JavaScript Error after close RadWindow and Postback

I have a RadWindow to show comments when I click button of GridButtonColumn of a RadGrid. When I click, in the ItemCommand event of the RadGrid I have the following code:

protected void rgQualityReport_OnItemCommand(object sender, GridCommandEventArgs e)

{

if (e.CommandName == "ShowComment")

{

GridDataItem dataItem = e.Item as GridDataItem;

comments.Content = dataItem["ColumnDate"].Text;

this.modalPopupComments.VisibleOnPageLoad = true;

RadWindowManager1.DestroyOnClose = true;

RadWindowManager1.Controls.Add(modalPopupComments);

}

The problem is the following:When I click the button, the radwindow is showed correctly. However, after close the radwindow and reload the page, in a postback reload I have the following error:sys.webforms.pagerequestmanagerservererrorexception JSCRIPT error.

Can you help me, please?Thanks!

RadGrid responsive

Hi!
Is there any way in Telerik to have a responsive grid? I use it in a web page and with a lot of column headers, I wish it was as responsive as the grid in the link below for every device in any resolution:
http://fooplugins.com/footable-demos/
Alternatively, is there any way to integrate footable attributes in a telerik radgrid?

Thanks!

Styles from TableLayoutCSSFile loading in "Select CSS Class" dropdown

We have had our RadEditor working with a custom editor CSS file for a while, and the "Select CSS Class" dropdown properly shows just the classes in that file. I've been asked to add a TableLayoutCSSFile to provide a custom table format. Once I add the table file to the config, the table styles begin showing in the class dropdown.

Is there any way to prevent this? We don't want users to have to scroll through tons of table styles, just to get to the content styles at the bottom of the list.

Flickering of RAD Date Picker and Drop Down lists

Hi,

We were using ASP.net AJAX Q2 2013 along with VS 2010 for our development. Recently we upgraded the environment to VS 2013 and Telerik ASP.net AJAX Q3 2013 RAD Controls. Now we find that in all the web pages where we have the RAD Date picker, the control flickers in IE11 on post back. Also for drop down lists, the user has to click twice to get it working. There is a considerable slowness in these controls. This is happening only in IE11 and works fine in chrome. This was working correctly in IE 11 when we were using Q2 2013. We cannot tell our clients to use chrome since our application works best in IE.

We are now hesitating to provide our latest build to our clients due to the slowness of these controls. What could be the possible issue and are there any workarounds or fixes for this? An early action from your end is appreciated.

Thanks and Regards

Slider with tooltip

I implemented a page similar to the demo here:
http://demos.telerik.com/aspnet-ajax/slider/examples/rangeslider/defaultcs.aspx

My page has a single slider and a tooltip that follows the drag handle. The tooltip shows text information and is visible at all times. This page works great.

Now I want to add a second slider on the page with a similar tooltip. However I have found out that only one tooltip can be visible on the page at the same time. So what I thought was going to be an easy change is now not so simple.

Is there any way to show two tooltips at the same time? If not, do you have an example or suggestion on what control I should use in place of the tooltip to implement similar functionality?
