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; } }}
I have a table "RANGES" with the following columns
LowRange as int HighRange as int with the data similar to below select * from Ranges LowRange HighRange 1 100 101 200 201 300 . . . 901 1000
And another table "infoDetails" with the following columns
Range as INT amount as money with the data similar to below select * from infoDetails Range Amount 23 34.00 235 44.00 345 34.00 678 100.00 555 100.00 530 100.00 510 100.00 I need one report with the following format without cursor. LowRange HighRange Count Amount 1 100 1 34.00 101 200 0 0.00 . . 501 600 3 300.00 601 700 1 100.00
We are writing a feature that allows an administrator to block/allow ranges of ip addresses.
Is this easy enough to do with c#?
I was thinking of looking at each number [here].[here].[here].[here] and then mathing it with the ranges and just seeing if each number was between the two?
If we let users input a couple of ip ranges, e.g., 172.16.11.5 - 100, how could I write a fucntion to check if a IP (172.16.11.50) falls in the ranges?
Is there any existing library in .NET to leverage?
In ASP.Net textbox, How I can restrict the user to enter maxlength. I should show message in label or message box, if user exceeding the maximum length. I am using C# as code behind.

this room is already booked from 1st march to 10th march.
1. The plus sign '+' is skipped (doesn't appear) when I submit the content.2. When I copy -for example- a code from Visual Studio and paste it in the editor, the spaces are skipped.I want the code to be displayed exactly as it is in Visual Studio.
I have asp.net form having 4 check boxes. not check box list. these 4 check boxes having the ValidationGroup property with same name say "chkValied". I have added Custom Validator there. now want to check at least on check box should be check out of these.

I have a ListView InsertItemTemplate where there is field (Date) using the AJAX Library CalendarExtender. I want to add some validation to this field, whereby they can't add a date that is later than today. So I have added a RangeValidator and tried to set its MaximumValue to DateTime.Now on Page Load. Unfortuantely it isn't working.
I want to put validation in a Textbox, that the numbers entered inside textbox should be between 1 to -1 only i.e., (-1, -0.1, -0.2, -0.3, -0.4, -0.5, -0.6, -0.7 ....... 1 )I tried below code but "RangeValidator" is not working as per requirement:
HTML:
<asp:RangeValidator ID="RangeValidator1" runat="server" MaximumValue="1" MinimumValue="-1" Text="value between 1 to -1" ErrorMessage="value between 1 to -1" ControlToValidate="TxtY" ValidationGroup="usrvalid"></asp:RangeValidator> <asp:TextBox ID="TxtY" Text='<%#Eval("Y") %>' runat="server" Width="30%"></asp:TextBox> <cc1:FilteredTextBoxExtender ID="FilteredTextBoxExtender5" TargetControlID="TxtY" FilterType="Custom" ValidChars="-01234567890." runat="server"></cc1:FilteredTextBoxExtender>
I would like to extend the HtmlHelper by using metadata (similar to DataAnnotaions metadata). Specifically I want to be able to add a 'Title' attribute to html controls that will then appear as a tooltip on the control. I would like to keep the tooltip text with my model, for example by adding 'Tiltle' metadata to the model as follows:
[DisplayName("User Id")] [Title("Enter your 10 digit user id")] property UserId { get; set; }
So the questions are:
1. How do I add metadata (such as 'Title') to my model?
2. How do I access this metadata in my HtmlHelper extension method?
