VisualTreeHelper.GetOffset Method

The returned offset value is relative to the parent of the Visual. If you want to return an offset value that is not relative to the parent of a Visual, use the TransformToAncestor method.

The following markup example shows a TextBlock that is defined with Margin value of 4.

<TextBlock Name="myTextBlock" Margin="4" Text="Hello, world" />

The following code example shows how to use the GetOffset method to retrieve the offset of the TextBlock. The offset values are contained within the returned Vector value.

// Return the offset vector for the TextBlock object.
Vector vector = VisualTreeHelper.GetOffset(myTextBlock);

// Convert the vector to a point value.
Point currentPoint = new Point(vector.X, vector.Y);

The offset takes into account the Margin value. In this case, X is 4, and Y is 4.
