AutoCompleteBoxPropertiesBase.FilterMinLength Property
Gets or sets a value that defines the minimum length for the filter string input, after which filtering operations are initiated.
Namespace: DevExpress.Web
Assembly: DevExpress.Web.v24.2.dll
Declaration
Property Value
| Type | Default | Description |
|---|---|---|
| Int32 | 0 | An integer value specifying the minimum length for the filter string input. |
Remarks
When the editor is in incremental filtering mode, it has the capability to start filtering only after an end-user has typed a specific number of symbols in the editor’s text box. The FilterMinLength property can be used to define the minimum length for the filter string input, after which filtering operations are initiated.
This behavior is extremely useful when the editor works with a large amount of data. Applying a filter each time a new symbol is typed is not sensible, due to the large size of the data set. This could affect web site performance. Instead, delaying the start of filter operations by using the FilterMinLength property allows you to provide end-users with more predictable results, and to improve the performance of your page.
Note
- The combo box does not display items until the filter string reaches the minimum length (if the FilterMinLength property value is greater than 0).
- The FilterMinLength property synchronizes its value with the editor’s ASPxAutoCompleteBoxBase.FilterMinLength property.
