如何使用Silverlight MVVM在Datagridview中为datagrid中的选定项目设置日期 [英] How to set date in datagridview for selected items in datagrid using silverlight mvvm

问题描述

你好，

我是Silverlight的新手.正在开发使用WCF服务与集合绑定的datagridview.我的问题在这里...我可以将表填充到datagrid.我将选择的项目添加到列表框中.我试图在列表框中选择项目并需要为此输入一些日期，然后再次在datagrid中进行更新.

这是示例代码:

学生
startDate
结束日期

保罗
2011/08/01


山姆
2011年8月2日


院长
2011/08/03


StartDate


列表框

保罗

萨姆


现在，如果我需要选择列表框项目，并在gridview..update中的gridview中分配开始日期
这是我的代码:

<telerik:RadGridView Name="StudentInfoGrid" Grid.Row="2" Grid.ColumnSpan="2"

                                                              ItemsSource="{Binding studentCollection}"

                                                                  SelectedItem="{Binding SelectedStudentInfo,Mode=TwoWay}"

                                                               IsReadOnly="True" SelectionChanged="StudentInfoGrid_SelectionChanged"

                                                              SelectionMode="Single">

                     <telerik:GridViewDataControl.Columns>

                         <telerik:GridViewDataColumn Header="studnet" DataMemberBinding="{Binding studentname}" TextAlignment="Left" Width="*">

                                </telerik:GridViewDataColumn>

                         <telerik:GridViewDataColumn x:Name="StartDate_GridView"   Header="Start Date" DataMemberBinding="{Binding egStartDate,Converter={StaticResource dateConverter}}" MaxWidth="100" />

                         <telerik:GridViewDataColumn Header="End Date" DataMemberBinding="{Binding   egEndDate,Converter={StaticResource dateConverter}}" MaxWidth="100" />



                    </telerik:GridViewDataControl.Columns>



                 </telerik:RadGridView>





                     <telerik:RadDatePicker x:Name="SetStartDate" Grid.Row="0" Grid.Column="1" SelectedValue="{Binding Path=listBoxSelectedItems.SelectedItems.egStartDate,Mode=TwoWay,Converter={StaticResource dateConverter}}" Width="150" HorizontalAlignment="Left"  DisplayFormat="Long" Height="25" />

private void EmployeeGroupbtnClick(object sender, RoutedEventArgs e)

     {

        if (listBoxSelectedItems.SelectedIndex != -1)

          {

             //MessageBox.Show(SetStartDate.SelectedValue.ToString());

             DateTime datePicker1 = SetStartDate.SelectedDate.Value;

              //DateTime datepicker2 = SetEndDate.SelectedDate.Value;



             foreach(var a in listBoxSelectedItems.SelectedItems)

             {

                 Setdate(datePicker1);



                ViewModel.SaveEmployeeGroupAssoc(a as EmployeeGroupAssocData);

             }

           }

      }

     public void Setdate(DateTime datePicker1)

     {



         this.ViewModel.EditedEmployeeGroupAssoc.OriginalEmployeeGroupAssoc.egStartDate = datePicker1;



     }

请帮我解决这个问题.

预先谢谢您

推荐答案

你好
我相信您可以使用"GridViewTemplateColumn"代替"GridViewDataColumn".
这样，您可以使用文本框或类似DateTimePicker的控件输入值来为单元格创建模板.

Hello
I believe that you can use an "GridViewTemplateColumn" instead of "GridViewDataColumn".
That way, you can create a template for the cell, using a TextBox or a DateTimePicker-like control to input values.
