WPF Search from ListView

In DAL use code like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

//Search Customer from listview public List<CustomerInfo> SearchCustomer(string searchValue) { dataContextObj = new JSMSEntities(); List<CustomerInfo> customerInfoList = new List<CustomerInfo>(); foreach (var p in (from c in dataContextObj.tbl_Customer where c.CustomerName.Contains(searchValue) || c.CustomerMobile.Contains(searchValue) select c).Distinct()) { CustomerInfo _customerInfoObj = new CustomerInfo(); _customerInfoObj.Id = p.ID; _customerInfoObj.CustomerName = p.CustomerName; _customerInfoObj.CustomerAddress = p.CustomerAddress; _customerInfoObj.CustomerPhone = p.CustomerPhone; _customerInfoObj.CustomerMobile = p.CustomerMobile; _customerInfoObj.CustomerFax = p.CustomerFax; _customerInfoObj.CustomerEmail = p.CustomerEmail; _customerInfoObj.CustomerNote = p.CustomerNote; customerInfoList.Add(_customerInfoObj); } return customerInfoList; }

In BLL use code like this:

1 2 3 4 5

//BLL Search customer public List<CustomerInfo> SearchCustomer(string searchValue) { return customerInfoGetwayObj.SearchCustomer(searchValue); }

In xaml.cs file use code like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

//Search Customer private void txtCustomerSearch_TextChanged(object sender, TextChangedEventArgs e) { _customerInfoList = new List<CustomerInfo>(); _customerInfoList = _customerInfManagerObj.SearchCustomer(txtCustomerSearch.Text); CustomerInfoListView.Items.Clear(); if (_customerInfoList.Count > 0) { foreach (var item in _customerInfoList) { CustomerInfoListView.Items.Add(item); } } }

WPF ListView Data Display

In DAL write code like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

public List<SaleInfo> LoadAllSaleList() { dataContext = new JSMSEntities(); List<SaleInfo> saleList = new List<SaleInfo>(); foreach (var p in (from c in dataContext.tbl_Sale select new { c.SaleDateTime, c.InvoiceNumber, c.tbl_Customer.CustomerName, c.TotalAmount, c.TotalPay, c.TotalDue }).Distinct()) { SaleInfo allsaleObj = new SaleInfo(); allsaleObj.SaleDateTime = (DateTime)p.SaleDateTime; allsaleObj.InvoiceNumber = p.InvoiceNumber; allsaleObj.CustomerName = p.CustomerName; allsaleObj.TotalAmount = (int)p.TotalAmount; allsaleObj.TotalPay = (int)p.TotalPay; allsaleObj.TotalDue = (int)p.TotalDue; saleList.Add(allsaleObj); } return saleList; }

In BLL write code like this :

1 2 3 4

public List<SaleInfo> LoadAllSaleList() { return _saleGetwayObj.LoadAllSaleList(); }

In XAML add ListView like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

<ListView HorizontalAlignment="Left" Height="509" Margin="10,52,0,0" VerticalAlignment="Top" Width="624" x:Name="SaleListView"> <ListView.View> <GridView AllowsColumnReorder="True"> <GridViewColumn DisplayMemberBinding="{Binding Id}" Header="" Width="0"/> <GridViewColumn DisplayMemberBinding="{Binding SaleDateTime, StringFormat='yyyy-MM-dd'}" Header="Date" Width="120"/> <GridViewColumn DisplayMemberBinding="{Binding InvoiceNumber}" Header="Invoice" Width="120"/> <GridViewColumn DisplayMemberBinding="{Binding CustomerName}" Header="Name" Width="100"/> <GridViewColumn DisplayMemberBinding="{Binding TotalAmount}" Header="Price" Width="90"/> <GridViewColumn DisplayMemberBinding="{Binding TotalPay}" Header="Total Pay" Width="100"/> <GridViewColumn DisplayMemberBinding="{Binding TotalDue}" Header="Total Due" Width="90"/> </GridView> </ListView.View> </ListView>

