I have a dropdown list with values tied to a database.
I have a textbox that i need to populate with a value based on the selection made in the dropdown.

The table that has all of the selections in the dropdown is 2 columns. 1 is what is in the dropdown, the other has the corresponding value that needs to appear in the textbox when a selection is made.

What is the best way to do this without posting back?

Add this scripts in your <head> section

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js">
</script>

<script type="text/javascript">
    $(document).ready(function () {
        //We are binding onchange event using jQuery built-in change event
        $('#ddlList1').change(function () {
            //get selected value and check if subject is selected else show alert box
            var SelectedValue = $("#ddlList1").val();
            if (SelectedValue > 0) {
                //get selected text and set to label
                var SelectedText = $("#ddlList1 option:selected").text();
                lblSelectedText.innerHTML = SelectedText;
                //set selected value to textbox
            $('#txtFirstName').val(SelectedValue);
            
            //if you want to show the text then uncomment below line      
            //$('#txtFirstName').val(SelectedText);
               
            } else {
                //reset textbox values
            $('#txtFirstName').val('');
               
            }
        });
    });
</script>

and make your dropdown ClientIDMode='Static'

 <asp:DropDownList ID="ddlList1" runat="server" ClientIDMode="Static">

I probably should have mentioned this earlier but both controls are in a repeater called Repeater2 which is inside a GridView called GridView1. How would I make sure the correct controls are submitted to the script?
