are you trying to fill the DDL from database or trying to make your custom DDL.

one possibility is,Use the size attribute of the select element to specify the count of visible items.

XML

<select size="5">
    <option SELECTED />country1
    <option />country2
    <option />country3
    <option />country4
    <option />country5
    <option />country6
    <option />country7
    <option />country8
    <option />country9
    <option />country10
</select>

Solution 1

use the take method for the first 20 items on your data source, then bind it to the datasource of the combobox.
