Dim relation As String
Dim value As ISheetDataModel
 
value = instance.GetChildDataModel(row, relation)

public ISheetDataModel GetChildDataModel( 
   int row,
   string relation

Parameters

row: Row whose child data model is to be returned
relation: Data relation name

Return Value

Example

This example illustrates the use of this member by returning the name of the child model at the specified index. This example assumes the existence of two data tables with the appropriate relations established.

System.Data.DataSet ds = new System.Data.DataSet();
DataTable name; 
DataTable city; 
name = ds.Tables.Add("Customers"); 
name.Columns.AddRange(new DataColumn[] {new DataColumn("LastName", typeof(string)), new DataColumn("FirstName", typeof(string)),
new DataColumn("ID", typeof(Int32))}); 
name.Rows.Add(new object[] {"Fielding", "William", 0}); 
name.Rows.Add(new object[] {"Williams", "Arthur", 1}); 
name.Rows.Add(new object[] {"Zuchini", "Theodore", 2}); 
city = ds.Tables.Add("City/State"); 
city.Columns.AddRange(new DataColumn[] {new DataColumn("City", typeof(string)), new DataColumn("Owner", typeof(Int32)), new
DataColumn("State", typeof(string))}); 
city.Rows.Add(new object[] {"Atlanta", 0, "Georgia"}); 
city.Rows.Add(new object[] {"Boston", 1, "Mass."}); 
city.Rows.Add(new object[] {"Tampa", 2, "Fla."}); 
ds.Relations.Add("City/State", name.Columns["ID"], city.Columns["Owner"]); 
FarPoint.Win.Spread.Model.ISheetDataModel isdm;
FarPoint.Win.Spread.Model.DefaultSheetDataModel dataModel = new FarPoint.Win.Spread.Model.DefaultSheetDataModel(5, 5);
fpSpread1.ActiveSheet.Models.Data = dataModel;
dataModel.DataSource = ds;
dataModel.DataMember = "Customers";
isdm = dataModel.GetChildDataModel(0, "City/State");
listBox1.Items.Add(Convert.ToString(isdm.ColumnCount));

Visual Basic
