WPF C＃DataGrid编辑单元

Question

我在编辑DataGrid中的单元格时遇到问题。

当我在一个单元格双击，将引发一个例外 - InvalidOperationException 'EditItem' is not allowed for this view

我正在寻找在数据网格编辑细胞的最简单方法。

XAML --------------------------------------------- ---------------------------------- XAML

<DataGrid x:Name="ZdarzeniaDataGrid" AutoGenerateColumns="False" CanUserAddRows="True" HorizontalAlignment="Left" Margin="71,398,0,0" VerticalAlignment="Top" Height="279" Width="1119"> 
      <DataGrid.Columns> 
       <DataGridTextColumn Binding="{Binding IdZdarzenia}" Header="Id Zdarzenia" Width="100"/> 
       <DataGridTextColumn Binding="{Binding Gospodarze}" Header="Gospodarze" Width="100"/> 
       <DataGridTextColumn Binding="{Binding Goście}" Header="Goście" Width="100"/> 
       <DataGridTextColumn Binding="{Binding Kurs1}" Header="Kurs 1" Width="100"/> 
       <DataGridTextColumn Binding="{Binding Kurs0}" Header="Kurs 0" Width="100"/> 
       <DataGridTextColumn Binding="{Binding Kurs2}" Header="Kurs 2" Width="100"/> 
       <DataGridTextColumn Binding="{Binding Kurs10}" Header="Kurs 10" Width="100"/> 
       <DataGridTextColumn Binding="{Binding Kurs20}" Header="Kurs 20" Width="100"/> 
       <DataGridTextColumn Binding="{Binding Kurs12}" Header="Kurs 12" Width="100"/> 
       <DataGridTextColumn Binding="{Binding DataZdarzenia}" Header="Data Zdarzenia" Width="100"/> 
      </DataGrid.Columns> 
     </DataGrid> 

C＃------- -------------------------------------------------- --------------------- C＃

ZdarzeniaDataGrid.Items.Add(
    new { IdZdarzenia = napis.ItemArray.GetValue(0).ToString(), 
      Gospodarze = napis2.ItemArray.GetValue(0).ToString(), 
      Goście = napis3.ItemArray.GetValue(0).ToString(), 
      Kurs1 = napis.ItemArray.GetValue(3).ToString(), 
      Kurs0 = napis.ItemArray.GetValue(4).ToString(), 
      Kurs2 = napis.ItemArray.GetValue(5).ToString(), 
      Kurs10 = napis.ItemArray.GetValue(6).ToString(), 
      Kurs20 = napis.ItemArray.GetValue(7).ToString(), 
      Kurs12 = napis.ItemArray.GetValue(8).ToString(), 
      DataZdarzenia = napis.ItemArray.GetValue(9).ToString() 
    });

创建类与定义的所有属性和设置/绑定Dataset的ItemsSource的Data类列表。

public class Data 
    { 
     public string IdZdarzenia {get;set;} 
     public string Gospodarze {get;set;} 
     public string Goście {get;set;} 
     public string Kurs1 {get;set;} 
     public string Kurs0 {get;set;} 
     public string Kurs2 {get;set;} 
     public string Kurs10 {get;set;} 
     public string Kurs20 {get;set;} 
     public string Kurs12 {get;set;} 
     public string DataZdarzenia { get; set; } 
    } 

设置的ItemSource

List<Data> dataSource = new List<Data>(); 
    dataSource.Add(new Data() 
    { 
         IdZdarzenia = "a", 
         Gospodarze = "d", 
         Goście = "f", 
         Kurs1 = "g", 
         Kurs0 = "r", 
         Kurs2 = "gs", 
         Kurs10 = "sd", 
         Kurs20 = "sds", 
         Kurs12 = "sdss", 
         DataZdarzenia = "eeee"}); 
    ZdarzeniaDataGrid.ItemsSource = dataSource; 

这应该解决您的问题。

谢谢
