So Ive got an ToolBar and wanted to Bold my Text, with an RichTextBox its working but not with an normal regular TextBox. Could someone tell me why only RichTextBox is working and not the normal one? And how could I get the normal TextBox to work because the RichTextBox is impractical.

My Code looks like that:

<DockPanel>
        <ToolBarTray DockPanel.Dock="Top">
            <ToolBar>
                <Button Command="Cut" ToolTip="Cut selection to Windows Clipboard.">
                </Button>
                <Button Command="Copy" ToolTip="Copy selection to Windows Clipboard.">
                </Button>
                <Button Content="Hallo" Command="ToggleBold" ToolTip="Paste from Windows Clipboard.">
                   
                </Button>
                <Separator />
                <Label>Font size:</Label>
                <ComboBox>
                    <ComboBoxItem>10</ComboBoxItem>
                    <ComboBoxItem IsSelected="True">12</ComboBoxItem>
                    <ComboBoxItem>14</ComboBoxItem>
                    <ComboBoxItem>16</ComboBoxItem>
                </ComboBox>
            </ToolBar>
        </ToolBarTray>
        <TextBox AcceptsReturn="True" />
    </DockPanel>

CodePudding user response：

The TextBox does not support formatting related commands like ToggleBold (Ctrl B).

See the documentation: TextBox or RichTextBox?
