DataGrid in WPF

 Regarding wpf projects, tables are the most common controls for data. The DataGrid is a control to display data. Let's explain the various properties of the DataGrid and the application of the table.

   The first is to bind the DataGrid to the data, set the ItemSource property to the IEnumerable implementation. Each row in the data grid is bound to an object of the data source, and each column in the data grid is bound to a property of the data object. To automatically update the DataGrid UI when items are added or removed from the source data. The DataGrid must be bound to a collection that implements the interface.

  That's when it comes to data binding: it refers to the process of establishing a connection between an application's UI and the data it displays. If the binding has the correct settings and the data provides the correct notifications. then when the data changes its value, the elements bound to the data automatically reflect the change.

  Next is the column, there are 4 types: 1. Data grid text column. 2. Data grid checkbox column. 3. Data grid combo box columns. 4. Data grid hyperlink column. Corresponding data types: String, Boolean, Enum, Uri.

  The following list:

  When autogenerating columns, you can handle the AutoGeneratingColumn event to customize or cancel the column before adding it to the DataGrid . If both user-defined columns and auto-generated columns are added to the DataGrid , the user-defined columns are added first. To rearrange the display order of columns, you can set the DisplayIndex property for individual columns.

You can prevent automatic column generation by setting the AutoGenerateColumns property to . This is useful if you want to create and configure all columns explicitly.false

If the built-in column types do not meet your needs, use the DataGridTemplateColumn type to define custom columns. The DataGridTemplateColumn type provides CellTemplate and CellEditingTemplate properties that allow you to specify content templates for display and editing modes. For example, you can define custom columns for dates. The CellTemplate can define a TextBlock to display the date, while the CellEditingTemplate can define a DatePicker control to edit the date.

You can programmatically add, insert, delete, and change any column in a control at run time using the Columns collection. Check the IsAutoGenerated property to determine whether the column is auto-generated or user-defined. When the ItemsSource changes, the auto-generated columns are automatically added, removed, or regenerated.
