公共类MyDataGrid
继承DataGrid
私有_processVars作为ProcessVariables
Private _sortDir As String =" NONE"
Private _sortVar As String =" NONE"
受保护的覆盖Sub OnMouseDown（ByVal e作为
System.Windows.Forms.MouseEventArgs）
Dim pt As New Point（eX，eY）
Dim hit As DataGrid.HitTestInfo = Me.HitTest（pt）
如果hit.Type = HitTestType.ColumnHeader AndAlso（hit.Column = 1或
hit.Column = 2）然后
Dim col As String =
Me.TableStyles（0）.GridColumnStyles（hit.Column）.Map pingName
如果Me._sortVar.Equals（col）那么
如果hit.Column = 1那么
如果Me._sortDir.Equals（" ASC"）那么
Me._sortDir =" DESC"
ElseIf Me._sortDir =" DESC"然后
Me._sortDir =" NONE"
Else
Me._sortDir =" ASC"
结束如果
否则
如果Me._sortDir.Equals（" ASC"）那么
Me._sortDir =" DESC"
否则
Me._sortDir =" ASC"
结束如果
Else
Me._sortDir =" DESC"
Me._sortVar = col
结束如果
Me._processVars.SortGrid（Me，Me._sortDir，Me._sortVar）
返回''不要调用baseclass
结束If

Public WriteOnly Property ProcessVars（）As ProcessVariables
Set（ByVal Value As ProcessVariables）
Me._processVars = Value
结束集

I have the following Class, but I would like to make one of the columns in
my DataGrid editable, how would I do that? When I use this class none of
the columns are editable even when I set the ReadOnly property to false?
Thanks
Peter

Pieter给了我们一个很好的样本来做这个伎俩。您可以使所有其他
列不可编辑，以使一列可编辑。
