从列表框wpf中获取选中的复选框标记值 [英] Get selected checkbox tag value from Listbox wpf

问题描述

你好开发者，



我正在使用WPF应用程序，我有一个列表框，语法如下。

 <   Window.Resources  >  
 <   DataTemplate     x：密钥  =  ListBoxItemTemplate   >  
 <！ -    < WrapPanel>    -  - >   
 <   CheckBox     N. ame   =  CheckBoxZone   内容  =  {Binding SoilStatus}   保证金  =  3,10   标记  =  {Binding ID}    /  >  
 <！ -    < / WrapPanel>    - >   
 <   / DataTemplate  >  
 <   / Window.Resources  >  

 <   ListBox    网格.Row   =  0    Grid.Column   =  1   保证金  =  3 10   名称  =  lstSoilStatus      ItemTemplate   =  {DynamicResource ListBoxItemTemplate}    ScrollViewer.Horizo​​ntalScrollBarVisibility   = 已禁用 >  
 <   ListBox.ItemsPanel  >  
 <  < span class =code-leadattribute> ItemsPanelTemplate  >  
 <   WrapPanel    方向  =  Horizo​​n tal >  <   / WrapPanel  >  
 <   / ItemsPanelTemplate  >  
 <   /ListBox.ItemsPanel  >  
 <   / ListBox  >  

我从代码绑定此值，以下是要绑定的代码：

 string query =SELECT ID，SoilStatus FROM SoilStatus ORDER BY SoilStatus; 
 DBOperation obj = new DBOperation（）; 
 DataTable dt = obj.GetData（query）; 
 lstSoilStatus.ItemsSource = dt.AsDataView（）; 

我的代码按预期工作。

现在我选择了多个复选框作为我的要求。

我想在c＃代码中获取所选复选框的标签值。

如何实现这一目标？

有什么想法？

解决方案

你可以试试使用包含对象的类（绑定列表的对象）和检查/取消选中的布尔值。然后，您可以遍历该集合并查找已检查的条目。哦，记得将CheckBox的IsChecked属性绑定到你的值。



希望这会有所帮助。

Hello Developer,

I am working with WPF application where I have a Listbox with following syntax.

<Window.Resources>
        <DataTemplate x:Key="ListBoxItemTemplate" >
            <!--<WrapPanel>-->
                <CheckBox Name="CheckBoxZone" Content="{Binding SoilStatus}" Margin="3, 10" Tag="{Binding ID}" />
            <!--</WrapPanel>-->
        </DataTemplate>
    </Window.Resources>

<ListBox Grid.Row="0" Grid.Column="1" Margin="3 10" Name="lstSoilStatus"  ItemTemplate="{DynamicResource ListBoxItemTemplate}" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
                            <ListBox.ItemsPanel>
                                <ItemsPanelTemplate>
                                    <WrapPanel Orientation="Horizontal"></WrapPanel>
                                </ItemsPanelTemplate>
                            </ListBox.ItemsPanel>
                        </ListBox>

I am binding this value from code, following is the code to bind:

string query = "SELECT ID, SoilStatus FROM SoilStatus ORDER BY SoilStatus";
                DBOperation obj = new DBOperation();
                DataTable dt = obj.GetData(query);
                lstSoilStatus.ItemsSource = dt.AsDataView();

My code is working as expected.
Now I am selecting multiple checkbox as my requirement.
And I want to get the tag value of that selected checkbox in c# code.
How can I achieve this?
Any idea?

解决方案

Hi,

You may try to use a class that contains your object (the one you bind the list from) and a boolean value which is checked/unchecked. Then you can iterate through that collection and find the checked entries. Oh, remember to bind the IsChecked property of the CheckBox to your value.

Hope this helps.

I put the answer here in order to tell other that it has a solution. :-)
