推荐答案

从数据库中返回另外一列，其中包含有关哪些行必须显示复选框并将其绑定到复选框的visible属性的信息.

希望这会有所帮助.....

Hi,

return one more column from your database which contains the information about which rows have to display the checkbox and bind it to the visible property of the checkbox.

Hope this helps.....

创建一个类并按照命名约定为其命名，并在该类中编写以下代码

Hi,

Create a class and name it as per your naming conventions and write the following code in that class

public class Converters : IValueConverter
   {
       public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
       {
           Visibility rv = Visibility.Visible;
           try
           {
               var x = bool.Parse(value.ToString());
               if (x)
               {
                   rv = Visibility.Visible;
               }
               else
               {
                   rv = Visibility.Collapsed;
               }
           }
           catch (Exception)
           {
           }
           return rv;
       }

       public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
       {
           return value;
       }

   }

现在在您的XAML中注册该类

Now in your XAML register this class

<Window x:Class="WpfTestApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525"
        xmlns:converters="clr-namespace:yournamespace">

并将此转换器添加为资源

and add this converter as a resource

<Canvas.Resources>
            <converters:Converters x:Key="boolToVis"/>

        </Canvas.Resources>

我给出了一个一般示例，按照您的要求进行操作

I am giving a general example manipulate as per your requirement

<CheckBox Canvas.Left="96" Canvas.Top="19" Content="CheckBox" Height="16" Name="checkBox1" IsChecked="True"/>
        <CheckBox Canvas.Left="96" Canvas.Top="54" Content="CheckBox" Height="16" Name="checkBox2" Visibility="{Binding ElementName=checkBox1,Path=IsChecked,Converter={StaticResource boolToVis}}"/>

例如:

< datagridcheckboxcolumn binding ="{已检查绑定}" cellstyle ="{StaticResource SingleClick}"可见性="{Binding Path =您的数据库列名称，Converter = {StaticResource boolToVis}}">



希望这会有所帮助.

如果需要更多详细信息，请告诉我

问候，
斯里曼(Sriman)

Eg:

<datagridcheckboxcolumn binding="{Binding checked}" cellstyle="{StaticResource SingleClick}" visibility="{Binding Path=your database column name,Converter={StaticResource boolToVis}}">



Hope this helps.

Do let me know if you need any more details
