Filter case sensitive?

[Sergey]

We've noticed that at some point recently all the ComboBoxes that use the Filter property have become case-sensitive. This is true for both StartsWith and Contains settings, and seems to be the opposite of what the documentation suggests (which states that Filter is case-insensitive). 

We've fairly recently upgraded to the Q2 Telerik release from Q1, and I think it may have been after this upgrade. 

I'm just wondering if this is a new default behaviour, and if so how do you override it to the previous case insensitive version, or if this is a bug? 

Our Telerik DLL version is 2010.2.713.40, using .NET 4. 

This is a slightly stripped down markup of one of the ComboBoxes which has this problem. 

<telerik:RadComboBox ID="Combo" runat="server" AutoPostBack="true" Skin="Windows7" AllowCustomText="true" DataSourceID="OurDS" EnableAutomaticLoadOnDemand="true" EnableVirtualScrolling="true" EnableLoadOnDemand="true" ItemsPerRequest="30" EnableItemCaching="true" Filter="Contains" ShowMoreResultsBox="true" DataTextField="TextField" DataValueField="ValueID"                         EmptyMessage="Search..." OnSelectedIndexChanged="Method_SelectedIndexChanged" Width="175px" />

Hello Sergey,

I just verified all cases of automatic Load On Demand in our demos with the latest version of Telerik.Web.UI and they worked properly. Moreover I consulted with our developers and they let me know that in our code we are using case insensitive culture invariant comparisons (when we filter the data in-memory).

Could you open a support ticket and send us a project showing this issue so that we inspect it?

Best wishes,
