How to enable or disable editing columns in ASP.NET MVC Web Forms Gantt?

In Gantt, specific columns can be made “non-editable” or read-only, by using the beginEdit client-side event, with column index from event argument values.

The following code example explains how you can make a column as non-editable or read-only.

ASPX

<ej:Gantt ID="Gantt" runat="server” BeginEdit="beginEdit”>
</ej:Gantt>
<script type="text/javascript">
function beginEdit(args) {
         if (this.getColumns()[args.columnIndex].field === "taskName") {
          args.cancel = true;
          }
        }
</script>
[ASPX.CS]
protected void Page_Load(object sender, EventArgs e)
        {
            var DataSource = this.GetDataSource();                     
        }

Note:

A new version of Essential Studio for ASP.NET is available. Versions prior to the release of Essential Studio 2014, Volume 2 will now be referred to as a classic versions.The new ASP.NET suite is powered by Essential Studio for JavaScript providing client-side rendering of HTML 5-JavaScript controls, offering better performance, and better support for touch interactivity. The new version includes all the features of the old version, so migration is easy.

The Classic controls can be used in existing projects; however, if you are starting a new project, we recommend using the latest version of Essential Studio for ASP.NET.
