Handle the selectedIndexChanged event using JavaScript and try something like this.

JavaScript

function onSelectedIndexChanged()
{
   if($("#mySelect").val() == "OTHER")
   {
     $("#textbox").show();
   }
}

Solution 2

add items to your dropdownlist or combobox

C#

cmbname.Items.AddRange(new object[] {
            "x",
            "y",
            "z",
            "other"});

make a textbox beside dropdownlist and keep textbox invisible

C#

textBox1.Visible = false;

use below code in SelectedIndexChanged event of combobox

C#

if (cmbname.Text == "other")
{
textBox1.Visible = true;
}

Yep, that is how I would do it.
(Except I would use a case statement).
