推荐答案

下面说明了如何在网格中访问linkbutton，并在服务器端的linkbutton中添加了一些额外的数据.

试试:
以下将ItemName绑定到LinkButton的CommandArgument.

Following illustrates access of linkbutton in grid with some extra data in linkbutton on server side.

Try:
Following binds the ItemName to the CommandArgument of the LinkButton.

<asp:LinkButton ID="LinkButton1" runat="server" Text="Add to cart"

   OnClick="LinkButton1_Click" CommandArgument='<%# Eval("ItemName") %>' />

然后，您可以在后面的代码中像这样检索它:

You can then retrieve it like this in the code behind:

protected void LinkButton1_Click(object sender, EventArgs e)
{
  LinkButton myButton = sender as LinkButton;
  if (myButton != null)
  {
     string title = myButton.CommandArgument;
     // use this title now to set as a text for your label.
     // Use below for rowIndex
     // CommandArgument='<%# Container.DataItemIndex %>'
   }
}

发送方持有对触发事件处理程序的LinkButton的引用.
您可以将对象转换为LinkButton，然后检索其CommandArgument并将其转换为字符串.

The sender holds a reference to the LinkButton that triggered the event handler.
You can cast the object into a LinkButton and then retrieve its CommandArgument and cast that into string.
