Limit the minimum filter character

You can set the limit for the character count to filter the data on the AutoComplete. This can be done by set the minLength property to AutoComplete.

In the following example, the remote request does not fetch the search data, until the search key contains three characters.

    <AutoCompleteComponent id="atcelement" query={query} dataSource={searchData} sortOrder={sortOrder} filterType= "StartsWith" fields={fields} placeholder="Find a customer" minLength={3}/>
);
}
ReactDOM.render(<App />, document.getElementById('sample'));

Case sensitive filtering

Data items can be filtered either with or without case sensitivity using the DataManager. This can be done by set the ignoreCase property of AutoComplete.

The below sample depicts how to filter the data with case-sensitive.

Diacritics Filtering

An AutoComplete 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 AutoComplete.
