Content search WebPart is used to fetch the data but it is fully depending on the Crawl. I mean to say, that the data will be available to the content search WebPart after crawl gets completed. In one of our requirement we had to fetch the data real time, so we decided to use Content Query WebPart.

Let see how we can fetch the data by using Content Query Webpart.

First let’s add 5 site columns named as EmpName, EmpEmail, EmpDept, EmpSalary & Emp Check

Create a list named as CQWebPartList

Add the 5 site columns to the newly created list & add few data into the list

Now create a SharePoint site page named as CQWebPartPage

Add a content query WebPart within the newly created page, Edit WebPart & add title as My Content Query.

Under query select the created list

Select the list type as below

Now export the content query WebPart

Create a sandbox solution

Add a module within the sandbox solution named as CQWebPartModule

Add the exported content query WebPart file under CQWebPartModule module

Go to the Style library — > XSL Style Sheet

Download the default main & Item Style XSL files named as: ContentQueryMain & ItemStyle

Rename the downloaded XSL file as CQMain & CQItemStyle respectively. Add the files to the solution under a newly created folder named as “Style Library”

Now open Content Query.webpart which we have added already under the module and modify the below properties to link with the XSL files

<property name="ItemXslLink" type="string" >/sites/Site1/Style Library/XSL Style Sheets/CQItemStyle.xsl</property>

<property name="MainXslLink" type="string" >/sites/Site1/Style Library/XSL Style Sheets/CQMain.xsl</property>

Add the following field mapping

<property name="CommonViewFields" type="string" >Title, Text;EmpName, Text;EmpEmail, Text;EmpDept, Text;Emp_x0020_Check, Text;EmpSalary</property>

Replace Elements.xml by the below code snippet

<?xml version="1.0" encoding="utf-8"?>

<Elements xmlns="http://schemas.microsoft.com/sharepoint/">

<Module Name="CQWebPartModule" Url="_catalogs/wp">

<File Path="CQWebPartModule\My Content Query.webpart" Url="My Content Query.webpart" >

<Property Name="Group" Value="Custom" />

</File>

</Module>

</Elements>

Now add the below template within CQItemStyle.xsl

 <xsl:template name="Employee-Details" match="Row[@Style='Employee-Details']" mode="itemstyle">
     <html>
       <table width="100%" cellspacing="4" cellpadding ="4">
         <xsl:if test="count(preceding-sibling::*)=0">
           <tr>
             <td width="20%" valign="top">
               <b>Title</b>
             </td>
             <td width="20%" valign="top">
               <b>Employee Name</b>
             </td>
             <td width="20%" valign="top">
               <b>Employee Email</b>
             </td>
             <td width="20%" valign="top">
               <b>Employee Department</b>
             </td>
             <td width="10%" valign="top">
               <b>Employee Salary</b>
             </td>
             <td width="10%" valign="top">
               <b>Employee Check</b>
             </td>
           </tr>
         </xsl:if>
         <tr>
           <td width="20%" valign="top">
             <xsl:value-of select="@Title" />
           </td>
           <td width="20%" valign="top">
             <xsl:value-of select="@EmpName" />
 
           </td>
           <td width="20%" valign="top">
             <xsl:value-of select="@EmpEmail" />
           </td>
           <td width="20%" valign="top">
             <xsl:value-of select="@EmpDept" />
           </td>
           <td width="10%" valign="top">
             <xsl:value-of select="@EmpSalary" />
           </td>
           <td width="10%" valign="top">
             <xsl:value-of select="@Emp_x005F_x0020_Check" />
           </td>
         </tr>
         
       </table>
     </html>
   </xsl:template>
 

The field names in these are very sensitive and if we miss _x005f in the field name will break it. Make sure to include the correct field names, which is different from internal name.

Refer the below examples for various fields.

Field NameXSL Field NameInternal Name
Vendor Description@Vendor_x005F_x0020_DescriptionVendor_x0020_Description
Go-live@Go_x005F_x002d_liveGo_x002d_live
IT HelpDesk #@IT_x005F_x0020_HelpDesk_x005F_x0020__x005F_x0023_IT_x0020_HelpDesk_x0020__x0023_

Use this in an itemstyle to output a header:

<xsl:if test="count(preceding-sibling::*)=0">

</xsl:if>

Use this in an itemstyle to output footer:

<xsl:if test="count(following-sibling::*)=0">

</xsl:if>

Add the below line of code in CQMain.xsl

<xsl:variable name="ItemStylePrefix" select="’Employee-‘" />

Rebuild the sandbox solution and deploy

Under the Style Library add the two modified XSL files

Now from the Site Page delete the WebPart and add it again

Under presentation select the Item style “Employee-Details”

Save the WebPart & the output will be looking like

clip_image010

 

Hope this artifact will help the basic use & implementation of Content query WebPart.

Happy Coding
