Show ValidationSummary MVC33 as “alert-error” Bootstrap

[XNcarli]

I want to show a ValidationSummary mcv3 with "alert-error" Bootstrap styling.I'm using a Razor view, and I show model errors with this code:\[code\] @Html.ValidationSummary(true, "Errors: ")\[/code\]It generates HTML code like this:\[code\]<div class="validation-summary-errors"> <span>Errors:</span> <ul> <li>Error 1</li> <li>Error 2</li> <li>Error 3</li> </ul></div>\[/code\]I tried with this too:\[code\]@Html.ValidationSummary(true, "Errors:", new { @class = "alert alert-error" }) \[/code\]and it works ok, but without the close button (X)It generates HTML code like this:\[code\]<div class="validation-summary-errors alert alert-error"> <span>Errors:</span> <ul> <li>Error 1</li> <li>Error 2</li> <li>Error 3</li> </ul></div>\[/code\]but Bootstrap alert should have this button into the div:\[code\]<button type="button" class="close" data-dismiss="alert">
