Question

我正在尝试从我的带有一些数据的radGrid中插入数据到我的sql。在我的rad网格中我也有一个复选框列，所以我希望在我的数据库中插入已选中的行。我使用下面的代码，但给我这个错误：错误30＆＃39; Telerik.Web.UI.RadGrid＆＃39;不包含＆＃39;行＆＃39;的定义没有延伸方法＆＃39;行＆＃39;接受类型为＃Telerik.Web.UI.RadGrid＆＃39;的第一个参数。可以找到（你错过了使用指令或汇编引用吗？）任何想法我在哪里做错了???

  protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            this.BindGrid();
        }
    }

    private void BindGrid()
    {
        string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
        using (SqlConnection con = new SqlConnection(constr))
        {
            using (SqlCommand cmd = new SqlCommand("SELECT [ReportId], [Report], [IsSelected] FROM Hobbies"))
            {
                using (SqlDataAdapter sda = new SqlDataAdapter())
                {
                    cmd.Connection = con;
                    sda.SelectCommand = cmd;
                    using (DataTable dt = new DataTable())
                    {
                        sda.Fill(dt);
                        RadGrid1.DataSource = dt;
                        RadGrid1.DataBind();
                    }

要访问行，请遍历其DataItems。有关Accessing Cells and Rows

的更多信息

protected void Button1_Click(object sender, EventArgs e)
{
    foreach (GridDataItem row in RadGrid1.Items)
    {
        string rowValue = row["ColumnUniqueName"].Text;
    }
}

更好的方法是创建一个几乎没有参数来更新SQL数据库的方法。完成后，在RadGrid（Differences Between ItemCreated and ItemDataBound）的ItemDataBound事件中调用它。在这种情况下，您可以访问行，其单元格，获取必要的值并逐行更新数据库。

bool IsClicked = false;
protected void Button1_Click(object sender, EventArgs e)
{
    IsClicked = true;
    RadGrid1.Rebind();
}

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (IsClicked && e.Item is GridDataItem)
    {
        updateDatabase(((GridDataItem)e.Item)["ColumnUniqueName"].Text);
    }
}

protected void updateDatabase(string field)
{
    // update SQL
}

使用复选框从RadGrid在sql中插入数据
