Maximum call stack size exceeded - When Trying to Empty ComboBox DataSource

[Alexandre]

Hello,

I am trying to empty the datasource of a combobox via javascript, but at the momento I try to do it I get the error Maximum call stack size exceeded. 

I need to empty the datasource to reload it with a new one, but something is not working well with the code.

This is the sample code:

(Empty the DataSource) document.getElementById("lstEmpenhos").ej2_instances[0].dataSource = []; (Fill the DataSource with another content)

document.getElementById("lstEmpenhos").ej2_instances[0].dataSource = EmpenhoList;

After running that code, the dropdown arrow on the combobox turns into an spinning wheel and I get the error mentioned above.

 

Is there a solution for this problem?

Regards,

Alexandre

Hi Alexandre,

Your reported issue can be resolved by calling dataBind method after removing and adding the dataSource to the control. please check the code below,

Code snippet:

<div class="control-wrapper">

    <div id="default" style='padding-top:75px;'>

        <ejs-combobox id="games" dataSource="@ViewBag.data" placeholder="Select a game" popupHeight="220px">

        </ejs-combobox>

    </div>

    <ejs-button id="targetButton" content="Change"></ejs-button>

</div>

<script>

    window.onload = function () {

        document.getElementById('targetButton').onclick = function () {

           var comboObj = document.getElementById('games').ej2_instances[0];

           comboObj.dataSource = [];

           comboObj.dataBind();

           comboObj.dataSource =  ["Golf", "Gymnastics", "Hockey", "Tennis"];

           comboObj.dataBind();

        }

    }

</script>
