By popular demand, some Telerik web controls such as RadInput behave like inline-block
elements, i.e. they do not force new lines on the page and at the same time, they
obey width, height and other block-level-specific CSS properties.
In addition, RadInput supports a scenario in which several HTML elements
(Label, TextBox and a Button) occupy a preset amount of space, without calculating and changing
Unfortunately, all these requirements cannot be met with the current browser CSS support and CSS
specification. That's why some of the features and functionalities are implemented at the cost of
compromising web standards - we use some CSS hacks and ignore HTML semantics by using tables.
However, Telerik constantly pursues improving the standards compliance of its web controls and thus we
created a rendering mode for RadInput and RadDateTimePicker in which no tables are used. Instead
of being rendered inside a table, now the textbox can be rendered inside a span element. The
condition is that the label and image buttons are not used.
Here is a KB article which demonstrates how to add custom labels and
image buttons and make them work like the controls' native ones. We added this standard-compliant
rendering feature very short time before Q3 2007 SP1 was released (on January 14, 2008), and we
found a couple of issues related to HTML validation afterwards. That is why the attached project
runs with custom build assemblies of RadInput for ASP.NET and RadControls Prometheus. If anyone
would like to obtain developer versions, please contact our Support team.
