How many interrelated pieces need to be changed when a model is changed in MVC Telerik Reporting?

[Clay]

So with html/razor code in the View like so:

            <tr id="trBeginDate">
                <td>
                </td>
                <td>
                    @Html.LabelFor(m => m.BeginDate)
                </td>
                <td style="padding-right: 20px;">
                    @Html.TextBoxFor(m => m.BeginDate, new { alt = "date-us", style = "width: 164px;" })
                </td>
                <td>
                    @Html.LabelFor(m => m.BeginTime)
                </td>
                <td style="padding-right: 20px;">
                    @Html.TextBoxFor(m => m.BeginTime, new { style = "width: 109px;" })
                </td>
            </tr>

...does the TextBoxFor() construct/syntax perform two-way binding to the model? That is to say, does this assign the values entered into the textboxes thus generated to the BeginDate and BeginTime model members? I assume so; just want to verify.

Now, to combine the Date and Time values I want to pass into one control, I imagine I can replace the BeginDate and BeginTime on the model with a BeginDateTime, and then change the code above to:

            <tr id="trBeginDate">
                <td>
                </td>
                <td>
                    @Html.LabelFor(m => m.BeginDateTime)
                </td>
                <td style="padding-right: 20px;">
                    @Html.TextBoxFor(m => m.BeginDateTime, new { alt = "date-us", style = "width: 164px;" })
                </td>
            </tr>

...right? But...how do I change the associated Telerik code, which presumably is expecting a Date and a Time, not a combined DateTime?

BTW, I tested using "format code block" for the snippets above, but the preview looked like Dallas warmed over.
