For ComboBox:        private void LoadVendorTYpeComboBox()         {             vendorTYpecomboBox.Items.Clear();             ObjVendorTypeList = ObjBvendorType.GetAllVendirType();             foreach (EVendorType obj in ObjVendorTypeList)             {                 vendorTYpecomboBox.Items.Add(obj.VendorType);             }                    } For ListView:     private void LoadVendorTypeListView()         {             vendorTypelistView.Items.Clear();             ObjVendorTypeList = ObjBvendorType.GetAllVendirType();             foreach (EVendorType obj in ObjVendorTypeList)             {                 vendorTypelistView.Items.Add(obj);             }         } for listview you have to bind the object in list column. <GridViewColumn DisplayMemberBinding="{Binding Path=VendorType}"  Header="Vendor Type" Width="100"/> E

List view selection change is one of interesting matter in WPF. When you will select the item from list view. It will automatically fill field of the corrosponding item. Consider the following Selection change Event:  private void unitNamelistView_SelectionChanged(object sender, SelectionChangedEventArgs e)         {             if (unitNamelistView.SelectedIndex > -1)             {    /*====Setting Selected item in Entity=====*/                 EUnitMeasurement seletedUnit = (EUnitMeasurement)unitNamelistView.SelectedItem;                 /*==== Filling UI Field From entity======*/     unitIDtextBox.Text = seletedUnit.Id;                 unitAbbrivationtextBox.Text = seletedUnit.UnitName;                 fullNameUnittextBox.Text = seletedUnit.FullNameOfUnit;                 unitCommenttextBox.Text = seletedUnit.UnitComment;                }         } Enjoy....!!

if you want to select Listview item in Textfield value change you can do it by the code in text Change Event: private void textBox1_TextChanged(object sender, TextChangedEventArgs e) { string typeID = textBox1.Text; for (int i = 0; i < unitNamelistView.Items.Count; i++) { EUnitMeasurement aWHType = (EUnitMeasurement)unitNamelistView.Items[i]; if (aWHType.UnitName == typeID) { unitNamelistView.SelectedIndex = i; break; } } }

To Get all Country Name in your program now you no need to use Enum or load from Database. Microsoft .NET give All Country Name using this code. ** You need to use namesapce: using System.Globalization; Create a Method in Load event of your UI and Implement it as Following:     private void PopulateCountryComboBox()         {             RegionInfo country = new RegionInfo(new CultureInfo("en-US", false).LCID);             List<string> countryNames = new List<string>();             foreach (CultureInfo cul in CultureInfo.GetCultures(CultureTypes.SpecificCultures))             {                 country = new RegionInfo(new CultureInfo(cul.Name, false).LCID);                 countryNames.Add(country.DisplayName.ToString());             }             IEnumerable<string> nameAdded = countryNames.OrderBy(names => names).Distinct();             foreach (string item in nameAdded)             {                 supplierCountryComboBox.Items.Add(

You can use wpf validator more smooth as ajax/ jquery. Just complete the following with me.  Step 1.        Open A new Window in WPF Step 2. Add a class Which will provide the Validation           /************ StringAtikStringValidationRule ************/ using System.Globalization; using System.Windows.Controls; namespace WpfApplication4 {     public class StringAtikStringValidationRule : ValidationRule     {         private int _minimumLength = -1;         private int _maximumLength = -1;         private string _errorMessage;         public int MinimumLength         {             get { return _minimumLength; }             set { _minimumLength = value; }         }         public int MaximumLength         {             get { return _maximumLength; }             set { _maximumLength = value; }         }         public string ErrorMessage         {             get { return _errorMessage; }             set { _errorMessage = value; }         }       

UI field validation in WPF is a one of most important. Because when the field can't get the Specific class then it will get Error. So it better to create a CheckField()   for specific Button Event & there you can implement the method as: / ******************* A Button Event *****************/          private void appointAddButton_Click(object sender, RoutedEventArgs e)         {             AddAppointmentInListView();         }      /************** Implement AddAppointmentInListView Method *****************/         private void AddAppointmentInListView()         {             try             {                 if (CheckField())                 {                     EAppointment objAppointment = new EAppointment();                     objAppointment.TrackNo = Convert.ToInt64(employeeTrackNoTextBox.Text);                     objAppointment.InterviewId = Convert.ToInt64(employeeIdTextBox.Text);                     objAppointment.AppointmentDate =  appointDateD

 Uploading Picture in UI is very Important It is Quite Easy. On upload button Event Write down The following code:                 OpenFileDialog dlg;                 FileStream fs;                byte[] data;               dlg = new Microsoft.Win32.OpenFileDialog();               dlg.ShowDialog();                if (dlg.FileName == "")             {                 MessageBox.Show("Picture is not selected......");             }             else             {                 fs = new FileStream(dlg.FileName, FileMode.Open, FileAccess.Read);                 data = new byte[fs.Length];                 fs.Read(data, 0, System.Convert.ToInt32(fs.Length));                 fs.Close();                 ImageSourceConverter imgs = new ImageSourceConverter();                 SupplierLogoimage.SetValue(Image.SourceProperty, imgs.ConvertFromString(dlg.FileName.ToString())); EnJoy....... !!

The Random class defined in the .NET Framework class library provides functionality to generate random numbers.   The Random class constructors have two overloaded forms. It takes either no value or it takes a seed value. The Random class has three public methods - Next, NextBytes, and NextDouble. The Next method returns a random number, NextBytes returns an array of bytes filled with random numbers, and NextDouble returns a random number between 0.0 and 1.0. The Next method has three overloaded forms and allows you to set the minimum and maximum range of the random number.                 int newTicketNumber;                 int ticketnumber = Convert.ToInt32(lastTicNotextBox.Text);                 Random random =new Random();                 newTicketNumber = random.Next(ticketnumber);                 newticnomtextBox.Text = newTicketNumber.ToString();
