请看下面代码

Hi all,
Please see below code

<asp:Repeater ID="rptrAddPhotos" runat="server" DataSourceID="AddPhotosDS" OnItemDataBound="rptrAddPhotos_itemDataBound">
<ItemTemplate>                                        
   <asp:LinkButton ID= "lnkAddedPhoto" runat="server">
            XXXXXX
   </asp:LinkButton>
</ItemTemplate>
</asp:Repeater>

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

推荐答案

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.
