Filtering in Blazor DropDown List component
The DropDownList has built-in support to filter data items when AllowFiltering is enabled. The filter operation starts as soon as you start typing characters in the search box.
@using Syncfusion.Blazor.Data
@using Syncfusion.Blazor.DropDowns
<SfDropDownList TValue="string" TItem="EmployeeData" Placeholder="Select a Employee" Query="@Query">
<SfDataManager Url="https://ej2services.syncfusion.com/production/web-services/api/Employees" Adaptor="Syncfusion.Blazor.Adaptors.WebApiAdaptor" CrossDomain=true></SfDataManager>
<DropDownListFieldSettings Text="FirstName" Value="EmployeeID"></DropDownListFieldSettings>
</SfDropDownList>
@code {
public Query Query = new Query();
public class EmployeeData
{
public int EmployeeID { get; set; }
public string FirstName { get; set; }
public string Designation { get; set; }
public string Country { get; set; }
}
}The output will be as follows.
Diacritics Filtering
DropDownList supports diacritics filtering which will ignore the Diacritics and makes it easier to filter the results in international characters lists when the IgnoreAccent is enabled.
In the following sample, data with diacritics are bound as dataSource for DropDownList.
@using Syncfusion.Blazor.DropDowns
<SfDropDownList TValue="string" TItem="Data" Placeholder="e.g: Aero" AllowFiltering=true IgnoreAccent=true DataSource="@Country">
<DropDownListFieldSettings Value="Name"></DropDownListFieldSettings>
</SfDropDownList>
@code {
public class Data
{
public string Name { get; set; }
}
List<Data> Country = new List<Data>
{
new Data() { Name = "Aeróbics"},
new Data() { Name = "Aeróbics en Agua"},
new Data() { Name = "Aerografía"},
new Data() { Name = "Águilas"},
new Data() { Name = "Ajedrez"},
new Data() { Name = "Ala Delta"},
new Data() { Name = "Álbumes de Música"},
new Data() { Name = "Alusivos"},
new Data() { Name = "Análisis de Escritura a Mano"},
};
}The output will be as follows.
