改變ImageUrl onclick ImageButton編程C＃

Question

我試圖改變ImageUrl onclick我的中繼器上存在的圖像按鈕。我必須從不使用jquery或js的代碼（cs文件）後面進行更改。在此先感謝

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

這裏是代碼

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

    } 

Answer 1

你施放發送回一個ImageButton的，改變ImageUrl。

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