Repeater c＃asp.net [英] Repeater c# asp.net

问题描述

我的页面上有一个转发器控件，带有图像（img）控件，超链接控件和图像（imgdelete）控件

不同。

悬停时我已经将图像（imgdelete）控件视为可见的超链接。

我想向那个（imgdelete）添加一个onclick事件，在那个点击我要删除该转发器中的整行。 br $> b $ b



我怎么能继续？



我的代码是如下：

< pre lang =xml>< als：Repeater ID =rptAttachmentNewrunat =serverOnItemDataBound =rptAttachmentNew_ItemDataBound> 
< HeaderTemplate> 
< table> 
< / HeaderTemplate> 
< ItemTemplate> 
< tr> 
< td> 
< als：Image runat =serverID =img/> 
< / td> 
< td> 
< div id =divAttachment> 
< als：HyperLink runat =serverID =hyperLinkText ='<％＃Eval（Attachment Name）％>'
 NavigateUrl ='<％＃Eval（ 文件路径）％>'目标=_空白>< / als：HyperLink> 
< als：Image runat =serverID =imgDeleteCssClass =hide/> 
< / div> 
< / td> 
< / tr> 
< / ItemTemplate> 
< AlternatingItemTemplate> 
< tr> 
< td> 
< als：Image runat =serverID =img/> 
< / td> 
< td> 
< als：HyperLink runat =serverID =hyperLinkText ='<％＃Eval（Attachment Name）％>'
 NavigateUrl ='<％＃Eval（ 文件路径）％>'目标=_空白>< / als：HyperLink> 
< / td> 
< td> 
< als：Image runat =serverID =imgDeleteCssClass =hide/> 
< / td> 
< / tr> 
< / AlternatingItemTemplate> 
< FooterTemplate> 
< / table> 
< / FooterTemplate> 
< / als：Repeater>< / pre> 

解决方案

试试这个



为Repeater附加事件

 onitemcommand =rptAttachmentNew_ItemCommand

为图像控件添加命令名称和参数

< asp：image runat = servercommandname =deletecommandargument ='<％＃Eval（Id）％>'id =imgDeletexmlns：asp =＃unknown/> 

处理代码中的事件

 protected void rptAttachmentNew_ItemCommand（object source，RepeaterCommandEventArgs e）
 {
 if（e.CommandName ==delete）
 {
 int id = Convert.ToInt（e.CommandArgument）; 
 //使用删除逻辑的ID 
} 
} 

希望这会有所帮助。 ..

I have a repeater control on my page with an image(img) control ,hyperlink control and an image(imgdelete) control
in different .
On hover of that hyperlink i have made the image (imgdelete) control as visible.
I want to add an onclick event to that (imgdelete) and on that click i want to delete the entire row in that repeater.


how can i go ahead??

my code is as follows:

<pre lang="xml"><als:Repeater ID="rptAttachmentNew" runat="server" OnItemDataBound="rptAttachmentNew_ItemDataBound">
                                           <HeaderTemplate>
                                               <table>
                                           </HeaderTemplate>
                                           <ItemTemplate>
                                               <tr>
                                                   <td>
                                                       <als:Image runat="server" ID="img" />

                                       </als:Repeater></pre>

解决方案

Try this

Attach event for Repeater

onitemcommand="rptAttachmentNew_ItemCommand"

Add Command Name and Argument for the Image control

<asp:image runat="server" commandname="delete" commandargument='<%#Eval("Id")%>' id="imgDelete" xmlns:asp="#unknown" />

Handle the event in code behind

protected void rptAttachmentNew_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    if (e.CommandName == "delete")
    {
        int id = Convert.ToInt(e.CommandArgument);
	//use the id for the delete logic
    }
}

Hope this helps...
