How to refresh a web page in asp.net

Question

In my code i added dynamically some text-boxes and labels.
Then by dropdownlist event i want to refresh the page in a way that all the added text-boxes and labels will remove from aspx

how can it be done?

Answer 1

1. Add AutoPostBack="True" for the DropDownList

2. Add an event to DropDownList for SelectedIndexChange
   OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged"

3. In the Code-Behind file :

   private void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
   {
       if (DropDownList1.SelectedIndex == 0)
       {
           Label1.Visible = false;
       }
       else
       {
           Label2.Visible = false;
       }
   }
   

Answer 2

I assume you're using C#.

You can redirect to the current page by doing this from your code-behind:

Response.Redirect(HttpContext.Current.Request.Url.AbsoluteUri);
