RichEditControl.GetPositionFromPoint Method

Gets the position in the document closest to the specified point.

Namespace:DevExpress.XtraRichEdit
Assembly:DevExpress.XtraRichEdit.v17.2.dll

Expanded Syntax

Parameters

clientPoint
Type: PointF
A System.Drawing.PointF object that specifies a point in the RichEditControl window.

Return value

Type: DocumentPosition
A DevExpress.XtraRichEdit.API.Native.DocumentPosition object representing a position in the document.

Expanded Remarks

The GetPositionFromPoint method returns the closest document position for a specified point or null reference (Nothing in Visual Basic). The coordinate system used is a standard one, where the origin is located at the upper left corner of the RichEditControl. Use the DevExpress.Office.Utils.Units.PixelsToDocuments method to translate coordinates.

Note

If you handle the DragDrop, DragEnter, or DragOver event, an additional conversion step is required. The X and Y properties of the DragEventArgs are in screen coordinates, not client coordinates. Use the PointToClient method of the RichEditControl to convert a point with coordinates taken from the DragEventArgs to client coordinates

Expanded Example

Show Me

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=T210437.

The following code gets the mouse position and displays coordinates in a tooltip.

The RichEditControl instance is passed to the BarItem.ItemClick event handler using the BarItem.Tag property.
