HeaderString Property

Gets or sets a string value that represents this TabItem's corresponding MenuItem's Header in the dropdown menu. This is a dependency property.

Syntax
C#
Copy
 public String HeaderString { get; set; }

Property Value

The default value is null.

Remarks

EO.Wpf TabControl can display a drop down menu that contains a menu item for each tab item. User can select a menu item from this drop down menu to select the corresponding tab item. By default, if no value is given to HeaderString, the TabControl scans the header content/template for any TextBlock visual element, and build a string value based on the TextBlock's Text property, then use this string for the menu item text. The shortcoming of this approach is that if there is no TextBlock element in the header content/template, then the result value will be an empty string.

Assigning a value to the HeaderString property ensures that this TabItem is properly represented in the dropdown menu.

Example

The following example demonstrates how this property is used:

XAML
Copy
<Window x:Class="Test.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:eo="http://schemas.essentialobjects.com/wpf/"
        Title="MainWindow" 
        Height="350" 
        Width="525">
    <Grid>
        <eo:TabControl x:Name="TabControl" DropDownMenuMode="Always">
            <eo:TabItem HeaderString="Red">
                <eo:TabItem.Header>
                    <Rectangle Fill="Red" Margin="2" Width="50" Height="20" />
                </eo:TabItem.Header>
            </eo:TabItem>
            <eo:TabItem HeaderString="Green">
                <eo:TabItem.Header>
                    <Rectangle Fill="Green" Margin="2" Width="50" Height="20" />
                </eo:TabItem.Header>
            </eo:TabItem>
            <eo:TabItem HeaderString="Blue">
                <eo:TabItem.Header>
                    <Rectangle Fill="Blue" Margin="2" Width="50" Height="20" />
                </eo:TabItem.Header>
            </eo:TabItem>
        </eo:TabControl>
    </Grid>
</Window>
