Listview所选项目 [英] Listview Selected Item

问题描述

全部晚上，

我遇到了一个我无法解决的问题，我已经在线检查了，但似乎找不到我想要的答案.

我有一个正在使用搜索结果框的列表视图，例如，用户输入文本，单击搜索按钮，将搜索结果作为列表视图中的项目列表返回.

我想做的是单击每个项目时都选择它，并在按下按钮时执行一些代码.因此，例如，在这种情况下，我希望用户单击列表视图中的项目，然后单击添加到配置文件"按钮，该项目将被添加到配置文件中.

我不知道如何在列表视图中获取选定的项目，我真的很努力.我基本上是在尝试使用Listview的添加列创建列表框的功能.

任何帮助将不胜感激.

Evening All,

I have come across a bit of a problem that I can''t get around, I have checked online and I can''t seem to find the answer I am looking for.

I have a listview that is being used a search results box, for example user enters text, clicks search button, returns results of search as a list of items in the list view.

What I am trying to do is select each item when it is clicked on and do some code on a button press. So for example in this case I want a user to click on an item in the listview, click add to profile button and the item will be added to a profile.

I have no idea how you get the selected item in a listview and I am really struggling with it. I am basically trying to create the functionality of a listbox with the added columns of a Listview.

Any help would be much appreciated.

推荐答案

我不确定我是否以正确的方式遇到了问题，我认为您只需要为自己设置一个ItemCommand事件处理程序即可listview，然后在按钮(或任何其他控件)中设置CommandName和CommandArgument.

I''m not sure if I''ve got your problem in the right way, I think you just need to set an ItemCommand event handler for your listview and then set the CommandName and CommandArgument in your button (or in any other control).

<asp:listview runat="server" xmlns:asp="#unknown">
        ID="TheAnimalsListView"
        OnItemCommand="TheAnimalsListView_OnItemCommand"
        DataKeyNames="TheID">
        <layouttemplate>
          [...]
        </layouttemplate>
        <itemtemplate>
              <asp:linkbutton runat="server">
                ID="SelectAnimalButton" 
                Text="Show This" 
                CommandName="ShowThis" 
                CommandArgument='<%#Eval("AnimalName")%>' />
        </asp:linkbutton></itemtemplate>
      </asp:listview>

然后，在后面的代码中

Then, in the codebehind

protected void TheAnimalsListView_OnItemCommand(object sender, ListViewCommandEventArgs e)
  {
    if (String.Equals(e.CommandName, "ShowThis"))
      {
        //Shows the image of the animal based on the AnimalName
        ShowAnimalImage(e.CommandArgument.ToString());
      }
    }
  }
