c# - 我如何从 Rows.count 循环中按 ID 获取项目

Question

我想做的是，我想从 gridview 更新任何选中项目的状态。

我的错误:

Server Error in '/' Application.

Input string was not in a correct format.

    protected void btnSubmit_Click(object sender, EventArgs e)
    {
        for (int i = 0; i < GridView1.Rows.Count; i++)
        {
            DropDownList drpDwnStat = (DropDownList)GridView1.Rows[i].FindControl("drpDwnStatus");
            CheckBox chkBox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
            

            using (SPSite site = new SPSite(SPContext.Current.Web.Url))
            {
                using (SPWeb web = site.OpenWeb())
                {
                    SPList list = web.Lists.TryGetList("List");
                    if (list != null)
                    {
                        if (chkBox.Checked == true)
                            {
                                GridViewRow row = (GridViewRow)chkBox.NamingContainer;
                                int index = row.RowIndex;

                                SPListItem newStat = list.Items.GetItemById(int.Parse(GridView1.Rows[index].Cells[1].Text));
                                {
                                    web.AllowUnsafeUpdates = true;
                                    newStat["Status"] = drpDwnStat.SelectedItem.Text;

                                    newStat.Update();
                                    web.AllowUnsafeUpdates = false;
                                }
                            }
                    }
                }
            }
        }
    }

Answer 1

这一行:

SPListItem newStat = list.Items.GetItemById(int.Parse(GridView1.Rows[index].Cells[1].Text))

您似乎从 Cells[1] 获得了 int 值。但是根据您的图片，int 文本 ID 位于 Cells[0](即第一列在行中)。

Cells[1] 引用第二列:

Diryas
Soban
Attiq
test

Cells[0] 引用第一列:

3
4
5
8
