问题描述

您好，我想要抓住事件点击datagridColumnHeader中的CheckBox。

Hello, I want catch event Click of CheckBox in datagridColumnHeader.

datagirdTemplateColumn.HeaderStyle = (Style)XamlReader.Load(CreateStyleColumnHeader(documentUserSummary.UserIds[i]));
 private string CreateStyleColumnHeader(int userId)
        {
            StringBuilder sHeader = new StringBuilder();
            sHeader.Append("<Style xmlns=\"http://splashurl.com/o2ho2ey TargetType=\"datalocalprimitives:DataGridColumnHeader\">");
            sHeader.Append("<Setter Property=\"Template\">");
            sHeader.Append("<Setter.Value>");
            sHeader.Append("<ControlTemplate TargetType=\"datalocalprimitives:DataGridColumnHeader\">");
            sHeader.Append("<Grid>");
            sHeader.Append(" <CheckBox Grid.Row=\"1\" Margin=\"7,5,0,0\" HorizontalAlignment=\"Center\" x:Name=\"CheckAll\" Click=\"CheckAll_Click\" ");
            sHeader.AppendFormat("Tag=\"{0}\" ", userId);
            sHeader.Append(" />");
            sHeader.Append("</Grid>"); 
            sHeader.Append("</ControlTemplate>");
            sHeader.Append(" </Setter.Value>"); 
            sHeader.Append(" </Setter>");
            sHeader.Append(" </Style>");
            return sHeader.ToString();
        }

你能帮助我吗？

谢谢

您好，

根据您的标记，我在使用样式的datagridColumnHeader中的复选框内看到了您。对于复选框的复选框事件，它与DataGrid之外的场景没有什么不同。以下是供您参考的代码段：

According to your markup, I saw you inside your checkbox in datagridColumnHeader using style. for checkbox's checkbox event, it's not different from the scenario that it outside of the DataGrid. Below is a code snippet for your reference:

<data:DataGrid x:Name=″myDataGrid″ AutoGenerateColumns=″False″>
        <data:DataGrid.Columns>
             <data:DataGridTemplateColumn>
                   <data:DataGridTemplateColumn.HeaderStyle>
                        <Style TargetType=″dataprimitives:DataGridColumnHeader″>
                             <Setter Property="Template">
                                  <Setter.Value>
                                       <ControlTemplate>
                                            <Grid>
                                                 <Grid.ColumnDefinitions>
                                                      <ColumnDefinition> </ColumnDefinition>
                                                 </Grid.ColumnDefinitions>
                                                <CheckBox x:Name="chkAll" Click="chkAll_Click" Grid.Column="0"/>
                                           </Grid>
                                      </ControlTemplate>
                                 </Setter.Value>
                            </Setter>
                       </Style>
                  </data:DataGridTemplateColumn.HeaderStyle> 
                  <data:DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                              <CheckBox x:Name="chkBoxID" Click="chkBoxID_Click" Tag="{Binding Path=ID}" />
                        </DataTemplate>
                 </data:DataGridTemplateColumn.CellTemplate>
          </data:DataGridTemplateColumn>
 
   </data:DataGrid.Columns>
</data:DataGrid>


code behind:
private void chkAll_Click(object sender, RoutedEventArgs e)
{
         CheckBox chk = sender as CheckBox;
         bool check = chk.IsChecked.Value;
         foreach (CheckBox chkbox in checkboxes)
              chkbox.IsChecked = check;
}
