Web Forms :: How To User Validation Controls With FileUploader

Dec 15, 2010

I have a fileUplaoder control on my form, The file has been uploaded when the user click the button. I wanted to associate a Custom Validator (Or some other validator), that will check

1. File Type (To exclude .exe etc)

2. File size (To restrict user not to upload a file >5MB)

If the above 02 conditions are violated it will stop the user to submit the form and will show the appropriate error messages on the validation summary. (Like the file is larger then the allower size etc etc)

I wanted to use validation summary for this purpose as I am already displaying all validation messages for all controls on the validation summary

Jul 17, 2015

Article : Encrypt and Decrypt Username or Password stored in database

The whole thing works very well but my issue is, after entering and encrypted password how does the user then log into the database?

When a user types in his password, the typed in password will not match the ecnrypted value in the database.

So how do I decrypt what is in the database and compare with what the user typed in and then validate the user.

Web Forms :: FileUploader, Above Maximum Allowed Size Causes A "crash"/redirect?

Nov 5, 2010

I couldnt help but notice that if you have a FileUpload-control, and then try to upload a file thats bigger(in bytes) then the allowed maxiumsize, then the site crashes or some wierd "Connection problem"-page shows up, atleast for me in Firefox...

So my question is simply...is this just for me?..and if not, how do I fix this the best way?...cause the current "crash-page" aint a nice way of handeling the problem in my opinion...whould be much better to actually just show some custom-page that lets the user know that thier trying to upload a file thats way to big..

C# - Set Validation For All Controls In An User Control?

Nov 23, 2010

I am looking for the best way to set the validation group for all of the controls contained in a user control. Most of the controls in the control are created dynamically when the control is loaded. It has quite a few input fields and validators.

I would like to save time by setting the validation for all the controls and validators with some sort of function that could just loop through everything and set it.

It seems though that there is no consistent interface that includes validation group for all of the different controls that have the property.

Should I use reflection to check for Validation group, I know I can do this, but is there a better way?

We are using C# by the way.

EDIT: I put the answer down below for anyone who wants the code.

Web Forms :: Validating Input In A Custom User Control Using Jquery Validation Plugin?

Jun 18, 2010

I have a custom user control with some input fields and a submit button. I need to validate the fields using the jquery validation plugin when the submit button is clicked. (The function of the submit button is to create another custom control which displays the data entered in the above mentioned control)

Bt as far as I knw, validation plugin works only with form validation ryt? And my custom control does not contain a form tag as I am using master pages. The custom control is present in one of the content pages and the master page already contains a form tag with a runat=server attribute. And I guess one page can contain only a single form tag with runat=server attrib ryt?

So how do I get it to work?

Web Forms :: Displaying A Summary Of Validation Errors As User Moves Between Views In MultiView?

Feb 3, 2011

I am using a MultiView control inside a FormView to break my form into more manageable sections for the end-user. I am trying to make it so that each time the Next button is clicked, the entire form is validated and a list of the fields that have not yet been completed show up in the Validation Summary.

I would like my users to be able to continue through the MultiView 'wizard' even if they haven't completed all the fields -- they should be able to come back to them later. But I would like the ValidationSummary to display the fields they've not completed that are required as a reminder of what to come back to if possible.

I've tried playing around with Page.IsValid with no success.

[Code]....

The code-behind for the Next button is as follows:

Web Forms :: Activate ChecKBox Validation When Clicking Button In Created User Wizard Control?

Oct 26, 2010

I have a checkbox on my page that must be ticked and to validate it I am using a custom method as below. The problem is that I now put the checkbox and method within a Create User Wizard custom tempalte and when I submit the form it does not activate the validation check. If I put a normal button on the page outside the tempalte it works. Not sure If I a missing something. Perhaps I can activate it in Created User Event handler in code behind. All Button in my create user Event.

<asp:Button
ID="StepNextButton"
runat="server"
CommandName="MoveNext"
OnClientClick="ShowMP();"
align="middle"
CausesValidation="True"
Text="Submit
my Profile"
/>

aspx
<asp:CheckBox ID="Terms" runat="server" />
<asp:CustomValidator ID="valTandCs" ClientValidationFunction="ValidateTandCs" runat="server" ErrorMessage="Please accept Terms and Conditions before submitting."></asp:CustomValidator>
Javascript
<script language="javascript" type="text/javascript">
function ValidateTandCs(source, args)
{
args.IsValid = document.getElementById('<%= Terms.ClientID %>').checked;

How To Extend Server-side Validation Controls To Raise An Event If Validation Fails

Feb 23, 2010

I 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?

Is It Possible To Use Validation Controls When I Need To Modify HTML When Validation Fails

Mar 16, 2011

Let's say that I have the following HTML for a text box on an ASP.NET page:

<div class="myClass">
<asp:TextBox ID="txtMyTextBox" runat="server"></asp:TextBox>
</div>

It is easy enough to add a required field validator to this page like this.

<asp:RequiredFieldValidator ID="valMyTextBox" runat="server" ControlToValidate="txtMyTextBox" ErrorMessage="My Text Box is required."></asp:RequiredFieldValidator>

But I need to modify the HTML slightly if this text box fails validation. I need to add a CSS class to the DIV. So if the user leaves this field blank I need the HTML to look like this:

<div class="myClass error">
<asp:TextBox ID="txtMyTextBox" runat="server"></asp:TextBox>
</div>

Is this possible? I can't figure out if there is a way to write code behind that only fires if this particular validator control fails validation or something. I know I can write code that runs when the entire page is not valid. But I just want this code to run when this validator returns invalid. Hope this makes sense.
