<H3> I tried using find controls it is always returning null </H3>



protected void btAddSection_Click(object sender, EventArgs e)
{
    string path = "C:/Users/emahou1/Desktop/testfolder";
    if (cbIsLink.Checked == true)
    {
        if (fuTitleLink.HasFile)
        {
            // it is other section has nothing to do with the 12 input tags
        }
        else
        {
            // get the link path from the text box and save it ??   
        }
    }
    else
    {
        for (int i = 0; i < Request.Files.Count; i++  )
        {
            string text = "";
            for (int t = 1; t <= 5; t++)
            {
                TextBox tb = FindControl("fuTitle" + t.ToString()) as TextBox;
                if (tb != null) text += tb.Text;
            }
            if (Request.Files[i].FileName.ToString() != "")
            {

               // here i will collect the files and the textbox values to submit them to database
            }
        }
    }
}

我有12个输入选项卡，我将用于将文件上传到服务器，我已经循环输入控件来获取文件，但这些文本框我想循环遍历它们所以我可以捕获用户输入的文本，并使用该文本重命名正在上传的每个文件....

如何在面板中使用FindControl。像这样的东西

for (int t = 1; t <= 5; t++)
{
    TextBox tb = pnlDocUpload.FindControl("fuTitle" + t.ToString()) as TextBox;
    if (tb != null) text += tb.Text + "<br>";
}

我需要循环遍历TextBox以使用代码隐藏在asp.net c＃中获取文本值？
