The syntax supported is similar to the one used in Microsoft Excel®.</p> <p>You can use all the usual logical operators (=, >, <,.<>, >=, <=), arithmetic (+, -, *, /, ^), and you can group expressions using parentheses. For example:</p> <p> "1+2*3 < (1+2)*3" returns TRUE (7 < 9).</p> <p>Any public properties in the binding source object can be used in expressions as well. For example:</p> <p> "Price * 8.5%" returns the value of the <b>Price</b> property times 0.085.</p> <p>Properties that return collections or dictionaries are also supported. For example, assuming the <b>DataContext</b> object has a <b>Children</b> property:</p> <p> "Children(Children.Count-1).Name" returns the name of the last child.</p> <p>Finally, the <strong>C1CalcEngine</strong> supports a subset of the functions available in Excel. See <a href="C1Binding_Expression_Syntax_Elements.html">C1Binding Expression Syntax Elements</a> for a list of these functions.</p> <p> </p><!--DXMETADATA end--> <a name="seealsobookmark"></a> <!--DXMETADATA start type="FilteredItemList" scrap="CATEGORISED_LINKS" namespace="linkcategory" source="Item" filter="" NoHeader="True" NoFooter="True" format="%%replaceinquotes:value=false%%%%scrap:name=_COLLAPSIBLE_HEADER,idprefix=seealso,caption=""%%phrase:name=SeeAlso%%%%designlist:tagidentifier=seealso,itemtype=See Also%%""%%%%filtereditemlist%%</div>"--><!--DXMETADATA end--> </div> <div id="FooterContent"> <!--DXMETADATA start type="Scrap" condition="communityenabled" name="_COMMUNITY_FOOTER" --><!--DXMETADATA end --> <!--DXMETADATA start type="Variable" name="CopyrightNotice" format="<p> </p><p> </p><hr style=""height: 1px"" /><p>%%variable%%</p>" --><p> </p><p> </p><hr style="height: 1px"><p>Copyright (c) <script type="" text/javascript""=""> var theDate=new Date() document.write(theDate.getFullYear()) </script> GrapeCity, inc.
