問題描述

我在我的Web應用程序中使用網格視圖控件。我的網格視圖看起來像這樣。

在此輸入圖像描述

單擊“添加”按鈕時，我得到的結果如下所示。 在此輸入圖像描述

但我的預期結果就是這個......我的錯誤在哪里？ 我該怎么辦？ 在此輸入圖像描述

這是我的編碼..

2 個解決方案

解決方案1
 2 已采納  2013-12-04 13:10:17

請在下方進行更改....

1）在addnew（）函數更改下面的代碼行： 

dtCurrentTable.Rows[i - 1]["Item Description"] = box3.Text;
dtCurrentTable.Rows[i - 1]["Item Description"] = box4.Text;
dtCurrentTable.Rows[i - 1]["Item Description"] = box5.Text;
dtCurrentTable.Rows[i - 1]["Item Description"] = box6.Text;

更改代碼如下： 

dtCurrentTable.Rows[i - 1]["Item Description"] = box3.Text + "," + box4.Text + "," + box5.Text + "," + box6.Text;

同樣的邏輯適用於訂單數量，UOM，費率，貨幣和金額字段/控件的商店價值

2）在SetPreviousData（）函數下面改變代碼行： 

box3.Text = dt.Rows[i]["Item Description"].ToString();

更改代碼如下： 

if(Convert.ToString(dt.Rows[i]["Item Description"]).Trim() != "")
{
string[] strDesc = Convert.ToString(dt.Rows[i]["Item Description"]).Trim().Split(',');
box3.Text = strDesc[0].ToString();
box4.Text = strDesc[1].ToString();
box5.Text = strDesc[2].ToString();
box6.Text = strDesc[3].ToString();
}

同樣的邏輯適用於訂單數量，UOM，費率，貨幣和金額字段/控件的商店價值

在addnewrow（）函數中替換下面的代碼： 

for (int i = 1; i <= dtCurrentTable.Rows.Count; i++)
        {
            DropDownList box2 = (DropDownList)GridView1.Rows[0].Cells[1].FindControl("DropDownList1");
            box2.DataSource = SIMBL.ShowSalesOrderArticleNumberInfo();
            box2.DataTextField = "Port_Number";
            box2.DataValueField = "Description";
            box2.DataBind();
            box2.Items.Insert(0, " ");


        }

用以下代碼行替換上面的代碼...... 

for (int i = 0; i <= dtCurrentTable.Rows.Count; i++)
        {
            DropDownList box2 = (DropDownList)GridView1.Rows[i].Cells[1].FindControl("DropDownList1");
            box2.DataSource = SIMBL.ShowSalesOrderArticleNumberInfo();
            box2.DataTextField = "Port_Number";
            box2.DataValueField = "Description";
            box2.DataBind();
            box2.Items.Insert(0, " ");

    DropDownList box12 = (DropDownList)GridView1.Rows[i].Cells[4].FindControl("DropDownList3");
        box12.DataSource = SIMBL.ShowUnitItemInfo();
        box12.DataTextField = "Name";
        box12.DataValueField = "Symbol";
        box12.DataBind();
        box12.Items.Insert(0, " ");

        DropDownList box13 = (DropDownList)GridView1.Rows[i].Cells[4].FindControl("DropDownList4");
        box13.DataSource = SIMBL.ShowUnitItemInfo();
        box13.DataTextField = "Name";
        box13.DataValueField = "Symbol";
        box13.DataBind();
        box13.Items.Insert(0, " ");

        DropDownList box14 = (DropDownList)GridView1.Rows[i].Cells[4].FindControl("DropDownList5");
        box14.DataSource = SIMBL.ShowUnitItemInfo();
        box14.DataTextField = "Name";
        box14.DataValueField = "Symbol";
        box14.DataBind();
        box14.Items.Insert(0, " ");

}
