GridView.RowCommand 事件获取主键值的方法

1. RowCommond 事件

.aspx

在GridView添加一模板列，加上CommandArgument 并绑定如下

1 <asp:GridView ID="gvAdminList" runat="server">            
2 <asp:TemplateField>
3   <ItemTemplate>
4      <asp:LinkButton ID="lbtnLook" runat="server" CommandName="GetAdminInfo" CommandArgument='<%# Eval("AdminID") %>'>查看</asp:LinkButton>
5      </ItemTemplate>
6   </asp:TemplateField>
7 </asp:GridView>

.aspx.cs(C#)
读取CommandArgument

当单击 GridView 控件中的按钮时发生。

1protectedvoid gvAdminList_RowCommand(object sender, GridViewCommandEventArgs e)
2{
3  if (e.CommandName =="GetAdminInfo")
4    {
5      string AdminID = e.CommandArgument.ToString();
6     }
7}

命名空间： System.Web.UI.WebControls
程序集： System.Web（在 System.Web.dll 中）

语法

Public Event RowCommand As GridViewCommandEventHandler

Dim instance As GridView  Dim handler As GridViewCommandEventHandler    AddHandler instance.RowCommand, handler

public event GridViewCommandEventHandler RowCommand

public:   event GridViewCommandEventHandler^ RowCommand {      void add (GridViewCommandEventHandler^ value);      void remove (GridViewCommandEventHandler^ value);  }

/** @event */  public void add_RowCommand (GridViewCommandEventHandler value)  /** @event */  public void remove_RowCommand (GridViewCommandEventHandler value)

JScript 不支持事件。
