模型弹出窗口无法找到目标ID ''btn''输入类型按钮

请帮帮我..

解决方案

我相信你需要让它成为一个服务器控件。它在服务器上不存在。

hi，

< input type =按钮id =btnvalue =Okayrunat =server/> 

或者你可以使用asp按钮。

My aspx code is:

<form id="form1"  runat="server">
    <div>
 <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"/>

            <asp:UpdatePanel ID="UpdatePanel1" runat="server">
           
             <contenttemplate>
             <input type="button" id="btn" value="Okay" />
  <asp:ModalPopupExtender runat="server" 

                        ID="modelPopupExtender1" 

                        TargetControlID="btn"

                        PopupControlID="popUpPanel" 

                        

                        BackgroundCssClass="modalBackground">
 

<asp:Panel ID="popUpPanel" runat="server" CssClass="pnl" Visible="false">
 <div style="font-weight: bold; border: Solid 3px Aqua; <br mode=" hold=" />                                background-color: AliceBlue">
 
 <asp:Label runat="server" ID="myThrobber" Style="display: none;"><img align="absmiddle" alt="" src="images/uploading.gif"/>
                <asp:AjaxFileUpload ID="AjaxFileUpload1" 

                    runat="server" 

                    OnUploadComplete="AjaxFileUpload1_UploadComplete"

                    OnClientUploadError="uploadError" 

                    OnClientUploadComplete="uploadComplete"

                    ThrobberID="myThrobber"

                    MaximumNumberOfFiles="1"

                    AllowedFileTypes="" 

                    class="name_text1" 

                    Width="200px" />
                <asp:Label ID="Label1" runat="server" Text="">
                <asp:Button ID="BtnClose" runat="server" Text="Close" 

                    OnClientClick="Closepopup()"/>
                
                <asp:Label ID="Label2" runat="server" Text="">
 
                <br />
    
    </form>

Model popup is not Able to find out target id ''btn'' input type button
please help me..

解决方案

I believe you need to make it a server control. It does not exist, on the server.

hi,

<input type="button" id="btn" value="Okay" runat="server" />

or you can use asp button.
