根据文本框中的文本类型进行筛选

我有一个文本框和一个列表框，通过以下代码绑定到数据表：

StudentTableAdapter studentTableAdapter = new StudentTableAdapter();
IMDataSet.StudentDataTable studentDataTable;
studentDataTable = studentTableAdapter.GetData();
mainGrd.DataContext = studentDataTable;

和以下 XAML：

<!-- Student Data Template-->
    <DataTemplate x:Key="StudentDataTemplate" DataType="local:IMDataSet+StudentRow" >
        <DataTemplate.Resources>
            <local:PhoneNumberConverter x:Key="phoneNumConv"/>

当用户写一个数字时，我想过滤列表框默认联系人属性。当他写一个单词时，按名称属性过滤它。我该怎么做？提前谢谢。
