Question

我想知道如果一列的值乘以另外两列该怎么办

这是我的数据网格图像

<telerik:RadGridView x:Name="DataGridBardashtVajh" SelectionMode="Single"  ClipboardCopyMode="All" ShowGroupPanel="false" CanUserReorderColumns="true"   AutoGenerateColumns="False"  HorizontalAlignment="Left" VerticalAlignment="Top" Height="251" Width="980" Margin="0,609,-1,0" IsReadOnly="True" FlowDirection="RightToLeft" MouseDoubleClick="DatagridEstelam_OnMouseDoubleClick">
            <telerik:RadGridView.Resources>
                <Style TargetType="telerik:GridViewCell" x:Key="textFont">

            <telerik:RadGridView.Columns>
                <telerik:GridViewSelectColumn/>

            </telerik:RadGridView.Columns>

您可以使用 Telerik计算列功能来实现此目的。

在您的xml中；

 <Grid.Resources> 
        <local:CalculatedValueConverter x:Key="calculatedValueConverter"/> 
    </Grid.Resources> 

 <telerik:GridViewDataColumn       
      Header="calculated value"  
      DataMemberBinding="{Binding Path=., Converter={StaticResource 
        calculatedValueConverter}}"> 
</telerik:GridViewDataColumn>

，您应该创建一个转换器来计算如下所示的值，并在Convert方法中实现所需的计算；

 internal class CalculatedValueConverter : IValueConverter 
{ 
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture) 
    { 
        var obj = value as YourObject; 
        if (obj  == null) 
        { 
            throw new ArgumentException("value must be a YourObject", "value"); 
        } 

        return obj.col1 * obj.col2; 
    } 

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) 
    { 
        throw new NotImplementedException(); 
    } 
}
