in my module there are data of students for H.S.C., C.E.T, AND H.S.C+C.E.T. so when i run the gridview page all the data of all streams together is displayed so i sort the data using a dropdownlist...means if 1 select the H.S.C in dropdownlist only the H.S.C students are being displayed.so the problem is when i sort the data by selecting a stream in dropdownlist at that time the error message of required field validator is displayed...
1) I wil select the stream from Dropdownlist and click the "sort button"
2) After the data is been sorted and i will enter the values in the TextBox and if i'll miss any of the textbox blank and i click on the "submit button" after dat the error should be displayed
as "Required".

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 usually only write in ASP, so I am not very familiar with this script. Can anyone tell me how to how to request a querystring so I can use it to pull the image location. Like this.
PhotoCropper.aspx?userid=1090&picid=47
private const string ORIG_SAMPLE_PHOTO_URL = @"/PhotoCropperC/photos/1090/47.jpg";
I have tried just using Request.QueryString["userid"];, but I get the compiler error. Here is my code:
public partial class PhotoCropper : System.Web.UI.Page
{
//Make sure you give the IUSR_MachineName permissions to the directory below
private const string ORIG_SAMPLE_PHOTO_URL = @"/PhotoCropperC/photos/TheDog.jpg";
//private const string ORIG_SAMPLE_PHOTO_URL = "~/photos/TheDog.jpg";
private const string CROPPED_SAMPLE_PHOTO_URL = @"d:/inetpub/sites/dc/cropper/TheDogCropped.jpg";
protected void Page_Load(object sender, System.EventArgs e)
{
if (!Page.IsPostBack)
{
loadPhoto(ORIG_SAMPLE_PHOTO_URL);
}
else {
loadPhoto(CROPPED_SAMPLE_PHOTO_URL);
btnCrop.Visible = !btnCrop.Visible;
}
}

When it comes to field validation, when I use a Compare Validator to make sure a date is a date or a numeric field has a number, I must also use a Required Field Validator to make sure there is something actually enetered. In other words, the Compare Validator allows a blank value even though a blank is not a date or number or whatever.
Is using both a Required Field Validator and a Compare Validator the way to do this or is there some way to make the Compare Validator also require input of some kind?

Issue when setting Display ="Dynamic" for Required Field Validator.Here is my ASP.NET code. Simple. it has a A textbox associated with a required field validator and a submit button.
[Code]....
Do the following
1. Click on Button1
2. RequiredFieldValidator will be shown
3. Type some text in TextBox
4. Use your Mouse(no tab please). and click on the button , you can see that your page does not "POSTBACK" and only the validation gets cleared. you need to
click again the button for Submission of Form.This seems to be a bug by Microsoft when setting the property Display ="Dynmaic" and Is there a easy workaround without changing the intended behavior for this available?

I'm trying to use a field validator to make sure one of my list boxes has a selection before the user is able to proceed to the next page. i'm having is that if the validation message is triggered, all of the buttons on my page loose functionality.Meaning, if I purposely trigger the validation control, I can't get rid of the error message and none of my buttons do anything when clicke after this.
The majority of the HTML:

Is there something that I need to add to the code behind of the page or the Java Script that I'm using?

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"

The problem is, when I click the button it shows a '*' in front of every textbox in odd or even items, instead of validating only the textbox in that item.
How can I validate only the text box inside the item in which the button being clicked resides?

I have a aspx page with a ascx control inside an ascx control and the required field validator is not hit on the action of the page.
The issue is with the 2nd nested ascx control. The field validators in the first ascx control validate correctly, but with the ascx control inside the ascx control there are issues.
The nested ascx control is a repeater control and this may be the reason, but I am unsure.
I'm not exactly sure what question to ask, but I'll list a few below.
How do I attach the field validators up a level to the 1st ascx control?
Is it possible to put required fields into a nested ascx control?

Given the above scenario, I would have thought that submitting the form with a blank ProductId would have been fine because I didn't decorate the ProductId property with [Required]. However I get the error message "The ProductId field is required".
Is there any way to make an Integer property on the model not required?
