Remarks

Templates are HTML or XSLT files placed in the /Files/Templates folder of a Dynamicweb installation. Templates are the rendering engine of Dynamicweb merging the markup (or XSLT) with the dynamicweb values delivered by the system.

Template language looks like normal markup with comment style variables: <h1><--@TagName--&gt;&lt;h1&gt;. Runtime the <--@TagName--&gt; is replaced by a value set with SetTag(string, string).

LoadTemplate(string)

Loads a Template file into the object from disk specified by path parameter.

public override void LoadTemplate(string path)

Parameters

path string

The path to the Template file relative to the /Files/Templates/ folder.

Remarks

Usually used with the constructor of the Template object. See the Template reference for a full example. Use Html property to load markup from a string.

LoadTemplate(string, bool)

Loads a Template file into the object from disk specified by path parameter.

public override void LoadTemplate(string path, bool forceRecompile)

Parameters

The path to the Template file relative to the /Files/Templates/ folder.

forceRecompile bool

Remarks

Usually used with the constructor of the Template object. See the Template reference for a full example. Use Html property to load markup from a string.

Examples

using System;
using Dynamicweb.Rendering;

namespace Dynamicweb.Examples.Rendering
{
	class TemplateSample
	{
		public string RenderTemplate()
		{
			//Load template from /Files/Templates/MyModuleName/List.html
			var t = new Template("MyModuleName/List.html");

			//Render string template tag <!--@WelcomeMessage-->
			t.SetTag("WelcomeMessage", "Hello world");

			//Render boolean template tag <!--@IsTuesDay-->
			t.SetTag("IsTuesday", DateTime.Now.DayOfWeek == System.DayOfWeek.Tuesday);

			//Render a datetime template tag <!--@TodaysDate--> - and also the <!--@TodaysDate.*--> date time extensions
			t.SetTag("TodaysDate", DateTime.Now);

			//Test if the loaded template contains a specific tag - if not do not do expensive work.
			if (t.TagExists("MyCalculation"))
			{
				t.SetTag("MyCalculation", "CallExpensiveMethod()");
			}

			//Test if the loop MyItems is present in the loaded template, and if not the code will not be executed.
			if (t.LoopExists("MyItems"))
			{
				//Create a loop in the template <!--@LoopStart(MyItems)--><!--@LoopEnd(MyItems)-->
				Template t2 = t.GetLoop("MyItems");
				for (var i = 1; i <= 5; i++)
				{
					//Render a counter as a template tag inside the loop <!--@MyCounter-->
					t2.SetTag("MyCounter", i);
					//Commit the loop and make ready for the next iteration
					t2.CommitLoop();
				}
			}

			//Render the template html with the parsed template tags and loops.
			return t.Output();
		}

	}
}

Remarks

Should only be called once for each instance of the template object. Use CommitLoop() inside a loop.

			{
				t.SetTag("MyCalculation", "CallExpensiveMethod()");
			}

			//Test if the loop MyItems is present in the loaded template, and if not the code will not be executed.
			if (t.LoopExists("MyItems"))
			{
				//Create a loop in the template <!--@LoopStart(MyItems)--><!--@LoopEnd(MyItems)-->
				Template t2 = t.GetLoop("MyItems");
				for (var i = 1; i <= 5; i++)
				{

SetTagValue(string, object)

Sets a tag as its object value for use in Razor templates.

public void SetTagValue(string name, object value)

Parameters

name string

The name of the tag.

value object

The value of the tag as an object.

Remarks

If the template is Razor the value will persist as an object of the passed type and can be used directly in the template. In this way it is possible to pass a full object, i.e. a 'Person', 'Product' or similar to the template engine. If the template being used is HTML or XSLT the passed value is converted to either string, integer, boolean, date, double or decimal.

SetViewModel(ViewModelBase)

Sets the view model.

public void SetViewModel(ViewModelBase viewModel)

Parameters

viewModel ViewModelBase

The view model.

SetViewParameters(IDictionary<string, object>)

public void SetViewParameters(IDictionary<string, object> parameters)

Parameters

parameters IDictionary<string, object>

TagExists(string)

Checks if a tag exists in the loaded template.

public bool TagExists(string name)

Parameters

name string

The name of tag to check for.

Returns

bool

true if the tag is found in the template; otherwise false

Remarks

Used for optimizing performance. If the value of a tag is expensive to render, there is no need to execute the code if the template is not going to use the data.
