如何在窗口加载时获取WPF菜单项名称？ [英] How to get WPF Menu items names when window loaded?

问题描述

我是WPF的新手，我有这个：

I''m new in WPF and I have this :

<Grid>
 <Menu VerticalAlignment="Top" Margin="8,13,20,0" Foreground="#FF4B5D51" Height="29" Name="baseMenu"

                      HorizontalAlignment="Stretch" removed="{x:Null}" BorderBrush="#FF4B5D51" 

                      HorizontalContentAlignment="Right" FontFamily="Tahoma" FontSize="14">
<MenuItem Visibility="Collapsed" Header="Management" x:Name="mnuManagement" Foreground="#FFE3A036" 

                              FontSize="15">
                <!--Employees-->
                <MenuItem Visibility="Collapsed" Header="Employees" x:Name="EmpsMenuItem" removed="{x:Null}"

                              FontSize="15" Foreground="#FFE3A036"  BorderBrush="{x:Null}">
                </MenuItem>
                <MenuItem Visibility="Collapsed" Header="Categories" x:Name="catMenuItem" removed="{x:Null}"

                              FontSize="15" Foreground="#FFE3A036"  BorderBrush="{x:Null}">
                </MenuItem>
                <MenuItem Visibility="Collapsed" Header="Products" x:Name="prodMenuItem" removed="{x:Null}"

                              FontSize="15" Foreground="#FFE3A036"  BorderBrush="{x:Null}">
                </MenuItem>
            </MenuItem>
<!--الموردين-->
            <MenuItem Visibility="Collapsed" Header="Suppliers" x:Name="mnuSuppliers" Foreground="#FFE3A036" 

                              FontSize="15">
                <!--الموردين-->
                <MenuItem Visibility="Collapsed" Header="Branches" x:Name="BranchesMenuItem" removed="{x:Null}"

                              FontSize="15" Foreground="#FFE3A036"  BorderBrush="{x:Null}">
                </MenuItem>
            </MenuItem>
        </Menu>
</Grid>

我想要做的是获取每个菜单项名称并将它们放在一个数组中，我想这样做是为了根据菜单项名称给予用户权限as：如果ai有用户号码。 1&我会给他这个许可：

What I want to do is get every menu item name and put them in an array, I want to do that to give the user permission according to menu item name such as: If a i have user no. 1 & I will give him this permission:

Management.isenable = true; 
EmpsMenuItem.isenable = false; 
mnuSuppliers.isenable = true;

所以我想循环到这个数组给他权限，但我不知道如何做到这一点。



我该怎么做？

So I want to looping into this array to give him permissions ,but I don''t have any idea about how to do that.

How would I do this?

推荐答案

你可以采取各种方法来实现这一目标。



可以在form.controls集合上进行foreach循环，在那里搜索MenuItem类型的控件，然后从中收集name属性并放入在数组中。然后，当你想要检索一个控件时，你可以使用这样的扩展方法：

来检索控件，然后设置相应的启用/禁用。



另一种方法可能是使用命令来启用/禁用菜单：< br $> b $ b

希望这些想法可以帮到你。

There are various approaches you could take to achieve this.

one could be to do a foreach loop on the form.controls collection where you are searching for a control of type MenuItem, then collect the name property from it and put that in an array. Then when you want to retrieve a control you could use an extension method such as this:

http://stackoverflow.com/questions/8737091/get-control-by-name-including-children[^]

to retrieve the control, and in turn set the appropriate enable/disable.

Another approach could be to use commands to enable/disable menus:

Hope these ideas help you.

我ave实际上没有对此进行过测试，但它应该适用于你的简单案例：

I have not actually tested this, but it should work for your simple case:

var names = baseMenu.Items.Cast<menuitem>().Select(j => j.Name);</menuitem>

我必须做的是根据所选记录动态更改上下文菜单。我使用 ContextMenuOpening 事件，然后使用ViewModel中的方法来确定 MenuItem 是否应该可见

What I have had to do is dynamically change a context menu depending on the selected record. I used the ContextMenuOpening event and then used a method in the ViewModel to determine if MenuItem should be visible
