I’ve got a toolbar above a grid. The toolbar contains a text input item that I want to use as a Filter input for all grid columns. I need to trap a timed-text-input event, like the grid header filters do.
You may use the following approach to get input object (itemId is the id if the input button):
var inputObj = toolbar.objPull[toolbar.idPrefix+itemId].obj.firstChild
And create a filter:
grid.makeFilter(inputObj,columnIndex);
Here is the article in the documentation:
