    <p>I need to round off 4 digit decimal to 2 digits and show in MVC 3 UI</p> <p><strong>Something like this 58.8964 to 58.90</strong> </p> <p>Tried following this <a href="https://stackoverflow.com/questions/5080451/how-should-i-use-editorfor-in-mvc-for-a-currency-money-type">How should I use EditorFor() in MVC for a currency/money type?</a> but not working. </p> <blockquote> <p>As i am using TextBoxFor=> i removed ApplyFormatInEditMode here. Even i tried with ApplyFormatInEditMode , but nothing works. Still showing me 58.8964.</p> </blockquote> <p>MyModelClass</p> <pre><code> [DisplayFormat(DataFormatString = "{0:F2}")] public decimal? TotalAmount { get; set; } @Html.TextBoxFor(m=&gt;m.TotalAmount) </code></pre> <p><strong><em>How can i achieve this round off?</em></strong></p> <p><strong>I can't use EditorFor(m=>m.TotalAmount) here, as i need to pass some htmlAttributes</strong></p> <p>Edit:</p> <p>After debugging with MVC source code, they internally use </p> <pre><code> string valueParameter = Convert.ToString(value, CultureInfo.CurrentCulture); </code></pre> <p>in MvcHtmlString InputHelper() method of InputExtension.cs that takes <strong>object value</strong> as parameter and converting. They are not using any display format there. How could we fix?</p> <p>I managed to fix in this way. As i have a custom helper, i can able to manage with the below code</p> <pre><code> if (!string.IsNullOrEmpty(modelMetaData.DisplayFormatString)) { string formatString = modelMetaData.DisplayFormatString; string formattedValue = String.Format(CultureInfo.CurrentCulture, formatString, modelMetaData.Model); string name = ExpressionHelper.GetExpressionText(expression); string fullName = htmlHelper.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(name); return htmlHelper.TextBox(fullName, formattedValue, htmlAttributes); } else { return htmlHelper.TextBoxFor(expression, htmlAttributes); } </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
