C1TrueDBGrid.Bands Property

Gets the number of levels within a hierarchical grid.

[Visual Basic]

Public ReadOnly Property Bands As Integer

[C#]

public int Bands {get;}

[Delphi]

public property Bands: Int32 read get_Bands;

Remarks

When a grid is bound to a master-detail data source, display related groups of hierarchical data using bands. A band is created for each level in a hierarchical recordset, and may consist of entire tables or a just a few selected fields. A band is a virtual representation of a hierarchical recordset; it is not the data itself.

The Bands property is provided for cases where the number of levels in a hierarchical recordset is not known in advance.

Example

The following example uses the Bands property and the ExpandBand method to display all available bands:

· Visual Basic

Dim n As Integer

For n = 0 To Me.C1TrueTDBGrid1.Bands - 1

Me.C1TrueDBGrid1.ExpandBand(n)

Next n

· C#

int n;

for ( n = 0 ; n < this.C1TrueTDBGrid1.Bands)

{

this.c1TrueDBGrid1.ExpandBand(n);

}

· Delphi

var n: Integer;

for n := 0 To Self.C1TrueTDBGrid1.Bands - 1 do

Self.C1TrueDBGrid1.ExpandBand(n);
