    [CLOSED] How to prevent selecting a Gridpanel row when clicking on a link that is inside that row

    Hi,

    We are using Ext.Net 2.5 version, facing one issue with hyperlink on Gridpanel. When we click on hyperlink on grid panel the row selection is losing. Example, if a row selected already, click on link the row should NOT change the selection, if row selected that should be as it is when click on Link.

    Please see the example code below and suggest the solution asap.

    Hello @iansriley!

    You code has errors, please try to run that on Visual Studio and you should easily see it. As per our More Information Required guidelines, we should be able to run your code without modification (run as much as it is necessary to reproduce the issue you're talking about) and I don't even see links inside the grid rows. Maybe you happened to copy paste the wrong test case in the initial post?

    Looking forward to your follow-up so we can help you with the issue you're facing.

    Hello @iansriley!

    Now that's more like it, the sample ran smoothly and I could find an alternative for you.

    Actually, it should be possible to do from plain javascript, but I don't think this should be the goal using Ext.NET and/or ExtJS, should it be? Specially when there's a supported feature that does that for you!

    Yes, I'm pretty confident you are looking to the command feature of a grid column. And here's how you can change the price column to have it working.

    Notice I changed the code to just show an alert message (so that it does not open a new tab) but, that's encapsulated on a full Listener, and you can enjoy all programming you can do with a listener so, I don't think you're going to find a bad limitation of sorts to it.

    <ext:Column ID="PriceColumn" runat="server" Text="Price" Width="75" DataIndex="price">
        <Renderer Handler="return '';" />
        <Commands>
            <ext:ImageCommand CommandName="DoMyClick" />
        </Commands>
        <PrepareCommand Handler="command.text='<a href=\'#\'>' + value + '</a>';" />
        <Listeners>
            <Command Handler="Ext.Msg.alert('column', 'click');" />
        </Listeners>
    </ext:Column>
    In fact, you could just let it print the values (do not add any renderer, remove line 2 on my code above), remove also the PrepareCommand line (line 6) and just use <ext:ImageCommand CommandName="DoMyClick" Icon="Link" Text="Open" />.

    When wrapped in the command concept, the row selection/deselection on the command-handled cell won't be triggered. To be more specific, the selection will not be triggered as long as the interaction is with the actual command button/image/text (not cell text, that's why I've set the code above to do the ordinary render as an empty cell).

    More on that can be found on this example: http://examples2.ext.net/#/GridPanel.../Cell_Command/

    I hope this helps!

    Hello @iansriley!

    It's been a while since we last replied you here in this thread and still no feedback from you. Do you still need help with this issue? Or rather, did our last reply help at all?

    We may mark this thread as closed if you don't reply in 7+ days from now, but that is not going to "lock up" the thread, so if you happen to be able to post a feedback only after this, it will still be okay.
