以编程方式更改ImageUrl onclick ImageButton C＃

Question

我试图更改ImageUrl onclick我的Repeater上的Imagebutton。我必须从代​​码（cs文件）后面更改它，而不是使用jquery或js。

<asp:ImageButton ID="imgLike" ImageUrl="Content/images/thumbsup.png" onclick="imgLike_Click" runat="server" style="width:25px;height:25px" />

这是代码

  protected void imgLike_Click(object sender, ImageClickEventArgs e)
    {
        ImageButton imgLike = (ImageButton)rptinserting.FindControl("imgLike");
        imgLike.ImageUrl = "Content/images/thumbsup1.png";
    }

Answer 1

您将发件人转发回ImageButton并更改ImageUrl。

protected void imgLike_Click(object sender, ImageClickEventArgs e)
{
    ImageButton imgLike = sender as ImageButton;
    imgLike.ImageUrl = "/Content/images/thumbsup1.png";
}
