Dynamically change HeaderFormat

Hi,

I have a long HeaderFormat string for day view but when I change the ActiveView I would like to change the HeaderFormat to a shorter string such as mm/dd. I tried this in the ActiveViewChanged by doing the following without any luck.

Is it possible to do this?

Thank you.
David

private void Scheduler_ActiveViewChanged(object sender, SchedulerViewChangedEventArgs e)

{

if (e.NewView.ViewType == SchedulerViewType.Week)

Scheduler.GetWeekView().HeaderFormat = "mm/dd";

}

Hierarchical Data Binding

Hi,
I have a fairly simple object model:

public class Location

{

           public string Name { get; set; }

readonly List<Location> _locations = new List<Location>();

public List<Location> Locations

{

get { return _locations; }

}

readonly List<Printer> _printers = new List<Printer>();

public List<Printer> Printers

{

get { return _printers; }

}

public class Printer

{

public string Name { get; set; }

public string Mapping { get; set; }

public string AdditionalInfo { get; set; }

public string Guid { get; set; }

}

So a location can have any number of sub-locations, and each location can have any number of printers.

I'd like to bind this to a RadTreeView, such that the 'Name' property of the location/printer is shown

e.g
Location#1
Location#2
Location#3
Location#4
Printer#1
Printer#2
Location#5
Printer#3

etc.

The object model is loaded from xml at the moment, a sample of which can be seen here:

AllowMultipleView with dock to fill?

Hi,

We are trying to replace a previous third party calendar control with your RadCalendar. We have a calendar that is on a form that can be resized. If the form is maximized, we expect the # of months (rows) to increase. The MultiViewRows looks like a fixed value, so we really don't know how many rows to display based on the resolution of the user.

Is there a way to make this function like Outlook where changing the window size automatically adjusts the number of months to display?

Thanks,
David

Dynamically adding data with a preset xaxis range

I am trying to create a line chart that will be filled in real-time over a 2hr time period. It will be something like PerfMon in that I will start with just 1 data point and each minute I will add a new one until I reach 2hrs, at which time the first data point is removed, and from then on I show the last 2hrs of data with the line data scrolling each minute.

I have made this work by simply adding to the list the chart is data bound to. But the xaxis changes every minute to accommodate the new data point, up until 2hrs. I'd like to preset the xaxis to show 2hrs in 1min increments even though I don't have data yet. Is this possible?

I thought about prefilling the databound list with values of 0, but then the line chart looks odd because it goes to zero for all future points. How else could I accomplish this?

Problem with RadTextBox.Focused in Telerik 2010Q1

I have a piece of code that refreshes a RadTextBox Text property depending on external events. In order not to change the Text property while the user is typing in the text box I check the Focused property first and proceed in overwriting the Text property only if it is false, the relevant code looks like this:

    
            private void event_ExternalUpdate(object sender, EventArgs args) 
        
            { 
        
                if (!textBox.Focused) 
        
                    textBox.Text = "foo"; 
        
            }

However in Telerik 2010Q1 this does not seem to work. I have tried to check at runtime and apparently the Focused property is always false even though I am editing that particular text-box. I have made a super-simplified test case and tried it with both Telerik 2009Q3 and 2010Q1 and it works correctly under version 2009Q3 (Focused is set to true when I'm typing in the field) but not on 2010Q1. Is this a bug or is there another way to check if a specific control has the input focus?

As a temporary workaround I noticed that the FocusedElement property is null when the text-box doesn't have the input focus and points to the embedded RadTextBoxItem when it has focus so I'm using it instead. However because FocusedElement is not documented I am a bit wary of using it.

RichtextBox Video

Hello,

I understand the RichTextBox in conjunction with a RibbonBar can be used to create an Editor for WinForms applications. Can you direct me to any video detailing its capabilities. I want to build an integrated Editor solution within the WinForms application and want to ensure I get most of the functionality you would get with MSWord such as paragraphs, formatting, bullets, tables, headers, footers etc.

Also I believe this is only available with framework 4.0?

Thank You,

Kerry

Change a RadButton theme after application theme has been applied

I've applied a theme to the application using

ThemeResolutionService.ApplicationThemeName = "MyTheme";

All works as expected, my theme is applied.

Later on in the application, one specific RadButton needs to have a different theme applied programatically, say "MyThemeWarning"

So I try

myButton.ThemeName = "MyThemeWarning";

but nothing changes, the button remains with the theme that was applied to the application. I have verified MyThemeWarning is being loaded by the ThemeResolutionService.

What is the correct way to change the theme of a specific RadButton after the ApplicationThemeName has been set?

Add RadDropDownList to RadGridView

I'm sure I'm missing something very simple here but I want to add a RadDropDownList to a RadGridView at design time but can't find where I change the default RadGridViewTextBox column to something else. I've looked at several code examples for doing this dynamically but want to know how to do it at design time please. I also want to be able to add CheckBox columns etc. but figure once I get an answer to the first question the others will be relatively similar. My environment is WinForms.

Thanks and best regards
