Hi Rad Team,

we are using a RadComboBox in an RadAjaxPanel and we have some issues in Firefox 3. In IE7 the page works perfectly, but in FF3 after the SelectedItem changed and the ajax call comes back there is problem, the ComboBox freezes and (other possibly RadControls in the same Panel).

Firebug reported me following problem:

uncaught exception: The container of an boundary-point of a range is being set to either a node of an invalid type or a node with an ancestor of an invalid type. (NS_ERROR_DOM_RANGE_INVALID_NODE_TYPE_ERR)

It also states this exception happens in line 8340 of the follwong code:

Hi,

In your demo http://demos.telerik.com/aspnet-ajax/fileexplorer/examples/default/defaultvb.aspx, when clicking "Enable paging for the grid " the paging slider and info (page 1 of ....) becomes visible.
When I set "AllowPaging=true" only the slider is visible and not the information block.

I also set

RadFileExplorer1.Grid.PagerStyle.PagerTextFormat = "Change page: {4} | Displaying page {0} of {1}, items {2} to {3} of {5}."

but it doesn't help.

Hi,

I have a fairly complex UI in my application and have decided to take the approach outlined in http://www.telerik.com/help/aspnet-ajax/ajxchangecursor.html

This approach works partially in that the hourglass does appear during the AJAX call;  however when the mouse is moved around during the AJAX call, the specified cursor is overridden whenever the mouse is positioned over asp:CheckBox or telerik:RadTextBox controls.

I was able to fix the situation for the checkboxes by dynamically changing/appending to the CSS class using http://stackoverflow.com/questions/195951/change-an-elements-css-class-with-javascript as inspiration but the RadTextBox controls ignore the new styles.

Is there a better approach to have the updated cursor apply to the body and all of it's child controls?

Thanks,

Dave

I've used the export to PDF from a simple grid and it works great.

My question pertains to using Export to PDF from a hierarchical grid with some additional complications.  I have a page (see attachment) which has not only a hierarchical grid but a summary section that sums data from the grid.  I'd like to throw all that info to a PDF.

Does the Grid based Export to PDF allow one to modify the contents of the output file by adding additional information such as I have here in my summary section?  I can't find any decent example in the help files.

If this is not a feasible solution, what would one do to build a PDF "report" in the middle of this page containing this grid plus summary information?

Thanks much,
JC

See the screenshot ; I have a simple "input type=text" control, an asp:Button, and below a RadGrid. You could see that the list of hints displayed by IE is shifted.
Do you have an idea about what could cause that?

Hi,

I'm using the scheduler to load list of read only appointments. So I set "AllowEdit="false" and also the "ReadOnly" properties of the respective monthview and dayview. It loads fine and displays the appointment.

But when I double click on any cell in the schedule (not on the area where the appointments are displayed but outside it), the page gets reloaded and all appointments are gone.

How do I prevent this?.

Thanks,
Prem

Hi,

I have a problem with IE8 and the RadWindow. I have uploaded a simple project at http://www.smallweb.nl/upload/danny/RadWindowTest.zip.

What I do is the following:
1. I have added a button, label, hyperlink and radwindow to the page
2. The hyperlink opens the RadWindow, using some javascript.
3. Using the add_close function of the RadWindow, a javascript function is called when the RadWindow is closed
4. When the RadWindow is closed, the command $get('Button1').click() method is called, which performs a postback to the server
5. The button is added to the RadAjaxManager as an AjaxControl. The Label is added as an AjaxUpdatedControl.

So when the RadWindow is closed, the button is clicked (using some javascript) and the label will be updated using AJAX. This all works fine in IE7 and FF, but not in IE8. 

Ien IE8, when the RadWindow is opened and closed for the second time on this page, there are two requests for this page at the server. When I set a breakpoint in the page_load event and check the IsPostBack property (which should be set to TRUE), in the 1st request this property is FALSE and also the click event of the button does not occur. In the 2nd request the IsPostBack property is TRUE and the click event occurs.
In IE7 and FF only one request to the server occurs (as it should be).

Is there a workaround for this problem?

Thanks,
Danny

In your samples you demonstrate that we nee to return IEnumerable of Appointment Data to the scheduler.

Is there something that runs in between of the scheduler and our web service?

I'm getting the following error when navigating to my web service on our staging environment

Cannot serialize interface System.Collections.Generic.IEnumerable`1[[Telerik.Web.UI.AppointmentData, Telerik.Web.UI, Version=2009.3.1208.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4]].

I've been reading in blogs that we shouldn't be returning IEnuermabl from a web service but rather something that can be serialized and therefore use the toArray method on IEnumerable and return that array.

I think this is the cause of another error I'm seeing when going straight to the page

The remote name could not be resolved: myschedulersite.test.com

thanks

Can anyone tell my why the grid columns would be in a different order on an Export than they are on the Web-Page?

Thank You,
Jim Harkins

Typing anything close to HTML into a RadTextBox seems to break it when it goes over the wire. I've tried escaping (encoding) it via javascript in the OnRequestStart, but that didn't seem to work... any ideas on the proper way to handle this (and without using a RadEditor).
