suppose textbox id is txt1: 

protected void Button2_Click(object sender, EventArgs e)
  {
    //from page
    TextBox tx = (TextBox)Page.FindControl("txt1");
    Response.Write(tx.Text.ToString());
 
    //from panel
    TextBox txt = (TextBox)Panel1.FindControl("txt1");
    Response.Write(txt.Text.ToString());
  }

HI

If you are using dynamically created controls, you have to create them in Page_PreInit for the page to properly process the events and viewstate. This will help you to write code like this for getting textbox values:

TextBox tb = FindControl(BaseChildSectionName + i.ToString()) As TextBox;
xtw.WriteString(tb.Text);

If you are not interested in recreating your textboxes, then you will have to get the textbox value directly from the Form parameters like this:

xtw.WriteString(Request.Form[BaseChildSectionName + i.ToString()]);


(or)

try this

protected void btnDoStuff_click(Object sender, EventArgs args)
{
   TextBox txtBox = (TextBox) pnlDynamicButtons.FindControl("txtBox1");
}

hi,

Like this you can get the data from dynamic generated text box

protected void Page_Load(object sender, EventArgs e) 
   { 
     if (IsPostBack) 
     { 
       if (TextBox1.Text != string.Empty) 
       { 
         int count = 0; 
         int.TryParse(TextBox1.Text, out count); 
          
         for (int i = 0; i < count; i++) 
         { 
           TextBox txt = new TextBox(); 
           txt.ID = "dynamicText" + i.ToString(); 
           if (PlaceHolder1.FindControl(txt.ID) != null) 
           { 
             PlaceHolder1.Controls.Add(txt); 
           } 
         } 
       } 
     } 
      
   } 
   protected void Button1_Click(object sender, EventArgs e) 
   { 
     if (TextBox1.Text != string.Empty) 
     { 
       int count=0; 
       int.TryParse(TextBox1.Text,out count); 
       for (int i = 0; i < count; i++) 
       { 
         TextBox txt = new TextBox(); 
         txt.ID = "dynamicText" + i.ToString(); 
         PlaceHolder1.Controls.Add(txt); 
       } 
     } 
   }

Hope this will help you
