How To Check Page Validation Error
Apr 4, 2010
An error occur something like this "Page.IsValid cannot be called before validation has taken place. It should be queried in the event handler for a control that has CausesValidation=True and initiated the postback, or after a call to Page.Validate. I make some work around but it didn't work
Here's my code in my Page Load event that an error occur
Code:
if (Request.QueryString["id"] != null)
{
txtID.Text = clsFunction.ReplaceString(Request.QueryString["id"].ToString());
if (!Page.IsValid)
{
Page.Validate();
cmdProceed_Click(sender, e);
}
}
In my page, I have this two validation group so if I am going to re-structure my above code like this
Code:
protected void Page_Load(object sender, EventArgs e)
{
if (Request.QueryString["id"] != null)
{
txtID.Text = clsFunction.ReplaceString(Request.QueryString["id"].ToString());
Page.Validate();
if (Page.IsValid)
{
cmdProceed_Click(sender, e);
}
}
}
I will not encounter the above mentioned error however, my second validation group trigger and the cmdProceed_Click is not executed.

i would very much like to capture certain dal/bll exceptions in my page_error code and turn them into validation errors so they should show up in the validationsummarythis is the code im trying now
[Code]....
the logic is simply to catch only exceptions of type ArgumentException, otherwise it should bubble up (to global.asax handling)what hapens is that after this code block runs, the exception still exists in the system, so it always bubbles up to the global.asaxit there any way to tell asp.net that "its ok, i took care of the exception, just continue with the page"?i tried server.clearerror and context.clearerror but these methods stop the whole page and return a blank empty pagethank you all for your time and patiencep.s. if u have any other ideas 4 improving this code,

My page scrolls down a bit, so the problem is when the ASP.NET validation kicks in (its a server side validation that sets a table row to visible if there was a failed validation for a given input box).The problem is, when there is an error, the page scrolls back to the top.How can I force the page to the bottom? can use <a name="asdf"></name> but the page doesn't refresh normally since its a asp.net image button.

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 search control in my master page with the following validation on the search btn's OnClientClick:
[Code]....
Then in the content page I have various controls with validation and a validation summary. I have few custom validators on the content page like below:
[Code]....
which uses the clientvalidationsfunctions which set the validity of the page.Now when I leave the search box in the header blank and I click the submit btn in the content page it posts me back to same (source) page and while debugging I find that the Page.IsValid is false. But if I write something in the search textbox in the master page and the fill the required fields in the content page and click the submit btn in content page it works fine. Why is that so? My validation groups are different on master page and content page.

I have a form with x fields on - its a signup form on a web page. I use standard validation controls which I use for validating on both client and server side, however I have an additional requirement I don't think is covered by the standard controls. When a user enters an email address and press enter, I validate that the address is not already in the database, by calling a stored procedure. This works fine but it would be great to validate it client side as with all the other entry fields.
I wouldn't know where to start with javascript so I have come up with the following solution. I have put a ontextchanged event on the email textbox and set to autopostback. When the user navigates away from the textbox validation is called and this seems to work ok. My question is have I missed something, and is there an easier soluyion using validation controls or is this an appropriate solution to the problem?

In my application the user uploads three files ( Resume, Cover Letter, Selection Creteria).
I want users not to upload more then 4 MB files, so In my web.confing file I have allowed max of 5 MB. <httpRuntime maxRequestLength="5000"/>. I did this so that I can validate the file and give user a message that they are trying to upload more then 4 MB file.
It all works fine if the user is only uploading resume. But if the user uploads all three files of size 4MB then my validation does not work and it goes to connection time out.
How can i handle the validation to check the file size of all 3 files?

I am CustomValidator to vlidate some data.There are 3 static buttons and some dynamically creating buttons in that page. I just need to check validation when I press the save button.For all other button click I do not want to call the validation. How do I tell that in the Validation function?
<asp:CustomValidator ID="CustomValidator1" runat="server"
ErrorMessage="CustomValidator" ControlToValidate="DropDownList1"
ClientValidationFunction="MyCustomValidation" ></asp:CustomValidator>
function MyCustomValidation(objSource, objArgs)
{
/Proceed if the control pressed is cmdSave button.
var Specialty = document.getElementById("DropDownList1").options[document.getElementById("DropDownList1").selectedIndex].text;
if (Specialty == "Select an option")
{
objArgs.IsValid = false;
}
else
{
objArgs.IsValid = true;
}
}

I have a web form with about 20 fields all validated, rather than use the validation summary control.
I would like a one line alert at the foot of the form that says something along the lines of "errors were found check the fields highlighted with a *" rather than an explanation for each field that has failed validation.
Seem simple enough in theory but i cant work it out.
Is there a line of VB.net code i could use to determine if validation has failed on one or more of my validators and maybe show a label with the "errors were found please check the fields highlighted with a *" message?

I have the following code. What's happening is, on postback, the required attribute for sequence will fire. If it passed, the range check is skipped completely. If it fails, it never gets to the range check either. Have I coded something wrong?
using System.ComponentModel.DataAnnotations;namespace Venue.Models{ [MetadataType(typeof(CategoryMetadata))] public partial class Category { } public class CategoryMetadata { [Required(ErrorMessageResourceType = typeof(Resources.Locale), ErrorMessageResourceName = "sequence_required")] [Range(0, 9999, ErrorMessageResourceType = typeof(Resources.Locale), ErrorMessageResourceName = "sequence_invalid")] public int Sequence { get; set; } [Required(ErrorMessageResourceType = typeof(Resources.Locale), ErrorMessageResourceName = "title_required")] [StringLength(256, ErrorMessageResourceType = typeof(Resources.Locale), ErrorMessageResourceName = "title_invalid")] public string Title { get; set; } }}

We are developing an application where we have a Form to fill by users. Here is the scenario for some fields:Name : Does not contain numbers like 123 but it can be alpha-numeric like mynangal123 but does not contain special charactersOB : Does contain specific formats like mm.dd.yyyy or dd/mm/yyy or yyyy/mm/dd etc. doesn't contain alphabetsTAXID : Can be Numeric but not numbers like it can be "123" but not 123 also it can be T-125Now, as per requirement we have to validate or prompt the user for specific input if he/she did not enter the specific entry. Like if in name User enter 123456 then there should be a messagebox to warn "please enter a valid name"Restrictions : We have a option of Javascript but its not recommendable in most of scenario so, we need to create a custom validators or something else which will solve our problem.

Is there a way to disable request validation on an action without having to add the line <httpRuntime requestValidationMode="2.0"/> to Web.config? I'm currently posting XML to a controller action and get the "A potentially dangerous Request.Form value..." error. Is disabling request validation the only way to get the post to work, or is there some way I can intercept and encode the value that contains XML between the view and the controller action?
