KeyNotFoundException from jQWidgets Tag Helpers when following documentation steps #2

Closed DrEsteban closed 6 years ago

DrEsteban commented 6 years ago

Hello,

I'm trying to follow the initial steps to create a new project here: https://www.jqwidgets.com/asp.net-core-mvc-tag-helpers-documentation/

I'm trying to get a jqx-grid going with some simple data. But every time I load the View that has the jqx-grid, I'm getting a KeyNotFoundException.

Any tips would be greatly appreciated.

Html:

@model IEnumerable<Models.Query.EventQueryEntry>
@{
    ViewData["Title"] = "Queries";
}

<h2>Queries</h2>

<section>
    <h4>Trigger Query</h4>
    <button id="triggerQuery">Trigger</button>
</section>

<section>
    <h4>Query List</h4>
    <span>@Model.First().QueryIdStr</span>
    <jqx-grid auto-height="true" width="850" source="Model">
        <jqx-grid-columns>
            <jqx-grid-column datafield="QueryIdStr"></jqx-grid-column>
        </jqx-grid-columns>
    </jqx-grid>
</section>

Controller method:

public async Task<IActionResult> Queries()
        {
            //return View(await this._storageManager.ListQueriesAsync());
            await Task.CompletedTask;
            return View((IEnumerable<EventQueryEntry>)new[]
            {
                new EventQueryEntry("Test"),
                new EventQueryEntry("Test")
            });
        }

Model:

public class EventQueryEntry
{
    public EventQueryEntry(string str)
    {
        QueryIdStr = str;
    }

    public string QueryIdStr {get; set;}
}

Thanks for the feedback. The error should be resolved in ver. 2.0.1 which is now available.

Thanks! Yes 2.0.1 fixed this issue for me.
