.net - Validator Throwing Error On One Of Dynamic JS Pages?
Sep 8, 2010
I have the following RegularExpressionValidator on one of my pages:
<asp:RegularExpressionValidator ID="RegularExpressionValidator2" runat="server"
ControlToValidate="InKindTextBox"
ErrorMessage="The value entered for 'Cash' must be in a number format. Examples: 500.00, 500, $500, $50,000 or $500.00"
ValidationExpression="(?n:(^$?(?!0,?d)d{1,3}(?=(?<1>,)|(?<1>))(k<1>d{3})*(.dd)?)$)" >
But when it tries to validate it throws the error below from one of my dynamic JS pages.When I run this regex through regex texter it works fine. Am i doing something wrong here?

<asp:CustomValidator ID="CustomValidator1" runat="server" ClientValidationFunction="fcnValid1"
ErrorMessage="" Display="None" ValidateEmptyText="True">
</asp:CustomValidator>

I'm working on running aspnet_compiler as a post-build even on my Visual Studio 2010 MVC2 application. Every time I run it, I get this error:
The CodeDom provider type "Microsoft.VJSharp.VJSharpCodeProvider, VJSharpCodeProvider, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" could not be located.
I have no J# in my solution. The J# 2.0 redistributable package is installed, and I have no .java files of any kind in my solution, although I have a lot of .js files.

I'm passing parameters (over 30 in all) from a system.data.dataset into a tableadapter insert method, but I'm getting an "Input string was not in a correct format" exception.The error points to the method that is throwing, which is great, but is there a way I can tell exactly which parameter is throwing the error?(Sorry about the code formatting -- I fought with it for 5 minutes before giving up)

I am facing a problem with JQuery Validation...
Its working fine for me on my machine and not throwing any errors...
Once I pushed it to Test or Dev servers its throwing this error: '$.validator' is null or not an object
I have no idea how to deal with it...all my validations are not working and directly going for server side validations...
its throwing this error here:
$.validator.addMethod("CheckDOB", function (value, element) {//some code});

I've got a simple detailsview on a webpage for viewing, adding, and updating inspectors. Since it is a simple details view I'm just used the datasource select, update, delete, and insert commands. When I debug the page it populates the detailsview appropriately and allows me to page through the inspectors but when I try to update a field I'm getting the implicit conversion error in the attached doc. Below is my detail view markup. I was thinking the error is caused by the checkbox type being boolean while the SQL type for "Active" is bit but I've tried to use various conversion methods and can't seem to get them to work.
Code:
<asp:DetailsView ID="dvInspectors" runat="server" AllowPaging="True"
AutoGenerateRows="False" DataKeyNames="InsID" DataSourceID="InspectInfo"
Height="50px" Width="212px">
<Fields>
<asp:TemplateField HeaderText="Insp ID" InsertVisible="False"
SortExpression="InsID">

when a user enters a bad email I am doing a check on this and throwing an exception message as follows, this works fine on the test site but for some reason the same code on the live site gives a "internal server error" (http code 500). The code below:
[Code]....
not certain why this is happening, I assume that it's some server or config difference between the test and live sites. has anyone seen this before? For a quick fix i'm registering javascript alert and showing the same text so it works but I would like to figure out why the code above is not working.

I have a UserControl which contains a TextBox and a CustomValidator. I would like to set the CustomValidator.ServerValidate to a method in the page that contains the UserControl I found this code which will allow me to dynamically set the custom validators validation function: cusvCustom.ServerValidate += new System.Web.UI.WebControls.ServerValidateEventHandler(MethodName);
The problem is that a string value won't work there. It needs to be a reference to the method. Is it possible to use reflection (or some other method) to get a valid reference to the parent controls method using only the string name of it? The reason I want to use the string value of the method name is so I can place the control on the page thusly: <uc1:TextBoxField ID="tbUserName" runat="server" CustomValidationMethod="ValidateUserName" />
WebUserControl.ascx
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="WebUserControl.ascx.cs" Inherits="WebApplication1.WebUserControl" %>
<asp:CustomValidator ID="CustomValidator1" runat="server" ErrorMessage="Custom Validation Failed" OnServerValidate="CustomValidator1_ServerValidate" />
<asp:TextBox ID="TextBox1" runat="server" />
<asp:Button ID="Button1" runat="server" Text="Submit" CausesValidation="true" />
WebUsecControl.ascx.cs
using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace WebApplication1
{
public partial class WebUserControl : System.Web.UI.UserControl
{
public ServerValidateEventHandler Validating;
protected void CustomValidator1_ServerValidate(object sender, ServerValidateEventArgs e)
{
if (Validating != null)
Validating(sender, e);
}
}
}
TestPage.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="TestPage.aspx.cs" Inherits="WebApplication1.TestPage" %>
<%@ Register Src="~/WebUserControl.ascx" TagName="WebUserControl" TagPrefix="uc1" %>

<div>
<uc1:WebUserControl ID="WebUserControl1" runat="server" OnValidating="WebUserControl1_Validating" />

</body>
</html>
TestPage.aspx.cs
using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace WebApplication1
{
public partial class TestPage : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//WebUserControl1.Validating += WebUserControl1_Validating;
}
protected void WebUserControl1_Validating(Object sender, ServerValidateEventArgs e)
{
e.IsValid = false;
}
}
}
I did some research and I found Type.GetMethod and MethodInfo but I can't get them to work. Primarily because I don't know the type of the parent control and can't figure out how to get it. EDIT: My code for matt-dot-net. As you can see it's almost an exact duplicate of your code. For whatever reason it does not work for me as I have it here. When I click on the button the page reloads and is the same. When I un-comment the one line though and click the button then I see the error message.

I have the absolutely most simple setup imaginable. A single table defined in an Entity model in ASP.net v4, the model is bound directly to a GridView with AutoGenerateEditButton enabled.However, each time I hit edit, then save, the page throws the error "Update is disabled for this control" for which I cannot find a solution.What is causing this error? What can do to resolve it?
<%
<asp:GridView ID="MenuItemsGrid" runat="server"
DataSourceID="gridDataSource"
AutoGenerateEditButton="true"
AutoGenerateColumns="true">
</asp:GridView>
<asp:EntityDataSource ID="gridDataSource" runat="server"
ConnectionString="name=dataEntitiesModel"
DefaultContainerName="dataEntities"
EntitySetName="MenuItems" />

jQuery validation is working fine on my machine, when i pushed it to test server it won't it's throwing some errors which is kind of surprising.These are the errors I am getting: $.validator is null or not an object...I've never gotten this error before and it throwing an error when I declared a variable like var isValid.I don't know what to do. I am doing the custom validation methods not in the document.ready(). Does this cause this error? I wonder because all jquery validations are passing and hitting the server side validations.

I have a site where most of my pages are arranged in business area folders, e.g. Activations, Outdoors, Branding. Each folder has a small web.config that protects the contents against access by people without a role for that business area.
However, basic admin for most business areas is done via Dynamic Data pages. These are only basically protected by not appearing in the menu unless the user has the correct role, but they are still accessible directly via URL, because of the {table}/{Action} routing used by Dynamic Data. What can I do to protect these pages against direct access?
