Couldn't select the default item from RadComboBox

I am trying to add default item 'All' to my RadComboBox. It is adding at the end and also it doesn't select this default item. What could be the problem? Are there any other ways to do it?

function OnClientItemsRequested(sender, eventArgs) {  

      var combo = $find("<%= RadComboBox1.ClientID %>");  

      var intextput = "All";  

      var comboItem = new Telerik.Web.UI.RadComboBoxItem();  

      comboItem.set_text(intextput);  

      comboItem.set_value("");  

      combo.trackChanges();  

 

      combo.get_items().add(comboItem);  

      comboItem.select();  

      combo.commitChanges();  

      comboItem.scrollIntoView();  

    }  

 

 <telerik:RadComboBox runat="server" ID="RadComboBox1"   

      EnableLoadOnDemand="true"   

      OnClientItemsRequested="OnClientItemsRequested">  

      <WebServiceSettings Method="GetMyData" Path="http://localhost:1606/Service1.svc" />  

    </telerik:RadComboBox> 

 

I also tried with the following option. It adds the 'All' but it doesn't append the values from the database.





 <telerik:RadComboBox runat="server" ID="RadComboBox1"   

      EnableLoadOnDemand="true"   

      AppendDataBoundItems="true">  

      <WebServiceSettings Method="GetMyData" Path="http://localhost:1606/Service1.svc" /> 

       <Items>

             <telerik:RadComboBoxItem runat="server" Text="All" Value=""/>

       </Items> 

    </telerik:RadComboBox>

Recurrence Control Not Working

Hi,
I am using Recurrence Control,Having problem with Recurrence Rule.
Description :
Here I am trying to Schedule an Appointment having Start Date 08-02-2011 10:14 PM(dd/mm/yyyy) and End Date 09-02-2011 10:14 PM.
Please check Recurrence Details in attached file.
Following Recurrence rule is generated :

DTSTART:20110208T221400Z
DTEND:20000102T000000Z
RRULE:FREQ=MONTHLY;COUNT=3;INTERVAL=1;BYMONTHDAY=08

Which is not correct.It always takes DTEND as "20000102T000000Z". I think it should be "20110209T221400Z "

Also facing problem with visibility of Recurrence Control on Recurrence check box click sometime it works fine sometime not.

Can you help?

Please reply as soon as possible it's urgent.

Thanks,
Rahul.

Newly created folder get files from deleted folder with same name

Hi,

I'm having a caching issue where a removed file from a folder re-appears in a newly created folder with the same name as the old folder

Steps to reproduce:
1. Create folder with name A
2. Add a file file.txt to folder A
3. I right click on folder A and choose Delete. Folder A is deleted (folder and file deleted in backend)
4. Create a _new_ folder with name A
5. file.txt now appears in the grid in the newly created folder A.

In step 3, the file and folder is physically removed, and I have checked that I'm not mistakenly re-adding it in my custom ContentProvider.

6. Do a hard refresh (ctrl + F5), now file.txt disappears from A.

I'm using version 2010.3. I'm not using client side databinding.

Any suggestions on how to solve this would be much appreciated. I guess it has to do with caching? Is there a way to invalidate the cache for the deleted folder?

Best regards,
Andreas

Hi,

I trying to load data to a dropdown column from the code behind. I was using GridDropDownListColumnEditor which was working fine in telerick version of 2009 and the same is not working in 2010 version. Where as i am getting data which is binded in the grid instead of getting
binded from the datatable. The below i have given my code

ASPX :

SortExpression="user_type" UniqueName="user_type" ListTextField="user_type_name" ListDataMember ="user_profile"
ListValueField="user_type" >
