Hi Azadeh,

The following definition and JavaScript related to RadComboBox works just fine at my end in all major browsers.

function clicked(sender, args) {
    var combo = $find("RadComboBox1");
    alert(combo.get_text());
}

<telerik:RadComboBox runat="server" ID="RadComboBox1">
    <Items>
        <telerik:RadComboBoxItem Text="111" />
        <telerik:RadComboBoxItem Text="222" />
        <telerik:RadComboBoxItem Text="333" />
    </Items>
</telerik:RadComboBox>
<telerik:RadButton  runat="server" Text="click" AutoPostBack="false" OnClientClicked="clicked"/>

The following help article referencing the client API of the control might be of help too: http://www.telerik.com/help/aspnet-ajax/combobox-client-side-basics.html.

Kind regards,

Hi,
My source is here.

    <telerik:RadComboBox ID="RCB" AllowCustomText="true" MarkFirstMatch="true" OnItemsRequested="RCB_ItemsRequested"
        EnableLoadOnDemand="true" runat="server" AppendDataBoundItems="true" ShowWhileLoading="true"
        ZIndex="15000" OnClientSelectedIndexChanged="EP_AddB" OnClientBlur="EP_AddB">
    </telerik:RadComboBox>

function EP_AddB(sender, args) {
        EP_Add(sender.get_id());
    }
    function EP_Add(nam) {
        var commID = nam.toString().substring(0, nam.toString().length - 4);
        $get(commID + '_LB1').options.add(new Option($find(nam).get_text(), $find(nam).get_value()));
        EP_Copy2HF($get(commID + '_HF1'), $get(commID + '_HF2'), $get(commID + '_LB1'));
        $find(nam).set_text('');
    }
In EP_AddB(sender, args) function get_id() returns value but in EP_Add(nam) get_text() returns Empty.
and this problem only occurs in Chrome.
can u check this please and let me know your idea?
thanks,
Azadeh

Hi Azadeh,

This has to do with the load-on-demand functionality and the RadComboBox not being able to find an item that matches the text typed in the input area.
You could, however, try the following approach:

function blur(sender, args) {
    alert(sender.get_text());
}

<telerik:RadComboBox ID="RCB" AllowCustomText="True" MarkFirstMatch="True"
    EnableLoadOnDemand="True" runat="server" AppendDataBoundItems="True"
    ZIndex="15000" OnClientSelectedIndexChanged="EP_AddB" OnClientBlur="blur"
    DataSourceID="SqlDataSource1" DataTextField="Name" DataValueField="ID">
</telerik:RadComboBox>

I hope this will help.
