It should be an easy task unless there are more conditions.

You may code like -

C# Approach

On dropdownlist SelectedIndexChanged
(Make sure that you have set property AutoPostBack="True" for that dropdownlist)

C#

If(drp.SelectedValue=="first")
{
   txt1.Visible=false;
   txt2.Visible=true;
   //... and son on
}
else if(drp.SelectedValue=="second")
{
  txt2.Visible=false;
  txt1.Visible=true;
  //... and so on
}

Javascript Approach
aspx snippet

ASP.NET

<asp:DropDownList  ID="drp" runat="server" onchange="HideTextBoxes();"

Javascript snippet

JavaScript

<script>

function HideTextBoxes()
        {
             var selectedvalue= document.getElementById("<%=drp.ClientID%>").value;
           
             if(selectedvalue == "first")
             {
                 document.getElementById("<%=txt1.ClientID%>").style.display = 'none';
                 document.getElementById("<%=txt2.ClientID%>").style.display = '';//....and son....
              
             }
             else if(selectedvalue == "second")
             {
                document.getElementById("<%=txt2.ClientID%>").style.display = 'none';
                document.getElementById("<%=txt1.ClientID%>").style.display = '';// ... and son on
               
             }
        }

 </script>

try this...

XML

<select name="type">
  <option value="plane">Plane</option>
  <option value="car">Car</option>
</select>
<input class="hideme" type="text" name="name">

JavaScript

$('select').change(function(){
if($(this).val()=== "car")
$('.hideme').show();
else
    $('.hideme').hide();
}).change();
