推荐答案

您的问题尚不完全清楚，但据我了解，您可能需要处理DataGridView.DefaultValuesNeeded [

Your question is not entirely clear but from what I can understand you may need to handle the DataGridView.DefaultValuesNeeded[^] event.

您的问题不是很清楚，但我认为您希望将Grid与从数据库获得的默认值绑定.
为此，您必须将数据源分配给DataGrid的bind属性.点击此链接以获取更多参考.

Your question is not that much clear but what I think is you want to Bind the Grid with the default values you get from database.
For that you have to assign your Data source to the DataGrid''s bind property. Follow this link for more reference.

If you describe your question clearly the more you will drove towards solution. So be precise in description of your question.

首先，甘道夫(Gandalf)感谢您的宝贵时间.

因此，我有一个datagridview，它从访问的一个表中填充.
在我的datagridview中，我想显示7个字段. (我总共有9个字段)
在其中一个中，我要放置一个在保存之前计算的数字，另一个中我要放置系统日期和时间..

我保存的datagridview包含此代码

First of all Gandalf Thanks for your time.

So I have a datagridview that fill from one table from access.
In my datagridview i want to show 7 of me fields. (Totaly i have 9 fields)
In one of them i want to put a number that calculate before save and the other put the system date and time..

My datagridview for save has this code

Private Sub Movement_roller_DBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Movement_roller_DBindingNavigatorSaveItem.Click
    Me.Validate()
    Me.Movement_roller_DBindingSource.EndEdit()
    Me.TableAdapterManager.UpdateAll(Me.RollerDataSet)
End Sub
