ASP. NET MVC5 add verification (4), asp. netmvc5 Sometimes we need to add verification to our website. This section demonstrates how to use ASP. NET MVC5 to add verification. 1. Add verification in the Model class. The Code is as follows: Public class Movie {public int ID {get; set;} [StringLength (60, MinimumLength = 3, ErrorMessage = "the topic length must be 3 to 60 characters")] public string Title {get; set;} [Display (Name = "Release Date")] [DataType (DataType. date)] [DisplayFormat (

DataGrid is an important control in Asp. NET. It is often made into a paginated and sortable DataGrid, and sometimes the selection function needs to be added. These are frequently used methods, which are actually relatively simple.Design Concept: For convenience, we connect to the Orders table of the NorthWind database of SQL Server 2000 to obtain the data view of this table from the database. Use the DataGrid SortCommand event to sort data. Add the CheckBox control to a template column for sele

Text = Convert.todatetime (e.item.cell[0]. Text). ToShortDateString ();3. Use the String class to convert the date display format: String.Format ("Yyyy-mm-dd", yourdatetime);4. Convert date display format with convert method: Convert.todatetime ("2005-8-23"). ToString ("YyMMdd", System.Globalization.DateTim

addition to using the off-the-shelf DataType formatting features, you can also specify dataformatstring values explicitly. The following code shows the ReleaseDate property uses a formatted string, which you can use to not display The time portion of the ReleaseDate date:[DisplayFormat (dataformatstring = "{0:d}")]public DateTime releasedate {get; set;}The following code displays the price as a currency

try to format and display data in the engine. You can use the RegularExpression feature to verify the data format. In addition to the existing ype formatting feature, you can also specify the DataFormatString value. The following code shows how to format a string using the ReleaseDate attribute. You can use it to not display the time part of the ReleaseDate Date: [DisplayFormat(DataFormatString = "{0:d}")]

set the DataFormatString property of the UnitPrice bound column to {0:C} and its HTMLEncode property to False. Figure 7: Setting the DataFormatString and HTMLEncode properties of the UnitPrice bound column With this change, a row in a non edited state is formatted as a currency; however, the currently edited line still appears to have no currency symbol and retains four decimal places. Figure 8: Now

Sometimes we need to add validation to our site, and in this section we demonstrate how to add validation using asp.net MVC5. 1. In the model class to add validation, the code is as follows: public class Movie {public int ID {get; set;} [Stringlength (60,minimumlength=3,errormessage= "Subject length must be 3 to 60 characters")] public string Title {get; set;} [Display (name= "Release Date")] [DataType (datatype.date)] [DisplayFormat (

; Open the Movie.cs file, noting that the System.Web namespace does not contain System.ComponentModel.DataAnnotations. DataAnnotations provides a set of built-in critical properties that you can apply to classes, properties. (DataAnnotations also contains a datatype attribute to help format the method to validate) nbsp; update movie classes to take advantage of the built-in required, Stringlength, RegularExpression and range validation properties. Use the following code as an example to apply a
