Implements a callback to set cached field values.
Namespace: Microsoft.SharePoint
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
Syntax
Public Delegate Sub SetCachedField ( _
fieldName As String, _
cachedFieldValue As String _
)
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.
