Wizard and viewstate

[bhaizlett123]

I have a form with 3 wizard steps, and when i click the button to dynamically add text boxes, that works fine, but when i go to the next step and i click on add to add more text boxes, it automatically adds all the text boxes from the previous steps and then continues to add if i keep click on it.

How do i prevent that from happening.


private List<string> ControlsList
{
get
{
if (ViewState["controls"] == null)
{
ViewState["controls"] = new List<string>();
}
return (List<string>)ViewState["controls"];
}
}

private int NextID
{
get
{
return ControlsList.Count + 1;
}
}


protected override void LoadViewState(object savedState)
{

string section = Wizard1.ActiveStep.ID;
int sectionNum = Wizard1.ActiveStepIndex;

var control = Wizard1.ActiveStep.FindControl("Place" + sectionNum) as PlaceHolder;

base.LoadViewState(savedState);

int count = 0;
foreach (string txtID in ControlsList)
{
if (count == 0)
{
control.Controls.Add(new LiteralControl("<tr>"));
}
TextBox txt = new TextBox();
control.Controls.Add(new LiteralControl("<td>"));
txt.ID = txtID;
control.Controls.Add(txt);
control.Controls.Add(new LiteralControl("</td>"));

count = count + 1;
if (count == 3)
{
control.Controls.Add(new LiteralControl("</tr>"));
count = 0;
}

}
}


protected void AddControlButton_Click(object sender, EventArgs e)
{


string section = Wizard1.ActiveStep.ID;
int sectionNum = Wizard1.ActiveStepIndex;

var control = Wizard1.ActiveStep.FindControl("Place" + sectionNum) as PlaceHolder;

TextBox txt1 = new TextBox();
TextBox txt2 = new TextBox();
TextBox txt3 = new TextBox();


txt1.ID = section.ToString() + "Size" + NextID.ToString();
control.Controls.Add(new LiteralControl("<td>"));
control.Controls.Add(txt1);
control.Controls.Add(new LiteralControl("</td>"));
ControlsList.Add(txt1.ID);

txt2.ID = section.ToString() + "Description" + NextID.ToString();
control.Controls.Add(new LiteralControl("<td>"));
control.Controls.Add(txt2);
control.Controls.Add(new LiteralControl("</td>"));
ControlsList.Add(txt2.ID);

txt3.ID = section.ToString() + "Quantity" + NextID.ToString();
control.Controls.Add(new LiteralControl("<td>"));
control.Controls.Add(txt3);
control.Controls.Add(new LiteralControl("</td></tr>"));
ControlsList.Add(txt3.ID);
}
