The If Control displays XML content based on dynamically updated criteria. For example, if you specify
<wl:if cid="-1665810327775112144" condition="online">, and if that particular CID is offline when the page loads, then the
if tag is automatically re-evaluated after the page loads.
The content of the
wl:if tag is visible for a brief period before the page loads, and this may cause a "flicker" effect each time the page loads. To avoid this, apply the
display:none style attribute to the
wl:if tag, as shown in the following example.
<wl:if cid="$user" style="display:none"> ... </wl:if>
After the tag is evaluated by the runtime engine, the
display:none style attribute is removed. However, the
wl:if tag's other style attributes remain intact and render as authored.
The following example shows the markup for inserting the If control into a Web page.
<wl:if cid="-01234456789" condition="online"> Markup to display if the condition is met. </wl:if>
