    [CLOSED] Migrating from Ext.net 2.5 to Ext.net 4.1: ImageCommandColumn

    Hello,

    I finally decided to migrate a big application from Ext.net 2.5 to Ext.net 4.1.

    After several hours The application works but many things still are not going.

    <ext:ImageCommandColumn ID="ImageCommandColumn4" Text="" runat="server" Width="30" Resizable="false" Sortable="false" MenuDisabled="true">
        <Commands>
            <ext:ImageCommand Icon="Comment" CommandName="Comment" ToolTip-Title="Field description" ToolTip-Text="No comments about EBS row" Style="margin-left:5px !important; margin-top:2px !important; margin-bottom:2px !important;" />
        </Commands>
    
        <Listeners>
            <Command Handler="#{GridPanelEBS_Pull}.getSelectionModel().select(record.index);" />
        </Listeners>
    </ext:ImageCommandColumn>
    record.index not exist.

    Where can I find the list of parameters, for example for the Listener Command of the ImageCommandColumn object?

    thank you.

    Hello @ADV!

    The best way to determine what's available for you during an event handler is adding a breakpoint to the handler. You can set the handler as just something like console.log('test'), load the page, open the resource (ext-init-js is shown in Chrome), then place the breakpoint.

    When you place the breakpoint you can already see in the generated script, the function parameters. When the script stops on the breakpoint, you can expand the local variables and explore the available information at that time.

    You can also open sources, under src/Events/Listeners/<class>.cs and find the event there. The ListenerArgument attribute shows you the arguments the listener is supposed to support.

    If still stuck, try wrapping a simple example exploring the listener and its parameters. With that simplified code, if you still can't find by yourself, share the sample and we'll run it & provide you with more accurate advice.

    please can you tell me how this code

    <Listeners>
        <Command Handler="#{GridPanelEBS_Pull}.getSelectionModel().select(record.index);" />
    </Listeners>
    works in Ext.net 4.0?

    Solved,

    new Command handler signature is (item, command, record, recordIndex, cellIndex)

    where record object is changed and have not the index property.


    New working code is :

    <Listeners>
        <Command Handler="#{GridPanelEBS_Pull}.getSelectionModel().select(recordIndex);" />
    </Listeners>

    Do you Need an example to answer the question:

    How do I get the record index during the command event handler of ImageCommandColumn object with ext.net 4?


    ok, I'll remember the next time!

    Answer:

    Use recordIndex parameter.

    Hello ADV,

    The recommended way in ExtJS to find the record index is using store.indexOf(record).

    The recordIndex param works, although searching the Store by .indexOf is more "official".

    I believe record.index stopped working because Sencha considered the .index property as private or internal. They removed that property.

    The following example is a utility for searching Ext.NET components for their DirectEvent & Listener Arguments:

    http://examples.ext.net/#/Events/Listeners/Arguments/

    Hope this helps.

    As always your explanations are precise and they solve the problems.

    >The recommended way in ExtJS to find the record index is using store.indexOf(record).

    Certainly I will follow your advice!


    I had not seen the very useful utility for searching Ext.NET components for their DirectEvent & Listener Arguments.

    It is exactly what I needed


    As always, thank you so much

    Alessandro
