在MVC项目表单使用Web窗体的用户控件 [英] Using webform user control on webform in MVC Project
问题描述
我使用的是单web.forms页面上的服务器控件。我不得不使用它，因为服务器控件的web.forms页面上这种控制，虽然这实际上是一个MVC项目。所以，我创建了一个文件夹web.forms，把我的新的一页了。然后，我从签名控件复制的例子code。我收到以下错误：
的基类包括字段ctrlSign，但其类型（WebSignatureCapture.SignatureControl）不与控件的类型（ASP.signaturecapture_signaturecontrol_ctlsignature_ascx）兼容。
我知道code工作，因为如果我从服务器控件中删除ID属性，它不再给我这个错误，我的控件呈现。但我需要的属性的ID，所以我可以执行的事件后...任何想法，为什么？
我使用的 这 签名的控制。这里的web.forms code ...

打开用户控件的.ascx标记文件。它应显示是这样的：
＆LT;％@控制
语言=C＃
AutoEventWireup =真
codeFILE =ctlSignature.ascx.cs
继承=WebSignatureCapture.SignatureControl.ctlSignature％GT;
修改为：
＆LT;％@控制
语言=C＃
AutoEventWireup =真
codeBehind =ctlSignature.ascx.cs
继承=WebSignatureCapture.SignatureControl.ctlSignature％GT;
的通知codeFILE - > codeBehind
I am using a server control on a single web.forms page. I have to use this control on a web.forms page since its a server control, although this is actually a MVC project. So I created a web.forms folder and put my new page in it. I then copy the example code from the signature control. I get the following error:
The base class includes the field 'ctrlSign', but its type (WebSignatureCapture.SignatureControl) is not compatible with the type of control (ASP.signaturecapture_signaturecontrol_ctlsignature_ascx).
I know the code works because if I removed the ID attribute from the server control, it no longer gives me this error and my control renders. But I need the attribute for the ID so I can perform is post event... Any ideas why?
I am using this signature control. Here's the web.forms code...
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Index.aspx.cs" Inherits="KahunaCentralTIDRevamp.SignatureCapture.Index" %>
<%@ Reference Control="~/SignatureCapture/SignatureControl/ctlSignature.ascx" %>
<%@ Register TagPrefix="uc" TagName="Signature" Src="~/SignatureCapture/SignatureControl/ctlSignature.ascx" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<html>
<head>
<title>Signature Application Demo</title>
</head>
<body>
<form id="frmOrder" method="post" runat="server">
<div>
Please Sign Below:
</div>
<div>
<uc:Signature ID="ctrlSign" SignHeight="150" SignWidth="300" SignatureCodePath="~/SignatureCapture/SignatureControl/"
SavePath="~/SignatureCapture/" SignatureFileFormat="Gif" runat="server" />
<%-- <uc:Signature id="ctlMySignature" PenColor="Red" PenWidth="2" BackColor="Yellow" SignWidth="300" SignHeight="150"
SavePath="~/Signatures/" SignatureCodePath="~/SignatureControl/" SignatureFileFormat="Gif" Runat="server"></uc:Signature>--%>
</div>
<div>
<input type="button" value=" Re-Sign " onclick="ClearSignature();">
<asp:Button runat="server" ID="btnSave" Text=" Save " onmousedown="document.getElementById('btnSave').value = 'Wait...';"
OnClientClick="DirectSave();" OnClick="btnSave_Click" />
</div>
</form>
<script language="javascript" type="text/javascript">
// This is the method that is directly called, this will save signature
// and then call server code to do further processing. You can change
// the delay of 5 seconds as per your needs
function DirectSave() {
SaveSignature();
var date = new Date();
var curDate = null;
// delay of 5 seconds, 5000 milisecons, change as per requirement
do { curDate = new Date(); }
while (curDate - date < 5000);
return true;
}
</script>
</body>
</html>
Open the .ascx markup file of the user control. It should read something like this:
<%@ Control
Language="C#"
AutoEventWireup="true"
CodeFile="ctlSignature.ascx.cs"
Inherits="WebSignatureCapture.SignatureControl.ctlSignature" %>
Modify it to:
<%@ Control
Language="C#"
AutoEventWireup="true"
CodeBehind="ctlSignature.ascx.cs"
Inherits="WebSignatureCapture.SignatureControl.ctlSignature" %>
Notice CodeFile -> CodeBehind.
