Question

我想知道vb.net中是否有datagridview标题右键单击事件。

在我的vb.net项目中，我有一个datagridview，每当我右键单击标题部分时，应用程序都会崩溃。有没有办法避免崩溃，例如添加事件处理程序或任何其他方法？

感谢。

与datagrid相关的代码：

UPDATE1 ：

我的代码与datagrid有关，如下所示：

Private Sub Result_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    Try
        logger = log4net.LogManager.GetLogger("MyProject")
        logger.Info("Result_Load() - Start")

        Using connObj As New SqlClient.SqlConnection(My.Settings.dbConnectionString)
            connObj.Open()

            gridSql = "SELECT USER_ID, USER_NAME, USER_ADDRESS, USER_EMAIL FROM USER_DETAILS " & vbCrLf &
                      "WHERE USER_ID IN (" + Attribute.allUserSelected + ")"   
' the Attribute.allUserSelected is pass from another form

            logger.Info("gridSql= " + gridSql)

            Try
                adapter = New SqlDataAdapter(gridSql, connObj)
                adapter.Fill(ds)
                connObj.Close()
                DataGridView1.DataSource = ds.Tables(0)
            Catch ex As Exception
                MsgBox(ex.ToString)
            End Try
        End Using

    Catch ex As Exception
        MsgBox(ex.ToString)
        logger.Error(ex.ToString)

        Return
    End Try

End Sub


Private Sub dataGridView1_ColumnHeaderMouseClick(ByVal sender As Object, ByVal e As DataGridViewCellMouseEventArgs) Handles DataGridView1.ColumnHeaderMouseClick
    MsgBox("click the header....") 
   'I can get the message here
    If (e.Button = MouseButtons.Right) Then
        MsgBox("right click the header......") 
        'cannot get this ,message, crash immediately
    End If
end Sub

请告诉我，谢谢。

这种情况来得太晚了，但不会怀疑将来有些人会这么做。

   DataGridView1. Columns ( 0). SortMode = DataGridViewColumnSortMode. NotSortable

您的列标题不会回复Left/Right Click
