Dragging chart on which datapoints get updated

Hi,
Thanks for the wonderful chart control provided from telerik. Is there a feature like dragging the chart area and datapoints gets updated depending on the drag.

Scenario:
1. RadCartesianChart holding queue with 1000 data points.
2. But the current chart view shows only latest 10 points.
3. If drag the chart area to left/right, then data points must get updated. (this must depend on drag sensitivity).
4. This is some thing like playing the chart area w.r.t to datapoints in the queue.
5. Should have an event warning me that i am at point 0 and point 1000 on the graph. (start and end of the queue).

Please reply AS SOON AS POSSIBLE.

Thanks,
Supriya

Adding a column dynamically with mvvm pattern

Hi guys

Ok two basic classes:

using System;

using System.Collections.Generic;

using System.Collections.ObjectModel;

using System.Linq;

using System.Text;

namespace ProjectMaster.Core.Business

{

public class Project

{

#region Fields

private string _name;

private double _budget;

private DateTime _startDate;

private DateTime _finishDate;

private int _duration;

private ObservableCollection<Phase> _phases;

#endregion

#region Properties

public string Name

{

get { return _name; }

set { _name = value; }

}

public double Budget

{

get { return _budget; }

set { _budget = value; }

}

public DateTime StartDate

{

get { return _startDate; }

set { _startDate = value; }

}

public DateTime FinishDate

{

get { return _finishDate; }

set { _finishDate = value; }

}

public int Duration

{

get

{

_duration = (_finishDate - _startDate).Days;

return _duration;

}

set { _duration = value; }

}

public ObservableCollection<Phase> Phases

{

get { return _phases; }

set { _phases = value; }

}

#endregion

public Project(string name, int budget, DateTime startDate, DateTime finishDate)

{

this._name = name;

this._budget = budget;

this._startDate = startDate;

this._finishDate = finishDate;

_phases = new ObservableCollection<Phase>();

}

using System;

using System.Collections.Generic;

using System.Collections.ObjectModel;

using System.Linq;

using System.Text;

namespace ProjectMaster.Core.Business

{

public class Phase

{

#region Fields

private string _name { get; set; }

private double _budget { get; set; }

private DateTime _startDate { get; set; }

private DateTime _finishDate { get; set; }

private int _duration { get; set; }

private ObservableCollection<Task> _tasks { get; set; }

#endregion

#region Properties

public string Name

{

get { return _name; }

set { _name = value; }

}

public double Budget

{

get { return _budget; }

set { _budget = value; }

}

public DateTime StartDate

{

get { return _startDate; }

set { _startDate = value; }

}

public DateTime FinishDate

{

get { return _finishDate; }

set { _finishDate = value; }

}

public int Duration

{

get

{

_duration = (_finishDate - _startDate).Days;

return _duration;

}

set { _duration = value; }

}

public ObservableCollection<Task> Tasks

{

get { return _tasks; }

set { _tasks = value; }

}

public Phase(string name, int budget, DateTime startDate, DateTime finishDate)

{

this._name = name;

this._budget = budget;

this._startDate = startDate;

this._finishDate = finishDate;

_tasks = new ObservableCollection<Task>();

}

#endregion

}

And the xaml that binds these classes to a RadTreeListView to get the expected output:

<telerik:RadTreeListView Grid.Row="2" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="6,0,0,0" AutoGenerateColumns="True" ItemsSource="{Binding Project, Mode=TwoWay}" SelectedItem="{Binding Item}">

<telerik:RadTreeListView.ChildTableDefinitions>

<telerik:TreeListViewTableDefinition ItemsSource="{Binding Phases}"/>

<telerik:TreeListViewTableDefinition ItemsSource="{Binding Tasks}"/>

</telerik:RadTreeListView.ChildTableDefinitions>

<telerik:RadTreeListView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" Header="Name" />

<telerik:GridViewDataColumn Header="Start Date" DataType="{x:Type System:DateTime}">

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<telerik:RadDatePicker SelectedValue="{Binding StartDate, Mode=TwoWay}" />

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

</telerik:GridViewDataColumn>

<telerik:GridViewDataColumn Header="Finish Date" DataType="{x:Type System:DateTime}">

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<telerik:RadDatePicker SelectedValue="{Binding FinishDate, Mode=TwoWay}" />

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

</telerik:GridViewDataColumn>

<telerik:GridViewDataColumn Header="Duration" DataMemberBinding="{Binding Duration}" DataType="{x:Type System:Int32}" />

<telerik:GridViewDataColumn Header="Budget (Hrs)" DataMemberBinding="{Binding Budget}" DataType="{x:Type System:Double}" />

</telerik:RadTreeListView.Columns>

</telerik:RadTreeListView>

I've attached an image to show what the output is like.

Not what I want to be able to do is if the user clicks on a button, a new column is added to the TreeListVIew for eg a Resource column. Im really not sure how to go about this so any help/tips to get me in the right direction will be greatly appreciated!!

Thanking you in Advance!

RadTileView Horizontal Scrollbar not visible

I have a simple implementation of a RadTileView.

The tile view is contained within a radpane which is docked.

If a drag the pane out of the docking area so the pane is floating I see both vertical and horizontal scrollbars.

But, if I maximize one of the TileViewItems and then drag the pane out of the docking area so it is floating I see the vertical scrollbar but not the horizontal scrollbar.

Please advise.

Sorting ItemPropertyDefinition.DisplayName

Hi,

I am creating the ItemPropertyDefinition(s) in code-behind. I add the definitions one at a time based on various user selections peculiar to my app. As I add a ItemPropertyDefinition to the ItemPropertyDefinitions collection, I would like the ItemPropertyDefinition display names to be presented in alphabetical order. Can this be done?

Thanks
Rich