In UI add reference of BLL and ENTITY, then write code like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Shapes; using BLL; using ENTITY; namespace JSMS.UI { /// <summary> /// Interaction logic for SaleReportUI.xaml /// </summary> public partial class SaleReportUI : Window { List<SaleInfo> _allSaleListObj = new List<SaleInfo>(); SaleManager _saleManagerObj = new SaleManager(); public SaleReportUI() { InitializeComponent(); LoadAllSaleList(); } private void LoadAllSaleList() { _allSaleListObj = new List<SaleInfo>(); _allSaleListObj = _saleManagerObj.LoadAllSaleList(); SaleListView.Items.Clear(); if (_allSaleListObj.Count > 0) { foreach (var item in _allSaleListObj) { SaleListView.Items.Add(item); } } } } }

WPF XAML Horizontal Menu

1 2 3 4 5 6 7 8 9 10 11 12 13 14

<Menu Height="26" Name="topMenu" VerticalAlignment="Top" Margin="0,0,0,-5" FontFamily="arial"> <MenuItem Header="File" Name="FileMenu"> <MenuItem Header="Shop Setting" Name="mnuShopSetting" Background="Transparent" Click="mnuShopSetting_Click" /> <Separator /> <MenuItem Header="Exit" Name="mnuExit" Click="mnuExit_Click"/> </MenuItem> <MenuItem Header="Supplier" Name="SupplierMenu"> <MenuItem x:Name="mnuNewSupplier" Header="New Supplier" Click="mnuNewSupplier_Click" /> <Separator /> <MenuItem Header="Supplier Status Report" /> </MenuItem> </MenuItem> </Menu>

WPF ListView StringFormat

In XAML follow string formating like this way:

1	<GridViewColumn DisplayMemberBinding="{Binding PurchaseDate, StringFormat='yyyy-MM-dd'}" Header="Date" Width="100"/>

C# WPF, Access Parent Window Method from Child Window

For access parent window method from child window, first make parent window method as PUBLIC, then follow below code for child window.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

//Declear ParentWindow as GlobalPreview SupplierDueListUI globalPrewindow; public SupplierDueCollectionUI(SupplierDueListUI prewindow) { InitializeComponent(); globalPrewindow = prewindow; // Initial prewindow } private void btnUpdatePayment_Click(object sender, RoutedEventArgs e) { PurchaseInfo purchaseInfoObj = new PurchaseInfo(); purchaseInfoObj.Id = this._purchaseInfoObj.Id; purchaseInfoObj.ProductId = this._purchaseInfoObj.ProductId; purchaseInfoObj.SupplierId = this._purchaseInfoObj.SupplierId; purchaseInfoObj.TotalDue = Convert.ToInt32(txtTotalDue.Text); purchaseInfoObj.TotalPay = Convert.ToInt32(txtTotalPay.Text); if (purchaseInfoObj.TotalDue <= 0) { purchaseInfoObj.IsFullPaid = true; } _purchaseManagerObj.UpdatePurchasePayment(purchaseInfoObj); globalPrewindow.LoadAllPurchaseDueBill(); //Load Parent window method MessageBox.Show("Successfully Updated", "Success!", MessageBoxButton.OK, MessageBoxImage.Information); this.Close(); }

C# Generate an Unique code

This method use DateTime Ticks for generate an Unique code.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

//Generate Unique code using DateTime static string uniqueCode() { string characters = "K13A56Z89I"; string time = DateTime.UtcNow.Ticks.ToString(); var code = ""; for (var i = 0; i < characters.Length; i += 2) { if ((i + 2) <= time.Length) { var number = int.Parse(time.Substring(i, 2)); if (number > characters.Length - 1) { var one = double.Parse(number.ToString().Substring(0, 1)); var two = double.Parse(number.ToString().Substring(1, 1)); code += characters[Convert.ToInt32(one)]; code += characters[Convert.ToInt32(two)]; } else code += characters[number]; } } return code; }

