DAM for Sitecore extends Sitecore's field controls for Web Forms and Sitecore's field helper for Sitecore MVC to render the three field types in a Sitecore page. The key information for rendering most asset types is the AssetItemId and the quality. This information is stored in the field data.

Videos are a bit more complex because they use an external video player, but they are still executed the same way.

3.1 Register control tag

For Sitecore MVC:

Code Block
languagec#
@using DFS.Data.Fields

For Web Forms:

Code Block
languagexml
<%@ Register assembly="DFS" Namespace="DFS.Web.UI.WebControls" TagPrefix="dfs" %>

3.2 How to render an asset

The field render is used to render an asset as a visual output if possible. It supports some optional attributes that can be used to control which quality is outputted.

For Sitecore MVC:

Code Block
languagec#
@Html.Sitecore().Field("MyAssetMediaField")
@Html.Sitecore().Field("MyAssetMediaField", new {quality="QualityId"})

For Web Forms:

Code Block
languagexml
<dfs:Asset runat="server" Field="MyAssetMediaField" />
<dfs:Asset runat="server" Field="MyAssetMediaField" Quality="QualityId"/>

This will render any asset type. Depending on the asset of type, the appropriate HTML is rendered.

These are the parameters that can be used for the field type Asset.

NOTE: all another not known parameters will be added to the html without any validation.

Attributes

Description

Field

Is the name of the Sitecore field. Is mandatory.

quality

If this attribute is set, the default quality is changed at runtime, to the specified Quality. Qualities are given either by the Digizuite™ quality ID (an integer) or by the quality name.

Changing the Quality may change how the asset is rendered. E.g. if an asset is a PDF, and you change the Quality to the thumbnail, the PDF will be rendered as an image.

Note that some qualities might not have a rendering output. It depends on the configuration, both in Digizuite™ and in DAM for Sitecore.

Note: DAM for Sitecore can be configured to ignore this attribute, as a part of the customization of the HtmlOutput.

width, height

Resize the asset to specific width and height.

Code Block
languagec#
@Html.Sitecore().Field("MyAssetMediaField", new {quality="QualityId", width=60, height=60})


Code Block
languagexml
<dfs:Asset runat="server" Field="MyAssetMediaField" quality="QualityId" width="60" height="60"/>


keepAspectRatio

Force image resize and keep aspect ratio.

Code Block
languagec#
@Html.Sitecore().Field("MyAssetMediaField", new {quality="QualityId", keepAspectRatio=true})


Code Block
languagexml
<dfs:Asset runat="server" Field="MyAssetMediaField" quality="QualityId" keepAspectRatio="True"/>


upscaleAllowed


Code Block
languagec#
@Html.Sitecore().Field("MyAssetMediaField", new {quality="QualityId", upscaleAllowed=true})


Code Block
languagexml
<dfs:Asset runat="server" Field="MyAssetMediaField" Quality="QualityId" upscaleAllowed="True"/>


style (CssStyle)

Set the inline CSS style for the Asset element.

Code Block
languagec#
@Html.Sitecore().Field("MyAssetMediaField", new {style="color:red;"})


Code Block
languagexml
<dfs:Asset runat="server" Field="MyAssetMediaField" style="color:red;"/>


class (CssClass)

Set the HTML class for the Asset element.

Code Block
languagec#
@Html.Sitecore().Field("MyAssetMediaField", new {class="myColor"})


Code Block
languagexml
<dfs:Asset runat="server" Field="MyAssetMediaField" class="myColor"/>


The syntax to render a link of an asset.

For Sitecore MVC:

Code Block
languagec#
@Html.Sitecore().BeginField("AssetLink", Model.Item, new {haschildren=true})
@Html.Sitecore().Field("LinkTextField", Model.Item)
@Html.Sitecore().EndField()

For Web Forms:

Code Block
languagexml
<dfs:AssetLink runat="server" Field="AssetLink">
	<sc:Text ID="linkTextField" runat="server" Field="LinkText" />
</dfs:AssetLink>


There are a number of parameters that can be used.
NOTE: all another not known parameters will be added to the html without any validation.

