   string key,
   string value
)

   ByVal key As String, _
   ByVal value As String _
)

key: String

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method must be called within the lambda passed to QueuedTask.Run.

Remarks

This method was created so developers have a way to uniquely assign a value or multiple values to an element that can not be changed in the UI and therefore provides a predictable way to find an element. Each entry has a key/value pair and you find the value using the GetCustomProperty method. You can overwrite values simply be reentering the same key with a different value. There are no methods to remove keys.

Example

//Set a custom property on an element.

//Perform on the worker thread
await QueuedTask.Run(() =>
{
  element.SetCustomProperty("MyKeyString", "MyValueString");
});

Requirements
