I am having a strange issue.
I have a file upload control and a custom validator to check the file size.
When the file size is small and when I hit upload button it hits the breakpoint on the custom validator BUT strangely when the file size is big it does NOT hit the custom validator and see the following IE error.
Internet Explorer cannot display the webpage

View 1 RepliesI am running the code below in a .net 2.0 content page.There are no containers such as wizard etc. When I click on the submission button for debugging purposes I get 'Nothing'. why I can't access the 'controlToValidate'?
Protected Sub validateCharacter(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs)
If Page.IsPostBack Then

I have 2 custom validator controls on my page but for some strange reason the Custom Validator for FileUpload control works and the custom validator for TextBox control does not work. Here is the aspx code:
<asp:FileUpload ID="_fileCv" runat="server" Width="500px" /><br />
<asp:RequiredFieldValidator ID="_rfvFileCv" runat="server" ErrorMessage="Resume; " ControlToValidate="_fileCv" SetFocusOnError="True" ValidationGroup="APPLY">
<img src="images/mandatory.gif" alt="Required" /></asp:RequiredFieldValidator
<asp:CustomValidator ID="CustomValidator1" runat="server" ControlToValidate="_fileCv"
ErrorMessage="Max file size for documents is 4MB." OnServerValidate="CustomValidator1_ServerValidate" ValidationGroup="APPLY"></asp:CustomValidator>
<asp:TextBox ID="_txtHealthComments" runat="server" TextMode="MultiLine" Rows="5" Width="500" />
<asp:CustomValidator ID="CustomValidator2" runat="server" ControlToValidate="_txtHealthComments"
ErrorMessage="Kindly enter health Comments ." OnServerValidate="CustomValidator2_ValidateHealth" ValidationGroup="APPLY"></asp:CustomValidator>
Here is the code behind:
protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args) {
if (_fileCv.FileBytes.Length > 4194304) {
args.IsValid = false;
} else { args.IsValid = true; } }
protected void CustomValidator2_ValidateHealth(object source, ServerValidateEventArgs args) {
if (_rdoHealth.SelectedValue == "1" && _txtHealthComments.Text == "") {
args.IsValid = false; } else { args.IsValid = true; } }
I created my custom validator in one project, something like that:

he composite control in another project. I added a reference of the custom validator project to the composite control project. I have a textbox in a composite control and I would like to validate this textbox by the composite control I created. But how can I do that? How can I create the custom validator instance that is linked to the custom validator I created?
I'm trying to create a custom control that has a dropdown list and a required field validator in it.I've got as a far as being able to set the error message if the control fails to validate, but I can't actually get it to validate, not can I figure out how to call a .Validate method server side. This is driving me nuts!
To create my control, I followed the article here I ran the text box example through, and I can get that to validate without any problems, so I then went through and created a new set of class files relating to a drop down list.Anyone got any thoughts, or hints as to what might be wrong, or where I should start looking?
Is it necessary to give Control to Validate control in Custom Validator?
If yes then why this will happen?
I am trying to set the width property of a custom control validator but it is not happening at all. The width of the validator control popup is constantly 100% width (the width="200px" below has NO effect at all)
here is my code:
[code].....
there is a sample code for creating a custom textbox control with built in validation posted here Building ASP.NET TextBox with Integrated Validation And Switchable Input Modes. Inside the code there is a call to Controls.Add(validator) which adds the asp.net validator control to the textbox. when the textbox is used on the page, the validator is rendered to the page although the validator is added to the textbox and not to the page!
View 1 RepliesI have a validator callout extender that works, it shows the callout box. But, it does a postback. It didn't do a post back the first time I clicked the button but it did for subsequent times. I read on the AJAX site that a custom validator must be used with this for it to work. I'm currently using this with a required field and regular expression validator. It works, the callout appears, but it doesn't work every time with out the post back.I posted this to see if there is a way to get this to work with a required field and regular expression validator, with out using a custom validator. I'm using the newest release of the toolkit, so I thought the documentation may be old, since the callout is appearing.

I've been trying to get a custom validator component working that ensures at least one checkbox from a checkboxlist has been checked. I've been used some code I found on dotnetjunkies.com but the client-side validation didn't work. I've been attempting to modify it to get the client-side javascript validation to work with no luck. Basically, I compile the below code into a DLL and add it to my bin folder.

I have a custom validator, which I have set a property for, and I can access this validator from my MVC controller method. However, when I run the code, I am not seeing the error message on the page. My code in the controller method looks like this:
If (!bool)
{
this.view.customValidator.IsValid = false;
this.view.customValidator.Visible = true;
}
I am using Customvalidator control . I am giving client side validation function in it. On running it is giving error as: ValidationStream is not defined.
Following is the code:
<asp:CustomValidator ID="CustomValidator6" runat="server" ClientValidationFunction="validateDriveDate"
<asp:TextBox ID="txtMobile" runat="server" MaxLength="11"></asp:TextBox>
<ajaxToolkit:FilteredTextBoxExtender ID="fteMobile" runat="server" TargetControlID="txtMobile"
FilterType="Numbers" />

View 3 RepliesI am using C# for ASP .NET 2.0. On my web form I have a TextBox that I want to let the end-user type inside of. The rules are as such: They should only be allowed to type numbers and a decimal. No negative numbers allowed. The number has to range from 0.00 to 24.00 - for hours - and can only allow for quarter hours - example: 0.00, 0.25, 0.50, 0.75, 1.00, 1.25, etc. Do I need a custom validator for this? If so, I do I check to see that the number is valid?
View 5 RepliesI have the current block of code inside an OnPreRender method of a validator that is inheriting from BaseValidator. If I have one instance of the validator this works fine, but if there are multiple instances the javascript flakes out. As it stands the acutal evaluation function has to be rendered on a per instance basis. I know it's kind of a drop in the bucket, but I'd like to register the block below just once instead of giving each instance a unique key to register with.

I've read quite a few posts here on this issue, but none of the solutions seem to be working for me.
I have a list box and a custom validator that is using a client side function to validate.
There is also a required field validator on the page.
Here's the markup:
[Code]....
So in any case, i should have an error message on the page and it should not post back, correct?

I am currently using a maskedEditValidator to do some validation checks in a field, everything works great until I attempt to insert a maximium value. My current maskededitvalidator looks like this:
[Code]....
When I add the maximium value into it, it pops up on the details view and will not go away thus not allowing for the new record to be entered. From what I have seen through various other post is that this is a know bug in the maskededitvalidator, and that if I want to do this to do it in a custom validator. My problem is I have no clue as to how to do this in a custom validator.
I am using a PasswordRecovery Control and have changed one of the validators to a custom Validator, however, OnServerValidate neer seems to get called.
Can someone tell me how to get the OnServerValidate to work correctly?
