text_id_1 = document.getElementById("text_id_1");
    text_id_2 = document.getElementById("text_id_2");
    text_id_2.value = text_id_1.value;

Solution 1

In SelectedIndexChanged event of dropdown1, set the SelectedIndex of dropdown2 to SelectedIndex of dropdown1.

C#

void dropdown1_SelectedIndexChanged(object sender, EventArgs e)
        {            
            dropdown2.SelectedIndex = dropdown1.SelectedIndex;
        }

Try:

JavaScript

function SelectCorrespondinValue()
{
var dropdownlisttwo = document.getElementById("DropDownListTwo");
var e = document.getElementById("dropdownlistone");
var selectedValue = e.options[e.selectedIndex].text;

for(var i = 0; i < dropdownlisttwo.length -1; i++)
{
    if(selectedValue == dropdownlisttwo.options[i].text)
    { 
        dropdownlisttwo.selectedIndex = i;
    }
}
}

Call this function on "change" event of your first DropdownList. Let me know if it helps.
