FilePath, Registry, and Custom Data Source Support

AutoComplete can be used with different kinds of Data Source like FilePath, Registry & CustomSource. The Data
Source of the AutoComplete control can be set using the Source property.

When the value of the Source property is set as FilePath, the AutoComplete will displays the path in the local
system as the source. This is illustrated in the following image.

<syncfusion:AutoComplete x:Name="AutoComplete1" Source="FilePath"/>
<syncfusion:AutoComplete x:Name="AutoComplete2" Source ="Registry"/>
<syncfusion:AutoComplete x:Name="AutoComplete3" Source="Custom">     
<syncfusion:AutoComplete.CustomSource>             
<local:CustomerListCollection/>     
</syncfusion:AutoComplete.CustomSource>
</syncfusion:AutoComplete>
AutoComplete autoComplete1 = new AutoComplete();
this.autoComplete1.Source = SourceMode.FilePath;

AutoComplete autoComplete2 = new AutoComplete();
this.autoComplete2.SelectionMode = SourceMode.Registry;

AutoComplete autoComplete3 = new AutoComplete();
this.autoComplete3.SelectionMode = SourceMode.Custom;

List<String> products = new List<String>();
customSource.Add("Diagram");
customSource.Add("Gauge");
customSource.Add("Chart");
customSource.Add("Schedule");
customSource.Add("Grid");
customSource.Add("DocIo");
customSource.Add("XlsIo");
