LoopExists Method

Checks if a loop exists in the loaded template.

Syntax

Visual Basic
C#

'Declaration
 
Public Function LoopExists( _ 
   ByVal name As String _ 
) As Boolean

public bool LoopExists( 
   string name 
)

Parameters

name: The name of loop to check for.

Return Value

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

Remarks

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

Example

Use LoopExists to avoid expensive operations

Visual Basic

'Load a template from /Files/Templates/MyFolder/MyTemplate.html
Dim t As New Template("MyFolder/MyTemplate.html")
'Set a tag value 
t.SetTag("MyTag", "Hello world!")
'Check if the loop exists in template before getting the data
If t.LoopExists("MyLoop") Then
Dim loopTemplate As Template = t.GetLoop("MyLoop")
For Each p As Content.Page In Content.Page.GetPagesByAreaID(1)
	loopTemplate.SetTag("PageName", p.MenuText)
	loopTemplate.CommitLoop()
Next
End If
