MVC :: Validate The User Have Entered Only Numbers For A Field On Server Side ?

Feb 4, 2010

If i use DataAnnotations on my Model and my model have something like this:

[Code]....

and in my View, i have a textbox WITHOUT client side validation. If the user enter non-numbers caracters in this field, i would like to validate on the server side that the user have entered non-authorized caracters and message him back on that. But since that my Model's Days property is a INT, the ModelBinder can't parse the string in the int property and generate an error in the ModelState with no message at all. And if the user doesnt enter anything on this field, the ModelBinder also try to put an empty string in a int property and generate an error in the ModelState with the message "a value is required". This is not the message that is written within the DataAnnotation. I have no control on the message that is generated.

So my question is:how can i valide the users input for int properties (or DateTime, etc...) and if the user enter a bad value i can put in the ValidationSummary something like this: "You can't only enter a numeric value for Days".

Web Forms :: Disable Required Field Validator At Server Side?

Feb 10, 2010

my question is very simple. I had read through many post include this: http://blog.anasghanem.com/post/How-to-get-the-readonly-textbox-value-on-the-server-.aspxI have a calender extender and the date was target to a texbox. This textbox, i had set it to readonly and it is validate by a required field validator. so mean this texbox must have a value inside. my prob is, i bind the textbox to database and if data is NULL or empty i can't save it because the required field validator was validate textbox as empty value at cllient side. If i remove the required field validator everthing fine. But this is not i want. I have try to set the textbox to javascript onCopy,onPaste,onkeyup. but user also can delete and paste into the textbox.i have think to disable the requried field validtor at server side when data is inserted.

Javascript - User Control With Client + Server Side CustomValidation; Wrong Client Side Validator Is Picked

Nov 23, 2010

I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)

<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...

There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)

<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...

There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.

<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");

[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.

Web Forms :: How To Use Server Side Validation To Ensure Image Field Is Not Null

Aug 20, 2010

I'm having trouble accomplishing the above. Below is all the mark up and code. I'm not getting error messages, but the validate image function is not working (fileupload portion is working ok).

In my attempt below---not sure if it's the simplest or best validation approach anyway---the "UserId" parameter appears during rendering to be empty---but in most methods I have it successfully containing or referring to the logged-in user's identification.

Following is the control that refers to the image field (page = advertisement.aspx):

<asp:Image ID="Image" runat="server" ImageUrl ='<%#Eval("UserId","Image.aspx?UserId={0}") %>'

Following is the successful code behind for the page image.aspx referred to above (page = image.aspx.vb):

Caching A Server Side User Control?

Sep 8, 2010

My asp.net app is heavily using user controls and is high load; my concern is that loading user controls for every request (Page.LoadControl(controlPath)) is sub-optimal at best. I was thinking of caching an instance of loaded user control in HttpRuntime, but I don't know how's it going to behave when multiple connections (threads) will try to fetch it from the cache and modify properties - I guess trouble is waiting there. Any good way to optimize user control loading?

Again, I am talking about caching user control, not it's html output (which it makes no sense caching as it's [html output] going to be different every time you use it)

Use Server Side Validation That Asks The User Question?

Jun 15, 2010

I'm trying to use validation (probably utilising the CustomValidator in ASP.NET 2.0) that checks whether a user entered order id already exists in a database, then, if it does exist, display a prompt for the user to ask whether they want to overwrite the order or enter a different order number. I'm not sure how to do this. I know I can use client side validation for the user prompt, and server side validation to check the order number against the database, but I'm not sure how to put the two things together i.e. check the database then, if the order exists, ask the user whether they want to overwrite the current order or go back and enter a new order id.

Using .NET To Always Run Some Server Side Code When A User Leaves A Page?

Jan 13, 2011

I was wondering if there is any way to always run some server side code when a user leaves a page in ASP.NET. The page Unload event is no good because that doesn't get called if someone clicks on a link. Ideally I'd also like the code to run even if the user closes the browser.
