如何在Visual Studio表单中刷新数据gridview? [英] How to refresh data gridview in visual studio form?

问题描述

我有一个带有网格视图数据和数据库数据的表格.通过查询，我可以通过按钮将INSERT INTO从一个表运行到另一个表.我想在运行过程时，还使用新的导入数据重置/更新/刷新gridview.

对于信息，我尝试了一些方法，例如me.gridview.refresh()或update()，但是什么也没有.也许我也用错了这种方法.

Hi,

I have a form with gridview data with database data. With query I run INSERT INTO from one table into another, with button. I would like when I run procedure, also reset/update/refresh gridview with new import data.

For info, I have try with some methods, such as me.gridview.refresh() or update(), but nothing. Maybe I have also using this methods wrong.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim TEST = New WindowsApplication1.IdisDataSetTableAdapters.QueriesTableAdapter
        TEST.InsertQuery()
        
End Sub

推荐答案

如果将gridview绑定到BindingSource [

If you bind your gridview to a BindingSource[^] and your DataSource to the BindingSource, you might be able to use the BindingSource.ResetBindings or ResetcurrentItem or ResetItem methods, although the BindingSource should do this automatically.

我认为您必须将数据源重新绑定到GridView.但是我无法在您的事件处理程序中找到任何与Gridview相关的代码.

最好的问候，

I think you''ll have to rebind the datasource to the GridView. I can''t locate any gridview related code in your event handler though.
