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|
