推荐答案

如果您的事件代码是这样的，

直接事件.

Hi,

if your event code is like this,

for direct event.

protected void MakeImg1Main(object sender, EventArgs e)
{
   //Then try like this.
   string ID = ((ImageButton)sender).ID;
   string CLientID = ((ImageButton)sender).ClientID;
}

与数据列表一起，为数据列表添加项目命令事件.

添加命令名称

with datalist, add item command event for datalist.

add the command name

<asp:ImageButton ID="Img1" ImageUrl='<%#Eval("ProductImage") %>' runat="server" Width="30px" Height="30px" CommandName="Image" />

//In ItemCommand Event,
if(e.CommandName == "Image")
{
  string ID = ((ImageButton)e.CommandSource).ID;
  string CLientID = ((ImageButton)e.CommandSource).ClientID;
}

希望对您有所帮助.

Hope it helps.

您好，

将点击事件作为MakeImg1Main授予所有图像按钮，并从点击事件类型中将您的发件人投射到图像按钮并获取其ID ...

就像

Hi,

Give click event as MakeImg1Main to all imagebuttons and from the click event type cast your sender to imagebutton and get its id...

like

private void MakeImg1Main(object sender,EventArgs e)
{
   ImageButton img=(ImageButton)sender;

// this will get you the id of the image button clicked
   Response.Write(img.Id.ToString());
}

希望对您有帮助.
