Text Issue on RadComboBox using MarkFirstMatch

[Jacques]

Hi Telerik Team,

I am using a rad combo box with MarkFirstMatch property.and i used to bind  the rad combobox  with different  countries name using ID="ddlCountry" . I used this same ID="ddlCountry " in various asp.net pages.
 <telerik:RadComboBox ID="ddlCountry" ExpandDirection="Down" runat="server"
                              MaxHeight="300px" Width="120px" DropDownWidth="150px"
                              AllowCustomText="false"   MarkFirstMatch="true" >
  </telerik:RadComboBox >
But when i start typing in that Rad Combobox,it works fine until i type the second character of country but when i typed the third character the existing values are getting erased and only the third character which i typed comes to first position and its MarkFirstMatch property is not working properly.

first i can try to bind  the rad combobox using code behind methods  with different  countries name and then  i also try to bind it with  the hard coded items values with different  countries name using ID="ddlCountry" .( Which Gives me Same Results)

But this problem is resoved when i simply changed the ID of rad combobox e.g
 <telerik:RadComboBox ID="ddlCountries" ExpandDirection="Down" runat="server"
                              MaxHeight="300px" Width="120px" DropDownWidth="150px"
                              AllowCustomText="false"   MarkFirstMatch="true" >
  </telerik:RadComboBox >
and its MarkFirstMatch property works fine...and it is happening for some specific keywords like ddlCountry, ddlState etc.
I am not sure what's the exact reason behind it??? My current telerik radcontrols version is 2011.1.1.519.35

Please Help.

Hello Jacques,

Breaking the MarkFirstMatch of the RadComboBox in the described way, is a known behavior to us. We have published an article on this matter, which provides a temporary solution to this problem. You could find it here : MS Update Breaks Combo's MarkFirstMatch.

There is an  "Additional Note" of the article linked above which should be taken into consideration.

Best wishes,
