• i think $("#txtName").autoplete() is sufficient no need for keyDown – Sandip Pingle Commented Sep 15, 2014 at 11:08
• What does the MVC action look like? – Ashley Medway Commented Sep 15, 2014 at 11:08
• You just want it to begin searching on the first keystroke? Try using minLength: 1. – DevlshOne Commented Sep 15, 2014 at 11:08

You do not need the keyDown event otherwise you are rebinding the autoplete on every keydown.

$("#txtName").autoplete({
    source: '@Url.Action("GetAllName", "Home")',
    select: function (event, ui) {
        $("#txtName").val(ui.item.value);
        return false;
    }
});

To show all results when one character is entered add minLength: 1

If what you want is to have all the items displayed when the textbox has focus then this is what you are looking for: https://stackoverflow./a/4604300/1398425

If you just want it to begin searching on the first keystroke, try using minLength: 1:

$("#txtName").autoplete({
    source: '@Url.Action("GetAllName", "Home")',
    minLength: 1,
    select: function (event, ui) {
        $("#txtName").val(ui.item.value);
        return false;
    }
});
