在转发器Asp.net中尝试图像按钮 [英] trying Image Button in repeater Asp.net

问题描述

我在Repeater中使用imageButton时遇到问题.我尝试了很多方法，但没有解决问题.我使用repeater item命令仍然无法正常工作.当我单击imageButton时，什么也没有发生.

I have a problem using imageButton in a Repeater.I tried alot of method and didnt fix the problem.I used the repeater item command still not working.when i click on the imageButton nothing happen.

< asp:ImageButton ID ="ImageButton1" runat ="server" Height ="200px" Width ="150px" ImageUrl ='<％#〜/imageHandler.ashx?Mid =" + DataBinder.Eval(Container.DataItem，"Mid")％>'CommandName ="img" CommandArgument ='<％#Eval("Mid")％>'/>

  protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
    {
        ModalPopupExtender mpe = (ModalPopupExtender)e.Item.FindControl("mpe");
        LinkButton Lbtn = (LinkButton)e.Item.FindControl("LinkButton1");
       switch (e.CommandName)
        {
            case "btn1":

                Session["id"] = Lbtn.CommandArgument.ToString();

                mpe.Show();

                break;
            case "img":
                Response.Write("event is fired");
                break;

            default:
                break;

推荐答案

看看下面的代码段.您的LinkBut​​ton代码似乎正确，但是您是否将 OnItemCommand 添加到了Repeater中?

Take a look at the snippet below. Your LinkButton code seems to be correct, but did you add the OnItemCommand to the Repeater?

<asp:Repeater ID="Repeater1" runat="server" OnItemCommand="Repeater1_ItemCommand">
    <ItemTemplate>
        <asp:ImageButton ID="ImageButton1" runat="server" CommandName="img" CommandArgument='<%#Eval("Mid") %>' />
    </ItemTemplate>
</asp:Repeater>

后面的代码

protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    string commandArgument = e.CommandArgument.ToString();

    if (e.CommandName == "img")
    {
        Response.Write("event is fired: " + commandArgument);
    }
    else if (e.CommandName == "btn1")
    {
        Session["id"] = commandArgument;
    }
}
