Hello!

I have the 7.1 webgrid bound to a database and virtual LoadOnDemand. If i scroll down and try to delete a row by the delete-key, a unhandled exception is thrown in the javascript generated by the grid at this position:

function igtbl_deleteSelRows(gn)
{
	var gs=igtbl_getGridById(gn);
	var ar=gs.getActiveRow();
	
	if (ar && ar.IsAddNewRow) return;
	var del=false;
	if(igtbl_inEditMode(gn))
	{
		igtbl_hideEdit(gn);
		if(igtbl_inEditMode(gn))
			return;
	}
	if(gs.Node)
	{
		var arOffs=ar?ar.getIndex():0;
		gs.isDeletingSelected=true;
		var arr=igtbl_sortRowIdsByClctn(gs.SelectedRows);
		for(var i=0;i<arr.length;i++)
		{
			var row=gs.getRowByLevel(arr);
			if(row.deleteRow())
			{

The row - object at this point is null because there is no row at the position "arr.

This problem only occurs, if i want to delete a row with an index greater than the "UltraWebGrid.DisplayLayout.rowsRange".

Any suggestions?
