Filter Multi Checkboxes w/ LoadSettings

[Alex]

re: https://demos.telerik.com/aspnet-mvc/grid/filter-multi-checkboxes

 

Is there a way to do filtering with check boxes but via LoadSettings? There does not seem to be a property in 'Field' that corresponses to 'Multi'

[Stefan]

Hello Alex,

I can assume that with LoadSettings means that the Grid will be loaded with a JSON formatted setting coming from the server for example.

If this is the case, then the multi property is set via columns[i].filterable.multi = true.

A similar format can be observed in our jQuery demo:

http://demos.telerik.com/kendo-ui/grid/filter-multi-checkboxes

If my assumption is not correct, please provide more details about the scenario and I will gladly assist.

No, I am using the Razor function, wee below. "Model.Columns" is a list of objects that descend from "GridColumnSettings". GridColumnSettings does not contain a property called Filterable. The only thing filter related it contains is called "FilterUIRole", which is an enum. It seems the value I want to set doesn't even exist.

@(Html.Kendo().Grid<dynamic>()
    .ToolBar(toolBar =>
    {

        toolBar.Template(
            @<text>
                @Helpers.ToolbarTemplate(this, Model)
            </text>
            );
    })
    .Name(gridName)
    .Columns(columns => {
        columns.Select().Width(50);
        columns.LoadSettings(Model.Columns);
    })

Hello Alex,

Thank you for the clarification.

Indeed, not all of the properties are available when using the LoadSettings option.

I logged an issue in our GitHub repository for adding all of the other options.

In the meantime, I can suggest using the other approach for setting the column options:

.Columns(columns => {
    columns.Bound(p => p.OrderID).Filterable(false);
    columns.Bound(p => p.Freight);
    columns.Bound(p => p.OrderDate).Format("{0:MM/dd/yyyy}");
    columns.Bound(p => p.ShipName);
    columns.Bound(p => p.ShipCity);
})

Apologies for the inconvenience this may have caused you.

Can I get some more information about that "issue", i.e. priority, status, etc?

I need to use the LoadSettings method because we have a re-usable grid control that we built using the kendo grid.The alternative is not doable.

I have landed here after stumbling on the same issue. It seems the LoadSettings way does not support all of the features in the column configurator.

In my case we had a grid with a variable number of columns (generated dynamically) and that was why using the "normal" way wasn't an option.

Here is how I got around it:-

1. Extended the GridColumnSettings class to accommodate the extra features I wanted.

2. Instead of passing the List<GridColumnSettings> to the .LoadSettings method, iterated through the new list and used the "normal" way to configure the columns. Something like this:

[...]

.Columns(columns => {

    foreach(CustomGridColumnSettings column in Model.ColumnSettings)
    {
        columns.Bound(column.Member)
        .Width(column.Width)
        .Title(column.Title)
        .ClientTemplate(column.ClientTemplate)
        .IncludeInMenu(column.IncludeInMenu)
        .Hidden(column.Hidden)
        .Sortable(column.Sortable)
        .Filterable(f => f.Enabled(column.Filterable).Multi( column.FilterableMulti ) );
    }

})

[...]
