Render asp.TextBox for html5 input type="date"

Question

I don't know if it has been asked before, couldn't find it either.

Is it possible to control the type of the input text that is rendered by an asp:TextBox? I would like to change it to <input type="date">

any suggestions or comments are welcome, thanks

Answer 1

There is an update for .NET framework 4 which allows you to specify the type attribute

http://support.microsoft.com/kb/2468871.

See feature 3 way down the page

Feature 3

New syntax lets you define a TextBox control that is HTML5 compatible. For example, the following code defines a TextBox control that is HTML5 compatible:

<asp:TextBox runat="server" type="some-HTML5-type" />

If you don't mind subclassing, you can do this by overidding AddAttributesToRender

public class DateTextbox : System.Web.UI.WebControls.TextBox
{
    protected override void AddAttributesToRender(System.Web.UI.HtmlTextWriter writer)
    {
        writer.AddAttribute("type", "date");
        base.AddAttributesToRender(writer);
    }
}
