Gridview更新

Question

当我以其他形式进行GridView数据更新然后数据更新但是当关闭此表单时，gridview数据刷新不会在C＃win-forms应用程序中自动响应 我的代码在这里：

private void button1_Click(object sender, EventArgs e)
{
    aCatagory=new tbl_Catagory();
    aContext = new RM_Inventory_DataContext();

    var product = (from p in aContext.tbl_Catagories
                   where p.CatagoriesID == Convert.ToDecimal(textBox1.Text) 
                   select p).Single();

    product.CatagoriesName = textBox2.Text;

    aContext.SubmitChanges();
    this.Close();
    AddCatagories addCatagories=new AddCatagories();
    addCatagories.GridView();
}


public void GridView()
{
    gridControl1.DataSource = new RM_PM_Inverntory_Management_System.RM_Inventory_DataContext().tbl_Catagories;
}

Answer 1

分配数据源后，您没有绑定gridview。

public void GridView()
{
gridControl1.DataSource = What ever Data Source You have
gridControl1.DataBind();
}
