[CLOSED] Ext.Net MVC - MultiSelect Click or Select Event

[RajivDutt]

With reference to this example, i want to do some calculation on click/selection of an item in the Multiselect.

http://mvc.ext.net/#/Form_MultiSelect/Overview/

Please suggest which event is available for this...

Thanks,

Hi @RajivDutt,

Please use a MultiSelect's Change event.

Hi @RajivDutt,

Please use a MultiSelect's Change event.

When does the change event fire, it does not fire on click or selection of an item?
I am using version 2.3, it seems 2.2 had the click event... is it deprecated?

Thanks

It does appear the Click and DblClick events (Listeners + DirectEvent) were removed from MultiSelect between v2.2.0 and v2.3.0.

Change occurred in Svn revision #5155

Here's the comment left by Vladimir on the commit:

[UPDATE] Click and DblClick events are removed for MultiSelect, need to use events from ListConfig

I would consider this a Breaking Change, although at the moment I do not have the exact reason why this change was made.

I am are investigating.

Here's a quick sample demonstrating configuring an ItemClick Listener in WebForms markup. The same properties and events are available in both WebForms and MVC Razor.

Example

<ext:MultiSelect runat="server">
    <Items>
        <ext:ListItem Text="Item 1" Value="1" />
        <ext:ListItem Text="Item 2" Value="2" />
    </Items>
    <ListConfig>
        <Listeners>
            <ItemClick Handler="alert(arguments);" />
        </Listeners>
    </ListConfig>
</ext:MultiSelect>

It is a breaking change between v1.x and v2.0. Just a MultiSelect's Click and DblClick events stopped working because of redesigning inside the MultiSelect control, but we discovered it only in v2.2. As far as I can remember due to a member's report in the forums.

I can add the following item to BREAKING_CHANGES.txt (between v1 and v2.0).

185. The MultiSelect's Click and DblClick events have been removed. Please use the ItemClick and ItemDblClick events of its ListConfig.

Example

// Old

     <ext:MultiSelect runat="server">
         <Listeners>
             <Click Handler="alert('Click');" />
             <DblClick Handler="alert('DblClick');" />
         </Listeners>
     </ext:MultiSelect>

// New

     <ext:MultiSelect runat="server">
         <ListConfig>
             <Listeners>
                 <ItemClick Handler="alert('ItemClick');" />
                 <ItemDblClick Handler="alert('ItemDblClick');" />
             </Listeners>
         </ListConfig>
     </ext:MultiSelect>

That's funny you had some issue in v1.x but you discovered in v. 2.2 and released the patch in v2.3. So its a breaking change for 1.x to 2.2.

Not breaking change for 2.2 to 2.3. ha ha ha

Just for clarifying:

you had some issue in v1.x

There is no issue regarding it in v1.x. The Click and DblClick events should be working well there. They stopped working in v2.0 and were removed in v2.3.
