獲取網格視圖中已選中行的textBox值

Question

我有一些問題，從文本框中獲取文本框，其中復選框已標記為檢查gridview。 當點擊按鈕時，它應該獲取prodID的已檢查行索引和來自文本框的文本數量：

protected void lbnConfirm_Click(object sender, EventArgs e)
    {
        string quantity = "" , prodID = "";
        foreach (RepeaterItem item in Repeater1.Items)
        {
            if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem)
            {
                Panel pnl = item.FindControl("pBody1") as Panel;
                GridView gv = pnl.FindControl("gvProduct") as GridView;
                foreach (GridViewRow gr in gv.Rows)
                {
                    CheckBox cb = (CheckBox)gr.Cells[0].FindControl("cbCheckRow");
                    if (cb.Checked)
                    {
                        //Get the productID which set as DataKeyNames for selected row index
                        prodID = gv.DataKeys[gr.RowIndex].Value.ToString();

                        var tbQuantity = gr.FindControl("tbQuantity") as TextBox;
                        if (tbQuantity != null)
                        {
                            quantity = tbQuantity.Text;
                        }
                        tempList.Add(prodID);
                    }  
                }
            }
        }
        for (int i = 0; i < tempList.Count; i++)
        {    
            //Testing
            lblTest.Text += tempList[i] + " " + quantity;
        }
    }

假設我得到prodID 1有50個單位，prodID 2有77個單位，prodID 3有90個單位。 當我循環通過tempList時，這是我應該得到的結果：

1 50units, 2 77units, 390units

但是，代碼不會單獨從每個產品的文本框中獲取數量。 這是我得到的結果：

1 90units, 2 90units, 3 90units

它只是簡單地獲取列表中的最后一個產品的數量。 我想知道有沒有辦法解決這個問題？ 提前致謝。

編輯部分：

 foreach (string key in tempList.Keys)
        {
            packagesNeeded = 1;
            unitQty = prodPackBLL.getUnitQtySPU(tempList[key]);
            lblTest.Text += key + " " + tempList[key];
            if (Convert.ToInt32(quantity) < (packagesNeeded * unitQty))
            {
                //Pop up message
                Page.ClientScript.RegisterStartupScript(GetType(), "UserDialogScript", "alert(\"Insufficient storage\");", true);
            }
        }

你可以這樣做：

        foreach (DataGridViewRow item in GV.Rows)
        {
            if (Convert.ToBoolean(item.Cells[0].Value) == true)
                //here you get the rowcell value :
                string val = item.Cells[1].Value.ToString();
                //If you want to convert to a textbox :
                TextBox textBox = (TextBox)item.Cells[1].Value;
        }

其中GV是gridview Id，復選框是0列，您可能想要得到的值是1列

Answer 2

這是因為您選擇了復選框，每行都會覆蓋變量“quantity”。 如果要存儲多個值，則需要使用List<string>存儲選中該復選框的每一行的數量。

像下面的東西。 注意：我還沒有測試過代碼。

protected void lbnConfirm_Click(object sender, EventArgs e)
{
    List<string> quantity = new List<string>(); 
    prodID = "";
    foreach (RepeaterItem item in Repeater1.Items)
    {
        if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem)
        {
            Panel pnl = item.FindControl("pBody1") as Panel;
            GridView gv = pnl.FindControl("gvProduct") as GridView;
            foreach (GridViewRow gr in gv.Rows)
            {
                CheckBox cb = (CheckBox)gr.Cells[0].FindControl("cbCheckRow");
                if (cb.Checked)
                {
                    //Get the productID which set as DataKeyNames for selected row index
                    prodID = gv.DataKeys[gr.RowIndex].Value.ToString();

                    var tbQuantity = gr.FindControl("tbQuantity") as TextBox;
                    if (tbQuantity != null)
                    {
                        quantity.Add(tbQuantity.Text);
                    }
                    tempList.Add(prodID);
                }  
            }
        }
    }
    for (int i = 0; i < tempList.Count; i++)
    {    
        //Testing
        lblTest.Text += tempList[i] + " " + quantity[i];
    }
}

您可以使用Dictionary將每個prodID與其對應的quantity配對。 試試這段代碼：

protected void lbnConfirm_Click(object sender, EventArgs e)
{
    Dictionary<string, string> tempList = new Dictionary<string, string>();
    string quantity = "", prodID = "";
    foreach (RepeaterItem item in Repeater1.Items)
    {
        if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem)
        {
            Panel pnl = item.FindControl("pBody1") as Panel;
            GridView gv = pnl.FindControl("gvProduct") as GridView;
            foreach (GridViewRow gr in gv.Rows)
            {
                CheckBox cb = (CheckBox)gr.Cells[0].FindControl("cbCheckRow");
                if (cb.Checked)
                {
                    //Get the productID which set as DataKeyNames for selected row index
                    prodID = gv.DataKeys[gr.RowIndex].Value.ToString();

                    var tbQuantity = gr.FindControl("tbQuantity") as TextBox;
                    if (tbQuantity != null)
                    {
                        quantity = tbQuantity.Text;
                    }
                    tempList.Add(prodID, quantity);
                }
            }
        }
    }

    foreach (string key in tempList.Keys)
    {
        packagesNeeded = 1;
        unitQty = prodPackBLL.getUnitQtySPU(key);
        lblTest.Text += key + " " + tempList[key];
        if (Convert.ToInt32(tempList[key]) < (packagesNeeded * unitQty))
        {
            //Pop up message
            Page.ClientScript.RegisterStartupScript(GetType(), "UserDialogScript", "alert(\"Insufficient storage\");", true);
        }
    } 
}

根據上面的例子， tempList["1"]將產生"50" ， tempList["2"]將產生"77" ，而tempList["3"]將產生"90" 。
