Problem:

In a Visual COBOL 2010 Winform project, how does one display a Tooltip image for a dataGridView control where the image displayed is dependant on the row in the control over which the mouse is currently hovering? Each time the mouse is moved over a different row the image to display will be changed to reflect the new row.

Resolution:

This demo shows how to display a Tooltip image for a dataGridView control which is dependant on the row in the control over which the mouse is currently hovering.

Each time the mouse is moved to a different row the image to display will be changed to reflect the new row.

Please download and unzip the attachment called GridTooltip.zip into your C: drive, retaining the folder structure in the zip file.

Open Visual Studio 2010 and open the solution C:\GridTooltip\GridTooltip\GridTooltip.sln.

Build and run the demonstration by pressing the F5 key.

Hover over each row in the dataGridView control to see the Tooltip that is displayed for each.

Click the Exit button when done.

To debug the project, start it by pressing F11.
