Cannot scroll scrollbar to bottom of grid

Posting again under the right group.
I am using below code to handle a paging grid and it is being called in the onScroll event. It works for most grids, however I have one where

this.objBox.scrollTop = this.LastScrollY;

results in scrollTop not being set to LastScrollY, it is being changed to something else behind my back, which generally is a lower value, so the view is being janked right back up, i.e. I can never seem to get down to the bottom.

[code]dhtmlXGridObject.prototype.ResetInternalView = function(oPanel, bForce)
{
if (bForce)
{
oPanel.progressOn();

    this.startFastOperations();
    this._reset_view();
    this.stopFastOperations();

    this.LastResetViewY   = this.LastScrollY;
    this.objBox.scrollTop = this.LastScrollY;

    oPanel.progressOff();

    return;
}

if (this.LastScrollY > this.LastResetViewY)
{
    fNumRowsScrolled = (this.LastScrollY - this.LastResetViewY) / 20;
}
else
{
    fNumRowsScrolled = (this.LastResetViewY - this.LastScrollY) / 20;
}
          
if (fNumRowsScrolled >= 50)
{
    oPanel.progressOn();

    this.startFastOperations();
    this._reset_view();
    this.stopFastOperations();

    this.LastResetViewY   = this.LastScrollY;
    this.objBox.scrollTop = this.LastScrollY;

    oPanel.progressOff();
}

};
[/code]

I am uploading a screenshot of how it looks like when running in the debugger, it is really surreal to see the value suddenly change to something else behind my back.

Looks like the onScroll event is being triggered again by setting the

this.objBox.scrollTop value

I tried setting the value to index*20 instead and it went into a never-ending loop, constantly changing the scroll bar position. Is there a way to turn off the event, so that I can reset the view and set the scrollbar to the original position?

The issue turns out to be the fact that the grid having issues have Multiline enabled ontop of SmartRendering/Paging.

How would one go about calculating the number of rows you have scrolled, if the rows are not the same height?

i.e. how do you set the scrollbar back to where it should go after a reset when Multiline is enabled?
