I need to generate the textboes of present product and previous. Both should appear in my place holder.How will i Do it. Kindly Help.

C#

protected void Button1_Click(object sender, EventArgs e)
{
 
{
if (txtQuantity.Text != "")
{
for (int i = 0; i < Convert.ToInt16(txtQuantity.Text); i++)
{


Label la = new Label();
la.Text = ddlProductName.SelectedItem.Value + i.ToString();
la.ID = "abc" + i.ToString();
   
PlaceHolder1.Controls.Add(la);
 
//la = FindControl(String.Format(i)) as Label;
 

 

TextBox txtbox = new TextBox();

Solution 1

hope so you are missing to add the textbox control to PlaceHolder
 
TextBox txtbox = new TextBox();
txtbox.Text = "Textbox - " + i.ToString();
 
 
PlaceHolder1.Controls.Add(txtbox);

And see for more help

PlaceHolder1.Controls.Add(new LiteralControl("<input id='txt' name='Textbox" + i + "'type='text' />"));
PlaceHolder1.Controls.Add(new LiteralControl("
"));
This code generating Textboxes. My problem is how to see the prevous textboes before postback.

I don't think so. Your generate texbox code is TextBox txtbox = new TextBox();
txtbox.Text = "Textbox - " + i.ToString();
and you have add this textbox name
