UIHierarchy.SelectDown Method

Namespace:  EnvDTE
Assembly:  EnvDTE (in EnvDTE.dll)

Syntax

'Declaration
Sub SelectDown ( _
    How As vsUISelectionType, _
    Count As Integer _
)
void SelectDown(
    vsUISelectionType How,
    int Count
)
void SelectDown(
    [InAttribute] vsUISelectionType How, 
    [InAttribute] int Count
)
abstract SelectDown : 
        How:vsUISelectionType * 
        Count:int -> unit
function SelectDown(
    How : vsUISelectionType, 
    Count : int
)

Parameters

  • Count
    Type: System.Int32

    Required. The number of nodes to select down from the current node. Count is also used for coalescing commands while recording. That is, if you type SHIFT + DOWN ARROW four times, rather than four lines of code emitted, you instead get one line with a Count value of 4.

Remarks

SelectDown is useful for SHIFT-click macro recording or moving down or up with the arrow keys. It is useful because the behavior of SelectDown mimics the behavior of using the ARROW and SHIFT+ARROW keys in a tree view.

Examples

Sub SelectDownExample()
   Dim UIH As UIHierarchy = _
     DTE.Windows.Item(Constants.vsWindowKindMacroExplorer).Object
   Dim UIHItem As UIHierarchyItem = UIH.GetItem("Macros\Samples")

   UIHItem.Select(vsUISelectionType.vsUISelectionTypeSetCaret)
   If UIHItem.IsSelected = False Then
      If UIH.UIHierarchyItems.Expanded = True Then
         MsgBox("Node is expanded.")
      Else
         MsgBox("Node is not expanded.")
      End If
   End If
   UIH.SelectDown(vsUISelectionType.vsUISelectionTypeSelect, 2)
   UIH.DoDefaultAction()
   UIH.SelectDown(vsUISelectionType.vsUISelectionTypeSelect, 1)
   UIH.SelectUp(vsUISelectionType.vsUISelectionTypeExtend, 1)
End Sub
