如何将TabControl标题链接到调用MenuItem标题 [英] How do I Link A TabControl Header to calling MenuItem Header

问题描述

大家好，



我已经决定试用WPF而且我一直坚持命名tabcontrol标题。使用Josh的帖子，我的愿望是每次用户点击菜单时都会创建一个Tab，并且标签的标题将被设置为调用menuitem标题。我怎样才能以最简单的方式实现这一目标。请告知我应该使用哪个功能。 Thanx提前！

菜单xaml

 <  菜单   名称  =  mnuMain    DockPanel.Dock   = 顶部    Horizo​​ntalAlignment   = 拉伸     宽度  = 自动    MenuItem.Click     =  menuClick >  
 <   MenuItem    标题  =  _File >  
 <   MenuItem    命令  =  {绑定NewWorkspaceCommand}   标题  =  _新标签    InputGestureText   =  Ctrl + N    /  >  
 <   MenuItem    命令  =  {Binding CloseWorkspaceCommand}   标题  =  _关闭标签    InputGestureText   =  Ctrl + F4    /  >  
 <  我nuItem    命令  =  {Binding ExitCommand}   标题  =  E_xit    InputGestureText   =  Ctrl + X    /  >  
 <   / MenuItem  >  

标签控制如下

 <   TabControl.Background    >  
 <   ImageBrush  < span class =code-attribute>   ImageSource   =  / Resources / images / background.png   拉伸  =  UniformToFill    /  >  
 <   / TabControl.Background  >  
 
 <   TabControl.ItemTemplate  >  
 <   DataTemplate  >  
 <   WrapPanel  >  
 <   TextBlock    文字  =  {Binding Header}    /  >  
 <  按钮   命令  =  {Binding CloseCommand}   内容  =  X   保证金  =  4,0,0,0    FontFamily   =  Courier New    宽度  = < span class =code-keyword> 17   高度  =  17    VerticalContentAlignment   = 中心    /  >

 < span class =code-keyword><   / DataTemplate  >

Hi Guys,

I have decided to try out WPF and I am stuck on naming the tabcontrol header. Using Josh's post my wish is to a have Tab created everytime a user clicks a menu and the tab's header will be set to the calling menuitem header. How can I accomplish this in the simplest way. Please advice on which feature I should use. Thanx in advance!

menu xaml

<Menu Name="mnuMain" DockPanel.Dock="Top" HorizontalAlignment="Stretch"  Width=" Auto" MenuItem.Click ="menuClick">
              <MenuItem Header="_File">
                  <MenuItem Command="{Binding NewWorkspaceCommand}" Header="_New Tab" InputGestureText="Ctrl + N" />
                  <MenuItem Command="{Binding CloseWorkspaceCommand}" Header="_Close Tab" InputGestureText="Ctrl + F4" />
                  <MenuItem Command="{Binding ExitCommand}" Header="E_xit" InputGestureText="Ctrl + X" />
              </MenuItem>

tab control is as follows

<TabControl.Background >
                <ImageBrush ImageSource="/Resources/images/background.png" Stretch="UniformToFill" />
            </TabControl.Background>

            <TabControl.ItemTemplate>
                <DataTemplate>
                    <WrapPanel>
                        <TextBlock Text="{Binding Header}" />
                        <Button Command="{Binding CloseCommand}" Content="X" Margin="4,0,0,0" FontFamily="Courier New" Width="17" Height="17" VerticalContentAlignment="Center" />