C# Entity, Load Data from Child window to Parent window

In child window create an event and use code like this:

1 2 3 4 5 6 7 8

//Send data to Parent form private void CustomerInfoListView_MouseDoubleClick(object sender, MouseButtonEventArgs e) { if (CustomerInfoListView.SelectedIndex > -1) { this.DialogResult = true; } }

Now in Parent window create a button event for show child window and get data. Use code like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

//Get data from child window and set it to parent window private void btnGet_Click(object sender, RoutedEventArgs e) { CustomerInfoUI customerUI = new CustomerInfoUI(); //Child window object if (customerUI.ShowDialog() == true) // Set condition for show child window and do some operation { CustomerInfo customerObj = new CustomerInfo(); //Child window entity object customerObj = customerUI.CustomerInfoListView.SelectedItem as CustomerInfo; //Load child window listview data to entity txtCustomerName.Text = customerObj.CustomerName; // set data to parent window text field txtCustomerId.Text = customerObj.Id.ToString();// set data to parent window text field this._customerInfoObj.Id = customerObj.Id; // set child window ID to parent window ID customerUI.Close(); //Close child window } }

C# with Entity, Send Data from Parent Form to Child Form

In Child Form Create an entity object as public and set all form field with that entity property. Like This code:

1 2 3 4 5 6 7 8 9 10 11 12 13

//Declare Purchase Entity Object as Public public PurchaseInfo _purchaseInfoObj = new PurchaseInfo(); //Load Purchase Data from Parent Window to Child Form public void LoadDataFromDueList() { txtProductID.Text = this._purchaseInfoObj.ProductId.ToString(); txtProductName.Text = this._purchaseInfoObj.ProductName; txtSupplierName.Text = this._purchaseInfoObj.SupplierName; txtTotalPurchaseAmount.Text = this._purchaseInfoObj.TotalPurchaseAmount.ToString(); txtTotalDue.Text = this._purchaseInfoObj.TotalDue.ToString(); }

Now in Parent Form, create an Event and write code like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14

//Collect Data from Listview and Send it to child form private void MakePaymentContexMenu_Click(object sender, RoutedEventArgs e) { if (PurchaseDueListView.SelectedIndex > -1) { SupplierDueCollectionUI supplierDueCollectionUI = new SupplierDueCollectionUI(); PurchaseInfo purchaseObj = new PurchaseInfo(); purchaseObj = PurchaseDueListView.SelectedItem as PurchaseInfo; // select and load data from listview supplierDueCollectionUI._purchaseInfoObj = purchaseObj; // send it to public entity _purchaseInfoObj supplierDueCollectionUI.LoadDataFromDueList(); // Call data load method from child form supplierDueCollectionUI.ShowDialog(); // show child form } }

WPF C# ComboBox with DataBind

Step - 1 (XAML)

1 2 3 4 5 6 7 8 9 10 11 12

<ComboBox HorizontalAlignment="Left" Margin="168,54,0,0" VerticalAlignment="Top" Width="197" x:Name="cmbProductCat"> <ComboBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding CategoryTitle}" Width="60"/> <!--<TextBlock Text="|"/> <TextBlock Text="{Binding DepartmentName}" Width="60"/>--> </StackPanel> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox>

Step - 2 (UI Code)

1 2 3 4 5 6 7 8 9

private void LoadProductCatComboBox() { cmbProductCat.Items.Clear(); _productCategoryInfoList = _productCategoryInfoManager.LoadAllProductCategoryInfo(); foreach (ProductCategoryInfo pCatInf in _productCategoryInfoList) { cmbProductCat.ItemsSource = _productCategoryInfoList; } }

Step - 3 (BLL)

