.NET GENES

Good morning! Here's the VB.NET version of this post WPF CRUD with DataGrid and Entity Framework C# . The steps to accomplish basing from the C# post are: a. Run the create table script assuming that you haven't created the Students table. b. Create a VB.NET WPF project. c. Replace the XAML markup of the window control. Once done, the scripts for the repository class and window code-behind are as follows: Repository Class Public Class StudentRepository Private studentContext As StudentEntities = Nothing Public Sub New () studentContext = New StudentEntities() End Sub Public Function GetStudent ( ByVal id As Integer ) As Student Return studentContext.Students.Find(id) End Function Public Function GetAll () As List( Of Student) Return studentContext.Students.ToList() End Function Public Sub AddStudent ( ByVal student As Student) If student IsNot Nothing Then ...

Good evening! Here's a simple WPF CRUD(Create/Update/Delete) application using DataGrid and Entity Framework. This doesn't involve the MVVM pattern and input validation. Maybe if I have time, in the future I'll post an MVVM equivalent post ( Update: I already have additional examples using RepoDB ORM and MVVM pattern in both C# and VB.NET at the end of this article ). So to proceed, execute the SQL script below and make sure to replace the database name with an existing one. USE [your_database] GO /****** Object: Table [dbo].[Students] Script Date: 3/31/2018 11:24:23 PM ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[Students]( [ID] [ int ] IDENTITY ( 1 , 1 ) NOT NULL , [Name] [ varchar ]( 50 ) NULL , [Age] [ int ] NULL , [Address] [ varchar ]( 50 ) NULL , [Contact] [ varchar ]( 50 ) NULL , CONSTRAINT [PK_Students] PRIMARY KEY CLUSTERED ( [ID] ASC ) WITH (PAD_INDEX = OFF , STATISTICS_N...

Hi, I was asked by a developer on how to fix the arrow which appears at the bottom of the calendar dropdown and not below the textbox. This issue was raised in my previous post Bootstrap DatePicker Control in ASP.NET Webforms . The solution is to reference the bootstrap-datepicker.css instead of bootstrap-datepicker3.standalone.css <link rel= "stylesheet" href= "https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.6.1/css/bootstrap-datepicker.css" /> <script type= "text/javascript" src= "https://cdnjs.cloudflare.com/ajax/libs/jquery/1.11.1/jquery.min.js" ></script> <script type= "text/javascript" src= "Scripts/bootstrap.min.js" ></script> <script type= "text/javascript" src= "https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.6.1/js/bootstrap-datepicker.min.js" ></script> <script type= "text/javascript" > Output ...

Good morning! In the event that you need to replace your queries using Union such as below: Use DBJersonsHW go SELECT DISTINCT [EmpName] AS [EmployeeName], EmpAddress As [Address] FROM tblEmployeesMain UNION SELECT DISTINCT [EmpName] AS [EmployeeName], EmpAddress As [Address] FROM tblEmployeesMetro ORDER BY [EmpName]; The alternative for that is to use Full Outer Join as presented below: Use DBJersonsHW go SELECT Distinct Coalesce(tblEmployeesMain.EmpName, tblEmployeesMetro.EmpName) AS EmployeeName, Coalesce(tblEmployeesMain.EmpAddress, tblEmployeesMetro.Address) AS Address, FROM tblEmployeesMain FULL Outer JOIN tblEmployeesMetro on tblEmployeesMain.EmpName = tblEmployeesMetro.EmpName order by EmpName Cheers! :-)
