我可以通过使用propgrid.Focus将焦点设置到我的属性网格 - 但是我怎样才能设置始终优先的默认属性？
或者只是将焦点设置为

默认属性？可以这样做吗？

I can set focus to my property grid by using propgrid.Focus - but how can I

推荐答案

嗨Derek，

在PropertyGrid控件中选择（或聚焦）预定义属性

以编程方式，您可以使用循环GridItems并选中label

来确定要选择的项目：

'' - ----开始-----

Dim GridItem As GridItem = PropertyGrid1.SelectedGridItem

Dim pGridItem As GridItem = GridItem.Parent

对于每个egi作为GridItem在pGridItem.GridItems中

如果egi.Label =" property_label_here"然后

PropertyGrid1.Focus（）

egi.Select（）

结束如果

''------结束-------

希望这会有所帮助，

Hi Derek,

To select(or focus) a pre-defined property in a PropertyGrid control
programmatically, you can use loop through GridItems and check "label"
to determine which item to be selected:

''------Begin-----
Dim GridItem As GridItem = PropertyGrid1.SelectedGridItem
Dim pGridItem As GridItem = GridItem.Parent
For Each egi As GridItem In pGridItem.GridItems
If egi.Label = "property_label_here" Then
PropertyGrid1.Focus()
egi.Select()
End If
Next
''------End-------
Hope this helps,

据我所知（我猜不好），你想要像智能感知或设置那样的b $ b

文本框中的属性值，并且在PropertyGrid外部设置PropertyGrid项的值

控制是不可能的，因为值是属性是ReadOnly。

或者，我的另一个猜测，如果你想要突出显示属性网格

项目，它是在PropertyGrid控件内，而初始键匹配

，文本框中的文字你可以使用：

''--------------开始----- --------

Private Sub TextBox1_KeyDown（ByVal sender As System.Object，_

ByVal e As System.Windows.Forms.KeyEventArgs）_

处理TextBox1.KeyDown

Dim GridItem As GridItem = _

PropertyGrid1.SelectedGridItem

Dim pGridItem As GridItem = _

GridItem.Parent

For Each egi GridItem In _

pGridItem.GridItems

if egi .Label.StartsWith（e.KeyData.ToString）然后

PropertyGrid1.Focus（）

egi.Select（）

结束如果

HTH，

As far as i understand (i couldn''t guess well maybe), you''re wanting
something like IntelliSense or setting the value of a property within
textbox, and setting PropertyGrid item''s value outside PropertyGrid
control is not possible, because "Value" property is ReadOnly.

Or, my another guess that if you want to highlight a property grid
item which is inside PropertyGrid control while initial key matches
with the text in textbox you can use that:

''--------------Begin-------------
Private Sub TextBox1_KeyDown(ByVal sender As System.Object, _
ByVal e As System.Windows.Forms.KeyEventArgs) _
Handles TextBox1.KeyDown

Dim GridItem As GridItem = _
PropertyGrid1.SelectedGridItem
Dim pGridItem As GridItem = _
GridItem.Parent
For Each egi As GridItem In _
pGridItem.GridItems
If egi.Label.StartsWith(e.KeyData.ToString) Then
PropertyGrid1.Focus()
egi.Select()
End If
Next

End Sub
''--------End----------

HTH,
