Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.1.dll

NuGet Package: DevExpress.Blazor

Declaration

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

Property Value

Type Default Description
Boolean true

true to display the Cancel button; otherwise, false.

Remarks

The command column displays predefined New, Edit, and Delete command buttons for data rows in display mode. In EditRow and EditCell edit modes, this column displays Save and Cancel buttons for the edited row. In the filter row, the column displays the Clear button.

Blazor Grid Command Column

Edit, Cancel, and Save buttons are unnecessary in EditCell mode. The following code snippet hides these buttons:

@inject NwindDataService NwindDataService

<DxGrid Data="GridDataSource"
        KeyFieldName="EmployeeId"
        EditModelSaving="OnEditModelSaving"
        DataItemDeleting="OnDataItemDeleting"
        EditMode="GridEditMode.EditCell">
    <Columns>
        <DxGridCommandColumn EditButtonVisible="false" 
                             CancelButtonVisible="false" 
                             SaveButtonVisible="false" />
        <DxGridDataColumn FieldName="FirstName" />
        <DxGridDataColumn FieldName="LastName" />
        <DxGridDataColumn FieldName="Title" />
        <DxGridDataColumn FieldName="HireDate" />
    </Columns>
</DxGrid>

@code {
    IEnumerable<objectGridDataSource { get; set; }
    NorthwindContext Northwind { get; set; }

    protected override async Task OnInitializedAsync() {
        Northwind = NorthwindContextFactory.CreateDbContext();
        GridDataSource = await Northwind.Employees.ToListAsync();
    }

    async Task OnEditModelSaving(GridEditModelSavingEventArgs e) {
        var editModel = (Employee)e.EditModel;
        // Assign changes from the edit model to the data item.
        if (e.IsNew)
            await Northwind.AddAsync(editModel);
        else
            e.CopyChangesToDataItem();
        // Post changes to the database.
        await Northwind.SaveChangesAsync();
        // Reload the entire Grid.
        GridDataSource = await Northwind.Employees.ToListAsync();
     }

    async Task OnDataItemDeleting(GridDataItemDeletingEventArgs e) {
         // Remove the data item from the database.
        Northwind.Remove(e.DataItem);
        await Northwind.SaveChangesAsync();
        // Reload the entire Grid.
        GridDataSource = await Northwind.Employees.ToListAsync();
    }

    public void Dispose() {
        Northwind?.Dispose();
    }
}
