    Hi Dimitar,
    I used table(e.g Employee) from database, added one column(e.g phone_number) in drop down list, in that table some employees don’t have phone number so,that column value is empty, In drop down list all values with check box gets added,even for empty phone number value only check box is shown
    On button click I want only those employees whose phone number is selected, but when i select check box which do not contains any value, i want that check box unselected automatically when i click on button.
    Or is there any way to hide that check box?
    Thank you,

    Hi abcd,

    The methods checkIndex, uncheckIndex, checkItem, uncheckItem and the event checkChange may be helpful to you. You can learn more about them in jqxDropDownList’s API Documentation.

    Hello,

    In JavaScript, the checked property sets or returns the checked state of a checkbox.

    This property reflects the HTML checked attribute.

    To check null in JavaScript, use triple equals operator(===) or Object.is() method. To find the difference between null and undefined, use the triple equality operator or Object.is() method.

    The methods checkIndex, uncheckIndex, checkItem, unchecked and the event checkChange may be helpful to you. You can learn more about them in jqxDropDownList’s API Documentation.

    Best Regards,
