ISpinEditSettings.AllowMouseWheel Property

Specifies whether a user can rotate the mouse wheel to change the spin editor’s value.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(true)]
[Parameter]
bool AllowMouseWheel { get; set; }

Property Value

Type	Default	Description
Boolean	true	true if the spin editor’s value changes when a user rotates the mouse wheel; otherwise, false.

Remarks

Users can rotate the mouse wheel to change the spin editor’s value. Set the AllowMouseWheel property to false to disable this feature at runtime. To specify this value in markup, use the DxSpinEditSettings.AllowMouseWheel property.

Use the Increment property to adjust the change step value.

The ISpinEditSettings interface allows you to get and customize settings of a spin editor at runtime. You can get editor settings in the following ways:

• Call the GetColumnEditSettings method to get editor settings of the column bound to the specified data source field.

  Important

  You need to enclose your code between BeginUpdate and EndUpdate method calls to change values of Grid component parameters outside the Grid component markup. Otherwise, an exception occurs.

  var spinEditSettings = e.Grid.GetColumnEditSettings<ISpinEditSettings>("UnitPrice");
  if(spinEditSettings != null) {
      e.Grid.BeginUpdate();
      spinEditSettings.AllowMouseWheel = false;
      e.Grid.EndUpdate();
  }
  

• Handle the CustomizeFilterRowEditor event to customize a cell editor in the filter row.

  void Grid_CustomizeFilterRowEditor(GridCustomizeFilterRowEditorEventArgs e) {
      if(e.EditSettings is ISpinEditSettings spinEditSettings)
          spinEditSettings.AllowMouseWheel = false;
  }
  

• Handle the CustomizeDataRowEditor event to customize a cell editor in a data row.

  void Grid_CustomizeDataRowEditor(GridCustomizeDataRowEditorEventArgs e) {
      if(e.EditSettings is ISpinEditSettings spinEditSettings)
          spinEditSettings.AllowMouseWheel = false;
  }
