22 Feb 202218 minutes to read

You can dynamically change the Kanban columns by using the columns property.

In the below sample, you can dynamically change the allowToggle property at the particular column when you click on the button. You can also change the initially created columns to the new Kanban columns by using the columns property when you click on the button.

CSHTML

@Html.EJS().Button("particularColumn").Content("Enable Allow Toggle").Render()
@Html.EJS().Button("column").Content("Change Columns").Render()
@Html.EJS().Kanban("kanban").KeyField("Status").Created("onCreate").DataSource((IEnumerable<object>)ViewBag.data).Columns(col =>
            {
           col.HeaderText("To Do").KeyField("Open").Add();
           col.HeaderText("In Progress").KeyField("InProgress").Add();
           col.HeaderText("Testing").KeyField("Testing").Add();
           col.HeaderText("Done").KeyField("Close").Add();
       }).CardSettings(card => {
       card.ContentField("Summary").HeaderField("Id").ShowHeader(false);
       }).Render()

<script type="text/javascript">
    var kanbanObj;
    function onCreate() {
        kanbanObj = this;
    }
    document.getElementById('particularColumn').onclick = function () {
        kanbanObj.columns[1].allowToggle= true;
    };
    document.getElementById('column').onclick = function () {
        kanbanObj.columns = [
            { headerText: 'To Do', keyField: 'Open' },
            { headerText: 'Done', keyField: 'Close' }
        ]
    };
</script>
