C1TrueDBGrid.GroupColMove Event

Occurs whenever a column is moved into or out of the grouping area.

[Visual Basic]

Public Event GroupColMove As GroupColMoveEventHandler

[C#]

public event GroupColMoveEventHandler GroupColMove

[Delphi]

public property GroupColMove: GroupColMoveEventHandler read remove_GroupColMove write add_GroupColMove;

Remarks

The ColMoveEventArgs.Position property ranges from 0, which denotes the left edge, to the total number of columns, which denotes the right edge. A position of -1 is used to indicate that a column is being moved from the grouping area back to the grid.

To determine which column is being moved, use the Item method.

If the ColMoveEventArgs.Cancel property is set to True, no movement occurs. Selected columns always remain selected, regardless of the ColMoveEventArgs.Cancel setting.

See Column Grouping for more information.

Example

The following code uses GroupColMove event to automatically expand all groups after the user drags a column in the grouping area:

· Visual Basic

Private Sub C1TrueDBGrid1_GroupColMove(ByVal sender As Object, ByVal e As C1.Win.C1TrueDBGrid.GroupColMoveEventArgs) Handles C1TrueDBGrid1.GroupColMove

Dim col As Integer = e.ColIndex

If col >= 0 Then

Me.C1TrueDBGrid1.Columns(col - 1).GroupInfo.OutlineMode = C1.Win.C1TrueDBGrid.OutlineModeEnum.StartExpanded

End If

End Sub

· C#

private void c1TrueDBGrid1_GroupColMove(object sender, C1.Win.C1TrueDBGrid.GroupColMoveEventArgs e)

{

int col = e.ColIndex;

if (col >= 0)

{

this.c1TrueDBGrid1.Columns(col - 1).GroupInfo.OutlineMode = C1.Win.C1TrueDBGrid.OutlineModeEnum.StartExpanded;

}

· Delphi

procedure C1TrueDBGrid1_GroupColMove(sender: System.Object; e: C1.Win.C1TrueDBGrid.GroupColMoveEventArgs);

var

col : Integer;

begin

col := e.ColIndex;

if (col >= 0) then

Self.C1TrueDBGrid1.Columns((col - 1)).GroupInfo.OutlineMode := C1.Win.C1TrueDBGrid.OutlineModeEnum.StartExpanded;

end;
