RegularExpression Validator Doesn't Display Error Message?
Mar 17, 2010
I have a regular expression validation control initialized to validate a textbox control. I want users to be able to enter U.S. Currency values ($12,115.85 or 1500.22 etc.). I found a regular expression off of regexlib website that does the trick. The validation control seems to be working except for one crucial thing. If invalid data is entered, the validation text dispalys (a red "*" next to the textbox), but the page will still submit and the error message won't pop up... I thought that the error message is supposed to display and the page won't submit if the validation control detects invalid data. Isn't this automatic with ASP .NET? I have searched extensively on how to create validation controls, but haven't found anything different than what I am already doing. Can anyone tell me what I am doing wrong here?
<asp:TextBox ID="txtActualCost" runat="server" Width="120px" CausesValidation="true"></asp:TextBox>
<asp:RegularExpressionValidator ID="regExValActualCost"
ControlToValidate="txtActualCost"

i am working on web-form for which I have set the validation summary showmessagebox = "true". I have two required field validators, which trigger on a checkbox's OnCheckedChanged event....now my problem is, when I hit submit, the page does not submit if I do not enter any values in the text boxes..which is correct behavior but it does not point out to the error or does not display the message box...i have to scroll up to see what is wrong with he page and then try to enter the values...I do not understand why my message box does not show up or at least why my setfocusonerror which is set to true does not show me the text boxes. find my code below.....

I wanted to write a regular expression using the ASP.Net RegExp validator that would ensure a field contains only numeric and decimal values, and at least one character.
^[0-9]{1,40}(.[0-9]{1,2})?$
Essentially: [0-9]{1,40} - meaning at least one to 40 numeric characters.The ASP.Net regexp validator does not fire for an empty field - where there is not at least one character.

I am using a compare validator control and also a ajax validatorcallout extender control for data check on a field.
Both of them work well...but only the ajax call out extender pop up error message should display ... right now I have both of them displaying.. it defeats the purpose of having calloutextender, if I am displaying the comparevalidatror message anyway on the webpage.
How do make it so that only the pop up calloutextender ajax is triggered and not the comparevalidator error message.

I have a requirement that one of multiple fields is required. Using custom validator the even fires, false is returned, but no error message is display and the form validates. What am I missing? I have tried with and without ValidationSummary.
<asp:CustomValidator ID="CustomValidator1" OnServerValidate="validatePhone" EnableClientScript="false" runat="server" ErrorMessage="Home or Cell Phone is Required" ></asp:CustomValidator>
<asp:ValidationSummary ID="ValidationSummary1" DisplayMode="BulletList" runat="server" ForeColor="Red" Font-Size="X-Small" Font-Bold="true" />
protected void validatePhone(object sender, ServerValidateEventArgs e)
{
e.IsValid = string.IsNullOrEmpty(txtCellPhone.Text) && string.IsNullOrEmpty(txtHomePhone.Text) ? false : true;
}

I have one doubt i.e i want to display the error message for the validator controls all the times regardless of whether one has entered a value or not. In my case i'm using few required field and custom validator controls.
By using Page.Validate() method i'm able to display the error message for all the controls , but this doesn't work in case the field has any value in it.
Please suggest if there is any workaround for this to display the error mesages for the fields with validator controls all the time.

I've got a booking form which allows users to pick dates. User clicks FromDate button which activates calendar control, they select date from calendar which then populates a textBox. I have a compare validator which checks that the SelectedDate is greater than the current date, if the SelectedDate is in the past then the validator fires error message. This works as fine, however, when the validator fires it disables the FromDate button so the user is unable to pick another date from the calendar as the focus goes to the TextBox which is being validated - how do I get around this? Here's the code:

I have a custom validator:
<asp:CustomValidator ID="QuestionValidator" runat="server" ErrorMessage="Please select an option" ClientValidationFunction="QuestionValidator_ServerValidate" OnServerValidate="QuestionValidator_ServerValidate" ValidateEmptyText="true"></asp:CustomValidator>

When I run the page, there is no validation and no error message. Please can you point out where I am going wrong, I'm suspicious it is at Page.Master.FindControl("form1").Controls.I have previously done such validation by looping through controls via form1.controls but this is unavailable as the page uses a form passed down via the master page.