Attributes

Description

CssStyle

Works the same ways as other ASP.NET implementations of CssStyle.

CssClass

Works the same ways as other ASP.NET implementations of CssClass.

Field

Is the name of the Sitecore field. It is mandatory.

Quality

If this attribute is set, the default or selected quality is overridden at runtime to the specified Quality. Qualities are integers from Digizuite™ quality ID (an integer).

Note: DAM for Sitecore can be configured to ignore this attribute, as a part of the customization of the HtmlOutput.

3.4 How to render a list of assets

DAM for Sitecore extends Sitecore with a field type, allowing to register multiple assets in one list. The assets in the list can be of any asset type.

To render a AssetList:

For Sitecore MVC:

Code Block
languagec#
@Html.Sitecore().Field("AssetListField")

For Web Forms:

Code Block
languagexml
<dfs:AssetList runat="server" Field="AssetList" ListClass="MyListClass" ItemClass="MyItemClass" />

This will render the assets in a list of this type:

Code Block
languagexml
<ul class="MyListClass">
	<li class="MyItemClass"> Assets will be rendered here based on Asset Type </li>
</ul>


Attributes

Description

Field

Is the name of the Sitecore field of the type AssetList.

ListClass

If set is the class name of the <ul> tag. Optional.

ItemClass

If set is the class name of each <li> tag. Optional.

Experience Editor

In order to make the assetlist editable in Experience Editor, use Sitecores EditFrame.

For Web Forms:

Code Block
languagexml
<sc:EditFrame ID="editAssetList" runat="server" Buttons="/sitecore/content/Applications/WebEdit/Edit Frame Buttons/DFSSample"></sc:EditFrame>

For Sitecore MVC:

Code Block
languagexml
@using (Html.BeginEditFrame(Model.Item.ID.ToString(), "/sitecore/content/Applications/WebEdit/Edit Frame Buttons/DFSSample")) {}

Add your button to Core under Edit Frame Buttons – /sitecore/content/Applications/WebEdit/Edit Frame Buttons/ and remember to update the field Fields - pipe-separated list of field names to be edited by the Field Editor on the button item.  

3.4.1 Iterating an Asset List

While the field render extension for the AssetList field will be useful for many general cases, there will also be a need for more specific handling of individual items. You can get the assets as a list, and iterate over each asset.

Code Block
languagec#
AssetlistField assetList = Sitecore.Context.Item.Fields["AssetList"];
if (assetList != null)
{
	foreach (var asset in assetList.Assets)
	{
		//To request the rendering html for the asset you call the RenderAsset method.
		//It returns an RenderFieldResult object
		var renderResultItem = asset.RenderAsset();


		var title = asset.AssetMetadata.Name;
		var id = asset.AssetMetadata.AssetId;
		var assetTypeIde = asset.AssetMetadata.AssetTypeId;
		var assetTypeName = asset.AssetMetadata.AssetTypeName;
		
		//Get dynamic metadata
		var someDynamicMetadata = asset.AssetMetadata["50343"];
	}
}

You can also pass an AssetListItemAtt object to RenderAsset. This will allow you to set the attributes of each AssetListItem 


Code Block
languagec#
RenderFieldResult RenderAsset(AssetListItemAttributes assetListItemAttributes)

3.5 Rendering html templates

The rendering html for each asset type is located at: Sitecore → System → Modules → Digizuite → Render Templates. In the section HTML, there are these fields:

  • Rich Text Editor Media

  • Rich Text Editor Link

  • Asset Field Type

  • Assetlink Field Type

  • Content Editor Asset

  • Url

  • DownloadUrl

Each field correspond to different context. In these fields you can use known tags (stampvalue), which will be replaced in a pipeline called DFS.GetAssetFieldValue DFS 11.0 - 6 Pipelines in DAM for Sitecore
