ComboBox search incorrectly

[Sompop]

Hi there,

All the sudden, the RadComboBox acts very strange in IE browser even if I do not change any code and it just started a week ago. I am not sure if this is due to Microsoft update or what else could cause it.

Here is the code.

Case: 1
                        <telerik:RadComboBox ID="rcbCompany" runat="server" DataSourceID="SQLDS_CompanyList"
                            Skin="Gray" AutoPostBack="True" Height="200px" Width="390px" MarkFirstMatch="True" 
                            DataValueField="companyGuid" DataTextField="company" OnSelectedIndexChanged="rcbCompany_SelectedIndexChanged" />

Say one of the company is "My Company".

When I typed "My" it does not show the company. However, if I type "ym", it will show. It will not happen to FireFox and Chrome.

Case: 2

                                <telerik:RadComboBox ID="rcbModel" runat="server" DataSourceID="SQLDS_Model" Skin="Gray"
                                    AutoPostBack="False" Height="200px" Width="200px" MarkFirstMatch="True" DataValueField="model"
                                    DataTextField="model" AllowCustomText="true" ToolTip="Enter or select model" />

Say one of the model is "PT-9500".

When I typed "pt-", the first letter that I type will be the end of the word that I typed. In this case, it will change from "pt-" to "t-p" and it will not find what I would like to.

I have not updated the code for at least two weeks and it just happened for IE only. Please let me know how do I solve this problem.

Thank you,

Hello Vincent,

I am not sure about the version you are using. IE 9, FireFox 4 and Google Chrome10 are supported by controls starting Q1 2011. If you are using IE9 I suggest you to migrate at least to version 2011.1.315. With older versions these browsers are only partially supported.
Updating RadControls for ASP.NET AJAX to another version or license.

Thanks,
Shinu.

Hi Shinu,

It has been working fine for IE8 and all the sudden it started to happen. With IE9, the problem for IE seems to be resolved when I use Document Mode: Quirks. Again, I have not updated the source code or deployed in the past two weeks, but the problem just started this week. I am wondering if you think it is possible that Microsoft update something for Browser and it only effects on the telerik version that I am using only.

If you have any idea to work around this, please let me know before I can get an approval to get a newer version.

Thank you,

Sompop

Hello Vincent,

First as Shinu has mentioned, please specify the exact version of the controls that you are using and whether your are using the classic controls or the Ajax suit.

Lately there has been a new security update released by Microsoft which affects the normal workflow of the drop-down lists. So far we have managed to reproduce this issue locally, but only with our classic controls for ASP.NET, but not with the new one for ASP.NET Ajax.

If you are using the RadComboBox from the Ajax suit and you experience the same problem with the latest official version of the controls, please open a support ticket and provide a runnable sample page with the issue being reproduced. You cooperation will be highly appreciated.

Best wishes,
