How to clear the selected checkboxes inside the dropdownlist control

Hi Support:

We want to have a button that when is clicked will reset the selected checkboxes inside the dropdownlist asp.net core control.

This is the dropdownlist definition:

<ej-drop-down-list id="states" name="states" show-checkbox="true" datasource="@((IEnumerable<State>)ViewData["States"])">

<e-drop-down-list-fields text="Name" value="ID" />

</ej-drop-down-list>

Thanks in advanced

David

Hi David,

Thanks for Contacting Syncfusion support.

You can unselect the selected items by using unCheckAll() public method in Dropdown List. Please refer to the below code snippet:

<code>

function btnclick(args) {

target = $('#skillsets').data("ejDropDownList");

target.unCheckAll();

}

</code>

Refer to the online sample browser sample link: http://aspnetcore.syncfusion.com/dropdownlist/checkbox
