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")); } }}10 Answers, 1 is accepted

Actually I originally tried radTextBoxControl1.AutoCompleteDataSource = items;
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).
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.

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.

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);
}
}
I am glad that this works now. Do not hesitate to contact us if you have other questions.
