Bind Sqlite Data To WPF Datagrid And Perform CRUD Actions

Updated on May 19, 2026

Overview

This repository demonstrates a comprehensive example of how to bind SQLite database data to a WPF DataGrid and efficiently perform CRUD (Create, Read, Update, Delete) operations. The sample showcases an Employee Management system where users can view, add, edit, and delete employee records stored in a local SQLite database.

What is SQLite?

SQLite is a lightweight, file-based relational database that does not require a separate database server. It stores all data in a single file (SQLiteData.db) on the local machine and is ideal for desktop applications. SQLite provides a complete SQL database engine that can handle data storage, retrieval, and manipulation efficiently.

How SQLite is Used in This Application

Database Setup

The application creates an SQLite database connection using SQLiteAsyncConnection which allows asynchronous database operations:

public class SQLiteDatabase
{
    readonly SQLiteAsyncConnection _database;
    public const string DatabaseFilename = "SQLiteData.db";

    public static string DatabasePath =>
        Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), DatabaseFilename);

    public SQLiteDatabase()
    {
        _database = new SQLiteAsyncConnection(DatabasePath, Flags);
        _database.CreateTableAsync<Employee>();
    }
}

The database file is stored in the LocalApplicationData folder and is created automatically on first run. The Employee table is created with the necessary schema.

Reading Data

When the application starts, it loads all employee records from the SQLite database and displays them in the WPF DataGrid:

private async void OnWindowActivated(object? sender, EventArgs e)
{
    sfDataGrid.ItemsSource = await App.Database.GetEmployeesAsync();
}

The GetEmployeesAsync() method retrieves all records from the SQLite database:

public async Task<List<Employee>> GetEmployeesAsync()
{
    return await _database.Table<Employee>().ToListAsync();
}

WPF DataGrid Binding

The application uses Syncfusion's SfDataGrid control to display and manage employee data. The DataGrid is configured with the following features:

<syncfusion:SfDataGrid x:Name="sfDataGrid"
                       AutoGenerateColumns="True"
                       AllowDraggingColumns="True"
                       AllowResizingColumns="True"
                       AllowSorting="True"
                       SelectionMode="Single">
    <!-- Context Menu for CRUD operations -->
</syncfusion:SfDataGrid>

Key Features:

AutoGenerateColumns: Automatically creates columns for all properties of the Employee class
AllowSorting: Users can sort data by clicking on column headers
AllowResizingColumns: Columns can be resized by dragging
SelectionMode: Users can select individual employee records for editing or deletion
RecordContextMenu: Right-click context menu provides quick access to CRUD operations

Performing CRUD Actions

CREATE - Adding New Employee Records

Users can add new employee records through the Add menu option:

private void OnAddMenuClick(object sender, RoutedEventArgs e)
{
    AddOrEditWindow addWindow = new AddOrEditWindow();
    addWindow.Title = "Add Record";
    addWindow.Show();
}

When the save button is clicked in the AddOrEditWindow, a new employee record is inserted into the SQLite database:

 private async void OnSaveClick(object sender, RoutedEventArgs e)
{
    bool isEdit = true;
    if (SelectedRecord == null)
    {
        isEdit = false;
        SelectedRecord = new Employee();
    }

    double employeeID;
    if (double.TryParse(this.employeeIDTextBox.Text, out employeeID))
        SelectedRecord.EmployeeID = employeeID;
    SelectedRecord.Name = this.employeeNameTextBox.Text;
    SelectedRecord.EMail = this.EmployeeMailTextBox.Text;
    SelectedRecord.Gender = this.GenderComboBox.SelectedItem.ToString();
    SelectedRecord.BirthDate = this.EmployeeBirthDatePicker.SelectedDate;
    SelectedRecord.Location = this.EmployeeLocationTextBox.Text;

    if (isEdit)
        await App.Database.UpdateEmployeeAsync(SelectedRecord);
    else
        await App.Database.AddEmployeeAsync(SelectedRecord);

    this.Close();
}

The AddEmployeeAsync() method inserts the record:

public async Task<int> AddEmployeeAsync(Employee employee)
{
    return await _database.InsertAsync(employee);
}

READ - Displaying Data in DataGrid

The DataGrid continuously displays the employee data stored in SQLite. Users can:

Sort data by clicking column headers
Resize columns to view different fields
Select individual records for viewing details
Search and filter data through the DataGrid's built-in features

UPDATE - Editing Existing Records

Users can edit employee records by selecting a record and clicking the Edit option:

private void OnEditMenuClick(object sender, RoutedEventArgs e)
{
    AddOrEditWindow editWindow = new AddOrEditWindow();
    editWindow.DataContext = (Employee)sfDataGrid.SelectedItem;
    editWindow.Title = "Edit Record";
    editWindow.SelectedRecord = (Employee)sfDataGrid.SelectedItem;
    editWindow.Show();
}

The selected employee record is passed to the edit window where users can modify the data and save:

if (isEdit)
    await App.Database.UpdateEmployeeAsync(SelectedRecord);

The UpdateEmployeeAsync() method handles the update operation:

public Task<int> UpdateEmployeeAsync(Employee employee)
{
    if (employee.EmployeeID != 0)
        return _database.UpdateAsync(employee);
    else
        return _database.InsertAsync(employee);
}

DELETE - Removing Records

Users can delete employee records by selecting a record and clicking the Delete option:

private void OnDeleteMenuClick(object sender, RoutedEventArgs e)
{
    DeleteWindow deleteWindow = new DeleteWindow();
    deleteWindow.SelectedRecord = (Employee)sfDataGrid.SelectedItem;
    deleteWindow.Show();
}

When confirmed, the record is deleted from the SQLite database:

private async void OnYesClick(object sender, RoutedEventArgs e)
{
    await App.Database.DeleteEmployeeAsync(this.SelectedRecord);
    this.Close();
}

The DeleteEmployeeAsync() method removes the record:

public Task<int> DeleteEmployeeAsync(Employee employee)
{
    return _database.DeleteAsync(employee);
}
