   ByVal index As Integer _
) As String

'Usage
 
Dim instance As DefaultSheetDataModel
Dim index As Integer
Dim value As String
 
value = instance.GetChildRelation(index)

public string GetChildRelation( 
   int index
)

Parameters

index: Index of the child data relation

Return Value

Example

This example illustrates the use of this member by returning the name of the child relation 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; 
string s;
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.DefaultSheetDataModel dataModel = new FarPoint.Win.Spread.Model.DefaultSheetDataModel(5, 5);
fpSpread1.ActiveSheet.Models.Data = dataModel;
dataModel.DataSource = ds;
dataModel.DataMember = "Customers";
s = dataModel.GetChildRelation(0);
listBox1.Items.Add(s);
