I have a radgrid in a user control and am using the following code to capture and retain the scroll bar position after a postback

 

<ClientSettings EnablePostBackOnRowClick="True" EnableRowHoverStyle="True">

 

 

<Scrolling AllowScroll="True" UseStaticHeaders="True" SaveScrollPosition="True" ScrollHeight="295px" />

 

 

<ClientEvents OnScroll="SetScrollPosition" />

 

 

<Resizing AllowColumnResize="True" />

 

 

</ClientSettings>

 

<

 

script type="text/javascript">

 

 

 

 

function

 

SetScrollPosition() {

 

 

var y = DBSearch1_RadGrid1_GridData.scrollTop;

 

document.cookie =

"divPos=!^^->" + y + "<-^^!";

 

}

window.onload =

function() {

 

 

var cook = document.cookie;

 

 

if (cook.indexOf("!^^->") != 0) {

 

 

var start = cook.indexOf("!^^->");

 

 

var end = cook.indexOf("<-^^!");

 

 

var pos = cook.substring(start + 5, end);

 

window.setTimeout(

function() {

 

DBSearch1_RadGrid1_GridData.scrollTop.scrollTop = pos;

}, 0);

}

 

}

 

</

 

script>

The problem I am encountering is that the scroll bar does get set to the value of 'pos'  but within a split second it gets reset and is at the first record in the datagrid after a postback. I was wondering if any one has encountered similar issues. Thx

I am experiencing this problem as well with the latest (2011.3) version. I was hoping that you had a solution because I can't find one yet.

Hi Princy,

Thanks, but I have been there and done that. The settings there are not working in my situation and I still have the problem. I have a trouble ticket open, but was hoping that maybe someone else has ran into this problem and found a solution that I haven't tried yet.

Thanks,
Rich

Hi Tony,

Actually the problem that Richard faced was determined as bug.The problem appears only in IE9 browser and no matter if ajax is used on the page.
After further researching on our site we concluded that the problem is in the filtering item of the DateTime column. For some reason it receives a focus after postback and this causes the issue.
The presented problem is a bug and we have logged it into our tracking system. Our dev team will further investigate the issue and will do the best to provide a fix as soon as possible.
As for workaround, for now you could hide the picker from the filtering item by settings PickerType="None" for the DateTimeColumn
