I have problem in displaying regularexpressionvalidator error message below the text box. from current code snippet its putting regularExp error msg in separate span block.Rather I want it to appear inside the span block which has text box.

DetailRowText.ascx

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="DetailRowText.ascx.cs" Inherits="Web.UI.UserControls.DetailRowText" ClassName="DetailRowText" %>
 <div class="admin-row">
    <span class="admin-field">
       <asp:TextBox ID="txt" runat="server" Width="200" /> <br />
       <asp:RequiredFieldValidator ControlToValidate="txt" ID="valRequired" CssClass="admin-required" Display="Dynamic" runat="server" EnableClientScript="false"></asp:RequiredFieldValidator>
       <asp:RegularExpressionValidator ControlToValidate="txt" ID="valRegex" CssClass="admin-required" Display="Dynamic" runat="server" EnableClientScript="false" ValidationExpression="\d+"></asp:RegularExpressionValidator>
    </span>
 </div>

A.aspx

 <asp:PlaceHolder ID="placeHolder" runat="server" />

A.aspx.cs

prop = t.GetProperty("Description");
rowText = (UserControls.DetailRowText)Page.LoadControl("~/UserControls/DetailRowText.ascx");
rowText.ID = prop.Name;
rowText.IsRequired = true;
this.placeHolder.Controls.Add(rowText);


prop = t.GetProperty("code");
rowText =(UserControls.DetailRowText)Page.LoadControl("~/UserControls/DetailRowText.ascx");
rowText.ID = prop.Name;
rowText.IsRequired = false;
this.placeHolder.Controls.Add(rowText);

RegularExpressionValidator rankRegExpVal = new RegularExpressionValidator();
rankRegExpVal.Display = ValidatorDisplay.Static;
rankRegExpVal.ControlToValidate = "txt";
rankRegExpVal.ValidationExpression = "^\\d{1,10}$";
rankRegExpVal.CssClass = "admin-required";
rankRegExpVal.ValidationGroup = "ValGrpAllExisting";
rankRegExpVal.Text = LabelManager.GetString(this.GetLanguageResources(), "code", "code_ErrorMessage", this.UserSession.LanguageString);
rankRegExpVal.ErrorMessage = LabelManager.GetString(this.GetLanguageResources(), "EducationLevel", "code_ErrorMessage", this.UserSession.LanguageString);
rowText.Controls.AddAt(rowText.Controls.Count, rankRegExpVal);
