FYI: this is basically an edit of a previous post.  Original didn't allow edits.

Please add a Server Side event for OnBlur or OnClose for the RadComboBox with the option for an auto postback.

The Telerik support team suggested using the "TextChanged" event.

However, this does not work for my purpose and here is why:

Mainly because it appears that an event fires immediately after each check/uncheck.

I have been using a dropdowncheckbox control by another vendor in multiple projects over the past 3 years (many, many instances).  It fires an event when you click anywhere out side the dropdown or when you collapse the dropdown (close).  This is perfect because many of these dropdowns supply parameters to SSRS reports that are generated on the webpage and I can iterate through the object and process all of the items that are checked at the same time, pass all parameters to the various reports.

Users of these website have requested that after selecting (checking) which values they want to choose, they want the reports to run automatically and don't want to click a "Run reports" button. I am doing this currently with the other control.

*** How could I possibly determine when the user is done checking/unchecking items using the "TextChanged" event?  

With an OnBlur or OnClose event it's a No-Brainer.  Event --> Do Processing...

Our company made a decision to standardize our tool set and picked Telerik as that toolset vendor.  The lack of having an event that fires similar to the control that I have been using in the past will require unnecessary code modification.

In summary, if there was a similar event I could simply rename each instance of my C# event handlers (methods) across all projects, then modify that code to iterate through the RadComboBox instead of the control I currently use and be done.  Find --> Replace, mostly. 

For the one (1) instance of the RadComboBox that I have tried I was able to create a work-around by placing code in the IsPostback of the Page_Load event and iterate through the radcombobox, getting the checked values and then doing whatever processing  needs to be done.  This not work for most of the pages in my projects mentioned above due to different circumstances.

Thanks!

The input box (TextBox) portion of the Rad Combo box could benefit from the ability to customize/format the data presented within said element.  Having the ability to toggle it to a multi-line TextBox would aid in this ability as well.  Having the ability to implement custom html in the form of a template, perhaps a SelectionBoxTemplate, would open the control of the display to be completely customizable.

Please consider this enhancement in a future release.

Thanks...

the dorpdown area doesn't support html encoded data.

In Lightweight rendering mode, the drop-down arrow has cursor type 'text' instead of 'default' in Internet Explorer (11).

We have evaluated your controls for few days for the last 4 years now. And you still dont support check boxes and load on demand. (we keep getting the same response from your forms). There are other companies already do that. If you can include this feature in your future development that will be great. 

We can not use RadAutoCompleteBox control as the users do not what they are searching for. 

How come no one else asking for this. All what needed is to cache the values after the control is loaded. 

Thanks.

The bug occurs when checkboxes are enabled and one or more items are set invisible on the server-side (Visible=false). Checked items are not persisted correctly between postbacks. I have included a sample project to show the incorrect behavior.

Steps to reproduce to problem:

1- Start the sample project
2- The first combobox has 10 items. The first one has been set invisible.
3- Check an item
4- Click the "Select" button
5- The wrong item is checked. The checked item change at every postback

Also, the RadComboBox control should automatically select the first visible item instead of the first item of the list. The second combobox of the sample projet shows this behavior.

Thank you for looking at this issue.

add ability for radcomboboxitem to expose the attributes collection for the selected item when client-side binding occurs via a webservice.  (based on support id 87724).  Currently only selected text and values are accessible when posted back.  The attributes related to the selected item are as important to provide proper context once on the server side.  Again, this only necessary for the selected item, not all items as I understand the ramifications to client side performance.
