I have a databound event that is used on grid but also on a treelist (at first it was grid). Is there a way to determine the type of the e.sender?

Hello, Dan,

As both the TreeList and the Grid have their own dataBound event, the e.sender will always be the widget that is triggering the event. Could you please let me know if I am missing something from the question?

Hi Martin,

You are missing exactly the question. Determine the type of the sender (if it is a Tree or a Grid)

Example

function dataBound(e) {
   console.log(typeof e.sender); // this is object
    if (e.sender ?? TreeList) {
        console.log("The event was triggered for a TreeList");
    } else if (e.sender ?? Grid) {
        console.log("The event was triggered for a Grid");
    }
}
I am using the same event cause the functionality should be the same but it seems that the 2 controls do not behave in the same way so for a TreeList I have to do some more work in order to have the same functionality as for a grid.

You can whether the e.sender.options.name is "TreeList" or "Grid". Here is a small example for reference.
