Hi Telerik Team,

I've use telerik for couple of weeks. My radcombobox's data is huge it's like 2000-3000 rows so when I use the arrow up and down for change the selecting item is too slow.

So I need the paging feature like gridview. Is there any way to modify Load On Demand feature to support the shown data on the number that I want.

The example is I want to show first 100 rows after user click More Result Box to load next 100 rows I need to show only next 100 rows not include first 100 rows. I need this feature because when data is bound on less number of items can be use the arrow up and down in faster than huge rows.

Thanks in advance,
-Toi

Problem with grid horizontal scrollbar

Here's my code to create dynamic grid. My grid width is 500px and I have 6 columns of 100px each. My problem is that my grid can't display horizontal scrollbar. Do you know why ?

Me

Setting default text via Javascript

Hi,
I'm looking to add some text/html to a rad editor on page load.

The Rad Editor is being used on a NewForm.aspx page as a replacement for the default rich text editor. As the control is being added dynamically, i can't obtain a reference using the control name:

    
            var editor = $find("<%=RadEditor1.ClientID%>");

So my approach is to traverse over the DOM and find the ID of the RAD editor control. I can do this successfully using the below javascript:

    
            <script type="text/javascript">  
        
            _spBodyOnLoadFunctionNames.push("fillDefaultValues");  
        
            function fillDefaultValues() {  
        
             var oJobBrief = getTagFromIdentifierAndTitle("textarea", "TextField", "Job Brief");  
        
             var temp1 = oJobBrief.parentNode.previousSibling;   
        
             var oRadEditor = $find(temp1.id);  
        
             oRadEditor._contentArea.innerHTML = "test";  
        
            }  
        
                function getTagFromIdentifierAndTitle(tagName, identifier, title) {  
        
                  var len = identifier.length;  
        
                  var tags = document.getElementsByTagName(tagName);  
        
                  for (var i=0; i < tags.length; i++) {  
        
                    var tempString = tags[i].id;  
        
                    if (tags[i].title == title && (identifier == "" || tempString.indexOf(identifier) == tempString.length - len)) {  
        
                      return tags[i];  
        
                    }  
        
                  }  
        
                  return null;  
        
                }  
        
            </script>

Using the $find function on Firefox returns a reference to the Rad editor instance. However I get nothing back when doing this from IE.

Can you help? Is there an easier way to set text in the rad editor for a specific page?

Does ImageManager provides advanced security like group level access?
I couldnt find a way to handle this there fore I am planning to customize the image manager so that the images will be saved in a different way with security

How to make a resource and all connected timeslots invisible

Dear Staff,

i would like to do the following task.

I have severall rooms (defined at Design Time) and i want to show/hide this rooms depending on the current users rights. These rights are stored i a seperate database table (None/View/Edit).

i found that it is posible to hide a resource header and to disable a timeslot depening on resource text, but when i hide the header the needed space in radscheduler is still occupied.

Any suggestion how to simply hide a resource ?

another possible way would be to create the resource at design time.

Kind Regards

Martin

Auto Scroll During Drag & Drop

The horizontal scrolling that you all have added with Q3 is great, works very nicely. I wanted to see if it would be possible to add a new feature to enable auto-scrolling of the scheduler during a drag & drop operation? However, now when I use that in conjunction with the vertical scrolling in a timeline view, if my resource or timeslot that I want to drop onto is not scrolled into view, I need to manually scroll the scheduler in order to be able to drag & drop. In some cases this is not possible; e.g when I have a long listing of resources (and want to drag from the first to the last resource) or a large width set on my slots (or a large number of timeslots, like 24) and want to drag from the first to the last timeslot.

We are also performing drag & drop from a RadGrid onto the RadScheduler and if there were some way to enable auto-scrolling of the RadScheduler during this operation that would be fantastic.

Thanks.

Paige
