this.dataGridView1.Refresh（）;对我不起作用？ [英] this.dataGridView1.Refresh(); Doesn't work for me?

问题描述

我有一个带有datagridview的WinForm ......每次按下一个按钮时，我都会有一个按钮列（更新，添加），行更新/添加。

i想要重新加载数据网格或者在从另一个表单添加或更新之后刷新它，以及在我有DGridview的同一个表单中...

i尝试

 此 .dataGridView1.Refresh（）; 

但它不起作用



剩下的代码：

 尝试 
 {
 
 SqlConnection conn =  new  SqlConnection（   Server = localhost; database = tailoringmng; integrated Security = true）; 
 SqlCommand cmd =  new  SqlCommand（  undonetask ，康涅狄格州）; 
 cmd.CommandType = CommandType.StoredProcedure; 
 SqlDataAdapter da =  new  SqlDataAdapter（cmd）; 
 
  if （conn ==  null && conn.State = = ConnectionState.Closed）
 {
 conn.Open（）; 
} 
 dt =  new  DataTable（  myTable的）; 
 da.Fill（dt）; 
 
 dgridstatus.DataSource = dt.DefaultView; 
 
 conn.Close（）;
