Hi,

I have a page with some controls and the last control which is below all other controls is a TreeList.
This TreeList can contain more data than it could fit on the screen, so it automatically gets bigger than the browser window and the
browser displays scroll bars. This could be ok, but the LoadingPanel image could be outside the viewport if there are too many rows.

So I want to prevent that the TreeList grows bigger than the page. I know I can set AllowScrolling to true, but this seems to work only for fixed heights, not relative ones.
Could you please tell me how I can prevent the TreeList from growing larger than the viewport?

Thanks!

Hi

I am testing a new website with IE8 and Chrome 2.0 and noticed some strange behavior with Telerik TreeView. I'm using Telerik.Web.UI Version 2009.2.701.35. On this Website, I have 2 TreeViews which works great in FireFox without any problems, but if I open the Website in Internet Explorer 8.0 or Chrome 2.0 the left TreeView doesn't work. Screenshots:

Website in IE 8.0: http://bit.ly/cqvc6

Website in Chrome 2.0: http://bit.ly/6YkBU

Both Browsers are installed on Windows Vista SP2 with default Settings (I made no changes to the configuration after installation)

 

In IE 8.0 I receive many of the following JavaScript Errors:

Do you have any suggestions to fix this problem.

Thank you in advanced.

I have a question about the groups. I see from the examples in the help about how the groups can be used with the core scripts that most controls use. What about other telerik controls?

I have one particular type of page that has a telerik grid, buttons, textboxes, combo boxes and a window on it. I use this same display page in numerous spots in my web application (but not on every page). Could I combine the scripts for these controls into a group so the script manager will cache these scripts in this combination and then know to get the cache for this page?
 
If so then how would I do that? So in other words when it encounters this page it gets the cached scripts for the control combination but if it encounters another page that say only has a radgrid and buttons on it then it would use the normal script combine method.

When I click the edit button, I will get javascript error for "value of 1/1/0001 12:00:00AM is not valid for selecteddate. should between mInDate and MasDate, parameter name "SelectedDate".
My date field "ProcessedDate" is a read only field, not sure why I got this error and how to solve it?

Thanks

I am having a RadTreeList control in my page. I need to validate that every first hierarchy items(0th Nested Level items) can have only 5 levels of children( not 5 children) i.e., each 0th Nested Level items can have 5 hierarchical levels. I am using both item creation method and drag-drop method. While dragging from some item to an item, I need to validate that the destination item has only 5 hierarchical levels after dropping. If the sum of hierarchical levels is equal or greater than 5, then the dragged item should not be allowed to drop to the destination item.
Can anyone help for this.

Thanks in Advance,

Hi,

I am using Rad Scheduler to show the appointment on daily basis. What i want is, that if there is no appointment for a particular slot then that slot should not be created.
for example i have this on datatable  
9:00 Am to 10:00 Am | Do something
10:00 Am to 11:00 Am | Do nothing
and then
1:00 Pm to 2:00 Pm | Do something Again

so what i did, i have set 9:00 Am as start time and 2:00 Pm as end time
it had also created time slot for 11:00 to 12:00 and 12:00 to 1:00 which are not in Datatable.

i did tried 
 if (e.TimeSlot.Appointments.Count < 1)
        {
            e.TimeSlot.Control.Visible = false;
          }
but still i can see hours on Hours Column and blank space in between the time slot.
is there any way i can stop the time slot from creating or create timeslot according to slot's in Datatable.
Please help.
Thanks

I have the following setup as shown in the markup below. There is an ajaxified panel which contains an imagebutton and a hyperlink. Clicking on either of these opens a rad Window, which has a close handler. The close handler initiates the "click" event of a hidden button in order for me to be able to run some server-side code after the window closes. When I open the radwindow using the hyperlink, everything works as expected. When I do so using the image button, I get the following non-descript javascript error when the hidden button .click event is raised.

Error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 405

This error doesn not occur if I don't ajaxify the panel.

I have tried to research this error and track down the cause, but to no avail. When I look at this in Fiddler, I notice the URL that fiddler errors on is .{my path}/javascript:void(0);. I don't know where the javascript:void(0); comes from... but I obviously include that in the Imagebutton PostbackUrl to prevent a postback when the imagebutton is clicked. I also don't know why this piece of the imagebutton declaration would have anything to do with this since the error occurs on the attempt to raise the hidden button's click event.

Any Idea why the image button implementation wouldn't work, while the hyperlink does?

Markup:



In code-behind, I ajaxify the panel using an ajaxmanager which is part of my page base class:

We use the RAD Tab strip to divide the form under various sections and noticed that when we try to set a textbox value of one tab with value entered in another tab, we get an overlapping style in the target textbox.

This happens if the target textbox has a empty message set. I've attached the markup code below:
