Using the TKDataFormAutoCompleteInlineEditor

TKDataFormAutoCompleteInlineEditor is a bit more advanced editor which provides an out of the box quick search functionality. This editor uses the TKAutoCompleteTextView standalone element and all its functionality like DisplayMode is available to the RadDataForm editor.

Setting the suggestions 'Source'

Because of the nature of the RadAutoCompleteTextView the editor which exposes its functionality requires some additional data to be passed to it which will be used as the 'suggestions' when a user starts typing in its textbox. Suggestions can be set through the ValuesProvider property of the TKDataFormEntityDataSourceHelper and setting it to array of strings.

The example below uses the setup from the Getting Started topic.

var dataSource = new TKDataFormEntityDataSourceHelper(new PersonalInfo());

dataSource["Account"].EditorClass = new Class(typeof(TKDataFormAutoCompleteInlineEditor));        
dataSource["Account"].ValuesProvider = NSArray.FromStrings(new string[] { "CMOK", "Drako", "Falkor", "Longma", "Pyrene" });

Setting the DisplayMode

If you are familiar with the TKAutoCompleteTextView element you know that is supports out of the box two different selected items display modes:

• Token - the selected item from the 'suggestion box' is displayed as a box with a remove 'X' button
• Plain - the selected item's text is appended and autocompleted after an item from the 'suggestion box' is selected

When using the DataFormRadAutoCompleteInlineEditor you too have the option to change the editor's DisplayMode by simply setting the AutoCompleteDisplayMode of the AutoCompleteTextView control inside the UpdateEditor method of the DataForm Delegate:

class MydDataFormDelegate : TKDataFormDelegate
{
    public override void UpdateEditor(TKDataForm dataForm, TKDataFormEditor editor, TKEntityProperty property)
    {
        if(property.Name == "Account")
        {
            (editor as TKDataFormAutoCompleteInlineEditor).AutoCompleteView.DisplayMode = TKAutoCompleteDisplayMode.Tokens;
        }   
    }  
}

Here is the result:
