如何在pageindexchanging事件中从gridview获取linkbutton id 

解决方案

在网格视图标记中定义按钮，并为按钮分配一个CommandName值，如下所示

 <   pre  >  <   asp：GridView     ID   =  GridView1    AutoGenerateColumns   =  False    runat   =  server < span class =code-attribute>     
   
                   OnRowCommand   =  GridView1_RowCommand >  
 <  列 >  
 <   asp：TemplateField     HeaderText   = 添加记录 >  
 <   ItemTemplate  >  
 <   asp：按钮    ID   =  btnAddRecord      
   
                                                           CommandArgument   =  <％＃（（GridViewRow）Container）.RowIndex ％>    
   
                                                           CommandName   =  AddRecord    runat   =  server    Text   = 添加    /  >  
 <  < span class =code-leadattribute> / ItemTemplate  >  
 <   / asp：TemplateField  &g t;  
 <   / Columns  >  
 <   / asp：GridView  >  

现在在你的代码隐藏中，你可以处理OnRowCommand事件和AddRecord命令，如下所示：

  protected   void  GridView1_RowCommand（ object  sender，GridViewCommandEventArgs e）
 {
  if （e.CommandName ==   AddRecord ）
 {
  //  获取作为命令参数传递的行的索引 
  int  index = Convert.ToInt 32（e.CommandArgument.ToString（））; 
 
  //  这里的逻辑 
} 
 }

解决方案

Define the button in your grid view markup and assign a CommandName value to the button, like this

<pre><asp:GridView ID="GridView1" AutoGenerateColumns="False" runat="server"  

        OnRowCommand="GridView1_RowCommand">
    <Columns>
        <asp:TemplateField HeaderText="Add Record">
            <ItemTemplate>
                <asp:Button ID="btnAddRecord"  

                            CommandArgument="<%# ((GridViewRow)Container).RowIndex %>" 

                            CommandName="AddRecord" runat="server" Text="Add" />
            </ItemTemplate>
        </asp:TemplateField> 
    </Columns>
</asp:GridView>

Now in your code-behind, you can handle the OnRowCommand event and AddRecord command, like this:

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "AddRecord")
    {
        // Get index of row passed as command argument
        int index = Convert.ToInt32(e.CommandArgument.ToString());

        // Your logic here
    }
}
