能否当鼠标悬停在某一个单元格时，鼠标光标显示为手型光标，并且改变网格行的外观?DevExpress XtraGrid当然可以实现该功能。你需要处理网格视图中的MouseMove和RowCellStyle事件，代码如下：
[C#]
using DevExpress.XtraGrid.Views.Grid;
private int hotTrackRow = DevExpress.XtraGrid.GridControl.InvalidRowHandle;
private int HotTrackRow {
get {
return hotTrackRow;
}
set {
if(hotTrackRow != value) {
int prevHotTrackRow = hotTrackRow;
hotTrackRow = value;
gridView1.RefreshRow(prevHotTrackRow);
gridView1.RefreshRow(hotTrackRow);
if(hotTrackRow >= 0)
gridControl1.Cursor = Cursors.Hand;
else
gridControl1.Cursor = Cursors.Default;
}
}
}
private void gridView1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e) {
GridView view = sender as GridView;
GridHitInfo info = view.CalcHitInfo(new Point(e.X, e.Y));
if(info.InRowCell)
HotTrackRow = info.RowHandle;
else
HotTrackRow = DevExpress.XtraGrid.GridControl.InvalidRowHandle;
}
private void gridView1_RowCellStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowCellStyleEventArgs e) {
if(e.RowHandle == HotTrackRow)
e.Appearance.BackColor = Color.PaleGoldenrod;
}
[VB.NET]
Imports DevExpress.XtraGrid
Imports DevExpress.XtraGrid.Views.Grid
Private HotTrackRowValue As Integer = GridControl.InvalidRowHandle
Private Property HotTrackRow() As Integer
Get
Return HotTrackRowValue
End Get
Set(ByVal Value As Integer)
If HotTrackRowValue <> Value Then
Dim PrevHotTrackRow As Integer
PrevHotTrackRow = HotTrackRowValue
HotTrackRowValue = Value
GridView1.RefreshRow(PrevHotTrackRow)
GridView1.RefreshRow(HotTrackRowValue)
If HotTrackRowValue >= 0 Then
GridControl1.Cursor = Cursors.Hand
Else
GridControl1.Cursor = Cursors.Default
End If
End If
End Set
End Property
Private Sub GridView1_MouseMove(ByVal sender As System.Object, ByVal e As MouseEventArgs) Handles GridView1.MouseMove
Dim View As GridView = CType(sender, GridView)
With View.CalcHitInfo(New Point(e.X, e.Y))
If .InRowCell Then
HotTrackRow = .RowHandle
Else
HotTrackRow = GridControl.InvalidRowHandle
End If
End With
End Sub
Private Sub GridView1_RowCellStyle(ByVal sender As Object, ByVal e As RowCellStyleEventArgs) Handles GridView1.RowCellStyle
If e.RowHandle = HotTrackRow Then
e.Appearance.BackColor = Color.PaleGoldenrod
End If
End Sub
