    [CLOSED] [1.0] ComboBox automatically clears value?

    Hi,

    I have a combo box to be used as a search input field. When I type in something on it and tick the checkbox control below it, the typed in value is erased. How can I prevent this from happening?

    <ext:Panel ID="Panel2" runat="server" Border="false" Title="Search Catalog" Height="100"  Width="450" Frame="true" LabelAlign="Right" Icon="Magnifier" CtCls="titleNormal" AutoScroll="true" BodyStyle="padding-left: 15px; padding-top: 5px;" Collapsible="false">
            <Items>
                <ext:ComboBox ID="TreatmentFilter" runat="server" EnableKeyEvents="true" HideTrigger="true" Width="400" EmptyText="Catalog Keyword Search" EnableViewState="true" CausesValidation="false" >
                    <Triggers>
                        <ext:FieldTrigger Icon="Search" HideTrigger="true" />
                        <ext:FieldTrigger Icon="Clear" HideTrigger="true" />
                    </Triggers>
                    <Listeners>
                        <BeforeQuery Handler="this.triggers[0][ this.getRawValue().toString().length == 0 ? 'hide' : 'show']();this.triggers[1][ this.getRawValue().toString().length == 0 ? 'hide' : 'show']();" />
                        <TriggerClick Handler="if (index == 0) {} else if (index == 1) { this.clearValue();  this.triggers[0].hide(); } " />
                    </Listeners>
                </ext:ComboBox>
                <ext:Checkbox ID="chkbxTreatmentAllWords" runat="server" HideLabel="true" Name="" BoxLabel="Search for All Words" LabelSeparator=""></ext:Checkbox>
            </Items>
        </ext:Panel>

    Hi Marcelo,

    Please set the ComboBox's ForceSelection property to false.

    Example
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Ext.Net Example</title>
</head>
<body>
    <form runat="server">
    <ext:ResourceManager runat="server" />
    <ext:ComboBox runat="server" ForceSelection="false">
        <Items>
            <ext:ListItem Text="Text 1" Value="Value1" />
            <ext:ListItem Text="Text 2" Value="Value2" />
            <ext:ListItem Text="Text 3" Value="Value3" />
        </Items>        
    </ext:ComboBox>
    <ext:Checkbox runat="server" />
    </form>
</body>
</html>
