Namespace: Kettic.AspNet.Controls
Assembly: Kettic.AspNet.Controls (in Kettic.AspNet.Controls.dll) Version: 2014.4.1129.0 (2014.04.1129.0)

Syntax

C++

Copy

public override string DataFieldParentID { get; set; }

Public Overrides Property DataFieldParentID As String
	Get
	Set

public:
virtual property String^ DataFieldParentID {
	String^ get () override;
	void set (String^ value) override;
}

abstract DataFieldParentID : string with get, set
override DataFieldParentID : string with get, set

Property Value

Type: String
A string that specifies the field of the data source that will be the "parent" column during databinding. The default is empty string.

Remarks

KaxTabControl requires both DataFieldID and DataFieldParentID properties to be set in order to be hierarchically databound.

The value of the column specified by DataFieldParentID must be null (Nothing) for root tabs. This is a requirement for databinding KaxTabControl.

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()
