I moved the following code to the latest version of RadGridView. The commented lines do not compile because the FieldDescriptors are obsolete. How do I change the obsolete code behind to the latest version of RadGridView. For the base Table I changed RadGridView1.TableDefinition.FieldDescriptors.Add(gridViewDataColumn);
to
RadGridView1.Columns.Add(gridViewDataColumn);



I don't know how to Add GridViewDataColumn to the child tables?  Xaml is not an option.



Thanks

Rich

InitializeComponent();

GridViewTableDefinition carDefinition = new GridViewTableDefinition();

//carDefinition.AutoGenerateFieldDescriptors = false;

gridViewDataColumn = new GridViewDataColumn();

gridViewDataColumn.Header = "Car Name";

gridViewDataColumn.DataMemberBinding = new Binding("CarName");

gridViewDataColumn.DataType = Type.GetType("System.String");

RadGridView1.Columns.Add(gridViewDataColumn);

//RadGridView1.TableDefinition.FieldDescriptors.Add(gridViewDataColumn);

gridViewDataColumn = new GridViewDataColumn();

gridViewDataColumn.Header = "Year";

gridViewDataColumn.DataMemberBinding = new Binding("Year");

gridViewDataColumn.DataType = Type.GetType("System.Int32");

RadGridView1.Columns.Add(gridViewDataColumn);

//RadGridView1.TableDefinition.FieldDescriptors.Add(gridViewDataColumn);

gridViewDataColumn = new GridViewDataColumn();

gridViewDataColumn.Header = "Mileage";

gridViewDataColumn.DataMemberBinding = new Binding("Mileage");

gridViewDataColumn.DataType = Type.GetType("System.Int32");

RadGridView1.Columns.Add(gridViewDataColumn);

//RadGridView1.TableDefinition.FieldDescriptors.Add(gridViewDataColumn);

GridViewTableDefinition modelDefinition = new GridViewTableDefinition();

//modelDefinition.AutoGenerateFieldDescriptors = false;

//modelDefinition.FieldDescriptors.Add(new GridViewDataColumn() { Header = "Model Name", DataMemberBinding = new Binding("ModelName"), DataType = Type.GetType("System.String") });

//modelDefinition.FieldDescriptors.Add(new GridViewDataColumn() { Header = "Horsepower", DataMemberBinding = new Binding("Horsepower"), DataType = Type.GetType("System.Int32") });

//modelDefinition.FieldDescriptors.Add(new GridViewDataColumn() { Header = "Wheelbase", DataMemberBinding = new Binding("Wheelbase"), DataType = Type.GetType("System.Int32") });

modelDefinition.Relation = new PropertyRelation("Models");

RadGridView1.TableDefinition.ChildTableDefinitions.Add(modelDefinition);

GridViewTableDefinition engineDefinition = new GridViewTableDefinition();

//engineDefinition.AutoGenerateFieldDescriptors = false;

//engineDefinition.FieldDescriptors.Add(new GridViewDataColumn() { Header = "Engine Name", DataMemberBinding = new Binding("EngineName"), DataType = Type.GetType("System.String") });

//engineDefinition.FieldDescriptors.Add(new GridViewDataColumn() { Header = "Block ID", DataMemberBinding = new Binding("BlockID"), DataType = Type.GetType("System.String") });

engineDefinition.Relation = new PropertyRelation("Engines");

modelDefinition.ChildTableDefinitions.Add(engineDefinition);

GridViewTableDefinition colorDefinition = new GridViewTableDefinition();

//colorDefinition.AutoGenerateFieldDescriptors = false;

//colorDefinition.FieldDescriptors.Add(new GridViewDataColumn() { Header = "Color Name", DataMemberBinding = new Binding("ColorName"), DataType = Type.GetType("System.String") });

//colorDefinition.FieldDescriptors.Add(new GridViewDataColumn() { Header = "Trim Package", DataMemberBinding = new Binding("TrimPackage"), DataType = Type.GetType("System.String") });

colorDefinition.Relation = new PropertyRelation("CarColors");

modelDefinition.ChildTableDefinitions.Add(colorDefinition);

Hi,

I used the DataLoading event and that woked perfectivley. I do however have another problem. I used the following code to set GridViewRow.IsExpandable.

private void RadGridView1_RowLoaded(object sender, RowLoadedEventArgs e)

{

GridViewRow row = e.Row as GridViewRow;

var dataElement = e.DataElement;

if (row != null && dataElement != null)

{

if (dataElement is Car)

{

if (((Car)dataElement).Models.Count > 0)

{

row.IsExpandable = true;

}

else

row.IsExpandable = false;

}

The problem is that I don't get a RowLoaded event for the child tables so that I can set the IsExpandable property. I assume that the grid is working properly since the child tables are attached to the main table. My class structure looks like the following:

Car
    Model
        Engine
        CarColor

I need to be able to set IsExpandable property for the Model class depending on the count being > 0 for the Engine and/or CarColor class.

Thanks
