Click on combobox and load record

[Fabio Cirillo]

hi,
I would like that even after selecting an item, when I click on radcombobox I appeared throughout the item list also .. but after setting the filter property in StartsWith, every time I load I want to change the selected item, I must first delete the selected item so that I can look through the list .... There is a procedure that ancestral delete the selected item but also to view the entire list of items loaded into radcombo?

my code is:

<telerik:RadComboBox ID="Regione" Runat="server" CollapseDelay="100"
EnableLoadOnDemand="True" HighlightTemplatedItems="True" IsCaseSensitive="True"
LoadingMessage="Loading..." DropDownWidth="160px" Filter="StartsWith" Width="160px"
MaxHeight="175px" ShowMoreResultsBox="True" Height="175px" OnClientItemsRequesting="OnClientItemsRequesting"
AutoPostBack="True" OnSelectedIndexChanged="Regione_SelectedIndexChanged" OnClientItemsRequested="OnClientItemsRequested"
EmptyMessage="Select region" Skin="Sunset">
</telerik:RadComboBox>

Hi,

In order to achieve the desired functionality, the OnClientDropDownOpening client-side event should be handled and the following implementation of the event handler function could be used:

function OnClientDropDownOpening(sender, eventArgs) {
    if (sender.get_selectedItem()) {
        sender.set_text("");
    }
}

With the above implementation when the drop down is opening and there is already a selected item, the text of the RadComboBox will be cleared thus causing a new request for items to be made.

All the best,

ok but I would like to open my radcombobox, the text remains, but appears in the list with all the items according to the initial property startwith then starting from the selected item, and pointing out all those who follow.

my code is

<telerik:RadComboBox ID="Categoria" Runat="server" CollapseDelay="100" OnClientItemsRequesting="OnClientItemsRequesting"
    DropDownWidth="350px" EnableLoadOnDemand="True" Filter="StartsWith" OnClientItemsRequested="OnClientItemsRequested"
    HighlightTemplatedItems="True" IsCaseSensitive="True"
    LoadingMessage="Caricamento..." MaxHeight="175px"
    ShowMoreResultsBox="True"
     Width="350px" Height="175px">
</telerik:RadComboBox>

Hi,

In order to show all records and not only the filtered results upon drop down opening, a request with empty text should be performed.
