By default, the checkboxsize will not be changed based on current DPI. So, checkbox will be drawn with the default size in all DPI. In order to change the CheckBox size based on the current DPI, the CheckboxSize property of GridCheckBoxCellRenderer class can be used. Code Snippet C# //To change the CheckBox size based on DPI.
GridCheckBoxCellRenderer renderer = this.gridControl1.CellRenderers["CheckBox"] as GridCheckBoxCellRenderer;
System.Drawing.Size checkboxSize = renderer.CheckBoxSize;
//Default DPI
float defaultDpi = 96;
float currentDpi;
using (Graphics g = this.CreateGraphics())
{
currentDpi = g.DpiX;
if (currentDpi != defaultDpi)
{
float scalefactor = currentDpi / defaultDpi;
renderer.CheckBoxSize = new Size((int)(scalefactor * checkboxSize.Width), (int)(scalefactor * checkboxSize.Height));
}
}
VB 'To change the CheckBox size based on DPI.
Dim renderer As GridCheckBoxCellRenderer = TryCast(Me.gridControl1.CellRenderers("CheckBox"), GridCheckBoxCellRenderer)
Dim checkboxSize As System.Drawing.Size = renderer.CheckBoxSize
'Default DPI
Dim defaultDpi As Single = 96
Dim currentDpi As Single
Using g As Graphics = Me.CreateGraphics()
currentDpi = g.DpiX
If currentDpi <> defaultDpi Then
Dim scalefactor As Single = currentDpi / defaultDpi
renderer.CheckBoxSize = New Size(CInt(Fix(scalefactor * checkboxSize.Width)), CInt(Fix(scalefactor * checkboxSize.Height)))
End If
End Using
Screenshot
Note: The CheckBoxsize can also be changed in GridGroupingControl for current DPI as the same way.
Getting the GridCheckBoxCellRenderer C# GridCheckBoxCellRenderer renderer = this.gridGroupingControl1.TableControl.CellRenderers["CheckBox"] as GridCheckBoxCellRenderer;
VB Dim renderer As GridCheckBoxCellRenderer = TryCast(Me.gridGroupingControl1.TableControl.CellRenderers("CheckBox"), GridCheckBoxCellRenderer)
