SPContext.SetCachedField delegate

Implements a callback to set cached field values.

Namespace:  Microsoft.SharePoint
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

Syntax

'Declaration
Public Delegate Sub SetCachedField ( _
    fieldName As String, _
    cachedFieldValue As String _
)
'Usage
Dim instance As New SetCachedField(AddressOf HandlerMethod)

public delegate void SetCachedField(
    string fieldName,
    string cachedFieldValue
)

Parameters

• fieldName
  Type: System.String

  A string that specifies the name of the field to be cached.

• cachedFieldValue
  Type: System.String

  A string that specifies the cached field output. This parameter can contain an empty string if there is nothing to display.

Remarks

To speed up rendering of field controls on non-Display form pages, you can implement a callback that caches the values. For security reasons, this callback can be used in Display mode only, and cannot be called for certain field controls (for example, for a Lookup field to a security-trimmed list). It is best practice to avoid setting callbacks for draft versions or for pages that are checked out.
