Text property getting space added after remote method call

I have a strange one here. I'm using a combobox which is dynamically created on the server and added to my form. I'm using loadondemand. I check the length of a text field for one of the items I added server side prior to the call to the remote method and the length of my text value is 7 characters. After I click on the dropdown and it goes out to retrieve more items and returns to my OnitemsRequested javascript routine, I check the length of the same item and it is now 8 characters. So essentially a space is being added to the end of the string. My remote method does not alter existing items in the combobox and only adds new items. Any known issues?

Ajaxify Timer For RadGrid DataItems

Hello Telerik and Everyone Else!

I've tried very hard to look for a similar question that has already been answered but unfortunately I couldn't find one. So please bear with me.

As you know there is demo about ajaxifying the timer here:
http://demos.telerik.com/aspnet-ajax/ajax/examples/common/ajaxifytimer/defaultvb.aspx

This demo updates the whole RadGrid every interval of the timer.

What if instead of updating the whole RadGrid every interval of the timer, each of the datagrid row gets updated at different times - say the 1st row get's updated every 5 seconds, the 2nd row at 10 seconds, the 3rd row at 8 seconds, the 4th row at 30 seconds, and so on and so forth.

I guess what I want is that each datagrid row will have its own separate dynamically created timer running at different intervals. How can RadAjaxManager handle that kind of a scenario? Below are some code snippets of my failed attempt:

    
            Public Class TCSTimer  
        
                Inherits System.Timers.Timer  
        
                Private mstrTag As Object 
        
                Private mstrName As String 
        
                Public Property Tag() As Object 
        
                    Get 
        
                        Return mstrTag  
        
                    End Get 
        
                    Set(ByVal value As Object)  
        
                        mstrTag = value

How to create a RadGrid column that accepts nullable dates (e.g. think an optional date) in MM/YY format?

Hello,
I have successfully created a grid and it's columns in the code behind and everything is working swimmingly, however now I need to support nullable dates in the pop-up grid editor. For example: Start date is required while end date is optional and often will not be populated. Currently if you edit the grid or want to insert a new record and do not specify a value for the end date, technically the pop-up editor thinks some kind of invalid datetime exception occured.

Now that i have provided the backup, I have two questions that I hope you can help to answer:

How can you create a grid column programatically that accepts null for date values (System.Date...does not work for this) when in edit/insert mode?
How can you use a built-in column editor for date values but have this values formatted as MM/YY when the column is defined programmatically ({0:d} works for 4/1/2010 but {0:MM/yy} in the dataformat for the column does not seem to work)?

Thank you!

Localizing ALL grids

You can localize all of the RadSchedulers in a project but just changing the RadScheduler.Main.resx file. Is there a similar option for the RadGrid? I have bunch of grids in a project.

Text rendered not updated when using client-side set_text();

I have the following javascript that is being called in the OnClientReordered event. I am trying to change the text of the items in the list when they are reordered. What I am seeing is the item does not update the first time the event fires. The second time the event fires the text gets rendered correctly. (The text is being changed properly, as I can put a watch on the values, and the text is correct. It is just not being rendered) Is there something I am doing incorrectly here? I could find no information from the documentation on the API.

    
            function SetcontentorderNumber() { 
        
                    reg = new RegExp("\\[\\d*\\]") 
        
                    var list = $find("<%= foo.ClientID %>"); 
        
                    var length = list.get_items().get_count(); 
        
                    list.trackChanges(); 
        
                    for (var i = 0; i < length; i++) { 
        
                        var text = list.getItem(i).get_text(); 
        
                        if (reg.test(text)) { 
        
                            texttext = text.replace(reg, "[" + (i + 1) + "] "); 
        
                            list.getItem(i).set_text(text); 
        
                        } 
        
                        else { 
        
                            text = "[" + (i + 1) + "] " + text; 
        
                            list.getItem(i).set_text(text); 
        
                        } 
        
                    } 
        
                    list.commitChanges(); 
        
                }

Hyperlink Option for Open in new tab

Currently the hyperlink configuration allows for "open in a new window". My business users would like another option to "open in a new tab". Would this be coming in a subsequent release?

Hide Event logic?

If you set HideEvent to "LeaveTargetAndToolTIp", and if you place your mouse over the target (let's say an image), the tooltip displays and after a few seconds it hides. If you set the HideEvent to "LeaveTootip", the tooltip doesn't hide in the same scenario. I am fine with using "LeaveTooltip" to create a persistant tooltip which doesn't hide unless the user moves their mouse off the target, however, it doesn't seem to match up with the avaialble HideEvent options. Shouldn't "LeaveTargetAndTooltip" be the one which persists the tooltip when the user is hovering over the target?
