[Solved] Disable resizing column while editing cell

Hi!

I wish to disable column resizing (for example, DataGridViewColumn) while editing cell in standard manner. When I type too long text in cell then column width is growing up that is unnecessary for me. I tried to set column width in design time to "Auto" or to particular width - no effect at all. Can anybody help me?

How Can I Grouping by tags a RadGridView

I have this class

public class myObject

{

public String Name { get; set; }

public List<String> Tags{get;set;}

}

this ViewModel

public class ViewModelMainWindow:ViewModel

{

System.ComponentModel.ICollectionView m_myListOfObject;

public ICollectionView MyListOfObject

{

get { return m_myListOfObject; }

set { m_myListOfObject = value; }

}

I initialize my App

public partial class App : Application

{

MainWindow m_ViewMainWindow;

ViewModelMainWindow m_ViewModelMainWindows;

List<myObject> m_myListOfObject;

protected override void OnStartup(StartupEventArgs e)

{

Init();

m_ViewMainWindow.Show();

}

void Init()

{

m_ViewMainWindow = new MainWindow();

m_ViewModelMainWindows = new ViewModelMainWindow();

PropertyGroupDescription groupDescriptionPorte = new PropertyGroupDescription("Tags");

m_myListOfObject = new List<myObject>();

m_myListOfObject.Add(new myObject());

m_myListOfObject.Last().Name = "Element 1";

m_myListOfObject.Last().Tags = new List<string>();

m_myListOfObject.Last().Tags.Add("Tag 1");

m_myListOfObject.Last().Tags.Add("Tag 2");

m_myListOfObject.Add(new myObject());

m_myListOfObject.Last().Name = "Element 2";

m_myListOfObject.Last().Tags = new List<string>();

m_myListOfObject.Last().Tags.Add("Tag 1");

m_myListOfObject.Last().Tags.Add("Tag 3");

m_myListOfObject.Add(new myObject());

m_myListOfObject.Last().Name = "Element 3";

m_myListOfObject.Last().Tags = new List<string>();

m_myListOfObject.Last().Tags.Add("Tag 2");

m_myListOfObject.Last().Tags.Add("Tag 4");

m_ViewModelMainWindows.MyListOfObject = CollectionViewSource.GetDefaultView(m_myListOfObject);

m_ViewModelMainWindows.MyListOfObject.GroupDescriptions.Add(groupDescriptionPorte);

m_ViewMainWindow.DataContext = m_ViewModelMainWindows;

}

How can I view the groups by tags "Tag 1", "Tag 2", "Tag 3", "Tag 4" in a RadGridView?
In m_ViewModelMainWindows.MyListOfObject I have 4 groups, but in RadGridView of MainWindow I have 3 groups of list.

The MainWindow.xaml is

<Window

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" x:Class="grouping_by_tags.MainWindow"

Title="MainWindow" Height="350" Width="525">

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="137*"/>

<RowDefinition Height="183*"/>

</Grid.RowDefinitions>

<telerik:RadGridView HorizontalAlignment="Left" Height="320" VerticalAlignment="Top" Width="517" ItemsSource="{Binding MyListOfObject}" Grid.RowSpan="2"/>

</Grid>

</Window>

Best regards

Riccardo

[Solved] PlotArea - Margin not equivalent

Hi,

I got some axis on the left and right side and it turns out the left margin of the plot area is a few pixels thick when the right margin is not.
Left side: https://dl.dropboxusercontent.com/u/55589036/Pictures/Screenshots/20150210105316.png
Right side: https://dl.dropboxusercontent.com/u/55589036/Pictures/Screenshots/20150210105510.png

How can I add the same margin to the right side as it appears on the left side?

Limit connections between shapes

Is there a way to limit which shapes can be connected?

For example, my diagram has three shapes, Ellipse, Hexagon and Star. Ellipse can be connected to Star and Hexagon can be connected to Star; however, Ellipse can never be connected to a Hexagon.

Get the source and target of a connection in runtime

How can I get the source and target of a connection in runtime?
I tried this event from RadDiagram ConnectionManipulationCompleted, but it gives me the target is null, while I'm sure I linked it to the second shape.
If there is a way to get all connections for for each RaddiagramShape it would be much better than hitting an event inside the RadDiagram.
Please, reply me as fast as possible.

Thank you.

locate a shape and change size according to zoom level

hello,

I need to dynamically mark on a map a few locations in the described way:
1. each location should be marked by a circle
2. the center of the circle should be the location (latitude and longtitude)
3. and the radius of the circle needs to be 4KM (4000 meters)

so when the user changes zoom level
the center of the circle should stay on the same exact location
and the radius should change according to the zoom level to reflect a 4KM at all times

i would also like the circles to be drawn dynamically, via code (not static file)
and also fade out after, lets say, 15 seconds

is that possible?
should i use mapshape? or hotspots?
should i use information layer or dynamic layer
i am very confused with all the options
can you please make an example like that?

i need to know if radmap supports such a scenario
and can manage that

thank you very much
i realy hope this can be done..
