你需要从 ItemTemplate 中找到 LinkBut​​ton Repeater 。

试试这个：

You need to find LinkButton from ItemTemplate of Repeater.
Try this:

protected void rptrAddPhotos_itemDataBound( object sender, RepeaterItemEventArgs e ) {
    Label lnkAddedPhoto= (Label)e.Item.FindControl( "lnkAddedPhoto" );
    lnkAddedPhoto.Click += new EventHandler(lnkAddedPhoto_onClick );
}

protected void lnkAddedPhoto_onClick( object sender, EventArgs e ) {

}

创建动态事件和控件总是会产生viewstate问题。在您的aspx中创建您的事件。

Creating dynamic events and controls always creates problem with viewstate. Create your events inside your aspx.
