How To Extend Server-side Validation Controls To Raise An Event If Validation Fails
Feb 23, 2010I am using ASP.NET's server-side validation. In the page_load event I'm calling Page.Validate(), and if Page.IsValid is not true I'm then polling the controls to figure out which ones are not valid, and then determining what actions to take.It would be much easier if each control would raise an event as validation fails, allowing me to take action for that particular control. I'm very much a naive programmer when it comes to validation, but is there a way to extend these controls so that a validation error raises an event?
View 1 RepliesWeb Forms :: How To Use CompareValidator Validation Control
Jan 11, 2011I have 2 text boxes in which I am comparing the numeric value of one to the other. At first it works fine and I get the appropriate error message. But eventually as i plug in different numbers although I should be getting an error message I stop getting one. Is there something going on behind the scenes to fire the error message than I am unaware of. Also the error message fires some time when the value is less than the value of another control and equal to the value. I only want it to fire when it is less than the value of the other control.

View 2 RepliesCompareValidator Currency Check Does Not Work With French Formatted Numbers?
Oct 8, 2010I have a salary TextBox and an associated CompareValidator, which is setup as follows:
<asp:CompareValidator ... Operator="DataTypeCheck" Type="Currency" />
I fill the TextBox with a formatted string out of the database:
txtSalary.Text = myObject.Salary.ToString("N2")
When a user accesses the page using a French culture (such as fr-ca), the ToString method will put 80 000,00 in the textbox, which is fine.However, any number with a space in it causes the validator to fail, which is not fine. Is there any way to make the CompareValidator work properly with non-US formatted numbers?
C# - Extend AuthorizeAttribute And Check The User's Roles?
Feb 25, 2011I am busy writing my own custom attribute for my action method called MyAuthorizeAttribute, I am still busy writing the code, here is my partial code:
[AttributeUsage(AttributeTargets.Method, AllowMultiple = false)]
public class MyAuthorizeAttribute : AuthorizeAttribute
{
public new Role Roles;
public override void OnAuthorization(AuthorizationContext filterContext)
{
base.OnAuthorization(filterContext);
if (Roles != 0) // Did it this way to see what the value of Roles was
return;
// Here I am going to get a list of user roles
// I'm doing my own database calls
filterContext.Result = new HttpUnauthorizedResult();
}
}
Here is my Role enum:
public enum Role
{
Administrator = 1,
SuperAdministrator = 2
}
My action method:
[MyAuthorize(Roles = Role.Administrator|Role.SuperAdministrator)]
public ActionResult Create()
{
return View();
}
The reason why I did not use Roles = "Administrator,SuperAdministrator" was because the roles are hard-coded. I don't want to have a 100 places to change if the role name changes.
Given my method, when it gets to if (Roles != 0) then Roles total value is 3, how would I check to see if these 2 roles is in the list of user roles for a specific user?
Am I doing it correct here? If not how would I otherwise implement this? It doesn't have to be the way that I did it in.

How To Check Page Validation Error
Apr 4, 2010An 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.

View 4 RepliesWeb Forms :: Validation - Check Address Already In The Database?
Jan 27, 2011I 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?

Web Forms :: To Handle The Validation To Check The File Size?
Oct 26, 2010In 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?

VS 2005 Programatically Check If Validation Has Failed / How To Solve
Dec 9, 2010I 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?
Metadata And Validation - Range Check Skipped Completely
Mar 7, 2010I 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?

Validation Check Which Prompt As Soon As User Leave The Control?
Jun 18, 2010We 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.

This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack.
