c# bug on button click

[shhntl]

hi,
I m very new here. So my base is not so strong and I have a small prob
I am trying to add a textbox at runtime on the click of a button.
So every time the button is clicked a new textbox has to be generated without effecting the previous textboxes that are already created.

here is my code
public partial class enteriquestions : System.Web.UI.Page
{
int rowcount;
public TableRow tr;
TableCell td1,td2;
TextBox tb1;
Label label1;

protected void Page_Load(object sender, EventArgs e)
{
if(Page.IsPostBack == false)
rowcount = 1;
createrow();
Page.Focus();

}
protected void Button2_Click(object sender, EventArgs e)
{
rowcount++;
createrow();
}
public void createrow()
{
tr = new TableRow();
td1 = new TableCell();
label1 = new Label();
label1.ID = "lbl" + rowcount.ToString();
label1.Text = "Enter Question" + rowcount;
td2 = new TableCell();
tb1 = new TextBox();
tb1.ID = "txtbox" + rowcount.ToString();
tb1.Width = 700;
td1.Controls.Add(label1);
td2.Controls.Add(tb1);
tr.Cells.Add(td1);
tr.Cells.Add(td2);
Table1.Rows.Add(tr);
tb1.Focus();
}

The problem that i am having is everytime the button is clicked the rowcount is reinitialized to 0. How do i solve this to increament the row count.
Please help me

The value won't increment unless you store it somewhere. I remember once storing it textbox that that wasn't visible. HTH.

Hello

i a web application when ever the page is post back you have to maintain the view state of some variables ,so you variable is restoring to initial value on each click,

try to maintain the view state of the variable so that it always store the latest updated value ,to do this you have many ways(sessions ,applications,some times static fields) try to choose your best way

Good Luck

thanks very much for your help. IT was really help ful.
I stored the rowcount in the session and now the rowcount is increamenting in the way that i wished it to do.
But now on every button click as the page is refreshed the previous textboxes disappears and only the new one in displayed.
what do I do so that the previous rows remain and the new row is generated.
Plz help me out to finish this code.

You will need to store and restore those textboxes in some sort of persistant collection.
