This section applies to the HTML Web DataWindow only. You can use XHTML templates to customize the display of the XML Web DataWindow and XHTML Web DataWindow. For more information, see Chapter 11, “Working with XHTML Templates.”
No validation
The HTML Generator does not validate the HTML you include
in controls in DataWindow objects. If the HTML is not valid, the
DataWindow might not display correctly.
You can include valid HTML in some controls in a DataWindow object, including a text control, column, or computed field. To render the contents of the control as HTML when the HTML for the DataWindow is generated, set the control’s ValueIsHTML property to true. For example, suppose a text control’s text property is <I>Name</I>. The following table shows how the text is rendered in the generated HTML and displayed in a browser.
ValueIsHTML |
Generated HTML source |
Output in browser |
|---|---|---|
TRUE |
<I>Name</I> |
Name |
FALSE |
<I>Name</I> |
<I>Name</I> |
When you embed HTML in a control, you can cause ASP to detect
a security risk. To avoid this, add validateRequest='false' in
the page directive of your ASP page.
The AppendedHTML property enables you to append your own HTML to the HTML generated by the HTML Generator component. You can use this feature to specify attributes and event actions. The HTML you specify for the AppendedHTML property value is appended to generated syntax for the rendering of a DataWindow control before the closing bracket of the HTML element for that control.
You must also make sure not to use an event handler name that is already generated for a DataWindow control as a client-side event handler. These include the names listed in the following table.
DataWindow control |
Generated event handler names |
|---|---|
Edit, EditMask, DropDownListBox, or DropDownDataWindow |
onFocus, onClick, onChange, and onBlur |
CheckBox or RadioButton |
onFocus, onClick, and onBlur |
TextBox, Picture with link, or Button |
onClick |
