In your Button1_Click event, use the Response.Redirect method to send people to the appropriate page.

Following can be helpful for you.

protected void Button1_Click(object sender, EventArgs e)
{
    string sel_val = DropDownList1.SelectedValue; // use sel_val to apply if, else logic to redirect to
    // some possible examples
    if (sel_val != "-1") // as SelectedValue is string
    {
        // assuming there is staff.aspx, and you want to redirect to that page on selecting staff, this is just an example
        Response.Redirect(sel_val + ".aspx"); // use this to redirect to required page
    }

}

Also change aspx code like this.Note i have changed OnClick from onclick.

<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Click to Proceed" />

if (DropDownList1.SelectedValue == "staff") { Response.Redirect("Logs.aspx"); } I did like this but it failed to redirect @Arindam Nayak

Are you able to debug and see any error? It should work, and you are doing it correctly.

I dont get any error.. When i click the button its still in the same page :-( @Arindam Nayak

You can remove this onselectedindexchanged="DropDownList1_SelectedIndexChanged" if you don't need select event, and does that page refresh? i mean does it postback?
