Content Query Webpart and Data View Webpart – Modal Dialogs

Requirement

We have a content query webpart that displays information from a list on a subsite. When a user clicks on a link on the webpart, we want the link to open in a Modal dialog.

Solution

1. Open SharePoint Designer 2010
2. Go to All Files -> Style Library -> XSL Style Sheets -> ItemStyle.xsl -> Modify
3. Copy one of the existing templates, e.g. Default, change the name and modify the XSL according to your needs.

Here is a simple example, that I created for ‘Job Vacancies’.

Note the bits in blue where javascript is used to force the links to open in a dialog window.

<xsl:template name=”JobVacancy” match=”Row[@Style='JobVacancy']” mode=”itemstyle”>

<xsl:variable name=”Created”>

<xsl:value-of select=”ddwrt:FormatDateTime(string(@Created) ,1033 ,’dd/MM/yyyy’)” />

</xsl:variable>

<xsl:variable name=”_DCDateCreated”>

<xsl:value-of select=”ddwrt:FormatDateTime(string(@_DCDateCreated) ,1033 ,’dd/MM/yyyy’)” />

</xsl:variable>

<xsl:variable name=”SafeLinkUrl”>

<xsl:call-template name=”OuterTemplate.GetSafeLink”>

<xsl:with-param name=”UrlColumnName” select=”‘LinkUrl’”/>

</xsl:call-template>

</xsl:variable>

<xsl:variable name=”SafeImageUrl”>

<xsl:call-template name=”OuterTemplate.GetSafeStaticUrl”>

<xsl:with-param name=”UrlColumnName” select=”‘ImageUrl’”/>

</xsl:call-template>

</xsl:variable>

<xsl:variable name=”DisplayTitle”>

<xsl:call-template name=”OuterTemplate.GetTitle”>

<xsl:with-param name=”Title” select=”@Title”/>

<xsl:with-param name=”UrlColumnName” select=”‘LinkUrl’”/>

</xsl:call-template>

</xsl:variable>

<xsl:variable name=”LinkTarget”>

<xsl:if test=”@OpenInNewWindow = ‘True’” >_blank</xsl:if>

</xsl:variable>

<div id=”linkitem” class=”item”>

<xsl:if test=”string-length($SafeImageUrl) != 0″>

<div class=”image-area-left”>

<a href=”{$SafeLinkUrl}” target=”{$LinkTarget}” title=”{$DisplayTitle}”>

<xsl:value-of select=”$_DCDateCreated”/> – <xsl:value-of select=”$DisplayTitle”/>

</a>

</div>

</xsl:if>

<div class=”link-item”>

<xsl:call-template name=”OuterTemplate.CallPresenceStatusIconTemplate”/>

<script type=”text/javascript”>

function ModalDialog(url) {

var options = {

url: url,

title: “Job Vacancies”,

allowMaximize: true,

showClose: true,

width: 800,

height: 600,

dialogReturnValueCallback: silentCallback};

SP.UI.ModalDialog.showModalDialog(options);

}

function silentCallback(dialogResult, returnValue) {

}

function refreshCallback(dialogResult, returnValue) {

SP.UI.Notify.addNotification(‘Operation Successful!’);

SP.UI.ModalDialog.RefreshPage(SP.UI.DialogResult.OK);

}

</script>

<a href=”javascript:ModalDialog(‘{$SafeLinkUrl}’)” target=”{$LinkTarget}” title=”{$DisplayTitle}”>

<xsl:value-of select=”$_DCDateCreated”/> – <xsl:value-of select=”$DisplayTitle”/>

</a>

<div class=”description”>

<xsl:value-of select=”@Description” />

</div>

</div>

</div>

</xsl:template>

You can also use the same bit of code to force links in your data view web part to open in a dialog window.

• Edit Webpart properties of your Data View Web Part
• Under Data View Properties -> Click on XSL Editor
• Copy the entire contents to a code editor like Visual Studio or Notepad++.
• Search for the string ‘a href’ – there should only be 1 string.
• Just above the line ‘<a href….”>
• Add in the following code:

<script type=”text/javascript”>

function ModalDialog(url) {

var options = {

url: url, title: “<change this to your title>”,

allowMaximize: true,

showClose: true,

width: 800,

height: 600,

dialogReturnValueCallback: silentCallback};

SP.UI.ModalDialog.showModalDialog(options);

}

function silentCallback(dialogResult, returnValue) {

}

function refreshCallback(dialogResult, returnValue) {

SP.UI.Notify.addNotification(‘Operation Successful!’);

SP.UI.ModalDialog.RefreshPage(SP.UI.DialogResult.OK);

}

</script>

• Next, modify the URL so that it looks like this:

 <a href=”javascript:ModalDialog2(‘http://sharepoint/DispForm.aspx?ID={@ows_ID}‘)“>

• Copy the XSL back to the webpart and save.

Your links should now open in a dialog window.
