By default, the HostInitTemplate property defines the template to be applied on the Host, when it is created. In other words, it's the initialization code of the host, which include adding columns, colors, and so on. Use the ExecuteTemplate property to returns the result of executing a template file. Use the Template property to execute a template without returning any result. Use the ExecuteTemplate property to execute code by passing instructions as a string ( template string ).

At creation time, the following code is applied to the host:

With .Host
	.BeginUpdate 
	With .Columns
		.Clear 
		.Add("Tasks").Editor.EditType = EditType
		With .Add("")
			.AllowSort = False
			.AllowSizing = False
			.FormatColumn = "1 pos ``"
			.Position = 0
			.Width = 32
			.Alignment = RightAlignment
			.Def(exCellPaddingLeft) = 2
			.Def(exCellPaddingRight) = 2