I have an aspx page with lots of controls on it. I am using a custom validator control (with the serverside validation). Is there a way to display the error message on the validation summary without writing Javasccript. I am a beginner in .NET and am not fluent in Javascript. This is the custom validator HTML
<asp:CustomValidator ID="CustomValidator1" runat="server" ErrorMessage="Invalid Date"
ControlToValidate="txtDate" OnServerValidate="ValidateDate_ServerValidate" ValidationGroup="vgSetUp"
></asp:CustomValidator>
This is the utility method am trying to validate for the entry on the UI, so that it takes dates only in these described formats If the user enters date in any other format, this method returns returns the Datetime.Mivalue(1/1/0001)
public DateTime GetFomattedDate(string dateString)
{
try
{
string[] formats = {
"MMddyyyy", // These are the accepted date formats for the UI
"MM/dd/yyyy",
"M/d/yyyy",
"yyyy/MM/dd",
"yyyy/M/d"
};
DateTime EffDate = DateTime.MinValue;
if ( DateTime.TryParseExact(dateString,formats, null, System.Globalization.DateTimeStyles.None, out EffDate))
{
return EffDate;
}
}
catch (Exception)
{
throw;
}
return DateTime.MinValue;
}
This is my customvalidator event handler(code behind)
protected void ValidateDate_ServerValidate(object source,servervalidate eventargs args)
{
args.IsValid = GetFomattedDate(args.Value) ==DateTime.MinValue? false:true;
}
I am able to validate it properly, but I cannot display the error message in the validation summary along with other messages. Anyone who is expert on Javascript can Help with the javascript function?

We're trying to write an error tracking solution for our sites and ran into something interesting. Sometimes the error exception includes the actual file and line number that the error occurred on and other times it doesn't. Is there a setting somewhere that we need to change to enable the file and line number to be returned? The two situations are each on a different server. Do we need to change something on the server?
Examples, with error file and line number:
System.IndexOutOfRangeException: Intro at System.Data.ProviderBase.FieldNameLookup.GetOrdinal(String fieldName) at System.Data.SqlClient.SqlDataReader.GetOrdinal(String name) at System.Data.SqlClient.SqlDataReader.get_Item(String name) at AccountUser.get_PracticeInfo(String sUserName) in C:xxxxxxxxxxxxeta.xxxxxxx.comAccountUser.vb:line 106
Without line number:
System.NullReferenceException: Object reference not set to an instance of an object. at Dealers_Toolbox_UserEdit.LoadRoles()

All the examples and websites i have looked at redirect a user to the error.aspx page when an error occurs. How do you just display a friendly error message on the page the user is viewing saying something like "Sorry unable to do whatever" I've tried using a try catch block on my class that executes a stored procedure and put another try catch on the controller, but this does not work and i still get the default error message (System.InvalidOperationException was unhandled by user code) My code is below:
[Code]....
So how can i just return ViewData["SqlError"] message in page.

I am trying to handle the unhandled exceptions in my project.I tried with this following code in my web.config filebut it is not at all redirecting to an error page which i have created instead of that it is throwing an exception in my code itselef. How to print the error description over therein my custom error page.
---------------------------------------------------------------------------------------------------
<sys.web>......<customErrors mode="On" defaultRedirect="~/Error.aspx"></customErrors>...</sys.web>
---------------------------------------------------------------------------------------------------
And even i tried in Global.asax page in Application_Error() method like below
Exception ex = Server.GetLastError();Response.Redirect("~/Error.aspx?errmsg="+ex.message);Server.ClearError();
And in my Error.aspx.cs page i have placed a label and i have written code like this
protected void Page_Load(object sender, EventArgs e) {
Label1.Text=Request["errmsg"];
}
But it is not getting redirected my error page and not displaying anything on it.
