Winform Combox 下拉模糊匹配

combox 自动匹配可以设置两个属性：

cmbProdList.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
cmbProdList.AutoCompleteSource = AutoCompleteSource.ListItems;

设置后可以自动匹配，但不能模糊匹配。

下面是自己实现模糊匹配方法，实际上用到DataView 过滤功能，重新绑定数据，就这么简单。

private void cmbProdList_TextChanged(object sender, EventArgs e)

{
string keys = cmbProdList.Text.Trim();
if (keys.Length > 0)
{
UserList.RowFilter = " Title LIKE '*" + keys + "*'";
cmbProdList.DroppedDown = true;
}
cmbProdList.DataSource = UserList;
cmbProdList.DisplayMember = "Title";
cmbProdList.ValueMember = "Id";
Cursor.Current = Cursors.Default;//设置鼠标显示
//cmbProdList.Refresh();
}
