How are you adding dynamic textboxes?
What you have to do is stop that code execution on the click of the button.

Hi sweetSteal,
According to your description, I have made a sample here.You could just package the function to create textbox then you could delete the textbox in the panel when you submit the data . Here is the demo. I hope it could help you.
aspx:
<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div class="form-group"> <asp:Label ID="NumberOfFilesLabel" runat="server" Text="Number of Textbox" CssClass="control-label col-md-2" /> <div class="col-md-10"> <asp:TextBox ID="NumberOfFilesValue" runat="server" OnTextChanged="NumberOfFilesValue_TextChanged" AutoPostBack="true" CssClass="form-control" style="width:50px" /> </div> </div> <asp:Panel ID="FilenamePlaceholder" runat="server" /> <hr /> <div class="form-group"> <div class="col-md-offset-2 col-md-10"> <asp:Button ID="BatchSubmit" runat="server" Text="Destroy" OnClick="BatchSubmit_Click" CssClass="btn btn-default" /> </div> </div> </form> </body> </html>
aspx.cs:
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; namespace Class { public partial class article : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { List<string> keys = Request.Form.AllKeys.Where(key => key.Contains("textbox")).ToList(); foreach (string key in keys) { addrow tbRow = new addrow(); FilenamePlaceholder.Controls.Add(tbRow.NewRow(key)); } } protected void NumberOfFilesValue_TextChanged(object sender, EventArgs e) { FilenamePlaceholder.Controls.Clear(); int file_count = Convert.ToInt16(NumberOfFilesValue.Text); string pre = "text"; for (int i = 1; i <= file_count; i++) { string control_text = pre + i.ToString(); addrow tbRow = new addrow(); FilenamePlaceholder.Controls.Add(tbRow.NewRow(control_text)); } } protected void BatchSubmit_Click(object sender, EventArgs e) { // loop for all textbox then submit the data finally delete them FilenamePlaceholder.Controls.Clear(); } } public class addrow { public HtmlGenericControl NewRow(string ControlText) { HtmlGenericControl main_div = new HtmlGenericControl("div"); //main div main_div.Attributes["class"] = "form-group"; Label l = new Label { ID = ControlText.Replace(" ", String.Empty) + "Label", Text = ControlText, }; main_div.Controls.Add(l); //add label to main div HtmlGenericControl value_div = new HtmlGenericControl("div"); //secondary div value_div.Attributes["class"] = "col-md-10"; TextBox tb = new TextBox { ID = ControlText.Replace(" ", String.Empty) + "Value", CssClass = "form-control" }; value_div.Controls.Add(tb); main_div.Controls.Add(value_div); //add secondary div to main div return main_div; } } }
It shows as :
