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" /> </td> <td> <div id="divAttachment"> <als:HyperLink runat="server" ID="hyperLink" Text='<%#Eval("Attachment Name") %>' NavigateUrl='<%#Eval("File Path") %>' Target="_blank"></als:HyperLink> <als:Image runat="server" ID="imgDelete" CssClass="hide" /> </div> </td> </tr> </ItemTemplate> <AlternatingItemTemplate> <tr> <td> <als:Image runat="server" ID="img" /> </td> <td> <als:HyperLink runat="server" ID="hyperLink" Text='<%#Eval("Attachment Name") %>' NavigateUrl='<%#Eval("File Path") %>' Target="_blank"></als:HyperLink> </td> <td> <als:Image runat="server" ID="imgDelete" CssClass="hide" /> </td> </tr> </AlternatingItemTemplate> <FooterTemplate> </table> </FooterTemplate> </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...
