Come posso utilizzare queryverride in CQWP durante la distribuzione dell'istanza della web part utilizzando Elements.xml?

Question

Ho bisogno di usare il CQWP con più di tre filtri, quindi utilizzerò la queryverride con una query caml come descritto qui .Non riesco a far funzionare questo quando si distribuisce l'istanza della web part usando elementi.xml i.e. ALLUSERSERSWEBPART e CDATA.

Il modo in cui l'ho fatto con i filtri normali era come quanto segue (da elementi.xml)

<AllUsersWebPart ID="FindingsCQWP" WebPartZoneID="Middle" WebPartOrder="1" >
          <![CDATA[
            <webParts>
              <webPart xmlns="http://schemas.microsoft.com/WebPart/v3">
                <metaData>
                  <type name="Microsoft.SharePoint.Publishing.WebControls.ContentByQueryWebPart, Microsoft.SharePoint.Publishing, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
                  <importErrorMessage>Cannot import this Web Part.</importErrorMessage>
                </metaData>
                <data>
                  <properties>
                    <property name="GroupBy" type="string" />
                    <property name="FilterValue2" type="string">Draft</property>
                    ... and so forth...

.

Comunque QueryverRide richiede anche usando CDATA .Il problema è che non penso che 'nidificato' sono consentiti gli elementi CDATA.Ho provato codifica HTML la camm come una soluzione alternativa /approccio, ma inutilmente.

Qual è la soluzione qui?Immagino che potrei scrivere un codice ricevitore funzionalità, ma mi piacerebbe evitarlo se posso.

@Andrey's response pinpointed me to the answer of this question. The Query needs to be Encoded. I tried that in my initial approach, but I must have missed something.

I had this CAML that I wanted to have in my QueryOverride

<Where>
  <And>
     <And>
        <Or>
           <Eq>
              <FieldRef Name='Status' />
              <Value Type='Choice'>Not Started</Value>
           </Eq>
           <Eq>
              <FieldRef Name='Status' />
              <Value Type='Choice'>Not Closed</Value>
           </Eq>
        </Or>
        <Leq>
           <FieldRef Name='TargetImplDate' />
           <Value Type='DateTime'>
              <Today />
           </Value>
        </Leq>
     </And>
     <Eq>
        <FieldRef Name='Category' />
        <Value Type='Choice'></Value>
     </Eq>
  </And>
</Where>
<OrderBy>
  <FieldRef Name='ProcessChoice' />
  <FieldRef Name='TargetImplDate' />
</OrderBy>

Using CDATA when I added the web part to the web part gallery, and adding it to the page and exporting it afterwards got the result

<property name="QueryOverride" type="string">&lt;Where&gt;&lt;And&gt;&lt;And&gt;&lt;Or&gt;&lt;Eq&gt;&lt;FieldRef Name='Status' /&gt;&lt;Value Type='Choice'&gt;Not Started&lt;/Value&gt;&lt;/Eq&gt;&lt;Eq&gt;&lt;FieldRef Name='Status' /&gt;&lt;Value Type='Choice'&gt;Not Closed&lt;/Value&gt;&lt;/Eq&gt;&lt;/Or&gt;&lt;Leq&gt;&lt;FieldRef Name='TargetImplDate' /&gt;&lt;Value Type='DateTime'&gt;&lt;Today /&gt;&lt;/Value&gt;&lt;/Leq&gt;&lt;/And&gt;&lt;Eq&gt;&lt;FieldRef Name='Category' /&gt;&lt;Value Type='Choice'&gt;&lt;/Value&gt;&lt;/Eq&gt;&lt;/And&gt;&lt;/Where&gt;&lt;OrderBy&gt;&lt;FieldRef Name='ProcessChoice' /&gt;&lt;FieldRef Name='TargetImplDate' /&gt;&lt;/OrderBy&gt;</property>

which worked as expected. Thanks @Andrey

Answer 2

Kind of workaround, but still: deploy CQWP without this property to a page, set the property programmatically, and then export webpart to .webpart file.

I anticipate some kind of double HTML encoding nightmare like as a result.

P.S. Not tested.

P.S.S. If you will not be able to export the webpart from browser, try using programmatic approach (ExportWebPart method of SPLimitedWebPartManager).

Please keep in mind that

<where> or &lt;Where&gt;

tag should go on the same line with

<property name="QueryOverride" type="string">

like this

 <property name="QueryOverride" type="string">&lt;Where&gt;
        &lt;Or&gt;
          &lt;Eq&gt;
            &lt;FieldRef Name="AssignedTo"/&gt;
            &lt;Value Type="User"&gt;
              &lt;UserID/&gt;
            &lt;/Value&gt;
          &lt;/Eq&gt;
          &lt;Membership Type="CurrentUserGroups"&gt;
            &lt;FieldRef Name="AssignedTo"/&gt;
          &lt;/Membership&gt;
        &lt;/Or&gt;
      &lt;/Where&gt;</property>

and NOT like this

 <property name="QueryOverride" type="string">
     &lt;Where&gt;
        &lt;Or&gt;
          &lt;Eq&gt;
            &lt;FieldRef Name="AssignedTo"/&gt;
            &lt;Value Type="User"&gt;
              &lt;UserID/&gt;
            &lt;/Value&gt;
          &lt;/Eq&gt;
          &lt;Membership Type="CurrentUserGroups"&gt;
            &lt;FieldRef Name="AssignedTo"/&gt;
          &lt;/Membership&gt;
        &lt;/Or&gt;
      &lt;/Where&gt;
</property>
