Hi Handy,

I have copied your sample page contents to my test project.

Please find the attached sample. 

To be more clear Say if we are having 100 records and virtualpagesize is 20.

First we are in Page1 where we are seeing 20 records.

When we do a scrolling or click on LoadMore Icon the Scrollbar should point it around  38th  record position or so.

Thanks in advance,

Hi Handy,

In The sample there is no scrollposition getting passed from client side.

I modified the sample based on webgrid 4.0 sample.'

But always

grid.RootTable.GetElement(WG40.BODY, WG40.HTMLDIV).scrollTop is returning 0.

Please advice.

Madha

{	
	
	debugger;
	var grid = ISGetObject(gridId);
	
	
	var vl = grid.RootTable.GetElement(WG40.BODY, WG40.HTMLDIV).scrollTop + "";

	
	if(action=="More")
	{
		grid.AddInput("scrollTopPos", vl);
	
	}
	return true;
}

        {
            alert('in');

            grid.RootTable.GetElement(WG40.BODY, WG40.HTMLDIV).scrollTop = x;
            return true;
        }

            parm[0].Type = "x";

            
            parm[0].Value = Request.Form["scrollTopPos"];
            if (parm[0].Value != null)
            {
                
                WebGrid1.ClientAction.InvokeScript("ApplyLatestScroll", parm);
            }
        }
    }

grid.RootTable.GetElement(WG40.BODY, WG40.HTMLDIV).scrollTop is returning 0.

Please advice.

Hi Handy,

Why we were not able to maintain the Scroll position?

It is always going top after scrolling down.

So many of our customers are asking for this.

Can you please check with your developers and let us know?