1 2 3 4

public List<ProductCategoryInfo> LoadAllProductCategoryInfo() { return productCatInfoGetway.LoadAllProductCategoryInfo(); }

Step -4 (DAL)

1 2 3 4 5 6 7 8 9 10 11 12 13 14

public List<ProductCategoryInfo> LoadAllProductCategoryInfo() { List<ProductCategoryInfo> productCategoryInfoList = new List<ProductCategoryInfo>(); foreach (var p in (from c in dataContext.tbl_ProductCategories select c).Distinct()) { ProductCategoryInfo productCatInfoObj = new ProductCategoryInfo(); productCatInfoObj.Id = p.ID; productCatInfoObj.CategoryTitle = p.CategoriesTitle; productCategoryInfoList.Add(productCatInfoObj); } return productCategoryInfoList; }

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using DATA; using ENTITY; namespace DAL { public class CustomerInfoGetway { //Create object of my EntityFramework data model JSMSEntities dataContextObj = new JSMSEntities(); //Saving Customer Information public void SaveCustomerInfo(CustomerInfo _customerInfoObj) { var newCustomerInfo = new tbl_Customer { CustomerName = _customerInfoObj.CustomerName, CustomerAddress = _customerInfoObj.CustomerAddress, CustomerPhone = _customerInfoObj.CustomerPhone, CustomerMobile = _customerInfoObj.CustomerMobile, CustomerFax = _customerInfoObj.CustomerFax, CustomerEmail = _customerInfoObj.CustomerEmail, CustomerNote = _customerInfoObj.CustomerNote, }; dataContextObj.tbl_Customer.Add(newCustomerInfo); dataContextObj.SaveChanges(); } //Call data from database to ListView public List<CustomerInfo> LoadAllCustomerInfo() { dataContextObj = new JSMSEntities(); List<CustomerInfo> customerInfoList = new List<CustomerInfo>(); foreach (var c in (from p in dataContextObj.tbl_Customer select p).Distinct()) { CustomerInfo _customerInfoObj = new CustomerInfo(); _customerInfoObj.Id = c.ID; _customerInfoObj.CustomerName = c.CustomerName; _customerInfoObj.CustomerAddress = c.CustomerAddress; _customerInfoObj.CustomerPhone = c.CustomerPhone; _customerInfoObj.CustomerMobile = c.CustomerMobile; _customerInfoObj.CustomerFax = c.CustomerFax; _customerInfoObj.CustomerEmail = c.CustomerEmail; _customerInfoObj.CustomerNote = c.CustomerNote; customerInfoList.Add(_customerInfoObj); } return customerInfoList; } //Delete Customer Information public void DeleteCustomerInfo(CustomerInfo _customerInfoObj) { tbl_Customer customer = dataContextObj.tbl_Customer.First(c => c.ID == _customerInfoObj.Id); dataContextObj.tbl_Customer.Remove(customer); dataContextObj.SaveChanges(); } //Update Customer Information public void UpdateCustomerInfo(CustomerInfo _customerInfoObj) { var customerinfo = dataContextObj.tbl_Customer.First(c => c.ID == _customerInfoObj.Id); customerinfo.CustomerName = _customerInfoObj.CustomerName; customerinfo.CustomerAddress = _customerInfoObj.CustomerAddress; customerinfo.CustomerPhone = _customerInfoObj.CustomerPhone; customerinfo.CustomerMobile = _customerInfoObj.CustomerMobile; customerinfo.CustomerFax = _customerInfoObj.CustomerFax; customerinfo.CustomerEmail = _customerInfoObj.CustomerEmail; customerinfo.CustomerNote = _customerInfoObj.CustomerNote; dataContextObj.SaveChanges(); } } }

WPF C# Data Save, Update and Delete with 3 layer architecture - Part 1(Entity Class)

In ENTITY class library project, add a class and name it CustomerInfo.cs or whatever you want.
Now Use this code to your Entity class.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76
