推荐答案

如果您想在按钮或图像按钮的OnClick事件中替换图像时避免回发。



您可以使用更新面板异步回发触发器。



您的代码结构将是这样的。

If you want to avoid postback while replacing the image in OnClick event of a button or image button.

You can use Update Panel along with Async Postback Trigger.

Your code structure will be like this.

<asp:UpdatePanel ID="UpdatePanelID" runat="server">
   <ContentTemplate>


            //YOUR Image Button/Button

   </ContentTemplate>
                <Triggers>
                         <asp:AsyncPostBackTrigger ControlID="Button/imageButtonID" EventName="Click" />
                </Triggers>
 </asp:UpdatePanel>

希望它会有所帮助.. :)

我的HTML代码：

my html code :

  <asp:updatepanel id="UpdatePanel2" runat="server" xmlns:asp="#unknown">
    <contenttemplate>
        <div>
            <asp:textbox id="editor" runat="server" cssclass="bord" width="40%" maxlength="80">
                ValidationGroup="1" TabIndex="1"></asp:textbox>
        </div>
<pre lang="vb"><asp:Button ID="Button1" runat="server" Text="send " OnClick="Button1_Click"
              CssClass="btn" Width="10%" ValidationGroup="1"/>

align =center>

< asp：imagebutton id =ImageButton1runat =serverimageurl =〜/ yahoo / 1.gifonclick = ImageButton1_Click>

< asp：imagebutton id =ImageButton2runat =serverimageurl =〜/ yahoo / 2.gifimag ealign =中>

OnClick =ImageButton2_Click/>

align="center">
<asp:imagebutton id="ImageButton1" runat="server" imageurl="~/yahoo/1.gif" onclick="ImageButton1_Click">
<asp:imagebutton id="ImageButton2" runat="server" imageurl="~/yahoo/2.gif" imagealign="Middle">
OnClick="ImageButton2_Click" />

<触发器> < asp：asyncpostbacktrigger controlid =ImageButton1eventname =Click>





标签会显示内容TextBox

<triggers> <asp:asyncpostbacktrigger controlid="ImageButton1" eventname="Click">


The labels will show you the contents of the TextBox

 public string chg(string s)
        {
           
            s = s.Replace("[a]","<img src="yahoo/1.gif">");           
            s = s.Replace("[b]", "<img src="yahoo/2.gif">");
   return s;
        }
label.text=user + ":" + chg(editor.Text.ToString());
</img></img>
