Gets or sets the type of object whose public properties identify data-aware control columns.
Namespace : DevExpress.Data
Assembly : DevExpress.Data.v25.2.dll
NuGet Package : DevExpress.Data
[DefaultValue(null)]
public Type RowType { get; set; }
<DefaultValue(Nothing)>
Public Property RowType As Type
| Type | Default | Description |
|---|---|---|
| Type | null |
The row object’s type.

Specify the RowType property at design time to populate the bound grid control with columns. For example, the sample Data class contains multiple child classes, one of them is Order.
public class Data
{
public class Order
{
public Order(int _id, DateTime _orderDate, string _name, int _count)
{
ID = _id;
OrderDate = _orderDate;
ProductName = _name;
OrderCount = _count;
}
public int ID { get; set;}
public DateTime OrderDate { get; set; }
public string ProductName { get; set; }
public int OrderCount { get; set; }
}
}
Public Class Data
Public Class Order
Public Sub New(
ByVal _id As Integer,
ByVal _orderDate As Date,
ByVal _name As String,
ByVal _count As Integer)
ID = _id
OrderDate = _orderDate
ProductName = _name
OrderCount = _count
End Sub
Public Property ID() As Integer
Public Property OrderDate() As Date
Public Property ProductName() As String
Public Property OrderCount() As Integer
End Class
End Class
If you want a data-aware control to display Order entities, set the RowType property to the related type.
virtualServerModeSource1.RowType = typeof(virtDS.Data.Order);
virtualServerModeSource1.RowType = GetType(virtDS.Data.Order)
When you set this VirtualServerModeSource component as a data source for a Data Grid, the Grid generates columns for all data fields found in the class referenced by the RowType property.
At runime, the control fires the AcquireInnerList event if the RowType property is not set. Handle this event to manually supply a list that will store rows fetched by VirtualServerModeSource’s events. If neither the AcquireInnerList event is handled nor the RowType property is set, the source is unable to retrieve column information and a data-aware control bound to this source is empty.
