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")); } }}

Hello,
I have a font issue only for the question mark (?) in breadcrumb. I've tried some different themes. They all have the same issue. It doesn't depend on the theme.
Please see the attached picture.
I've found a similar thread in the forum, but the solution hasn't worked for me.

Thank you by advance.
I have a gridview, I want to display in Master-Child mode. But the performance is really bad when loading data. I added BeginUpdate/EndUpdate before and after I want to load or modify some binding data. But I get the following error randomly after I modify my data several times.

Hello,
I'm desperately trying to change the color of the background of my chart (inside of the axis = plot area in Excel - see attached). I tried the background property for the area, the grid... I also tried to alternate the same color in my grid.
How should I do that?
Thanks,
Mathias

if (e.Rows [0] .Cells [1] .Value == null) { AlertOperation (new string [] {"No degree specified", "0"}); e.Cancel = true; return; }
When using the detail view, the default column width is too wide. Is it possible to set the width before the dialog is shown?
I would also prefer that the column header text be left justified.
The first image shows how it looks now and the second image shows how I want it to look.

Hello,
I'm trying to implement a (Kanban style) BoardView. It's similar to CardView (grouped cards, with drag&drop functionality), but i need a custom layout method: horizontal groups (columns), and vertical items (cards). So i was trying to inherit from ListView (like a CardView), but i cant override internal methods and properties.
I want to inherit from a theme-supported class (CardView/ListView ), not directly from radControl.
Any suggestions?
Thanks!

Hi!
Is there a way to cancel a loading because I have issues with loading certain files (big or complex one) and trying to load others files while is loading is just worst.
Thanks!
