從輸入類型文本框中檢索值的ASP.Net C＃請求

Question

因此，我們的小組在檢索輸入類型中輸入的值時遇到問題。 這是我們使用的代碼...

protected void Page_Load(object sender, EventArgs e)
{

    if (!Page.IsPostBack)
    {
        Session.Remove("clicks");
        i = 0;
    }
}
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
    int rowCount = 0;

    rowCount = Convert.ToInt32(Session["clicks"]);

    rowCount++;

    Session["clicks"] = rowCount;

    Literal1.Text = Literal1.Text + "PRODUCT: <input type='textbox' runat='server' id='textboxu" + i + "' value='" + GridView1.SelectedRow.Cells[1].Text + "' ></input> PRICE: <input type='textbox' runat='server' size='1' id='textboxe" + i + "' value='" + GridView1.SelectedRow.Cells[2].Text + "' ></input>QUANTITY:<input type='textbox' runat='server' size='1' id='textboxq" + i + "'></input>TOTAL:<input type='textbox' runat='server' size='3' id='total" + i + "' ></input><br>";
        i++;
}
protected void Button1_Click(object sender, EventArgs e)
{
    for (int check = 0; check <= i; check++)
    {
        double price = Convert.ToDouble(this.Request.Form["textboxe" + i + ".Value"]);
        double quantity = Convert.ToDouble(this.Request.Form["textboxq" + i + ".Value"]);
        double total = price * quantity;
        TextBox1.Text = Convert.ToString(total);
        //this.Request.Form["total" + i] = Convert.ToString(total);
    }
}

我們還需要從輸入類型中檢索答案。 我希望有人願意幫助我們...

Answer 1

這些不是服務器控件，因此您應該使用name屬性而不是id。

<input type='textbox' name='textboxu" + i + "' value='" + GridView1.SelectedRow.Cells[1].Text + "' ></input> 
...
double textboxu = Convert.ToDouble(this.Request.Form["textboxu" + i]);

Answer 2

為了獲得正確的答案，語法只有少許變化，請參見以下代碼段

 double price = Convert.ToDouble(Request.Form["textboxe" + i ]);
 double quantity = Convert.ToDouble(Request.Form["textboxq" + i]);
 double total = price * quantity;
 TextBox1.Text = Convert.ToString(total);

//you need to use only request.Form rather than .value attribute
 string szValue =  Request.Form["txt1"]
