Display of Appointment or adding milestone/reminder events

I would like to be able to use the scheduler to sow milestone events or reminder/appointment events.

A milestone event would have a day but not start or end time associated with it. It would be used to flag that something should happen or have happened on/by a particualr day.

A reminder/appointment event would have a day and a start time, but not an end time associated with it, eg a Dentist appointment at 2:00pm today or Get Report to Boss by 5:00 pm.

Both these features could be fudged by changing the display on the calendar so that it only displays 0, 1 or two dates (the event edit dialog currently requires two different times to be entered). But I cannot see how to do this. Can it be done, and if so how?

I think that both of these types of scheduler events would be useful additions for future releases.

Can the default height of a scheduler event be modified? At the moment in many instances nothing can be seen other than the start and end times of an event if the width of the scheduler component is not full screen. It would be useful to be able to increase the display height of an event so that a couple of extra lines of information could be displayed.

It would be good to have more built in support for mouse over event of a scheduler event. At the moment there is a tool tip showing the event Tilte, but it would be good to have options to automatically also display Place and Descriptions details when the mouse is over an event in the scheduler.

MultiThreading: Visual Styles

I'm not really sure what's going on here. But i need help. Using RadControls for WinForms Q2 2007. (Upgrade is not a solution).

I am using a multithreaded splash screen in my application (used this http://www.codeproject.com/KB/cs/apploadingarticle.aspx?fid=14122&df=90&mpp=25&noise=3&sort=Position&view=Quick&select=405630) I notice an unusual behavior that the multithreading causes: Somtimes buttons don't have text, and grids populate in memory but do not load the rows visually.

It is somehow caused by the multithreading, but the multithreading used is actually somewhat simple and shouldn't be causing any windows messaging issues.

Before my form loads, I create a new thread, and on it I draw my splash screen in a new message pump while my RadForm Loads. After it's loaded, I dispose my splash form and exit that thread completely. However, now during the lifetime of the application, all my RadControl's visual styles act extremely funky. It seems that they don't receive painting messages properly somehow or something. I am very frustrated, and after extensive scrutiny, cannot see anything wrong with my code.

Is this a known bug or something? Can anyone help?

Adding Nodes design time not allow adding children nodes

Hi,

I am using RAD Winforms Control Q1 2009. I have not installed the setup but using those dlls. I have added them in my toolbox and drag drop treeview control on my form.

First problem I have faced it the treeview control is not getting added on my form instead it was added as component (just like if we add timer, it not displayed on form but at the bottom like components)
I have to write manual code in .designer file and I had written like this.controls.add(this.radtreeview1);

Second thing I have faced it I was trying to add child nodes from designer. I could add root nodes but how can I add their children nodes. I could not find childnodes property in root nodes.
I have even edited .designer file and it works.

Am I missing something or I have to install the setup.

Thanks & Regards,
Divyesh Chapaneri

Subclassing RadTabStrip loses theme

Hello -

If I subclass RadTabStrip, I find that I lose the default theme. Here is the code:

                            public class Tabs : RadTabStrip         
                    {         
                    }         
                     
                    void Form1_Load(object sender, EventArgs e)         
                    {         
                        var tabs = new RadTabStrip();         
                        Controls.Add(tabs);         
                        tabs.BeginInit();         
                        tabs.Dock = DockStyle.Fill;         
                        tabs.Items.Add(new TabItem() { Text = "First" });         
                        tabs.Items.Add(new TabItem() { Text = "Second" });         
                        tabs.Items.Add(new TabItem() { Text = "Third" });         
                        tabs.EndInit();         
                    }         

The above works great & is themed with the default Telerik theme. However, if I replace "new RadTabStrip()" above with "new Tabs()", the default theme is lost. For RadElement subclasses, I was told to override ThemeEffectiveType and return the base Telerik type, which works quite nicely. However, being a Control rather than a RadElement, RadTabStrip doesn't support this virtual method. I'm guessing there is some other simple way for my subclass to not get in the way of the theme mechanism.

Thanks!

Wrong Currency Format

When setting the FormatString property of a GridViewDecimalColumn to "{0:c}", the output shows a boxlike symbol rather than the dollar sign. The FormatInfo property of the column is "Default". The current culture on the machine is en-US. If I set the FormatInfo specifically to "en-US", the column formats properly with the expected "$".

I am using version 2009.1.9.311 and the data is the supplied AdventureWorks database, SalesPerson table, SalesQuota column.

thank you,

Validating event shows old cell value

I want to validate the current cell before the user moves away. To achieve this I am using the Validating event of the GridView. However when I check the value of the current cell (radGridView1.CurrentCell.Value) it shows the cell's old value which is useless for validation. I want to get hold of the new value.

I did some experiments with ValueChanging event but it fires upon every keypress and therefore cannot be effectively used.

I simply want to validate the text of a cell before the user is allowed to move away.
