NuGet Package: DevExpress.Web


public virtual IncrementalFilteringMode IncrementalFilteringMode { get; set; }

Property Value

Type Default Description
IncrementalFilteringMode Contains

One of the IncrementalFilteringMode enumeration values.

Available values:

Name Description

The editor filters items that contain the filter string.


The editor filters items that begin with the filter string.


The editor does not filter items.


The editor allows its items to be filtered in a drop down window by the text typed in the editor’s input box. Use the IncrementalFilteringMode property to specify the editor’s filter mode.

When callbacks are enabled (e.g., by setting the AutoCompleteBoxPropertiesBase.EnableCallbackMode property to true), the incremental filtering feature functions via callbacks to the server.


The IncrementalFilteringMode property synchronizes its value with the editor’s ASPxAutoCompleteBoxBase.IncrementalFilteringMode property.


Web Forms approach:


For a full example, see the ASPxComboBox - Cascading Combo Boxes demo.

<dx:ASPxComboBox runat="server" ID="CmbCountry" DropDownStyle="DropDownList" IncrementalFilteringMode="StartsWith"
    TextField="CountryName" ValueField="CountryName" Width="100%" DataSourceID="CountriesDataSource"
    <ClientSideEvents SelectedIndexChanged="function(s, e) { OnCountryChanged(s); }" />

MVC approach (Token Box):

@Html.DevExpress().TokenBox(settings =>
    settings.Name = "tokenBox1";

    settings.Properties.TextField = "Name";
    settings.Properties.ValueField = "Email";

    settings.Properties.IncrementalFilteringMode = IncrementalFilteringMode.StartsWith;
    settings.Properties.IncrementalFilteringDelay = 500;
