Overview
DataRequestUpdate is used by Data Abstract to update data on the server without requiring an _Intf file to invoke it. This class makes use of the RemObjects SDK's Dynamic Request support.
Location
- Assembly: RemObjects.DataAbstract.dll
- Namespace: RemObjects.DataAbstract
- Ancestry: System.ComponentModel.Component | DynamicRequest | RemoteDataAdapterRequest | DataUpdateRequest
Properties
| IncomingDeltaParameter |
|---|
|
The Name of the parameter in which the resulting delta will be returned from the server. This must be a Binary parameter.
|
| MethodName (declared in DynamicRequest) |
|
Specifies the name of the method to call. Note: If the RemoteService property is assigned and the server is available at design time, you can select the method name from a list of available methods in the Property Browser's drop down box. When doing this, the Parameters collection will automatically be populated.
|
| OutgoingDeltaParameter |
|
The Name of the parameter in which the delta will be passed to the remote server. This must be a Binary parameter.
|
| Owner (declared in RemoteDataAdapterRequest) |
|
|
| Parameters (declared in DynamicRequest) |
|
Defines the parameters that get passed into and out of the method call. For your call to succeed, these exactly have to match the parameters defined for your method; you can use the UpdateParamsFromRodl and UpdateParamsFromRodlOperation methods to populate the parameters automatically. Once the parameters are defined, you can set their values using ParameterByName("Name").Value before you make your call. Note: If the RemoteService property is assigned and the server is available at design time, you can select the method name from a list of available methods in the Property Browser's drop down box. When doing this, the Parameters collection will automatically be populated.
|
| RemoteService (declared in DynamicRequest) |
|
References the RemoteService component that defines the service to call.

Instance Methods
| constructor () (declared in DynamicRequest) |
|---|
|
|
| constructor (BaseDataAdapter) |
|
Default constructor for DataUpdateRequest.
|
| constructor (IContainer) (declared in DynamicRequest) |
|
|
| constructor (String, RemoteService) (declared in DynamicRequest) |
|
|
| constructor (String, RemoteService, array of DynamicRequestParameter) (declared in DynamicRequest) |
|
|
| constructor (String, RemoteService, DynamicRequestParameterCollection) (declared in DynamicRequest) |
|
|
| constructor (String, RemoteService, IList<DynamicRequestParameter>) (declared in DynamicRequest) |
|
|
| BeginMakeRequest (declared in DynamicRequest) |
|
|
| EndMakeRequest (declared in DynamicRequest) |
|
|
| MakeRequest (declared in DynamicRequest) |
|
Performs the actual request to the remote service.
|
| ParameterByName (declared in DynamicRequest) |
|
Returns the DynamicRequestParameter of a given name. You can use this method to conveniently populate all parameters with their proper values without relying on their ordering, as shown in the example below.
|
| ReadParameter protected (declared in DynamicRequest) |
|
|
| SetupDefaultRequest |
|
Sets or resets all parameters to the default settings needed when talking to a standard Data Abstract server implementing the IDataAbstractService interface. Note: This method is called automatically when this class is initialized. Unless you are using Dynamic Method Binding or manually modifying the request's Parameters, the request will default correctly for IDataAbstractService.
|
| UpdateParamsFromRodl (declared in DynamicRequest) |
|
Retrieves the RODL file from the server, locates the service and method and populates the Parameters collection with the appropriate parameters needed for the method call. Any parameters or values defined prior to calling UpdateParamsFromRodl will be lost.
|
| UpdateParamsFromRodlOperation |
|
|
| Validate |
|
|
| WriteParameter protected (declared in DynamicRequest) |
|
