DataGrid
This class is the successor to the old unmanaged FlexGrid control, and has considerably more power, fully supporting complex data-binding scenarios. A grid offers a two dimensional view of the rows and columns on a data source. The data source itself may consist of several related tables, each with different rows and columns, so the grid offers support for drilling down through these relations, updating the display to reflect the current view on the data. There are a variety of basic areas in the grid whose appearance you can change. You can show and hide a caption (title) area with the CaptionVisible property. You can set the CaptionFont , CaptionForeColor , and CaptionBackColor , as well as the CaptionText . If a particular row in the data source has been defined to have relations to another table, the grid displays a hyperlink for you to click on to follow that relation. You can set its LinkColor and LinkHoverColor . This drill-down behavior is enabled and disabled with the AllowNavigation property. When you have drilled down into a table, a line is added to display the parent rows through which you have navigated. You can set the ParentRowsBackColor , ParentRowsForeColor , and visibility ( ParentRowsVisible ). In addition, you can set the ParentRowsLabelStyle to display either the parent ColumnName , TableName , or both. You can also NavigateTo() a particular row and relation, or NavigateBack() to the parent of the current view. Then, there are the column headers (which run across the top of the grid) and the row headers (which run down the side of the grid). You can make the ColumnHeadersVisible and the RowHeadersVisible , and also set the RowHeaderWidth . Their appearance can be modified with the HeaderBackColor , HeaderForeColor , and HeaderFont . (Note that this means the row and column headers must have the same basic appearance). Finally, there are the data rows themselves . You can optionally display gridlines between the rows and/or columns by setting GridLineStyle and GridLineColor . You can set a PreferredRowHeight property that acts as a hint for the default row height, and find out the number of displayed rows using the VisibleRowCount property. Rows can be selected, either with the mouse or programmatically through the Select() and UnSelect () methods (note the capital "S"), and you can set the SelectionForeColor and SelectionBackColor . The IsSelected() method determines the selection state of a particular row, and the CurrentRowIndex property tells you which row is currently selected. You can also set an AlternatingBackColor property to enable a ledger-like appearance for unselected rows. The columns divide each row up into a series of cells . You can get the identity of the CurrentCell . Alternatively, you can get or set the value of a particular cell using the Item property (which is the indexer property). The display bounds of a particular cell can be retrieved using the GetCellBounds() method, or GetCurrentCellBounds() for the cell with the focus. You can choose whether the columns should be sorted by clicking on their headers by setting the AllowSorting property. By default, the system automatically generates all the columns needed for each of the tables in the data source, generating textual, numeric, and Boolean columns as appropriate. However, you can also take control over the entire grid through the TableStyles property. This allows you to set up custom columns for each table. (See DataGridTableStyle and DataGridColumnStyle for more information on this feature of data grids.) Note that you must add your DataGridColumnStyle objects to your DataGridTableStyle objects before you add the table styles to the DataGrid , or the framework will handily create a default set of columns for you. public class DataGrid : Control : System.ComponentModel.ISupportInitialize, IDataGridEditingService { // Public Constructors public DataGrid ();
