Density-Independent Pixels
Important
This documentation topic describes legacy technology. We no longer develop new functionality for the GridControl and suggest that you use the new DataGridView control instead.
The DevExpress GridControl specifies all dimensions in density-independent pixels (dp). Examples of properties accepting these units include: GridControl.RowHeight, GridColumn.MinWidth and SwipeButtonInfo.Width.
Density-independent pixels are relative units. On 160 DPI displays, one 1dp is equivalent to 1 physical pixel (px). On displays with higher DPI settings, the number of pixels in 1dp will increase proportionally, thus producing a sharper image while preserving element size and layout.
To determine the number of pixels in 1dp on a particular screen, divide the screen’s DPI by 160. The following table lists the results for a few common DPI settings.
| Display Density | 1 dp equals to |
|---|---|
| 120 dpi (ldpi) | 0.75 px |
| 160 dpi (mdpi) | 1 px |
| 240 dpi (hdpi) | 1.5 px |
| 320 dpi (xhdpi) | 2 px |
| 480 dpi (xxhdpi) | 3 px |
| 640 dpi (xxxhdpi) | 4 px |
