c# - WPF 从 datagridtemplatecolumn 获取 TextBox 值

Question

大家好，我正在尝试从 DataGridTemplateColum 获取 TextBox Named "txtQty" 值

这是代码，希望有人帮助我....

.XML

     <DataGrid x:Name="dataGridMain">
        <DataGrid.Columns>
            <DataGridTextColumn Header="Id" Binding="{Binding Id}" IsReadOnly="True" Visibility="Hidden"/>
            <DataGridTextColumn Header="Name" Binding="{Binding PName}" IsReadOnly="True"/>
            <DataGridTemplateColumn Header="Qty" >
                 <DataGridTemplateColumn.CellTemplate >
                       <DataTemplate >
                             <StackPanel Orientation="Horizontal">
                                  <TextBox x:Name="txtQty"/>                                                                       
                              </StackPanel>
                       </DataTemplate>
                 </DataGridTemplateColumn>
        </DataGrid.Columns>
    </DataGrid>

我尝试使用此代码

       DataRowView dt = dataGridMain.SelectedItem as DataRowView;

       String value = dt["Qty"].ToString());

经过一番努力，我发现这个解决方案很有帮助......

       int i=5; //Set this equal to desired column index.... 
          ContentPresenter myCp = dataGridMain.Columns[i].GetCellContent(dataGridMain.SelectedItem) as ContentPresenter;
        var myTemplate = myCp.ContentTemplate;
        TextBox mytxtbox = myTemplate.FindName("txtQty", myCp) as TextBox;
        MessageBox.Show(mytxtbox.Text);
