RadChart not calculatin y axis heights and values correctly

The RadChart will not calculate y axis heights and values correctly if

1. IsLogerithmic is true

2. Values exist in the x axis that are 0.

I have included a sample project that shows this problem. It was download from a Telerik forum where they said that it works. I modified it and proved that it does not. Actually, it turns out I could not attach the zip file to this message, as the attachment process only allows graphics files. I can make this project available if needed, if someone will let me know how!

The steps to reproduce are:

Run the application.
Notice that the even though I've limited the data points to a max of 10, the y axis is showing 1000000000.
Uncheck the checkbox that says "Include Zero in chart" (this will regenerate the data with no zeros.)
The chart is calculated correctly.
Check the checkbox again and switch the "Is Logerithmic" off then on again. (Notice that the the Y axis is miscalculating).
Resize the window (Here you will notice that the 1000000000 is back.

Clustered Data Source

Hi,

I'm currently exploring the use of the Clustered Data Source to improve performance when displaying a large number of map items.

Can the Clustered Data Source be setup so that it is only active for certain zoom levels?

The scenario is displaying a very large number of map items, when you are zoomed out, a number of points overlap and rather then having these all displayed, the Clustered Data Source would be used. However when zoomed in to Zoom Level 15 >, we would want all the map items displayed without any Clustered Data Source.

Many Thanks,

Adnan

Set public property with custom FieldSelectorTemplate

I have a public property on one of my classes that is configurable by a PropertyGrid. It is a string property, but I want the user to be able to set it from a RadComboBox with values provided from an OpenAccess data model. I can't seem to put all the pieces together. The closest I got puts an odd value in the public property ("Telerik.Windows.Controls.RadComboBoxItem: City, State"). I've been banging my head against this for days and I'm tantalizingly close, but I'm just not seeing something.

How do I connect all the bits? The choices to the data source and the selected item to the public property? Here's my code without all my failed efforts taking up space.

Here's the property:

private string weatherloc;

[Category("MissionBoard")]

[Description("Weather station location")]

public string WeatherLoc

{

get { return weatherloc; }

private set { weatherloc = value; }

}

Here's the RadComboBox in the DataTemplate:

<Grid.Resources>

<c:FieldTemplateSelector x:Key="DataTemplateSelector">

<c:FieldTemplateSelector.WeatherDataTemplate>

<DataTemplate>

<telerik:RadComboBox x:Name="WeatherComboBox"

Loaded="WeatherComboBox_Loaded" />

</DataTemplate>

</c:FieldTemplateSelector.WeatherDataTemplate>

</c:FieldTemplateSelector>

</Grid.Resources>

And here's the code-behind to (hopefully) populate the control:

private void WeatherComboBox_Loaded(object sender, RoutedEventArgs e)

{

using (EntitiesModel dbContext = new EntitiesModel())

{

try

{

var q = (from i in dbContext.WeatherFeeds

orderby i.Location

select new { i.Location }).ToList();

// How to bind all the bits? The public property to the SelectedItem

                // and the choices to the data source.

}

catch (SqlException sx)

{

Console.WriteLine(sx.ToString());

}

catch (Exception ex)

{

Console.WriteLine(ex.ToString());

}

Change the appointment display style

Hi,

i was wondering if i can change the display style of an appointment in radscheduleview like shown in the attached screenshot? Is it
possible?
The default appointment style does only display the subject of an appointment in the week view for example. In my opinion, this is a waste of useful display space and my goal is to display additional information like the location, resources or category of an appointment.
I looked through the examples and API documentation but didn't found any hint or solution for this problem.

thanks in advance,

best regards

Matthias

Good examples of dragging from gridview to treeview?

Hi telerik,

In my app I need to drag a row from at gridview onto a treeview.

When trying to drag, the cursor never changes to dragging-cursor. I'm a bit at a loss here.

I've tried to look at the example from "GridView Reorder Rows", but merging it over in my code has not produced the dragging cursor.

Can you confirm for me that it should be possible to drag from gridview to treeview?
Is it possible to construct a super simple example where it's done?

Internally in the treeview, I've got dragging working just fine -- the problem seems to be in allowing the dragging action to be initiated from gridview.

I'm still running Q1-release.

Thanks,

Anders, Denmark
