[Solved] Customize Default Behaviors of Telerik Controls

[Jeff]

Hi - Is there a way to customize the default behaviors of the Telerik controls (on app startup, or via some sort of configuration)?  

I'd like to set application-wide defaults for control features/behaviors, such as disabling spinners on a CurrencyTextBox, or setting the filter style on a ComboBox, to promote consistency throughout the application.   I realize we can adjust them on each control, but it would be great if we could adjust the default options (almost like a template or style), then only override them if/when necessary.

Thanks,

Jeff

Hi Jeff,

 There is no built-in support, but you can easily achieve that by using a custom extension method for the HtmlHelper class. For convenience I prepared a small sample that shows how to configure the Grid component. The same logic can be used with all other components.

Here are the steps:

1. Create the custom extension and set the common properties there:

namespace GridHtmlHelper.Models
{
    public static class GridHtmlHelperExtensions
    {
        public static GridBuilder<T> Grid<T>(this HtmlHelper html, IEnumerable<T> model)
            where T : class
        {
            var builder = html.Telerik().Grid(model);

            builder.Pageable();
            builder.Sortable();
            builder.Selectable();
            builder.Filterable();

            return builder;
        }

    }
}

2. Add its namespace in the web.config file as well, so it can be recognized by the framework:

<add namespace="GridHtmlHelper.Models" />

3. Use modified @{Html.Grid() in your views
e.g

@{ Html.Grid(Model)
        .Name("OrdersGrid")
        .DataKeys(keys => keys.Add("ID"))
        .Columns(columns =>
        {
            columns.Bound(o => o.ID);
            columns.Bound(o => o.Name);

        })

        .Render();
}

This way you can also override the pre-set properties - just set them to a new value in the grid's declaration.

Thanks Georgi!  That'll do exactly what we want.  Thanks for the detailed example / solution as well.
