将一行添加到 DGV 链接到表格的 DGV 中
原标题:adding a row to a DGV bound to a table

我用下面的表格在 WinForm 上的 DataGridView 上添加一个表格:

    void PopulateGridView() {
        conn = new SqlConnection(ConfigurationManager.ConnectionStrings["IMS"].ConnectionString);
        myAdapt = new SqlDataAdapter("SELECT * FROM FrontDesk.dbo.tb_xxx", conn);
        mySet = new DataSet();
        myAdapt.Fill(mySet, "AvailableValues");
        myTable = mySet.Tables["AvailableValues"];

        this.uxChargeBackDataGridView.DataSource = myTable;
        this.uxChargeBackDataGridView.Columns["RefKey"].Visible = false; 
    }

表格中有5行,只有2个字段 - 字段 < code> RefKey 隐藏在DGV之外,是基础表格的主要关键。

为何不做以下工作? Add 似乎是用于添加行的 DGV 行收藏的属性 :

    private void button1_Click(object sender, EventArgs e)
    {
        uxChargeBackDataGridView.Rows.Add(6, "dre");
    }
最佳回答

由于网格使用数据表作为源,您必须在表格中添加行。网格 应自动 反映:

DataTable table = (DataTable)uxChargeBackDataGridView.DataSource;
DataRow row = table.NewRow();
row[0] = 6;
row[1] = "dre";
table.Rows.Add(row);

在数据表格上使用 NewRow () 函数来获取数据列表使用的图案的“DataRow”对象。

如果您将您的 mySet my Table 变量移到窗体级别范围, 您就不必创建 task.Rows.Add(row) > 引用; my Table 变量, 这样您就可以直接使用 my Table.Rows.Add(row) > ;
