How to scroll multiple items for one mouse wheel in WinForms DataGrid (SfDataGrid)?
1 min read
By default, in SfDataGrid you can scroll only one item while doing MouseWheel. But you can scroll multiple items while doing MouseWheel by handling the MouseWheel event in SfDataGrid.TableControl. You can achieve scroll multiple items while doing MouseWheel by increase and decrease the current position of the scroll box on the scrollbar control based on the delta value.
sfDataGrid1.TableControl.MouseWheel += OnTableControl_MouseWheel;private void OnTableControl_MouseWheel(object sender, MouseEventArgs e){
if (e.Delta == 0)
return;
var smallChange = sfDataGrid1.TableControl.ScrollRows.ScrollBar.SmallChange;
if (e.Delta > 0)
sfDataGrid1.TableControl.ScrollRows.ScrollBar.Value -= (4 * smallChange);
else
sfDataGrid1.TableControl.ScrollRows.ScrollBar.Value += (4 * smallChange);
this.sfDataGrid1.TableControl.UpdateScrollBars();
this.sfDataGrid1.TableControl.Invalidate();
}
