In this post we are going to learn the pagination in the data grid where we will have options to select the number of records to be displayed per page in the data grid. you can select the count from the record per page combobox and based on that you can see the records. I will add the four buttons which is used for show the first page, previous page, next page and last page. Below is DataGrid control code:  <DataGrid Grid.Row="1" ItemsSource="{Binding EmployeeCollection}"                    AutoGenerateColumns="False" CanUserAddRows="False">             <DataGrid.Columns>                 <DataGridTextColumn Header="ID" Binding="{Binding ID}"/>                 <DataGridTextColumn Header="Name" Binding="{Binding Name}"/>                 <DataGridTextColumn Header="Age" Binding="{Binding Age}"/>                 <DataGridTextColumn Header="Gender"

  IoC Container IoC Container is a framework for implementing automatic dependency injection . before I explain IoC Container first lets know what is  dependency injection Dependency Injection It is a design pattern used to implement IoC. It allows the creation of dependent objects outside of a class and provides those objects to a class through different ways.  The Dependency Injection pattern involves three things which are client, service and the injector so, there will be  three  types of classes  involves in this process . Client Class : The client class is a class which depends on the service class. Service Class : The service class is a class that provides service to the client class. Injector Class : The injector class injects the service class object into the client class. The injector class injects dependencies in three ways: through a constructor, or through a property, or through a method. so, there are three types of Dependency Injection which are: Constructor Injection

Step 1: Right click on project Step 2: Click on Add and select New Item Step 3: Search for Custom Control Step 4: Select Custom Control(WPF) Step 5: Write ExpandableTextBox in Name and click on Add It will create one class with the Name ExpandableTextBox with following code: namespace CustomControl.Controls { public class ExpandableTextBox : Control { static ExpandableTextBox() { DefaultStyleKeyProperty.OverrideMetadata(typeof(ExpandableTextBox), new FrameworkPropertyMetadata(typeof(ExpandableTextBox))); } } } It will also create a folder called Themes inside this folder it will create ResourceDictionary with the Name Generic with folowing code: Generic.xaml <ResourceDictionary xmlns:local="clr-namespace:Wpf" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"> <Style TargetType="{x:Type local:ExpandableTextBox

In this post i will explain how to Import/Export data of DataGrid from/to CSV file in wpf using MVVM To Import CSV to DataGrid i have created method called LoadCSV() which will load CSV data and update the DataGrid  private void LoadCSV()         {             LstEmployees.AddRange(File.ReadAllLines("csvFilePath")                                          .Skip(1)                                          .Select(v => CsvToEmployees(v))                                          .ToList());         }          In LoadCSV() method i am first reading the CSV using File clas ReadAllLines() method After that i am skip the first line becuase in first line we used to have Header for CSV file And then i am calling CsvToEmployees() which take a single line and split the text by comma and then convert it to Employees. After converting All text to Employees list i am adding the list to ObservableCollection which is Binded with DataGrid         Employees CsvToEmployees(string c
