You can change the look and feel of the ValidatorCallout using the ValidatorCallout CssClass property. The ValidatorCallout
has a predefined set of CSS classes that can be overridden. It has a default style
which is embedded as a WebResource and is a part of the Toolkit assembly that has
styles set for all the sub-classes. You can find the default styles in the Toolkit
solution in the
"AjaxControlToolkit\ValidatorCallout\ValidatorCallout.css" file. If your
CssClass does not provide values for any of those then it falls back to the default
value. In the example above the default style is used. To customize the same the
user would have to set the CssClass property to the name of the CSS style and define
the styles for the individual classes so that the various elements in a ValidatorCallout control
can be styled accordingly. For example, if the CssClass property was set to "CustomValidatorCalloutStyle",
this is how the css to style the border and background color would look:
.CustomValidatorCalloutStyle div,
.CustomValidatorCalloutStyle td {
border:solid 1px blue; background-color: #ADD8E6;
}
