Enhancement

Expose delegate overloads for the Dialog's Content() configuration

Overview

Currently, the Dialog does not allow setting delegate overloads, unlike its more feature-rich flavored Window counterpart.

E.g:

@(Html.Kendo().Dialog()
    .Name("dialog")
    .Content(@<text>
        <h3>Some Content</h3>
    </text>)
)
