  Hi Rahul,
  It could be something like this
  
  

   public void Execute(IPluginExecutionContext context)
          {
  
              DynamicEntity entity = (Microsoft.Crm.Sdk.DynamicEntity)context.InputParameters.Properties["Target"];
  
              // check for certain conditions 
              if (entity.Properties.Contains("fieldname"))
              {
                  entity.Properties.Remove("fieldname");
                
              }
              else
              {
                  // cancel delete operation with proper message
                  throw new InvalidPluginExecutionException("You don't have sufficient rights to delete the record! ");      
              }
          }
  
  
  

  Regards,
  Nishant Rana

  Hi try this code
  
  

  Public Sub Execute(ByVal context As Microsoft.Crm.Sdk.IPluginExecutionContext) Implements Microsoft.Crm.Sdk.IPlugin.Execute
  
  Dim source As Moniker
              Dim objCrmService As CrmSdk.CrmService
              Dim objAccount As CrmSdk.account
  
              If context.InputParameters.Contains("Target") Then
                  source = CType(context.InputParameters("Target"), Moniker)
  
                  'Initiate Object instance
                  objCrmService = New CrmSdk.CrmService
                  objAccount = New CrmSdk.account
  
                  'Call CRM Service
                  objCrmService = GetCrmSdkService(context)
  
                  'Get Account Object
                  objAccount = GetValueOfFieldFromAccount(source, objCrmService, strFilePath)
  
                  If objAccount IsNot Nothing AndAlso objAccount.new_FieldName <> FieldValue Then
                      Throw New InvalidPluginExecutionException("Error: You cannot delete" & objAccount.name )
                  End If
  
              End If
  End Sub

  
  Use PreImage on Pre Event for Delete Message

  Hi ,

  Delete Message returns a Moniker instead of Dynamic entity, so the above code:

  DynamicEntity entity = (Microsoft.Crm.Sdk.DynamicEntity)context.InputParameters.Properties["Target"];

  will throw an exception. The Moniker entity however contains the GUID for the entity, so you can use that to fetch the Dynamic entity if required.

  Cheers...
