asp.net/ascx

The attached codes came from ascx code behind.
My issue is I don't know how to create public class in get/set
with the dynamic city/state pairs. The codes basically have dropdown from 1 to 25
and value is used to determine how many pairs of city/state textbox will be shown up.
 
CityTextBox.ID = "City_" + i;
StateTextBox.ID = "State_" + i;

I will need to get get/set like
public int TotalLocation { get { return int.Parse(DdlTotalLocation.Text); } }

Please help me and see you can finish my rest of the tasks.

Thanks,

500 pts for working codes.

protected void DdlTotalLocation_SelectedIndexChanged(object sender, EventArgs e)
    {
        int TotalLocationCount = int.Parse(DdlTotalLocation.SelectedValue);
        if (TotalLocationCount >= 1)
        {
            LblCityStateList.Visible = true;
            for (int i = 0; i < TotalLocationCount; i++)
            {
                //TextBox CityTextBox = new TextBox();
                Obout.Interface.OboutTextBox CityTextBox = new Obout.Interface.OboutTextBox();
                CityTextBox.ID = "City_" + i;
                CityTextBox.Width = 170;
                CityTextBox.TabIndex = 1;
                //TextBox StateTextBox = new TextBox();
                Obout.Interface.OboutTextBox StateTextBox = new Obout.Interface.OboutTextBox();
                StateTextBox.ID = "State_" + i;
                StateTextBox.Width = 100;
                StateTextBox.TabIndex = 2;
                DivSelectCity.Controls.Add(CityTextBox);
                DivSelectState.Controls.Add(StateTextBox);
            }
        }
        else
            LblCityStateList.Visible = false;
    }
    //=====================================================================================
    public int TotalLocation { get { return int.Parse(DdlTotalLocation.Text); } }
