Parameters

• existingTransaction

  The existing transaction.

• newTransaction
  Type: Microsoft.VisualStudio.Text.Operations.ITextUndoTransaction
  The new transaction.

Remarks

This method merges newTransaction with existingTransaction by adding, removing, or modifying the undo primitives in the existing transaction's ITextUndoPrimitive collection. A simple implementation might add each undo primitive in the new transaction to those of the existing transaction.
