最好的方法是什么(选择行，单击按钮将其删除) [英] What's the best way for (select row, delete it on button click)

问题描述

我找不到解决问题的办法. 这是我正在从事的MVC项目.

I could not find any solution for my problem. This is a MVC project I am working on.

在GridView中，我该怎么做:Click on row and then click on button to delete this selected or clicked row.

In the GridView how can I do this: Click on row and then click on button to delete this selected or clicked row.

不需要任何带有自动选择按钮的解决方案.

Don't need any solution with automatic Select button.

所以

1. 鼠标单击该行

1. Mouse click on the row

获取其ID或任何值

重定向到我的函数+ ID的按钮.

Button that redirect to my function + Id.

gridview是不可能的吗?如果使用Table会更好吗?

Is it impossible with gridview? would it be better if I use Table?

这是我尝试过的:

//To get the id 
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
    {
        e.Row.RowIndex.ToString();
        string id = DataBinder.Eval(e.Row.DataItem, "Id").ToString();
       e.Row.Attributes.Add("rowid", id);
    }

}

我的javascript按钮

My javascript an button

 <a href='<%=ResolveUrl("~/Producter/Delete?id=" ) %>' ID="HyperLink1">Delete</a>

<script  type ="text/javascript" language="javascript">
    //every time a row is clicked this script will perform the following actions:
    $("tr").click(function () {
        var clicked = $(this);
        //get the row id from the currently cliked row
        var rowid = clicked.attr("rowid");
        //get the value of href attribute from the link with id 'HyperLink1'
        var link = $("#HyperLink1").attr("href");
        //remove any previously appended values
        var linkTokens = link.split("=");
        linkTokens[1] = "";
        link = linkTokens.join("=");
        //append the current row id to the link
        link = link + rowid;
        //set the href attribute of your link to the new value
        $("#HyperLink1").attr("href", link);
    });
</script>

Got id =一直未定义.

Got id = undefined all the time.

推荐答案

如果您使用的是MVC，我认为您对GridView的使用都错了，正如我从后面的代码中看到的那样. 这是一个与MVC不兼容的服务器控件，因为它依赖于PostBack和ViewState. 您可以以面向MVC的方式"轻松完成此操作:

If you're using MVC, I think you got the usage of GridView all wrong as I can see from your code behind. This is a server control which isn't compatible with MVC since it depends on PostBack and ViewState. You can do it quite easily in "MVC oriented fashion":

比方说，您想从称为产品"的操作方法中显示产品"列表.

Let's say you want to show list of Products from an action method called 'Products'.

1. 右键单击该控制器动作并添加新的视图.
2. 弹出一个模式对话框.
3. 命名为产品"的视图.
4. 从列表中选择它将强烈绑定的类型，因此 产品"类.
5. 选择视图类型为列表".
6. 选择布局页面(如ASP.NET中的MasterPage).
7. 就是这样.

1. Right-Click that controller action and add new View.
2. A modal dialog pops up.
3. Name that view 'Products'.
4. Choose from the list the type it will strongly bound to, hence 'Product' class.
5. Choose the type of view as 'List'.
6. Choose the layout page (Like MasterPage in ASP.NET).
7. that's it.

现在，在控制器操作中，您将调用该View并将其传递给Products集合，如下所示:

Now, in the controller action, you shold call that View and pass it a collection of Products, something like that:

public ActionResult Products()
{
  List<Products> products = SomeMethodToGetProducts();

  return View(products);
}

简单！

您现在要做的就是在生成的视图中填充编辑"，删除"等操作.

All you have to do now is populate the actions in the generated view like 'Edit', 'Delete' and so on.
