[1.0] MultiCombo trigger question

[steve.redmon]

Hi, I'm very new to the coolite toolkit (and very impressed I might add).

I'm doing some testing and was wondering if I could get some light on something.
In the below server codebehind, I'm unable to hide/show a trigger. Is there something I'm missing?

<!-- multicombo markup -->
<ext:MultiCombo ID="Multi1" runat="server" Width="260">
    <Triggers>
        <ext:FieldTrigger Qtip="Select All" Tag="select_all" Icon="SimpleAdd" />
        <ext:FieldTrigger Qtip="Clear All" Tag="clear_all" Icon="Clear" HideTrigger="true" />
    </Triggers>
    <DirectEvents>
        <TriggerClick OnEvent="MultiCombo_TriggerClicked">
            <ExtraParams>
                <ext:Parameter Name="Tag" Value="tag" Mode="Raw" />
            </ExtraParams>
        </TriggerClick>
    </DirectEvents>
    <Items>
        <ext:ListItem Text="Item 1" Value="1" />
        <ext:ListItem Text="Item 2" Value="2" />
        <ext:ListItem Text="Item 3" Value="3" />
        <ext:ListItem Text="Item 4" Value="4" />
        <ext:ListItem Text="Item 5" Value="5" />
    </Items>
</ext:MultiCombo>

<!-- server side codebehind -->
<script runat="server">
Public Sub MultiCombo_TriggerClicked(ByVal sender As Object, ByVal e As Ext.Net.DirectEventArgs)
    Dim objMC As MultiCombo = sender
    Select Case e.ExtraParams("Tag")
        Case "clear_all"
            objMC.Clear()
            objMC.Triggers(0).HideTrigger = IIf(objMC.Triggers(0).HideTrigger, False, True)
            objMC.Triggers(1).HideTrigger = IIf(objMC.Triggers(0).HideTrigger, False, True)
        Case "select_all"
            objMC.SelectAll()
            objMC.Triggers(0).HideTrigger = IIf(objMC.Triggers(0).HideTrigger, False, True)
            objMC.Triggers(1).HideTrigger = IIf(objMC.Triggers(0).HideTrigger, False, True)
        End Select
End Sub
</script>

Thanks for the great tools!!

Hi,

Use ShowTrigger/ConcealTrigger methods of the trigger field

[steve.redmon]

Thank you very much, changed code and worked like a charm.

Select Case e.ExtraParams("Tag")
Case "select_all"
    objMC.SelectAll()
    objMC.ShowTrigger(1)
    objMC.ConcealTrigger(0)
Case Else
    objMC.Clear()
    objMC.ShowTrigger(0)
    objMC.ConcealTrigger(1)
End Select

just for grins, i also tested with listeners, and came up with this:

<%-- added to the multicombo --%>
            <Listeners>
                <TriggerClick Fn="triggerHandler" />
            </Listeners>

<%-- added to script block client side --%>




var triggerHandler = 
    function(el, trigger, index) {
        ddl = el;
        switch (index) { 
            case 0:
                ddl.triggers[0].hide();
                ddl.triggers[1].show();
                ddl.selectAll(); 
                break;
            case 1: 
                ddl.triggers[1].hide();
                ddl.triggers[0].show();
                ddl.clear(); 
                break;
        } 
    }

thanks for clarification on this, you can mark as solved/resolved.
