How to: Customize Data Formatting in the Windows Forms DataGridView Control
The following code example demonstrates how to implement a handler for the xref:System.Windows.Forms.DataGridView.CellFormatting?displayProperty=nameWithType event that changes how cells are displayed depending on their columns and values.
Cells in the Balance column that contain negative numbers are given a red background. You can also format these cells as currency to display parentheses around negative values. For more information, see How to: Format Data in the Windows Forms DataGridView Control.
Cells in the Priority column display images in place of corresponding textual cell values. The xref:System.Windows.Forms.ConvertEventArgs.Value%2A property of the xref:System.Windows.Forms.DataGridViewCellFormattingEventArgs is used both to get the textual cell value and to set the corresponding image display value.
Example
[!code-csharpSystem.Windows.Forms.DataGridViewCustomizeDataFormatting#00] [!code-vbSystem.Windows.Forms.DataGridViewCustomizeDataFormatting#00]
Compiling the Code
This example requires:
-
References to the System, System.Drawing, and System.Windows.Forms assemblies.
-
xref:System.Drawing.Bitmap images named

For information about building this example from the command line for [!INCLUDEvbprvb] or [!INCLUDEcsprcs], see Building from the Command Line or Command-line Building With csc.exe. You can also build this example in [!INCLUDEvsprvs] by pasting the code into a new project. Also see How to: Compile and Run a Complete Windows Forms Code Example Using Visual Studio.
