RadComboBox on fous loses value in edit mode

[Imdad Turi]

Hello Every 1 and Telerik,

I have a RadComboBox, on edit mode the existing value gets cleared after losing focus. to clerify the problem i have applied TabIndexes on the form, this combo has TabIndex 1, after focusing via Tab Key whole value is selected and when i press Tab key again to jump to another control, the value get cleared. I have so many combos on the same form, those are working fine.
Any1 any idea please? Code for the Combo is below.

 <Telerik:RadComboBox IsEditable="True" Height="20" HorizontalAlignment="Left" Margin="90,3,0,0" x:Name="txtCatagory"
                                       Padding="0" VerticalAlignment="Top" Width="100"
                                     Text="{Binding SelectedCategoryName, Mode=TwoWay, NotifyOnValidationError=True,
                                      ValidatesOnDataErrors=True,
                                       ValidatesOnExceptions=True, UpdateSourceTrigger=PropertyChanged}"                                        
                                     validation:ValidationScope.ValidateBoundProperty="Text"
                                     OpenDropDownOnFocus="False"
                                     IsFilteringEnabled="True"
                                     ItemsSource="{Binding AllCategoryCollection, Mode=TwoWay}"
                                     SelectedValue="{Binding SelectedCategoryId, Mode=TwoWay}"
                                     SelectedValuePath="CategoryId" DisplayMemberPath="Code" TabIndex="1" IsTabStop="True" />

thanks in advance.

Hello Imdad,

I have tried to reproduce this issue with the latest version of RadControls ( Q3 2013 SP), but to no avail. Could you please confirm that you're using this release? If not, can you try to isolate the issue in a simple project and send it to us?  Note that you should open a support ticket and attach it there.

I am looking forward to your reply.

Hello Yana, i found out why this issue was happening, In telerik Combo there is a property "IsFilteringEnabled", if i keep this property true then that issue happens, if it is false then the combo works fine.
i need filtering, how to achieve the requirements and also avoid the above mentioned issue?

regards
Imdad

Hi Imdad,

Even with enabled filtering I did not manage to replicate the described behavior. Please try to isolate it in a simple project and send it to us.

Thanks in advance.
