Blazor Grid Column Virtualization

Overview of Grid Column Virtualization

Grid column virtualization is a great addition for all of you that need to deal with large number of columns in Blazor data grid and look for ways to optimize both user experience and performance.

Enable Grid Virtual Columns

To enable virtualization, set the Grid ColumnVirtualization property to true, enable horizontal scrollbar and apply settings to the Grid Width, Height and RowHeight as shown in the example below:

<TelerikGrid Data="@MyData" Width="800px" Height="400px" RowHeight="65"
             ColumnVirtualization="true" Pageable="true" PageSize="5">

Combining Grid Virtual Columns and Rows

You can easily combine Gird Virtualized Columns and Virtualized Rows together by setting the ScrollMode="GridScrollMode.Virtual" and ColumnVirtualization="true".

Check out an example of how to combine Grid Virtualized Columns and Rows in Blazor.

Grid AutoGenerated Virtualized Columns

Grid Column virtualization works well together with automatically generated columns in Blazor Grid. As the AutoGenerateColumns is a new Grid feature you can find out more about it in the section below.

Check out an example of how to enable auto generated virtualized columns in Blazor Grid.

Blazor Grid Automatically Generated Columns

Overview of Grid AutoGenerateColumns

For cases when you want to display a list of columns in a Grid that are an exact match to your data model, you can now use the new Grid parameter AutoGenerateColumns. Set it to “true” and use the super simple code snippet to generate a Blazor Grid (as shown in the example below):

<TelerikGrid Data="@GridData" AutoGenerateColumns="true"
             Pageable="true" PageSize="10">

This simplifies column definition of the Grid and automatically generates a column for each public property of its model rather than defining each column manually. If you don't need explicitly declared columns (such as a command column or frozen columns) the <GridColumns> tag is not required.

Customizations with Grid AutoGenerateColumns

The Grid columns settings can be adapted using the multiple customization attributes available that let you specify alternative column titles, specific column order, a width differing from the one generated in the <GridAutoGeneratedColumns> tag and more.

You can use data annotation attributes to set the column titles, ban or hide grid field editing, validate the data and more. Check out the sample code demonstrating the behavior of auto-generated columns using custom attributes.

Blazor Grid Nested Models

The data that you bind to the grid may have complex objects in its model, not only primitive types, and the Grid component can now show complex (nested, navigation) properties out-of-the-box as of 2.11.0.

An example on how to use complex models with navigation properties in the Grid without flattening the model can be found in the dedicated article.

Blazor Scheduler Month View

Another favorite component that was enhanced with this release is the Blazor Scheduler. Along with the existing Scheduler views – Day, MultiDay and Week, we added the Scheduler Month view.

The Month view of the Scheduler for Blazor shows the entire month to the user. To keep the month view well organized, each day slot shows up to two events. For cases when there are more than two appointments per day, an ellipsis button provides access to the detailed DayView for the specific day.

You can enable multiple views simultaneously, so that your users can easily switch to the preferred way events are visualized in the Scheduler, as shown in the example below.

<TelerikScheduler Data="@Appointments" @bind-Date="@StartDate" @bind-View="@selectedView" Height="600px">
        <SchedulerDayView StartTime="@( new DateTime(2000, 1, 1, 7, 0, 0) )"></SchedulerDayView>
