使用组合框,当展开并按字符键选择另一个值时,它显示选择值但按回车键它会缩小列表但选择最后一个值。

keypress 不支持 extjs 4 中的回车键操作。

<ext:ComboBox ID="CmbState" runat="server" StoreID="StoreState" Editable="false"
                              HideMode="Offsets" QueryMode="Local" DisplayField="Text" ValueField="Value" TypeAhead="true"
                              ForceSelection="true" TriggerAction="All" EnableKeyEvents="true" EmptyText="Select a State..."
                              TabIndex="3">
                              <SelectedItems>
                                <ext:ListItem Value="Please Select....." />
                              </SelectedItems>
                            <DirectEvents>
                                <Select OnEvent="FillDropdowns">
                                  <EventMask Msg="Updating Carriers. Please wait..." ShowMask="true" />
                                </Select>
                              </DirectEvents>
                              <Listeners>
                                <Select Handler="Combo_selectedIndexChanged(this);" />
                                <KeyDown Handler="return Combofilter(#{CmbState},'Text','Value',e);" />
                              </Listeners>
                            </ext:ComboBox>
