Hello,

For now, it could not set via property. Please see my attachment sample for workaround. My idea is selectiong a row where it loads more.

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?

hi Madhavan,

My workaround can also work. Have you tested it? If you don;t want it, please try this new sample. Every time, you load more by scrolling down, it would mantain the scrolling position. Hope this would be more suitable with your scenario.

Handy

Hi Handy,

Thanks for the sample.

I will try and let you know.

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

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

	
	if(action=="More")
	{
		grid.AddInput("scrollTopPos", vl);
	
	}
	return true;
}
function ApplyLatestScroll(x) 
        {
            alert('in');
            var grid = ISGetObject("WebGrid1");
            
            grid.RootTable.GetElement(WG40.BODY, WG40.HTMLDIV).scrollTop = x;
            return true;
        }


 
 void WebGrid1_InitializePostBack(object sender, PostbackEventArgs e)
    {
        if (e.Action == "More" )
        {
            ISNet.WebUI.FunctionParameter[] parm = new ISNet.WebUI.FunctionParameter[1];
            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.

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

But my sample works fine, right? I think maybe different stuctures can have different result. It would be more helpful if you can send me a simple working sample and i will investigate for you.

Hi Handy,

Your sample is not working fine.

You are checking the following code in server side.

In my sample, could you record a video to show me when Request.Form["scrollTopPos"] is not getting from aspx page? I need to know to check in what behaviour that can cause the issue you told about.

Regards,
Handy

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,

Hello,

My previous scenario only supports to pesrsist the scrollbar not the selecting row. In fact, it is only working when scrolling, not click on LoadMore. Based on your scenario, i think the best approach is my first work around which is selecting a record after load more. Here is the modification i made on your modified sample. Hope this snippet codes could help you mantain your scenario.

function WebGrid1_OnAfterResponseProcess_1(controlId, actionName, lastRequestObject, xmlResponseObject)
{
     var grid = ISGetObject(controlId);
     window.setTimeout(function() { if (grid.TotalLoadedRows <= grid.TotalRows) grid.RootTable.GetRow(grid.TotalLoadedRows - 2).Select(); }, 1000);
     return true;
}

Handy
