Filtered data not comming from all pages in the grid ?

I have a grid in which I have filtering as well as paging turned on.

When I am filtering the the grid based on a particular column, the rows which are matching in the current page are showing up in the filter result but the rows which are matching in the other pages of the grid are not comming in the filter result and I want them to come up in the result of the filter. Unable to do so.

Please help me out.

ExcelML export of templatecolumn

I understand why ExcelML export doesn't work on TemplateColumns out of the box, but it would be nice if you placed somewhere on the top of your ExcelML documentation something like "Limitation: this will not work with TemplateColumns". I would rather know there is a limitation than spending time trying to figure out why the control won't work the way I expected.

Furthermore, I have seen numerous posts about this issue (many of which would likely be unecessary with the little bit of additional documentaiton I mentioned above) and most of these point to a link which no longer exists ("Export Tips and tricks"), claiming there is some way to get the ExcelML export to work with template columns. So my question, since there doesn't seem to be any documentation, is do you have a work-around to be able to get template columns to export in an ExcelML scenario? If so, can you provide a VB example?

Printing RadWindow opened as a Modal window, is not using the print.css and is printing the parent page in Background

We are opening a pop-up window from the parent window with the following code. The child window which we are opening does not have any Telerik controls and it’s an external link. The window opens fine, without any issues.

In the new opened child page there is a Query which gets executed when the print button is clicked. When this Jquery is called it opens a print dialog box as expected, but when the window is printed, it’s not taking the print.css and also its printing the parent page.

.cs code
txtDDDD.NavigateUrl = "javascript:top.openMaximizePopup(‘URL’)

JavaScript Code in the parent page
function openMaximizePopup(url)

{

var oWnd = top.radopen(url, "modalPopup");

oWnd.SetSize(widthValue - 260, heightValue - 150);

oWnd.set_behaviors(Telerik.Web.UI.WindowBehaviors.Close + Telerik.Web.UI.WindowBehaviors.Maximize);

oWnd.set_modal(true);

if (title != "") oWnd.set_title(title);

oWnd.Center();

}

Javascript in Child Page

$(document).ready(function () {
