Metadata And Validation - Range Check Skipped Completely

Mar 7, 2010

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; } }}

Regex Validation On A Text Box Locks-up Text Box On Postback?

Nov 10, 2010

I have a web application (done in ASP/C#) that has regex validation on a text box. Initially the regex works perfectly fine. But then I also provide a button click event (clear) that allows the user the clear text box and change their input for a new query. At this point (page post back) the regex takes control and maintains control of the text box so a new query can't be run. Can anyone tell me what to do so that the regex doesn't fire on page postback and allows new input for validation?

VS 2008 - Reading Contents Of A Text File Into Text Box On Form

Jul 13, 2011

I'm trying to read the contents of a text file into a text box on my form. When I run the following code, nothing happens.

VB.NET Code:
Protected Sub lbLogs_SelectedIndexChanged(ByVal sender As Object,
ByVal e As EventArgs) Handles lbLogs.SelectedIndexChanged       
For Each li As ListItem In lbLogs.Items           
If li.Selected Then                Using sw As New StreamReader(li.Value)                   
txtLog.Text = sw.ReadToEnd                     sw.Close()                End Using            End If        Next    End Sub

I populate the ListBox with ListItems and each ListItem's Value property holds the full path to the file. But, I removed all of that and just put txtLog.Text = "test" inside of the "is selected" block.

VS 2008 - Server Text Field To Text Box

Apr 11, 2014

I have an old database that still contains depreciated Text fields. I need to pull from these fields and display the results. You would think this should be easy... First my select statement caused a problem:

Code:
SELECT DISTINCT ..., CustomerInstructions, ... FROM Orders
where CustomerInstructions is a Text field.

The error I get: "The text data type cannot be selected as DISTINCT because it is not comparable." A quick search shows I can cast the text field as a varchar(max).

Code:
SELECT DISTINCT ..., CAST(CustomerInstructions AS VARCHAR(MAX)), ... FROM Orders

Now I get an error while trying to load the instructions into a text box: "Specified argument was out of the range of valid values. Parameter name: index"

Not sure what the problem is here. I have text and a text box. What's with the "out of range" crap?

VS 2008 Disable Submit Button Onclick With Validation

Oct 19, 2010

I have a form that occassionally submits more than once per user. I am assuming the problem is that the user gets impatient and clicks submit multiple times. I have a bunch of asp validation controls on the page. There is multiple validation groups, the submit button belongs to the "main" group. How do I validate the "main" group, then if the page is valid, disable the button and submit it? I tried adding this.disabled=true; but that just disables it and doesnt submit or anything.

VS 2008 Using Clientside Js In Onclick Alongside Validation Controls?

Aug 15, 2010

I'm currently using Validation controls to validate a form. I tried adding a separate onclientclick javascript method to do some extra validation but it now appears to only run this and not continue on to run through the Validation controls. The extra javascript method is returning true, so I'm not sure if the onclientclick is clobbering the scripts from the Validation controls. Can anyone explain what I've done wrong?

Suppress Specific CSS 2.0 Validation Errors In Visual Studio 2008?

Feb 5, 2010

A typical CSS property that I use often is overflow-x and overflow-y. Sometimes I use CSS 2.1 or later properties or selectors. These (correctly) raise a validation error: Validation (CSS 2.0): 'overflow-y' is not a known CSS property name.For years I ignored this, but it kinda feels wrong. It's possible to switch off warning in C# and other languages for a particular line, block, file or project. Is something similar possible for CSS (or HTML) errors or warnings? Instead of switching it all off, I prefer a more granular solution.
