為GridView的刪除行添加刪除確認

------.ASPx  添加：OnRowCreated="GridVIEw1_RowCreated"
    <ASP:AccessDataSource ID="AccessDataSource1" runat="server" DataFile="~/Base.mdb"
            SelectCommand="SELECT [id], [Title], [Classid] FROM [leoWeb_News]"
            DeleteCommand="delete from leoweb_news where id = @id"
        ></ASP:AccessDataSource>
        <ASP:GridView ID="GridVIEw1" runat="server" AllowPaging="True" AutoGenerateColumns="False"
            DataKeyNames="id" DataSourceID="AccessDataSource1" OnRowCreated="GridVIEw1_RowCreated" >
            <Columns>
                <ASP:BoundField DataFIEld="id" HeaderText="id" InsertVisible="False" ReadOnly="True"
                    SortExpression="id" />
                <ASP:BoundField DataFIEld="Title" HeaderText="Title" SortExpression="Title" />
                <ASP:BoundField DataFIEld="Classid" HeaderText="Classid" SortExpression="Classid" />
                <ASP:CommandFIEld ShowDeleteButton="True" />               
            </Columns>
   &nbs

p;    </ASP:GridVIEw>

------------------------------------------------------------------------cs 添加

    protected void GridView1_RowCreated(object sender, GridVIEwRowEventArgs e)
    {
        if (e.Row != null && e.Row.RowType == DataControlRowType.DataRow)
        {
            LinkButton lb = e.Row.Cells[3].Controls[0] as LinkButton;

            //如果是Button按鈕,即 ButtonType="Button" 時
            //則 Button lb = e.Row.Cells[3].Controls[0] as Button;

            lb.Attributes.Add("onclick", "return window.confirm(''刪除確認'')");

        }
    }

 ------------------------------------------------------------------------------------------------

在最終的Html結果源文件中,ButtonType="LinkButton" 時 onclick="return window.confirm(''刪除確認'');" A標記回加上上面這個屬性。
如果：ButtonType="Button"  則 onclick="return window.confirm(''刪除確認'');Javascript:__doPostBack(''GridVIEw1'',''Delete$9'')" 可以看到這個屬性被加到了原來的onclick之前。

知道這些對了解.Net2.0控件執行機理的幫助是很大的。
