Dynamics CRM 2011 Online plugin - How do I retrieve the value of an option?

Saturday, June 16, 2012 8:09 AM

I'm trying to retrieve the selected option of a "Two Options" DataType in a customized form. The options appear as radio buttons and are a simple 'True' (value = 1) and 'False' (value = 0).

My plugin is set to run on update of salesorder entity, synchronously, with a Post Image named "postBookingImage". The followng code:

            tracer.Trace("Attempting to find postImage");
            if (context.PostEntityImages.Contains("postBookingUpdate"))
            {
                tracer.Trace("postBookingUpdate Image Found");
                Entity bookingImage = (Entity)context.PostEntityImages["postBookingUpdate"];
                tracer.Trace("Created bookingImage");
                //Try Catch Block - Attempting to find out if creation or a consumption booking

                try
                {
                    if (bookingImage["new_creationbooking"].Equals(0))
                    {
                        tracer.Trace("Consumption Booking");
                    }
                    if (bookingImage["new_creationbooking"].Equals(1))
                    {
                        tracer.Trace("Creation Booking");
                    }
                }
                catch (Exception e)
                {
                    tracer.Trace("uh oh.  something bad happened");
                    tracer.Trace(e.ToString());

                }
}

gives me the error message:

Created bookingImage
System.NullReferenceException: Object reference not set to an instance of an object.
   at McGheePlugins.UpdateOAPContractSold.Execute(IServiceProvider serviceProvider)
Not an OAP Creation Booking

Does anyone have any suggestions?

Much appreciated,

-Dan

gives me the exception:

Your said in the second line that image name is postBookingImage but in the code you are using postBookingUpdate.

Hello :

From the error you told, I can think of 2 issues

1.
```
Entity bookingImage = (Entity)context.PostEntityImages["postBookingUpdate"];
```
bookingImage: does not contains this attribute ["new_creationbooking"]

2. Try to get the value of the optionset as
```
if (bookingImage.Attributes["new_creationbooking"] == false) { tracer.Trace("Consumption Booking"); } if (bookingImage.Attributes["new_creationbooking"] == true) { tracer.Trace("Creation Booking"); }
```
Let me know for further help

Thanks for catching that - the correct name is postBookingUpdate (I mis-typed it in the description); the plugin seems to be correctly referencing the image.

You may have to use System.Boolean.FalseString and System.Boolean.TrueString instead of 0 and 1. It.helped me out.
