Process a GanttToolbarItem custom command

[Matthew]

How do you process a GanttToolbarItem custom command server-side?

The documentation https://docs.telerik.com/devtools/aspnet-ajax/controls/gantt/functionality/client-templates#toolbar-template here does not provide a C# example.

Hello Matthew,

The RadGantt does not have built-in support for triggering a postback from a custom command button. 

With that said, you can choose the best approach for your application to trigger the postback. Here are some common options: 

1) Programmatically click a visually hidden button and handle the OnClick server-side event;

2) Programmatically call the __doPostBack() method and check for the Request's __EVENTARGUMENT and __EVENTTARGET: https://www.codeproject.com/Articles/667531/doPostBack-function 

3) Trigger a partial postback using the RadAjaxManager:
