Hiding tabs (children with no data) in ORM hierarchy

I have a grid linked to sparse object data, and would like to hide any areas that don't have data from the user. In other words, I'm linked to objects that have child collections, and would like to hide the tabs for the rows that don't have any child data. I used the advice here to hide the expander when it's not needed, but all child tabs are still shown even if only one of them has child data. Is there a way to hide tabs that don't have child data?

Only dock control once

How can I ensure that a UserControl that has been docked to an MDIForm doesn't get docked a 2nd time? That is, I need a control to only be visible once. I tried making it a singleton class, but calling the DockControl of the RadDock still added a new visual element, though one was an empty shell.

I tried to find a list of controls or some other addressable way but failed.

Thanks,

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
