Access the nested tables
You can get access to a nested table inside a record using the following code example. In the following code example, you can get the specific record, or you can get all the records through the Records collection of the nested table.
C#
private void button1_Click(object sender, EventArgs e) { //You can get access to a nested table inside a record whereas n is the specific record that owns the nested table. NestedTable nt = this.gridGroupingControl1.Table.Records[3].NestedTables[0]; ChildTable ct = nt.ChildTable; //To get access to a specific record in that child table Record recordInNestedTable = ct.Records[3]; //To get access to all records in that child table foreach (Record rec in ct.Records) { // this.richTextBox1.Text += rec.ToString(); //[or] this.richTextBox1.Text += rec.GetValue("childID") + "\t" + rec.GetValue("Name").ToString() + "\n"; } }
VB
Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs) 'You can get access to a nested table inside a record whereas n is the specific record that owns the nested table. Dim nt As NestedTable = Me.gridGroupingControl1.Table.Records(3).NestedTables(0) Dim ct As ChildTable = nt.ChildTable 'To get access to a specific record in that child table Dim recordInNestedTable As Record = ct.Records(3) 'To get access to all records in that child table For Each rec As Record In ct.Records ' this.richTextBox1.Text += rec.ToString(); '[or] Me.richTextBox1.Text += rec.GetValue("childID") + Constants.vbTab + rec.GetValue("Name").ToString() & Constants.vbLf Next rec End Sub
