Hi Vishmay,

As a work around please do the following modification in your OnClientKeyPressing event.

JavaScript:
function OnClientKeyPressing(sender, e) {
    if (e.get_domEvent().keyCode != 9) {
        if (!sender.get_dropDownVisible())
            sender.showDropDown();
    }
    else {
        sender.findItemByText(sender._text.toUpperCase()).select();
    }
}

Thanks,
Shinu.

Your answer is correct for my given case.
But not possible to implement.
Point 1:
That items may come from database.
So instead of ITEM0,1,2
What if Itemlist is
 Item0
ITEM1
IteM2

Point 2:
Onclicking Tab from dropdown it is not selecting value if case is different
but it is not also closing combobox

Very Tricky line i have written so i will explain with steps and screens
1. Have 3 Items : ITEM1,2,3 and typing item1 works
2. Changed item name ItEm1,2,3 and typing item1 not working(as it was expected). But
3. On Pressing Tab the combobox suggesion list remains open.
Note: Check Focus on attached file "2. Mix case not working solution After Tab.JPG"
In previous example i have posted was closing the combobox
the problem will be found when you will type "people" in item list ItEm1,2,3---> Not Found Press tab
and combobox remains open without any reason. and combobox text is also not clearing
Thank You

Hello Vishmay,

I would suggest you a slightly different approach. You could set the MarkFirstMatch property of the RadComboBox to true. Thus, at the OnClientTabSelecting client-side event of the control, you could use the get_highlightedItem() function and set the returned item as selected. I have prepared a sample example for you, which you may find attached.

Regards,
