I've trying to get autocomplete working. After failing in my main project I created a test project with a single radtextboxcontrol and the following code from the docs, and I'm not getting any word suggestions.

I'd prefer to have something like

var items = new List{ "Matthew", "Mark", "Luke", "John"}

radTextBoxControl1.AutoCompleteItems.AddRange(items);

but that didn't work either.

Thanks.

 

namespace TelerikWinFormsApp1
{
    public partial class RadForm1 : Telerik.WinControls.UI.RadForm
    {
        public RadForm1()
        {
            InitializeComponent();
 
            AddAutoCompleteItems();
        }
        private void AddAutoCompleteItems()
        {
            this.radTextBoxControl1.AutoCompleteMode = AutoCompleteMode.Suggest;
            RadListDataItemCollection autoCompleteItems = this.radTextBoxControl1.AutoCompleteItems;
 
            autoCompleteItems.Add(new RadListDataItem("Luke"));
            autoCompleteItems.Add(new RadListDataItem("Max"));
            autoCompleteItems.Add(new RadListDataItem("Adam"));
            autoCompleteItems.Add(new RadListDataItem("Henry"));
            autoCompleteItems.Add(new RadListDataItem("Jack"));
            autoCompleteItems.Add(new RadListDataItem("Ben"));
            autoCompleteItems.Add(new RadListDataItem("Tyler"));
            autoCompleteItems.Add(new RadListDataItem("Ethan"));
            autoCompleteItems.Add(new RadListDataItem("David"));
            autoCompleteItems.Add(new RadListDataItem("Mike"));
        }
    }
}

Actually I originally tried radTextBoxControl1.AutoCompleteDataSource = items;

Hello Tino,

Actually, this code works on my side. I have attached a small video that shows this. Could you please check this again and let me know if it is still not working.

I am looking forward to your reply.

After some experimenting it seems autocomplete doesn't work with Multiline=true on the textbox, which I need.

I have a split container with 3 panels, each with a RadTextBoxControl docked to Fill. Autocomplete works until I turn on multiline. Any workaround for this?

 

(Also I figured out the reason the code worked for you and not me is because I had the edit box docked to Fill my entire form, and I guess there was nowhere for the Suggest box to drop down).

Hello Tino,

I was able to reproduce this. Currently, a multiline scenario is not supported. I have logged this case on our Feedback Portal. You can track its progress, subscribe to status changes and add your comment to it here. I have also updated your 
Telerik Points.

Should you have any other questions do not hesitate to ask.

Greetings, already loaded the data for autocomplete, what event does it take to show the final text selected in autocomplete?

Hello Danny,

I am not sure what you want to achieve. Could you please elaborate?

In general you can access the underlying list element like this:
public RadForm1()
{
    InitializeComponent();
     
 
    this.radTextBoxControl1.ListElement.SelectedIndexChanged += ListElement_SelectedIndexChanged;
}
 
private void ListElement_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)
{
    Console.WriteLine(radTextBoxControl1.ListElement.SelectedIndex);
}

I am looking forward to your reply.

Perfect works, but it also activates when any letter is pressed and shows me zero index and I have not selected anything yet, when it is not selected it varies between 0 and -1 (vb.net)

Hi Danny,

The event arguments cointan the position which allows you to avoid the case where the list is reset: 
private void ListElement_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)
{
    if (e.Position < 0)
    {
        Console.WriteLine(radTextBoxControl1.ListElement.SelectedIndex);
    }
}

Another approach would be to use the PopupClosed event:
public RadForm1()
{
    InitializeComponent();
 
    this.radTextBoxControl1.TextBoxElement.AutoCompleteDropDown.PopupClosed += AutoCompleteDropDown_PopupClosed;
 
}
 
private void AutoCompleteDropDown_PopupClosed(object sender, RadPopupClosedEventArgs args)
{
     
}

Please let me know if there is something else I can help you with.

uniting the two parts is better, thank you very much for the help.

private void AutoCompleteDropDown_PopupClosed(object sender, RadPopupClosedEventArgs args)
{
    if (radTextBoxControl1.ListElement.SelectedIndex > 0)
    {
        Console.WriteLine(radTextBoxControl1.ListElement.SelectedIndex);
    }
}
