Here's a simple way of adding/deleting WPF Datagrid rows using observable collection. XAML Code 1 2 3 4 5 6 7 8 <DataGrid AutoGenerateColumns= "False" ItemsSource= "{Binding}" Margin= "12,12,12,41" Name= "dataGrid1" CanUserResizeRows= "False" CommandManager.PreviewExecuted= "UserDataGrid_PreviewDeleteCommandHandler" RowEditEnding= "dataGrid1_RowEditEnding" RowHeaderWidth= "20" > <DataGrid.Columns> <DataGridTextColumn Binding= "{Binding UserName, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Header= "User name" Width= "230" > </DataGridTextColumn> <DataGridTextColumn Binding= "{Binding FirstName, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Header= "First Name" Width= "245" > </DataGridTextColumn> </DataGrid.Columns> </DataGrid> C# ...

In a post by codefornothing in which He demonstrate the use of IMultiValueConverter using DataTable: The WPF Datagrid and Me , I decided to create a similar post in which the binding source is of type collection (Observable Collection). I encountered a few issues like how to replace the Binding Path values from binding to a strongly type class instead of DataTable. To get things started, here are the snippets: Observable Class public class StudentList : ObservableCollection<Student> { public StudentList() { Add( new Student{ID = 1, Age = 29, Name = "Jerby" , Address= "Cebu" }); Add( new Student{ID = 2, Age = 28, Name = "Renz" , Address= "Cebu" }); Add( new Student{ID = 3, Age = 23, Name = "Aya" , Address= "Leyte" }); Add( new Student{ID = 4, Age = 33, Name = "Jeff" , Address= "Leyte" }); Add( new Student{ID = 5...

The snippet below sorts the Observable Collection object which is scriptInfo using time_start which is a property of a strongly typed class. scriptInfo.OrderBy(i => i.time_start); Cheers!

Hello, Assuming the databinding source of WPF Datagrid is of type ObservableCollection, the code below will loop through the WPF DataGrid. var row = GetDataGridRows(dgScripts); foreach (DataGridRow r in row) { CScriptsInfo info = (CScriptsInfo)r.Item; if (info.prog_name.ToString().Contains(txtScriptName.Text.Trim().ToUpper())) { r.IsSelected = true ; } }
