Grid autoheight enhancement

[guest]

When dealing with a grid where you have the possibility of content below the grid - it would be nice to have an option to use autoheight until some threshold for number of rows is passed, then move to a fixed height solution. Currently I have a generic grid where the number of rows in the grid could be anywhere from 1 to 500. autoheight in that solution is not acceptable when the grid has 100's of rows. Fixed height looks horrible when there are very few rows and a large area of blank space hiding the other content under the grid. I would like to have a way to tell the grid to switch off autoheight mode after x number of rows. I tried hacking a solution using something like this:

var grid_onComplete = '';

function grid_size_check (items, request) {
	console.log('onComplete - len: ' + items.length);

	if (items.length > 10) {
		// more than 10 rows, switch to fixed height
		theGrid.autoHeight = false;
		theGrid.domNode.style.height = '300px';
		console.log('fixed height');
	}
	else {
		theGrid.autoHeight = true;
		theGrid.domNode.style.height = '';
		console.log('autoHeight');
	}

	console.log('updating size');
	theGrid.update();
	theGrid.resize();

	// call the real onComplete callback.
	grid_onComplete(items, request);
}

dojo.provide("custom.GridItemFileReadStore");
dojo.declare("custom.GridItemFileReadStore", dojo.data.ItemFileReadStore, {
	fetch: function(request) {
		console.log('custom fetching - height: ' + theGrid.domNode.style.height);
		console.log (request.onComplete);
		grid_onComplete = request.onComplete; // save off the store's current onComplete 
		request.onComplete = grid_size_check; // this hoses things up 
		
		// Call superclasses' fetch
		return this.inherited("fetch", arguments);
	}
});

This somehow stopped working for me though. Ideally would be nice to say autoHeightRows="20" which would instruct the grid to automatically set height until 20 rows are reached, if more than that show scrollbars.

Thanks!

oops - forgot to enclose JS in wiki tags - can someone please modify?
