Text Control with Rich Formatting

I am looking for advice regarding how best to implement a text editing control that allows character-level formatting, i.e. the user can select portions of the text and format it separately from the rest. One additional point is that I am building an outliner, and would like every individual topic to be a separate control, or addressable part of the control, since each topic and the notes below it is stored separately in a database.

I am building WinForms apps using Telerik as my main UI add-on control collection.

Thanks, Stephen

Problem with RadDropDownListEditor when RadDropDownStyle.DropDown and AutoCompleteMode.SuggestAppend

Hi

I created this example to show problem that occurs in my real application.

This is my source code:

public class MyClass

{

public string MyProperty { get; set; }

}

public partial class Form1 : Form

{

private List<MyClass> _myList = new List<MyClass>();

public Form1()

{

InitializeComponent();

radGridView1.DataSource = _myList;

radGridView1.Columns[0].Width = 200;

}

private void radGridView1_EditorRequired(object sender, Telerik.WinControls.UI.EditorRequiredEventArgs e)

{

RadDropDownListEditor editor = new RadDropDownListEditor();

RadDropDownListEditorElement editorElement = editor.EditorElement as RadDropDownListEditorElement;

editorElement.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDown;

editorElement.AutoCompleteMode = AutoCompleteMode.SuggestAppend;

e.Editor = editor;

e.EditorType = typeof(RadDropDownListEditor);

}

When I want add new row I type something in cell and I press ENTER but new row is not added. Cell is cleared.

If I don`t use custom editor (comment out code in EditorRequired handler) on ENTER pressed new row is added with typed value.

How to solve this issue when I use custom editor?

Regards

RadCalendar control Navigation Step like FastNavigationStep?

I have what I hope will be a simple question to answer.

We use a RadCalendar control that we display in MultiView Mode with MultiViewColumns set to 3 (i.e. 3 months displayed) and MultiViewRows set to 1 (i.e. the display is only 1 month in height).

I have set the FastNavigationStep value to 1, which moves the calendar 3 months at a time when a Fast Navigation control is clicked (">>" or "<<). The trouble I have is that our business users would like the normal navigation controls to only move a single month at a time despite the fact that we are displaying 3 months in the calendar. For example if the months of Jan., Feb. and Mar. are displayed and the normal navigation forward control is clicked (">"), they would like to display Feb., Mar. and Apr.

The normal navigation controls (">" or "<") seem to do the same thing as the FastNavigation controls with the FastNavigationStep value set to 1. There does not seem to be a "NormalNavigationStep" property that can be set. Does anyone have a suggestion for handling something like this?

Thanks,

Bill

Updating bindinglist from seperate thread

When I have a gridview bound to a bindinglist and I update the data that the list is bound to in a seperate thread (than the GUI thread) I am getting crossthreading errors in the assignment statement. I am attempting to get around the problem by alerting the main thread to update the value. Is this the way that the gridview binding is intended to operate or have I left something out?

Column chooser event

Hi,
Is there an event that I can use to capture columns being hidden or being added from the column chooser. The reason I want this is, I have a view definition attached to the master view and some of the cell values are bitmaps. After hiding or choosing, the grid rendering goes haywire. It happened with while changing groups or applying filter, but sorted itself out by rebinding the viewdefinition on the GroupsChanged and FilterChanged events.

Thanks
Deepak

ComboBox and ListBox obsolete as of Q2 2010. Replaced by RadDropDownList and RadListControl

RadListBox and RadComboBox controls have been replaced by two brand new controls as of Q2 2010: RadListControl and RadDropDownList. The new controls provide the extensibility options that were currently lacking in the old controls, and offer much better performance, due to the use of virtualization and a new generic data engine, developed for RadGridView.

The Benefits of the new controls

RadDropDownList replaces RadComboBox and will soon offer extended and new auto complete options.

RadListControl replaces RadListBox and offers full virtualization support. It performs far better than both RadListBox and the standard ListBox control when bound to more than 1000 items. Read more in this blog post: Blazing-fast list control. Meet RadListControl for WinForms.

Both controls are easier to use and customize, and will provide better grounds for developing new features faster.

What will happen to the old controls?

The old controls will be supported for at least one year after the release of Q2 2010. Users will nevertheless be encouraged to use the new controls since they address the fundamental shortcomings of the previous controls.

Is upgrading to the new controls easy?

Upgrading from the old to the new controls should be easy and painless, unless you have extended the previous controls with custom functionality. If this is the case, please contact Telerik support and we will help you move to the new versions. We will also provide an automatic upgrade tool with Q2 2010 SP1.

Videos and instructions on how to upgrade from the old versions to the new ones will be posted shortly.

How do I get support for the new controls?

To get technical support, either contact Telerik support or post in the DropDownList and ListControl Forum.

Localization conditional formatting

Hello telerik team,
I am currenty testing your platform (RadControls for win forms versino 2009.2.9.701) in order to decide whether to use your controls at our company. I have question regarding localization of datagridview. I am using RadGridLocalizationProvider to provide localized strings and I can't find RadGridStringId enumeration values for following strings:

conditional formatting > group box "rule aplies on"
conditional formatting > strings in combo box type > for example is not equal to [Value1]
conditional formatting > format property list box > for example "RowForeColor"
