Attachment file handle with SDK

0

Hi Maximilian,

I'm not sure whether I understand your question correctly.
In your choice field you select the attachment you want to process and you are currently struggling a bit to get the correct attachment?
If this is the case I would do the following:
User the ID of the attachment as the ID of the choice field and select the attachment based on the choice field value.
var attachment = args.Context.CurrentDocument.Attachments.FirstOrDefault(x=>x.ID = 123)

If this is not the case you could look at the signing repositories. Here's a line where the attachments of the current document are processesd.
https://github.com/WEBCON-BPS/BPSExt-Signing-DocuSign/blob/5784cf2a66e946bf8a093c3f386b0b27cb0566d6/WebCon.BpsExt.Signing.DocuSign/CustomActions/Helpers/DataHelper.cs#L56

Hi Daniel,

thank you very much for your answer.
I uploaded my example in the attachment.
Yes I read in the file about the attachment, then I have choice field where I choose the file.
Then I trigger my action and give everything into the C#-code.
In the C#-code I want to work with the ID of the selected file.

Your code snippet:
var attachment = args.Context.CurrentDocument.Attachments.FirstOrDefault(x=>x.ID = 123)
was read only property with the ID.

I hope that this declaration can help you a little bit more.
Thank you very much and best regards

Hi Maximilian,

yes it was a simple snippet. A more elaborate one would be:
SQL Query of the choice field:
SELECT [ATT_ID] as Id, ATT_Name as Label
FROM [dbo].[WFDataAttachmets]
where ATT_WFDID = {WFD_ID}
and [ATT_IsDeleted] = 0
and [ATT_FileType] = '.xlsx'

Code:
var idOfchoiceField = GetFromConfiguration
var choiceFieldValueId = args.Context.CurrentDocument.ChooseFields.FirstOrDefault(x=>x.ID == idOfchoiceField ).Value.ID
var attachment = args.Context.CurrentDocument.Attachments.FirstOrDefault(x=>x.ID == choiceFieldValueId)

Of course, there could be an issue, when the attachment hasn't been saved before. You could add the attachment in step 1 and select the field value in step 2 after which follows you action. But this is only a guess.

Best regards,
Daniel

Good Morning Daniel,

thank you very much for your help.
I tried to rebuild it, but I get an error message in my code.
I set up an new ConfigEditableDropDownList in my code, but I don't know if this is the right thing for it.
Maybe you could look at this again.

Thank you very much and best regards
Maximilian

Hi Maximilian,

sorry, I didn't look for any syntax error when writing it here. I didn't test or even build it. Of course the error is correct, it should be a comparison so it should be == and not only =

Best regards,
Daniel

Deleted double post.

Hey Daniel,

thank you for your reply.
I got no time to test it yesterday but today I tried it with your code.
In C# I took an ConfigEditableDropDownList but when I want to configure the SDK in Webcon I always get a error message. The photo is in the attachment.
And with your way I think there must be a parse to an integer, is this right?

Thank you very much and have a good evening
Maximilian

When I look your code you were almost there.
args.Context.CurrentDocument.GetFieldValue(Configuration.ChoiceFormFieldID) already returns an PickerField object. You can either cast the returned object to a PickerField or get the pickerfield value via the PickerFields-Property
args.Context.CurrentDocument.PickerFields.GetByID(Configuration.ChoiceFormField).ID
The ID should be your attachment id.

Hi Maximilian,

I'm almost ready to start my blog but I'm not quite there yet. So there may be changes. :)
Anyway, I created a Custom Action for reading an xml file and populating an item list with the data. You will find a link to the source code at the end.

Hello Daniel,

thank you for the link. The code snippet helped me a lot for my problem. The blog is a super cool idea I hope that you will publish some more articles in future.

Thank you again and have a good day
Maximilian
