在我们的WPF应用程序中,我们有一个显示网格的屏幕,现在列的标题是文本,我应该在文本旁边添加图像。这是XAML代码,

<Custom:DataGrid.Columns>
       <Custom:DataGridTemplateColumn Header="{Binding EmailIDHeader, Source={StaticResource LiteralDictionary}}" Width = "0.1*" CellTemplate="{StaticResource EmailIDTemplate}" SortMemberPath="EmailID"/>
 </Custom:DataGrid.Columns>

<DataTemplate x:Key="EmailIDTemplate">
        <Grid MinWidth="10" Margin="5,0,5,0">
            <TextBlock HorizontalAlignment="Left"  Text="{Binding customerItem.EmailID}" Margin="0,0,3,0"/>
        </Grid>

EMailIDHeader将加载Header的Text值,我必须在它旁边添加一个图像。我该如何实现这一目标?我尝试了here给出的解决方案。但这只是向我显示一个空标题列。

定义DataTemplate,根据需要整理文本块和图片,并使用此资源设置属性HeaderTemplate

标题的数据模板:

<DataTemplate x:Key="EmailIDHeaderTemplate">
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition/>
                <RowDefinition/>
            </Grid.RowDefinitions>
            <Image Source="SPhotoEditor-20170120_075433.jpg" Width="20" Height="20"></Image>
            <TextBlock HorizontalAlignment="Left"  Text="{Binding EmailIDHeader, Source={StaticResource LiteralDictionary}}" Margin="0,0,3,0"/>

        </Grid>
</DataTemplate>

对于细胞:

<DataTemplate x:Key="EmailIDTemplate">
    <Grid MinWidth="10" Margin="5,0,5,0">
        <TextBlock HorizontalAlignment="Left"  Text="{Binding customerItem.EmailID}" Margin="0,0,3,0"/>
    </Grid>
</DataTemplate>

你的网格:

<Custom:DataGrid.Columns>
   <Custom:DataGridTemplateColumn  HeaderTemplate="{StaticResource EmailIDHeaderTemplate}" CellTemplate="{StaticResource EmailIDTemplate}" Width = "0.1*"  SortMemberPath="EmailID"/>
</Custom:DataGrid.Columns>

假设模型是

public class Model : INotifyPropertyChanged
{
    string _value;
    public string Value{ get { return _value; } set { _value = value; RaisePropertyChanged("Value"); } }

    public event PropertyChangedEventHandler PropertyChanged;
    void RaisePropertyChanged(string propname)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propname));
    }
}

并且视图模型中有两个属性:

    string _name;
    public string Name { get { return _name; } set { _name = value; RaisePropertyChanged("Name"); } }


    string _imagePath;
    public string ImagePath { get { return _imagePath; } set { _imagePath = value; RaisePropertyChanged("ImagePath"); } }

您可以使用以下视图:

    <DataGrid DataContext="{Binding}" ItemsSource="{Binding Models}" AutoGenerateColumns="False">
        <DataGrid.Columns>
            <DataGridTemplateColumn>
                <DataGridTemplateColumn.HeaderTemplate>
                    <DataTemplate>
                        <StackPanel>
                            <TextBlock Text="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type DataGrid}}, Path=DataContext.Name}"/>
                            <Image Source="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type DataGrid}}, Path=DataContext.ImagePath}"/>
                        </StackPanel>
                    </DataTemplate>
                </DataGridTemplateColumn.HeaderTemplate>
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <TextBlock Text="{Binding Value}"/>
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
            </DataGridTemplateColumn>
        </DataGrid.Columns>
    </DataGrid>
