All my childhood geek fantasies are about to come true…

For a project I’m working on now I wanted a numeric editor, something that would only allow input of digits. I found a jQuery numeric plugin that does the job. I also created a custom EditorTemplate for both decimal and int data types. For the int EditorTemplateyou have to name the file ‘Int32.cshtml’.

@model System.Int32?
@Html.TextBox("",
    (Model.HasValue) ? ViewData.TemplateInfo.FormattedModelValue : "",
    new { data_integer = true, @style = "width:90px;" })

The decimal template has the same code except the ‘data-’ attribute is data_decimal. Then in $(document).ready(function () {} I included the following code taken from the plugin template example, modified to utilize the ‘data-’ attribs that I generated in the templates.

    $(":input[data-decimal]").numeric();
    $(":input[data-integer]").numeric(false, function () { alert("Integers only"); this.value = ""; this.focus(); });
    $(":input[data-positivedecimal]").numeric({ negative: false }, function () { alert("No negative values"); this.value = ""; this.focus(); });
    $(":input[data-positiveinteger]").numeric({ decimal: false, negative: false }, function () { alert("Positive integers only"); this.value = ""; this.focus(); });
    $("#remove").click(
		function (e) {
		    e.preventDefault();
		    $(".numeric,.integer,.positive").removeNumeric();
		}
	);

I’m doing a quick one-off scheduling app for work and needed to present in the user interface the dates of the current and next three weeks’ Monday, Wednesday, and Friday. The DayOfWeek enumerator’s corresponding int values come in handy. The snippet below uses the int value of the DayOfWeek value from DateTime.Now to create an offset which is then subtracted from DateTime.Now to find the date of Sunday of the current week.

DateTime now = DateTime.Now;
int dayOfWeekOffset = (int)now.DayOfWeek;
DateTime firstDayOfWeek = now.AddDays(-dayOfWeekOffset);

From there you can add days to firstDayOfWeek to find the date of the relevant week day. For example:

//this week's Wednesday
DateTime wednesday = firstDayOfWeek.AddDays(3);
//next week's Friday
DateTime friday = firstDayOfWeek.AddDays(12);
