Examples

The following example demonstrates how to use DataFieldID and DataFieldParentID.

C++

Copy

DataTable data = new DataTable();
data.Columns.Add("MyText");
data.Columns.Add("MyID", typeof(int));
data.Columns.Add("MyParentID", typeof(int));

data.Rows.Add(new object[] {"Root Tab 1", 1, null});
data.Rows.Add(new object[] {"Child Tab 1.1", 3, 1});
data.Rows.Add(new object[] {"Root Tab 2", 2, null});
data.Rows.Add(new object[] {"Child Tab 2.1", 4, 2});

KaxTabControl1.DataSource = data;
KaxTabControl1.DataTextField = "MyText";            //"MyText" column provides values for the Text property of databound tabs
KaxTabControl1.DataFieldID = "MyID";                //"MyID" column provides values for the "child" column in the relation.
KaxTabControl1.DataFieldParentID = "MyParentID";    //"MyParentID" column provides values for the "parent" column in the relation.
KaxTabControl1.DataBind();

Dim data As New DataTable()
data.Columns.Add("MyText")
data.Columns.Add("MyID", GetType(Integer))
data.Columns.Add("MyParentID", GetType(Integer))

data.Rows.Add(New Object() {"Root Tab 1", 1, Nothing})
data.Rows.Add(New Object() {"Child Tab 1.1", 3, 1})
data.Rows.Add(New Object() {"Root Tab 2", 2, Nothing})
data.Rows.Add(New Object() {"Child Tab 2.1", 4, 2})

KaxTabControl1.DataSource = data
KaxTabControl1.DataTextField = "MyText"            '"MyText" column provides values for the Text property of databound tabs
KaxTabControl1.DataFieldID = "MyID"                '"MyID" column provides values for the "child" column in the relation.
KaxTabControl1.DataFieldParentID = "MyParentID"    '"MyParentID" column provides values for the "parent" column in the relation.
KaxTabControl1.DataBind()
