Getting values from other fields inside open UI

[Former Member]

Say you have a custom WPF definition for a string edit field.

Inside the C# code how would you get the value for another field or property for use in your custom control at runtime?

Riley,

Pass up that value as an Agentry Value to the control.  Agentry Values are a sub-section of the External Value tab on the screen field you are extending with OpenUI.  The Agentry Value must be set via a rule, and will be evaluated at runtime when the OpenUI control is created.  Then from your C# code on WPF, you must create an instance of the Agentry interface you are extending, then call a method to retrieve the AgentryValue that you defined and set on the screen control:

IAgentryControlViewModelStringDisplay viewModel;

viewModel = this.DataContext as IAgentryControlViewModelStringDisplay;

string str = viewModel.GetAgentryString("TEST");

The above will return the AgentryValue you set for "TEST" on the screen control.

Does it have to be the the Control View you are extending?  What if I went:

AgentryClientSDK.IAgentryControlViewModel vm = DataContext as AgentryClientSDK.IAgentryControlViewModel;

            string blob = vm.GetAgentryString("blobValue");

Even though I extend say ICustomAgentryControl

Also the Agentry value has to be set by a rule?

Riley,

Picking the IAgentryControlViewModel should probably work for you, but you will need to experiment.  Yes, the Agentry Value must be set via rule.
