这里,我来通过一个Demo来说明这个应用。
需求:
1. 用户在UI上输入一个数值(比如:5),系统动态为用户加载这个数值的Url Address输入域;
2. 用户输入的Url Address内容需要通过Url格式验证;
3. 用户提交输入内容后,系统给出提交的结果
设计如下:
1. Css样式设置:
以下为引用的内容:
<style type="text/css">
.item { margin:10px; border-bottom:solid 1px #CCC; } .item2 { margin:5px; } .input { width:200px; } </style> 2.前台页面代码: <div> <div class="item"> Please input a number: <asp:TextBox runat="server" CssClass="item" ID="txtTextCount"></asp:TextBox> <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="txtTextCount" ValidationGroup="CreateTextBox" Display="Dynamic" ErrorMessage="Required to input content!"></asp:RequiredFieldValidator> <asp:RegularExpressionValidator ID="RegularExpressionValidator1" ControlToValidate="txtTextCount" ValidationGroup="CreateTextBox" Display="Dynamic" runat="server" ErrorMessage="Only number is valid!" ValidationExpression="^\d+$"></asp:RegularExpressionValidator> <asp:Button runat="server" ID="btnCreate" Text="Create TextBox List" ValidationGroup="CreateTextBox" onclick="btnCreate_Click" /> <asp:Button runat="server" ID="btnOK" Text="Get TextBox Content" ValidationGroup="ShowListContent" onclick="btnOK_Click" /> </div> <div runat="server" id="divControls" class="item"></div> <div runat="server" id="divMessage"> </div> </div>2. 前台页面代码:
以下为引用的内容:
<div>
<div class="item"> Please input a number: <asp:TextBox runat="server" CssClass="item" ID="txtTextCount"></asp:TextBox> <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="txtTextCount" ValidationGroup="CreateTextBox" Display="Dynamic" ErrorMessage="Required to input content!"></asp:RequiredFieldValidator> <asp:RegularExpressionValidator ID="RegularExpressionValidator1" ControlToValidate="txtTextCount" ValidationGroup="CreateTextBox" Display="Dynamic" runat="server" ErrorMessage="Only number is valid!" ValidationExpression="^\d+$"></asp:RegularExpressionValidator> <asp:Button runat="server" ID="btnCreate" Text="Create TextBox List" ValidationGroup="CreateTextBox" onclick="btnCreate_Click" /> <asp:Button runat="server" ID="btnOK" Text="Get TextBox Content" ValidationGroup="ShowListContent" onclick="btnOK_Click" /> </div> <div runat="server" id="divControls" class="item"></div> <div runat="server" id="divMessage"> </div> </div>说明, 动态创建的TextBox们将装载到divControls中。
3. 后台代码:
以下为引用的内容:
///<summary>
/// Create textbox list ///</summary> ///<param name="num">textbox list count</param> private void CreateTextBoxList(int num) { HtmlGenericControl div; HtmlGenericControl span; TextBox txt; RegularExpressionValidator rev; for (int i = 0; i < num; i++) { //创建div div = new HtmlGenericControl(); &nbs[1] [2] 下一页
