Toolbar in Blazor DataGrid Component
29 Oct 202320 minutes to read
The toolbar in the Syncfusion Blazor DataGrid component offers several general use cases to enhance data manipulation and overall experience. Actions such as adding, editing, and deleting records within the grid can be performed, providing efficient data manipulation capabilities. The toolbar also facilitates data export and import functionality, allowing you to generate downloadable files in formats like Excel, CSV, or PDF.
This service provides the necessary methods to interact with the toolbar items. The toolbar can be customized with built-in toolbar items or custom toolbar items using the Toolbar property. The Toolbar property accepts an array of strings representing the built-in toolbar items or an array of ItemModel objects for custom toolbar items.
The following example demonstrates how to enable toolbar items in the grid.
@using Syncfusion.Blazor.Grids
@using BlazorApp1.Data
<SfGrid DataSource="@Orders" Height="200" Toolbar=@ToolbarItems>
<GridColumns>
<GridColumn Field=@nameof(OrderData.OrderID) HeaderText="Order ID" Width="120"></GridColumn>
<GridColumn Field=@nameof(OrderData.CustomerID) HeaderText="Customer Name" Width="150"></GridColumn>
<GridColumn Field=@nameof(OrderData.ShipCity) HeaderText="Ship City" Width="130"></GridColumn>
<GridColumn Field=@nameof(OrderData.ShipName) HeaderText="Ship Name" Width="120"></GridColumn>
</GridColumns>
</SfGrid>
@code {
public List<string> ToolbarItems = new List<string>() { "Search", "Print" };
public List<OrderData> Orders { get; set; }
protected override void OnInitialized()
{
Orders = OrderData.GetAllRecords();
}
}public class OrderData
{
public static List<OrderData> Orders = new List<OrderData>();
public OrderData()
{
}
public OrderData(int? OrderID,string CustomerID,string ShipCity,string ShipName)
{
this.OrderID = OrderID;
this.CustomerID = CustomerID;
this.ShipCity = ShipCity;
this.ShipName = ShipName;
}
public static List<OrderData> GetAllRecords()
{
if (Orders.Count() == 0)
{
int code = 10;
for (int i = 1; i < 2; i++)
{
Orders.Add(new OrderData(10248, "VINET", "Reims", "Vins et alcools Cheval"));
Orders.Add(new OrderData(10249, "TOMSP", "Münster", "Toms Spezialitäten"));
Orders.Add(new OrderData(10250, "HANAR", "Rio de Janeiro", "Hanari Carnes"));

}
}
return Orders;

}Enable or disable toolbar items
Enabling or disabling toolbar items dynamically in Syncfusion Blazor Grid is to provide control over the availability of specific functionality based on application logic. This feature allows you to customize the toolbar based on various conditions or individuals interactions.
You can enable or disable toolbar items dynamically by using the EnableToolbarItemsAsync method. This method allows you to control the availability of specific toolbar items based on your application logic.
In the following example, the Blazor Toggle Switch Button component is added to enable and disable the toolbar items using EnableToolbarItemsAsync method. When the switch is toggled, the ValueChange event is triggered and the toolbar items are updated accordingly.
@using Syncfusion.Blazor.Grids
@using Syncfusion.Blazor.Buttons
@using BlazorApp1.Data

}Customize Toolbar buttons using CSS
Customizing Toolbar buttons in Syncfusion Blazor Grid using CSS involves modifying the appearance of built-in toolbar buttons by applying CSS styles. This provides a flexible and customizable way to enhance the visual presentation of the toolbar and create a cohesive interface.
The appearance of the built-in Toolbar buttons can be modified by applying the following CSS styles.
.e-grid .e-toolbar .e-tbar-btn .e-icons,
.e-grid .e-toolbar .e-toolbar-items .e-toolbar-item .e-tbar-btn {
background: #add8e6;
}The following example demonstrates how to change the background color of the Add, Edit, Delete, Update and Cancel toolbar buttons by applying CSS styles
