[CLOSED] Button functionality in a GridPanel Tool

    [CLOSED] Button functionality in a GridPanel Tool

    I'm trying to implement a button with export functionality (csv, xls, xml) inside a GridPanel Tool.

    I have an approach but it doesn't look good. Is there a way to do it?

    here is my code, the button that i'm trying to use is the one with id=ExporInTool (button with id=ButtonExport is there just to show the functionality)

    Hello @opendat2000!

    Your test case has 300+ lines... I'm just wondering, all you need is a panel tools' button with a menu? Maybe this could be represented in a simpler way, right? It does not look right to add the Content block within the tool. This usually puts layout consistency in check and requires the developer extra care to maintain the order in components, as it allows arbitrary HTML within.

    Let me know if we can work with a simple (maybe just return a messageBox or Toast from the server (or even just a listener).

    I mean, if the sample button works for you, maybe we can drop about 250 lines off the code, right? Or maybe I didn't understand your requirements yet.

    Hello, yes all i need is a panel tool with a button that can export the GridPanel data to Excel.

    Thank you for the fast answer

    Hello @Opendat2000!

    I get you already can save as you need if going by the standalone button with menu, right? So let's just focus on making the menu show by the tool button click on the panel header.

    You can copy-paste and have this running on your grid, then adapt it back to the menu the way you need it:

    <Tools>
        <ext:Tool runat="server" Type="Save" Handler="App.Menu1.showBy(this);">
            <Bin>
                <%-- Make a dangling menu that will be displayed on click by the tool --%>
                <ext:Menu ID="Menu1" runat="server">
                    <Items>
                        <ext:MenuItem ID="MenuItem1" runat="server" Icon="PageCode" Text="Exportar XML" OnClientClick="Ext.toast('save XML');">
                        </ext:MenuItem>
                        <ext:MenuItem ID="MenuItem2" runat="server" Icon="PageExcel" Text="Exportar Excel" OnClientClick="Ext.toast('save XLS');">
                        </ext:MenuItem>
                        <ext:MenuItem ID="MenuItem3" runat="server" Icon="PageAttach" Text="Exportar CSV" OnClientClick="Ext.toast('save CSV');">
                        </ext:MenuItem>
                    </Items>
                </ext:Menu>
            </Bin>
        </ext:Tool>
    </Tools>
    What's done here is a standalone menu. The menu code can be written anywhere in the page -- as long as the part is rendered by the time the grid panel is. The "special" here is just making the menu be shown by the tool when the tool is clicked, the handler in the second line of the code above.

    The Bin block is just a convenient way to wrap the menu within its ext:Tool premises, a good idea to improve readability and maintenance of the code (and you can copy over the grid with menu and all elsewhere if you need to reuse this code by old copy-paste).

    I prefered the Bin over the HtmlBin equivalent the same way I'd prefer Items over Content in components: to ensure component configuration objects and not plain HTML is dumped within the component, which can compromise layout, etc.

    I hope this helps!

    p.s.: I based the investigation in Examples Explorer's Export Data from GridPanel example.
