The RadGantt ColumnCreating is fired when a TreeList column is about to be created.

ColumnCreating event handler receives two parameters:

  • sender is the RadGantt control instance.

  • e is an object of type ColumnCreatingEventArgs. It gives you access to the TreeList column.


<telerik:RadGantt RenderMode="Lightweight" ID="RadGantt1" runat="server" OnColumnCreating="RadGantt1_ColumnCreating"></telerik:RadGantt>
protected void RadGantt1_ColumnCreating(object sender, Telerik.Web.UI.Gantt.ColumnCreatingEventArgs e)
    if (e.Column.HeaderText == "ID") {
        e.Column.AllowSorting = false;
Protected Sub RadGantt1_ColumnCreating(sender As Object, e As Gantt.ColumnCreatingEventArgs)
    For Each item As var In e.Tasks
        item.Title = "Modified Title"
End Sub
