    1.ListSearch Server Reference

    PromptText - Message to display when the ListBox or DropDownList is given focus. Default is 'Type to search'. The PromptText is replaced by the search text typed by the user.

    PromptCssClass - The name of the CSS class to apply to the prompt message.

    PromptPosition - Indicates whether the message should appear at the Top or Bottom of the ListBox. The default is Top.

    QueryPattern - Indicates how the typed characters should be used in the search query. The default pattern queries for results that start with the typed word.

    IsSorted - Indicates if items added to the List are expected to be sorted. The default is false. If set to true it allows the code to perform a faster search instead of having to determine the same before performing the search.

    QueryTimeout - Indicates whether the search query should be reset after the timeout if no match is found. The default is 0, meaning no auto reset behavior.

    • OnHide - The OnHide animation will be played each time the
