更改gridview的按鈕文本

Question

我有一個網格視圖，其中包含模板字段中的按鈕。我想在按鈕點擊事件完成時更改按鈕文本。有人可以給我一個示例代碼。

預先感謝

下面是代碼使用RowCommand（）在GridView的採樣位。

ASPX

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" onrowcommand="GridView1_RowCommand"> 
    <Columns> 
     <asp:TemplateField> 
      <ItemTemplate> 
       <asp:Label ID="lbl1" runat="server"></asp:Label> 
      </ItemTemplate> 
     </asp:TemplateField> 
     <asp:TemplateField ShowHeader="False"> 
      <ItemTemplate> 
       <asp:Button ID="Button1" runat="server" CausesValidation="false" CommandName="MYCOMMAND" Text="My Text!" /> 
      </ItemTemplate> 
     </asp:TemplateField> 
    </Columns> 
</asp:GridView> 

C＃

protected void Page_Load(object sender, EventArgs e) 
{ 
    if (!IsPostBack) 
    { 
     List<string> lst = new List<string>() { "asd", "xxx" }; 
     GridView1.DataSource = lst; 
     GridView1.DataBind(); 
    } 
} 

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e) 
{ 
    if (e.CommandName == "MYCOMMAND") 
    { 
     Button Button1 = (Button)e.CommandSource; 
     if (Button1 != null) 
      Button1.Text = "changed text.."; 
    } 
}
