  • Command Buttons

    • 3 minutes to read

    DevExpress Blazor editors display built-in command buttons that allow users to open a drop-down, increase/decrease the value, or clear the edit box content.

    Built-in Buttons

    You can use Show***Button properties to hide these buttons.

    You can also customize default command button or add custom buttons to editors. Follow the steps below.

    1. Add the <Buttons></Buttons> tag to the editor’s markup to define the Buttons collection.
    2. Fill the Buttons collection. This collection renders specified buttons in the order they appear in the markup.

      The following buttons are available:

      The following button is available for the DxComboBox<TData, TValue>, DxDateEdit<T>, DxDateRangePicker<T>, DxDropDownBox, DxMaskedInput<T>, DxSpinEdit<T>, DxTextBox, and DxTimeEdit<T> components:

    3. Set up button properties to customize the buttons:

      • CssClass
      • Position
      • and so on

    Buttons are displayed in an editor in the following order:

    • The “Clear” button
    • Custom buttons and customized default buttons (in the same order as they appear in markup)
    • Built-in buttons

                <DxSpinButtons />
                <DxEditorButton IconCssClass="@($"editor-icon {CurrencyButtonIconClass}")"
                                Tooltip="Change currency"

            </Buttons>
            <ChildContent>
                <DxNumericMaskProperties Culture="MaskCultureInfo" />
            </ChildContent>
    </DxSpinEdit>
    
    @code{
        double Price { get; set; }
        string CurrencyButtonIconClass { get; set; } = "editor-icon-euro";
        CultureInfo MaskCultureInfo { get; set; } = CultureInfoItems[0];
        static CultureInfo[] CultureInfoItems { get; set; } = {
                CultureInfo.GetCultureInfo("en-US"),
                CultureInfo.GetCultureInfo("de-DE")
        };
        void OnChangeCultureInfoButtonClick() {
            var isCurrentCultureUs = MaskCultureInfo.Equals(CultureInfoItems[0]);
            MaskCultureInfo = isCurrentCultureUs ? CultureInfoItems[1] : CultureInfoItems[0];
            CurrencyButtonIconClass = isCurrentCultureUs ? "editor-icon-dollar" : "editor-icon-euro";
        }
    }
    
    <style>
        .dx-demo-editor-width {
