Public ReadOnly Property DefaultView As BaseView

Property Value

Type Description
BaseView

A BaseView descendant representing the currently maximized detail clone.

Remarks

The grid control enables you to maximize detail clones so that they are displayed as the main View. In this case, you can determine the currently maximized clone by reading the DefaultView property value. When no detail clone is maximized, the DefaultView property value matches the GridControl.MainView property value.

Please refer to the Master-Detail Relationships topic for details on maximizing detail clones.

Note: when the DefaultView property value changes, the GridControl.DefaultViewChanged event is raised.

Examples

The example below shows how to maximize a detail View.

If the detail View does not exist, we should create it by expanding a specific master row. In our case, we obtain and work with the detail corresponding to the first master row.

After the master row is expanded, the detail View is obtained via GridView.GetDetailView.

Then the detail is maximized using the BaseView.ZoomView method. After that, the detail object and the GridControl.DefaultView property refer to the same maximized detail.

We use GridControl.DefaultView to group detail data rows by the "FUNCTION" column.

    int rowHandle = 0;
    //Create the first detail by expanding a master row
    GridView gView = gridControl1.MainView as GridView;
    gView.SetMasterRowExpanded(rowHandle, true);
    //Get the first detail
    BaseView detail = gView.GetDetailView(rowHandle);
    if (detail != null) {
        detail.ZoomView();
        //Access the detail via DefaultView
        //Group by the FUNCTION column
        (gridControl1.DefaultView as GridView).Columns["FUNCTION"].GroupIndex = 0;
    }
