerson As Person = tabCtrl1.SelectedContent

    Dim personInfo As StringBuilder = New StringBuilder()

    personInfo.Append(selectedPerson.FirstName)
    personInfo.Append(" ")
    personInfo.Append(selectedPerson.LastName)
    personInfo.Append(", ")
    personInfo.Append(selectedPerson.HomeTown)
    MessageBox.Show(personInfo.ToString())
End If

The following example creates a ControlTemplate for the TabControl. Setting the ContentSource property to "SelectedContent" creates aliases to the SelectedContent, SelectedContentTemplate, and SelectedContentTemplateSelector properties.

            <ContentPresenter x:Name="PART_SelectedContentHost"
                              Margin="4"
                              ContentSource="SelectedContent" />
          </Border>
        </Grid>
