我正在尝试在我的ASP .net应用程序中使用一些Ajax工具包控件,但似乎它不起作用。
我想在我的表单中使用Modal弹出窗口,但必须在弹出窗口中显示的面板,在浏览器上显示,按钮不执行任何操作。为什么它不起作用?
我正在编写VB .net并且有我的样本:
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="FieldItem.ascx.vb" Inherits="DataBaseWorker.FieldItem" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
<link href="../Styles/FieldItem.css" rel="stylesheet" type="text/css" />
<div class="TitleDiv">
<span runat="server" id="lblIndex" class="IndexSpan">111</span>
<span runat="server" id="lblDelimeter" class="IndexSpan"> ) </span>
<span runat="server" id="lblTitle" class="TitleSpan">test</span>
<span runat="server" id="lblActiveState" class="TitleSpan">test</span>
<span runat="server" id="lblAlias" class="TitleSpan">test</span>
<asp:Button CssClass="buttonControl" ID="btnDelete" runat="server" Text="test" />
<asp:Button CssClass="buttonControl" ID="btnEdit" runat="server" Text="test" />
<asp:Button CssClass="buttonControl" ID="btnAddAlias" runat="server" Text="test" />
<asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server"
CancelControlID="btnCancel" OkControlID="btnSubmitAlias" TargetControlID="btnAddAlias"
PopupControlID="addAliasPlace" Drag="false">

</asp:ModalPopupExtender>
</div>
<asp:Panel Visible="false" runat="server" id="addAliasPlace" >
<div class="AddAliasDiv">
<asp:TextBox ID="txtAliasName" CssClass="TitleSpan" runat="server"></asp:TextBox>
<asp:Button CssClass="buttonControl" ID="btnSubmitAlias" runat="server" Text="ثبت" />
<asp:Button CssClass="buttonControl" ID="btnCancel" runat="server" Text="بازگشت" />

我可以描述当我使用模态弹出时我做了什么。
<asp:Button ID="btnshowpopup" runat="server" Style="display: none;" />
<act:ModalPopupExtender ID="test" runat="server"
TargetControlID="btnshowpopup"
PopupControlID="addAliasPlace"
CancelControlID="btnModalCancel"
BackgroundCssClass="modalBackground"
BehaviorID="addAliasPlace">
</act:ModalPopupExtender>
在我使用js显示模态后,例如:
$find("addAliasPlace").show();

如果是用户控件,则必须使用System.Web.UI.ScriptControl。
来自pietschsoft.com: ScriptControl基类在派生控件的PreRender阶段测试ScriptManager控件的页面。 ScriptControl基类还确保派生控件调用ScriptManager控件的方法以在Render事件期间注册脚本。这包括在调用Render方法时为ScriptControl注册ScriptDescriptor对象。除非呈现ScriptControl本身,否则Render方法确保不呈现ScriptDescriptor对象。这使得ScriptControl可以在封闭的WebPart控件中工作。
