如何覆盖DevExpress GridView删除

我有一个表（

myTable

），我想从中删除行，但不想删除它们。我使用

myTable.ActiveFlag

使它们过期。因此，当我从

myTable

中“删除”一行时，我希望运行

updatemytable SET-ActiveFlag=0，其中id=@rowId

使用DevExpress

Gridcontrol

和

GridView

进行此操作的最佳方法是什么

我目前：

Private Sub gcMyTableMaintenance_EmbeddedNavigator_ButtonClick(ByVal sender As System.Object, ByVal e As DevExpress.XtraEditors.NavigatorButtonClickEventArgs) Handles gcMyTableMaintenance.EmbeddedNavigator.ButtonClick
    If e.Button.ButtonType = DevExpress.XtraEditors.NavigatorButtonType.Remove Then
        //'TODO: Remove Row
    End If
    e.Handled = True
End Sub

我想在这里运行一个存储过程或SQL语句，但是有更简单或更合适的方法吗

以下是我的最终代码的基本版本：

Private Sub gcMyTableMaintenance_EmbeddedNavigator_ButtonClick(ByVal sender As System.Object, ByVal e As DevExpress.XtraEditors.NavigatorButtonClickEventArgs) Handles gcMyTableMaintenance.EmbeddedNavigator.ButtonClick
    If e.Button.ButtonType = DevExpress.XtraEditors.NavigatorButtonType.Remove Then
        Dim iMyTableId As Int32 = 0

        iMyTableId = gvMyTableMaintenance.GetFocusedRowCellValue("id")

        Using conn As New SqlConnection(MyConnectionString)
            Using lCmd As New SqlCommand()
                Try
                    lCmd.Connection = conn
                    lCmd.CommandType = CommandType.StoredProcedure
                    lCmd.CommandText = "ExpireFromMyTable"
                    lCmd.Parameters.AddWithValue("@myTableId", iMyTableId)
                    conn.Open()
                    lCmd.ExecuteNonQuery()
                    conn.Close()

                    //'Need to delete from 
                    gvMyTableMaintenance.DeleteRow(gvMyTableMaintenance.FocusedRowHandle)
                Catch ex As Exception
                    //'Handle Exception
                End Try
            End Using
        End Using
    End If
    e.Handled = True
End Sub

Private Sub gcMyTableMaintenance_EmbeddedNavigator_ButtonClick(ByVal sender As System.Object, ByVal e As DevExpress.XtraEditors.NavigatorButtonClickEventArgs) Handles gcMyTableMaintenance.EmbeddedNavigator.ButtonClick
    If e.Button.ButtonType = DevExpress.XtraEditors.NavigatorButtonType.Remove Then
        Dim iMyTableId As Int32 = 0

        iMyTableId = gvMyTableMaintenance.GetFocusedRowCellValue("id")

        Using conn As New SqlConnection(MyConnectionString)
            Using lCmd As New SqlCommand()
                Try
                    lCmd.Connection = conn
                    lCmd.CommandType = CommandType.StoredProcedure
                    lCmd.CommandText = "ExpireFromMyTable"
                    lCmd.Parameters.AddWithValue("@myTableId", iMyTableId)
                    conn.Open()
                    lCmd.ExecuteNonQuery()
                    conn.Close()

                    //'Need to delete from 
                    gvMyTableMaintenance.DeleteRow(gvMyTableMaintenance.FocusedRowHandle)
                Catch ex As Exception
                    //'Handle Exception
                End Try
            End Using
        End Using
    End If
    e.Handled = True
End Sub

在我看来，您选择了实现此功能的正确方法。

以下是我最终代码的基本版本：

Private Sub gcMyTableMaintenance_EmbeddedNavigator_ButtonClick(ByVal sender As System.Object, ByVal e As DevExpress.XtraEditors.NavigatorButtonClickEventArgs) Handles gcMyTableMaintenance.EmbeddedNavigator.ButtonClick
    If e.Button.ButtonType = DevExpress.XtraEditors.NavigatorButtonType.Remove Then
        Dim iMyTableId As Int32 = 0

        iMyTableId = gvMyTableMaintenance.GetFocusedRowCellValue("id")

        Using conn As New SqlConnection(MyConnectionString)
            Using lCmd As New SqlCommand()
                Try
                    lCmd.Connection = conn
                    lCmd.CommandType = CommandType.StoredProcedure
                    lCmd.CommandText = "ExpireFromMyTable"
                    lCmd.Parameters.AddWithValue("@myTableId", iMyTableId)
                    conn.Open()
                    lCmd.ExecuteNonQuery()
                    conn.Close()

                    //'Need to delete from 
                    gvMyTableMaintenance.DeleteRow(gvMyTableMaintenance.FocusedRowHandle)
                Catch ex As Exception
                    //'Handle Exception
                End Try
            End Using
        End Using
    End If
    e.Handled = True
End Sub

Private Sub gcMyTableMaintenance_EmbeddedNavigator_ButtonClick(ByVal sender As System.Object, ByVal e As DevExpress.XtraEditors.NavigatorButtonClickEventArgs) Handles gcMyTableMaintenance.EmbeddedNavigator.ButtonClick
    If e.Button.ButtonType = DevExpress.XtraEditors.NavigatorButtonType.Remove Then
        Dim iMyTableId As Int32 = 0

        iMyTableId = gvMyTableMaintenance.GetFocusedRowCellValue("id")

        Using conn As New SqlConnection(MyConnectionString)
            Using lCmd As New SqlCommand()
                Try
                    lCmd.Connection = conn
                    lCmd.CommandType = CommandType.StoredProcedure
                    lCmd.CommandText = "ExpireFromMyTable"
                    lCmd.Parameters.AddWithValue("@myTableId", iMyTableId)
                    conn.Open()
                    lCmd.ExecuteNonQuery()
                    conn.Close()

                    //'Need to delete from 
                    gvMyTableMaintenance.DeleteRow(gvMyTableMaintenance.FocusedRowHandle)
                Catch ex As Exception
                    //'Handle Exception
                End Try
            End Using
        End Using
    End If
    e.Handled = True
