Question

I am building a page with asp.net. I have a form with a table that contains TextBoxes and a submit button. When the form is submitted, I want to grab all the text that was entered into the TextBoxes and operate on them. To do this, I have the following method:

protected void Button1_Click(object sender, EventArgs e)
{
    System.Text.StringBuilder sb = new System.Text.StringBuilder();

    foreach (Control c in this.Controls)
    {
        if (c.GetType().Name == "TextBox")
        {
            TextBox tb = (TextBox)c;
            sb.AppendLine(tb.Text);
        }
    }
    Label1.Text = sb.ToString();
}

The problem with this is that the controls apparently doesn’t include any of my textboxes. When I iterate through the controls and print out their names, the only one I get is “site_master.” (I also tried Controls and Page.Controls instead of this.Controls).

Is there something wrong with my iterator? Is there another way in which I could iterate through all of the textboxes in the table or page? What is the best way to accomplish this?

Answer 1

Would it be too much to build a List<Textbox>, given you know all your textbox controls?

List<Textbox> txtBoxes = new List<Textbox>();
txtBoxes.Add(tb1);
txtBoxes.Add(tb2);
//etc..

Then you have a nice list to work with
