Index out of range exception

[Doug]

I'm getting this exception, it is kind of hard to reproduce but ill try to explain.

I could'nt reproduce this on an emulator, so i suggesst using a phone. type in some string in the autocomplete box and delete it fast, it doesn't always crash so u may repeat this a few times.

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

   at System.Text.StringBuilder.Remove(Int32 startIndex, Int32 length)
   at Telerik.Windows.Controls.AutoCompleteProvider.Delete(Int32 start, Int32 selectionLength)
   at Telerik.Windows.Controls.RadAutoCompleteBox.RefreshSuggestionOnTextDelete()
   at Telerik.Windows.Controls.RadAutoCompleteBox.OnKeyDown(KeyEventArgs e)
   at System.Windows.Controls.Control.OnKeyDown(Control ctrl, EventArgs e)
   at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)

Hello Doug,

Thanks for writing and for reporting this.

I would like to inform you that we have addressed a very similar issue with AutoCompleteBox recently. We haven't had the chance to release an Internal Build containing the fix yet but we will be able to do this next week.

Just to make sure the scenario is the same: do you have the FilterDelay property set to a value different than TimeSpan.Zero in your project?

Hi Deyan

I didn't set neither of those properties, so i guess they have their default values.
I hope we are talking about the same issue. Ill check out the internal build next week for fix.

Hello Doug,

Please, check out the Internal Build and let me know if the issue persists.

Can you please tell me if the issue is reproducible in our Demos Application so that we continue investigating using the demos there?

Hi

I checked the internal build, and the problem still exists.

I also tried with the examples and i could reproduce. 

Steps to reproduce:

1) Open Autocomplete 
2) select web service example
3) write in "don"
4) don't wait for loading, delete all with delete button on keyboard (fast)
5) write in "john"
6) dont wait for loading, delete all with delete button keyboard (fast)
7)Repeat steps 3-6 untill error occurs

Unfortunately i dont know which version of example im using but i think it doesn't even matter.

Best Regards Doug

Is there an update to this? I am seeing bug reports with the exact same stack trace in version 2013.3.1016.3040

Are there any workarounds if a fix has not been published?

Hello Tim,

This issue should be addressed. To make sure that this is not something else, we would like to learn some more details about the scenario. We will try to reproduce the glitch on our side and see how to fix it.



Thanks for your time.
