DataGrid LoadData

The LoadData event allows you to perform custom paging, sorting and filtering.

In this demo the Job Title column uses a multi-select dropdown filter with FilterTemplate, and a Reset button clears all grid state including filters, sorts, and paging to return to the initial view.

Perform custom data-binding

1. Set the Data and Count properties.

<RadzenDataGrid Count="@count" Data="@employees"

2. Handle the LoadData event and update the Data and Count backing fields (employees and count in this case).


void LoadData(LoadDataArgs args)
{
    var query = dbContext.Employees.AsQueryable();

    if (!string.IsNullOrEmpty(args.Filter))
    {
        query = query.Where(grid.ColumnsCollection);
    }

    if (!string.IsNullOrEmpty(args.OrderBy))
    {
        query = query.OrderBy(args.OrderBy);
    }

    count = query.Count();

    employees = query.Skip(args.Skip.Value).Take(args.Top.Value).ToList();


}
