使用c＃從asp.net中的文本框獲取內容

Question

我創建了兩個動態文本框。 像這樣...

protected void Button2_Click(object sender, EventArgs e)
    {
        TextBox1 = new TextBox();
        TextBox1.ID = "TextBox1";
        TextBox1.Style["Position"] = "Absolute";
        TextBox1.Style["Top"] = "25px";
        TextBox1.Style["Left"] = "100px";

        Panel1.Controls.Add(TextBox1);

        TextBox2 = new TextBox();
        TextBox2.ID = "TextBox2";
        TextBox2.Style["Position"] = "Absolute";
        TextBox2.Style["Top"] = "60px";
        TextBox2.Style["Left"] = "100px";
        Panel1.Controls.Add(TextBox2);
       //this.TextBox1.TextChanged += new System.EventHandler(this.TextBox_TextChanged);
       //this.TextBox2.TextChanged += new System.EventHandler(this.TextBox_TextChanged);

            }

now, i want to retrieve the content from the textboxes. please tell immediately how to do this .

Answer 1

您可以找到控件並獲取文本，例如以下示例：

string s = null;
TextBox control = FindControl("TextBox2") as TextBox;

if( control != null )
{
     // The content is here:
     s = control.Text;
}

如果您沒有使用MasterPage，則可以詢問請求：

string s = Request.Params["TextBox2"];

對不起，我沒有讀過第一個代碼（格式不正確）。 您已經為TextBoxChanged事件增值，在EventHandler中您可以使用“sender”：

TextBox control = sender as TextBox;
string s = null;
if(control != null)
   s = control.Text;
