Title: Grid Reference in Column Renderer
Post by: ralph1996 on October 25, 2016, 09:37:09 pm

How can I get a reference to the grid or the grid Element Id in the render callback for a column.  There is no event argument to use:

var $grid = $( event.target ).closest( '.pq-grid' );

Thank you

Reference to grid instance is available in any callback or event listener from context i.e., "this" variable.

var grid = this; //grid instance.

var $grid = grid.widget(); //grid DOM element wrapped in jQuery object.

Yes, that is what I expecetd but was nto seeing that. However,  I was calling a named function from the actual event handler and the named function scope is not the grid.  However if the handler passes its scope (this) to the named function I get the grid.

Thank You....
