# <xmod:IfEmpty>

(New to version 4.2) The IfEmpty tag is a quick way to display content only if there is no value in a column. In other words if the value is an empty string ("") or a Null value, then the content of the IfEmpty tag will be rendered out to the page.

# Syntax

<xmod:IfEmpty 
    Value="string">

...Content Goes Here...
</xmod:IfEmpty>

# Remarks

  • Value: This can be a hard-coded string value theoretically, however, the main purpose is to accept a Field Token. NOTE, when using a Field Token, you must use single quotes rather than double quotes to delimit it:
    <xmod:IfEmpty Value='[[MyField]]'>...</xmod:IfEmpty>

# Example
















 
 
 
















<div>
  <table width="100%">
    <tr>
      <td width="250" valign="top">

        <!-- EMPLOYEES TEMPLATE -->

        <xmod:Template Id="Employees">
          <DetailDataSource CommandText="SELECT * FROM XMPDemo_Employees WHERE EmployeeId = @EmpID">
            <Parameter Name="EmployeeId" Alias="EmpID" />
          </DetailDataSource>

          <DetailTemplate>
