Sharepoint Visual studio workflow

Question

I am new to developing apps in Visual Studio for SP. I have a problem to use the standard functions for creating a workflow. Currently I need the workflow action Set field in current item, but I don't know where to find this action. Which action in VS is the replacement for that action? I was trying to use the Update list item action too, but it asks me for a C# expression, how to write the placeholders for the columns?

Answer 1

Yes you can use the UpdateListItem activity.

In the ListItemPropertiesDynamicValue property you need to set the Path and the Value. In Path select the field you want to update. In Value enter the value you want the field to be.

So, for example, if you want a field called Status - which is a Single Line of Text field - to be set to "In Progress" it would look something like this:

If the field you want to update was a Number field, then you would simply enter a number in Value.

But remember in the Value field you can also enter the name of a workflow variable, if you've defined any.

Update:

It seems you're asking how to assign a workflow variable to the workflow item's ID.

First you need the item ID. Use the GetCurrentItemId activity:

In this activity's properties set the Result property to a workflow variable of your choice, I've created one called itemId:

Then you need the Assign activity:

And set its properties like so:

WorkflowID will be assigned to the value of itemId.
