Thank you, that was the missing bit for me!

Hi Sam,

Would you be able to post the files you made to use the MultinodeTreePicker in my data grid?

Many thanks, Daniel

Sure - I set mine up to be a "card picker" allowing people to select a number of other pages to be displayed as cards.

I created a new folder in App_Plugins called "CardContentPicker" which contained:

package.manifest

{
//you can define multiple editors
propertyEditors: [
                    {
                /*this must be a unique alias*/
                alias: "RHP.MultiCardContentPicker",
                /*the name*/
                name: "Multi Card Content Picker",
                isParameterEditor: true,
                /*the html file we will load for the editor*/
                editor: {
                            view: "~/App_Plugins/CardContentPicker/cardeditor.html"
                        }
                },
]
,
//array of files we want to inject into the application on app_start
javascript: [
'~/App_Plugins/CardContentPicker/cardeditor.controller.js'
]
}

cardeditor.html

<div ng-controller="My.CardEditorController" class="umb-editor umb-contentpicker">
<ng-form name="contentPickerForm">

    <ul class="unstyled list-icons"
        ui-sortable
        ng-model="renderModel">

        <li ng-repeat="node in renderModel">

            <i class="icon icon-navigation handle"></i>

            <a href="#" prevent-default ng-click="remove($index)">
                <i class="icon icon-delete red hover-show"></i>
                <i class="{{node.icon}} hover-hide"></i>
                {{node.name}}
            </a>
            <div ng-if="!dialogEditor && model.config.showEditButton">
                <small><a href umb-launch-mini-editor="node">Edit</a></small>
            </div>
        </li>
    </ul>

    <ul class="unstyled list-icons" ng-show="true === true || renderModel.length === 0">
        <li>
            <i class="icon icon-add blue"></i>
            <a href="#" ng-click="openContentPicker()" prevent-default>
                <localize key="general_add">Add</localize>
            </a>
        </li>
    </ul>

    <!--These are here because we need ng-form fields to validate against-->
    <input type="hidden" name="minCount" ng-model="renderModel" />
    <input type="hidden" name="maxCount" ng-model="renderModel" />

    <div class="help-inline" val-msg-for="minCount" val-toggle-msg="minCount">
        You need to add at least {{model.config.minNumber}} items
    </div>

    <div class="help-inline" val-msg-for="maxCount" val-toggle-msg="maxCount">
        You can only have {{model.config.maxNumber}} items selected
    </div>
    </ng-form>
</div>

and finally cardeditor.controller.js

angular.module("umbraco").controller("My.CardEditorController", function ($scope, dialogService, entityResource, editorState, $log, iconHelper, $routeParams, fileManager, contentEditingHelper) {

    });

    //everything is loaded, start the watch on the model
    startWatch();

});

});

Inside Grid / Editors I then made a partial view called Card.cshtml where I can get the pages selected using

foreach (var pageid in Model.value.ToString().Split(',')) {
    var cardItemNode = new Node(int.Parse(pageid));

I hope that helps!

Thanks very much, Sam!

I've gone through and created the plugins folder and the files the way you described and then pasted in your code accordingly.

I couldn't get it to work. lol

The only thing I can think is the issue has to do with the Card.cshtml that you mentioned at the end. I placed it in the Views/Partials/Grid/Editors directory ...also, looking at that file, it looks incomplete. so I tried adding the braces and some markup with didn't help either.

I am DESPARATE to have a multi node picker in my Grid. I've gone so far with it that if I can't figure this out I'm going to have to revert back to not using the grid. (waste of time)

hahaha my poor mother's site has been taking ages! lol

I learned a lot from reading your code though!

Many thanks!

Daniel

PS - I'll spend some time and try to figure out what I did wrong.

Ooh yes - You'll need to add in some new settings in \Config\grid.editors.config.js

{
"name": "Multi Page Picker",
"alias": "multipicker",
"view": "/app_plugins/GridContentPicker/gridcardeditor.html",
"icon": "icon-thumbnail-list",
"render": "/Views/Partials/Grid/Editors/Card.cshtml"
}

This tells the grid picker where to look for the editor, and how to render the control.

And a full Card.cshtml might look something like:

@model dynamic
@using umbraco.NodeFactory
@using Umbraco.Web.Templates

@{
foreach (var pageid in Model.value.ToString().Split(',')) {
    var cardItemNode = new Node(int.Parse(pageid));
    <div class="row card-item">
        <div class="col-md-12">
            <h3>@cardItemNode.Name</h3>
        </div>
    </div>
    }
}

Hi Sam,

that last bit was really helpful.

The js config file was the missing bit. thank you!

I updated the filepaths to match your original file names which worked.

when I choose the picker in the grid's cell. It loads the html file, but when I click the +Add, the page just refreshes. Sorry if I'm taking up your time.

I've also uploaded a video so you can see what I'm doing: My Video Demo

I'm soo close I just can't give up yet!

Could it be that the click event that calls the openContentPicker isn't being picked up?

Also, there are no settings to set the min and max, so is there another file or should I add the config information for these? Or could it be the "localize key"?

            <a href="#" ng-click="openContentPicker()" prevent-default>
                <localize key="general_add">Add</localize>
            </a>

Kind regards, Daniel
