RadComboBox not reloading when selection is cleared

[ranro]

We are having a couple of issues with the RadComboBox not reloading when the selection has been cleared.  These issues only appear in Internet Explorer and can be reproduced on Telerik's website at http://demos.telerik.com/aspnet-ajax/combobox/examples/default/defaultcs.aspx

Issue #1:
1. Click into the Region RadComboBox.
2. Type or paste a valid value into the Region ComboBox ("Cambridge" is a good example)
3. Click or Tab out of the RadComboBox and it will reload with only the item that was typed into it.
4.  Click back into the Region RadComboBox.
5. Clear the Highlighted text with delete or backspace; notice the list does not request new items and reload.

Issue #2:
Click or Tab out of the field again; notice that the text area is populated with the old value.

Issue #2 is probably a direct result of the item list keeping the previous selection in Issue#1.  We need the RadComboBox to reload the original list when the selection is cleared out of it.

Hello,

I'm experiencing this issue, too. Has there been any progress on the fix, or is there a workaround of some kind that can be used to correct the issue until another release becomes available?

Hi Brian,

I tested the issue described at the first post in this thread under Internet Explorer using the online demo mentioned. The RadComboBox behaves as expected and the issue does not appear.
Which version of Telerik.Web.UI are you using in this application?
Let me suggest you try downloading our latest Telerik.Web.UI version and test the RadComboBox behaviour on your side.
If the issue persists – could you please provide us a sample code that replicates it and explain in more details how to reproduce it?

Greetings,

Actually I am able to reproduce this on the Telerik demo site using IE 8, just as the first post from May 21 describes. Using the demo page you included - http://demos.telerik.com/aspnet-ajax/combobox/examples/default/defaultcs.aspx:

1. Click on the Product dropdown
2. Type "Gei", then choose "Geitost" from the filtered results
3. Tab away from the Product dropdown, or set focus to another control
4. Click on the Product dropdown again, but specifically click the arrow icon - not the textbox area of the dropdown
5. When the dropdown displays, the cursor should show to the left of the text in the dropdown. Highlight the text and press Backspace or Delete. No event seems to fire, and the results displayed in the dropdown do not get reset. They remain filtered to the dropdown item that matches the text.

I'm able to consitently reproduce this behavior. It seems to happen less often when you click the text box to open the dropdown but more when you click the down arrow, for some reason. Once it does start happening, I'm not able to get the dropdown to reset unless I either highlight the text in the textbox type a space, or move the cursor to the end of the text and press Backspace to delete one character at a time.

I agree with Brian.  We still consistently get this error using Internet Explorer.

Hi,

Thank you for the clarification.
I tried to reproduce the issue again but unfortunately without success.
Could you please take a look at this demonstration video?
Maybe I miss something?

Your video does point out a difference in the way we're clearing the contents of the textbox. I see that you're highlighting the text with the mouse pointer, and that seems to be the key difference. When I highlight the text, I'm using Shift + End or Shift + rightarrow and it when I clear the text that way it doesn't reset the dropdown. So maybe the issue is with a particular set of keystrokes?

Hello Brian,

Thank you for the clarification.
We are aware of this issue but I am afraid that there is no solution available at the moment.
We will contact you if we find something of interest.

Hi!

Has this been fixed yet?
I am having a similar problem where I am clearing the combobox and then setting focus using javascript.
The control recives the focus but does not load the items.
If I click on the arrow nothing happens, but after I use the mouse to set focus to the control, everything works okey again.

Hi Per,

Could you please explain your implementation in more details and provide us working code that reproduces the issue?
Thank you in advance.

Has this ever been fixed? I currently have this problem.

To shed some light- my RadComboBox is set up as follows: 

<telerik:RadComboBox runat="server" ID="cbo" EnableLoadOnDemand="True"
                Font-Names="Tahoma" Font-Size="11px" Width="100%" DataTextField="Name" DataValueField="Id"
                OnItemsRequested="cbo_ItemsRequested" AutoPostBack="true" Filter="Contains"
                HighlightTemplatedItems="true" Height="140px" DropDownWidth="400px" OnSelectedIndexChanged="cbo_SelectedIndexChanged" >
            </telerik:RadComboBox>

Hello Andrew,

Could you please explain in more details what exactly the issue that you encounter is?
Please provide us a working sample that illustrates your implementation.
In order to help you we need to reproduce the issue locally and investigate what causes it.

Hello,

Are you experiencing the problem Randy Rollins has described, with the RadComboBox not properly loading its items when the text in the input area is cleared?

Which version of our controls you are experiencing the issue with?
