Gets or sets a value that indicates whether to render the table header <th> HTML element for the day headers instead of the table data <td> HTML element.
Assembly: System.Web (in System.Web.dll)
The table header <th> HTML element is used for day header cells by default. You can revert to the .NET Framework version 1.0 behavior of using <td> elements for day header cells by setting this property to false.
Note that changing this value can affect scripts that rely on the rendering behavior of the version 1.0 edition of this control. The use of the <th> element might also alter the visible rendering of the Calendar control in browsers by making the day header cells center-aligned and bold.
