绑定到ComboBox SelectedValue和ItemsSource

问题描述

我有一个工作人员表和一个工作人员表

i have a staff table and a staffmember table 

      Tbl_Staff :

     Tbl_Staff:

        ID

        Id

       员工

        Staff

      Tbl_StaffMembers :

     Tbl_StaffMembers:

        ID

        Id

       名字

        FirstName

       员工

        Staff

 

我正在尝试将  ComboBox ItemsSource  =  Tbl_Staff

I am trying to bind the ComboBox ItemsSource = Tbl_Staff

并且  SelectedValue =行类型为  Tbl_StaffMembers.staff ...

and  SelectedValue =to a row type of Tbl_StaffMembers.staff...

 

这是我的代码，我设法填充了ItemsSource，但是在将selectedvalue绑定到职员行时遇到了问题

this is my code, i managed to fill the ItemsSource  but im having problems with binding the selectedvalue to the staffmember row

 

             //将数据绑定到组合框.

             //Binding the data to the combobox.

            CmbBStaff.DataContext = dTblStaff;//ds.Tables ["Category"].DefaultView;

            CmbBStaff.DataContext = dTblStaff;// ds.Tables["Category"].DefaultView;

            CmbBStaff.DisplayMemberPath = dTblStaff.Columns ["Staff"].ToString();

            CmbBStaff.DisplayMemberPath = dTblStaff.Columns["Staff"].ToString();

            CmbBStaff.SelectedValuePath = dTblStaff.Columns ["Id"].ToString();

            CmbBStaff.SelectedValuePath = dTblStaff.Columns["Id"].ToString();

 

    xml:

   xml:

< ComboBox Grid.Column ="1" Grid.Row ＝"3".高度＝"23". Horizo​​ntalAlignment =左"保证金＝"6".名称="CmbBStaff". VerticalAlignment =顶部"宽度＝"170". ItemsSource ="{Binding}"/>

 <ComboBox Grid.Column="1" Grid.Row="3" Height="23" HorizontalAlignment="Left" Margin="6" Name="CmbBStaff" VerticalAlignment="Top" Width="170" ItemsSource="{Binding}"/>
