Question

*I have 2 aspx pages default1.aspx and default2.aspx. I created a drop down list in default1.aspx. I want to retrieve the selected value of drop down list and set the label value in my default2.aspx page after i click submit button in default1.aspx page.*

Answer 1

  protected void Button1_Click(object sender, EventArgs e)
  {
  Session["Value"] = DropDowlList.SelecetedValue;
  Response.Redirect("default2.aspx ");
  }

In default2.aspx acess that Session like this.

if it is integer

 int value=Convert.ToInt32(Session["Value"]);

if it is string

string value=Convert.ToString(Session["Value"]);
