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.

View 2 RepliesI 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.
