Here is a simplified version of what i'm trying to achieve.

I have a product class with a collection of user defined fields

public class Product

{

    public string ProductName { get; set; }

    public string Category { get; set; }

    public List<UserDefinedField> userDefinedfields;

}

public class UserDefinedField

{

public string Name { get; set; }

public string Value { get; set; }

}

I can bind the name and category easily in Xaml.

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

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

I'd like to also bind the collection of user defined field to the end of the grid in code behind. I've tried this but no luck, the columns are created but no data is loaded.

foreach (UserDefinedField udf in products[0].UserDefinedFields)

{

ProductGrid.Columns.Add(

new GridViewDataColumn

{

Header = udf.Name,

DataMemberBinding = new Binding(udf.Value)

});

}

Thank you in advance.

Display tooltip for multiple charts simultaneously

Hi,

I am displaying multiple serie charts on a single page which all have the same categoryAxis. What I would like to do is display the tooltip in floating panel and crosshair for every chart when hovering over a single one.

I've synchronized TrackBall in every graphic, I've proved with TrackInfoUpdated event, but I've only get the information from one single graphic, not from all of them. Can I get the information from all set of points in this event? there are any other ideas to attach every point from different graphics?

Thanks,
Gerard

Testing without touchscreen

Hello,

is it possible to test an application that uses the Touchmanager events on a machine that has no touchscreen? My main development machine has no touchscreen and it is a little cumbersome to deploy the application for each test on the target device.

Is there a way to simulate at least the Tap-event with a mouse click?

Beste regards,
Thomas

Bind MapShapeData fill color

Hi,

Is there a way to bind the fill color of a map shape to a property of my DataContext but I can't do it. Here's what I've tried:

When I run, I have an error "Cannot find source for binding with reference ..." because MapSahpeFill doesn't inherit the "inheritance context".

So is there a way to achieve what I want ?

Thank you,

Etienne

ChartSeriesDataSource throwing ArgumentOutOfRangeException during data binding

I have a custom queue-like collection that implements INotifyCollectionChanged and IList<>. Rather than raising CollectionChanged for every Enqueue() operation, it raises CollectionChanged once for every 5 Enqueue() operations: NotifyCollectionChangedEventArgs.NewItems contains a list of the 5 items added since the last CollectionChanged call, and NotifyCollectionChangedEventArgs.NewStartingIndex is set to my collection's Count property - 5.

This collection is being used as a data binding source to a RadCartesianChart with a DateTimeContinuousAxis. Unfortunately, when my collection raises CollectionChanged, an ArgumentOutOfRangeException is thrown out of ChartSeriesDataSource.GenerateDataPoint(). It appears that ChartSeriesDataSource's internal List<> is out of sync with my collection. NotifyCollectionChangedEventArgs.NewStartingIndex lies within my collection, but is several indices (1-4) beyond the end of ChartSeriesDataSource's internal List<>.

Questions:

1. Does ChartSeriesDataSource (and ChartView generally) play nicely when it receives a NotifyCollectionChangedEventArgs.NewItems that contains more than one item? Especially if the source collection already contains data when the data binding is set up?

2. If not, is there another way to throttle ChartView's updates?

Open tool window and dragging it, to existing Rad daocking control

Hi,

1. I want to open a tool window with content.
2. after the tool window is shown, i want to docking it (by dragging) to existing radDaocking control.

I saw this telerik documentation for telerik winform:
ToolWindow windowTop = new ToolWindow();
windowTop.Text = "Window Top";
RadDocking radDock1 = new RadDocking();
this.radDock1.DockWindow(windowTop, DockPosition.Top);

what is the replacement code for this sample for telerik wpf?

(i don't have windowTop.Text neither radDock1.DockWindow(windowTop, DockPosition.Top))

Thanks

Remove gridlines for only specific columns

Hi,

Need to remove the vertical girdlines for only specific columns in the Grid. As pointed out in the attached grid screenshot we need to remove the last gridline.

Or can we make sure that existing column fill the entire space of the grid. [Already tried ColumnWidth = "*", not working ]

Any suggestion are welcome.

Thanks in advance

Telerik.Win Assembiles installed in my GAC - Correct MSI, or where to find it?

Hi there,

I'm working in a pretty big IT shop and it appears that 32 Telerik.WinControls where installed with version 2014.2.617.20 by one of the IT staff here.

The downstream issue I'm having is when trying to run the latest Telerik Demos App "Demos - Telerik UI for WPF", I get a DLL mismatch error.

Could not load file or assembly 'Telerik.Windows.Controls, Version=2016.1.112.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies, The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040).

I was able to trace back via my log files that this was the file that was used to install these assemblies: "Telerik_UI_for_WinForms_2014_2_617.msi"

I want to mainly run the demo app to show to influential business partners what Telerik Controls can do, but these current ones installed on my GAC are blocking me from using the WPF Demo App

Would the best course of action be to find this MSI somewhere, and un-install it, or download it from Telerik (if it still exists)?

Or, is the conflict something else?

Much appreciate any feedback someone can provide.

Cheers!

set hand cursor pointer on cell hover

Hello Telerik,

I am trying to accomplish this

http://www.telerik.com/forums/gridview-cell-mousehover-hand-cursor

but for WPF.

Basically set a hand cursor when it is hovering on the "Name" cell.

I want to do a link-like visual to my cell (if you could also help on this, much appreciated)

I have tried to handle events like

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" MouseEnter="GridViewDataColumn_MouseEnter" GotMouseCapture="GridViewDataColumn_GotMouseCapture" MouseMove="GridViewDataColumn_MouseMove" IsMouseCaptureWithinChanged="GridViewDataColumn_IsMouseCaptureWithinChanged" CellStyleSelector="{StaticResource NameLengthTemplateSelector}"/>

private void GridViewDataColumn_MouseEnter(object sender, System.Windows.Input.MouseEventArgs e)

{

}

private void GridViewDataColumn_GotMouseCapture(object sender, System.Windows.Input.MouseEventArgs e)

{

}

private void GridViewDataColumn_MouseMove(object sender, System.Windows.Input.MouseEventArgs e)

{

}

private void GridViewDataColumn_IsMouseCaptureWithinChanged(object sender, DependencyPropertyChangedEventArgs e)

{

}

but none of them gets hit by my breakpoint when I hover my cell

please help!

cheers

StyleManager.Theme does not exsist

I have an old .net application that is no longer supported or being devolped. I need to make some changes and would also like to fancy up the interface. I used justdecompile to decompile it but I am getting a lot of XAML errors -

The property 'StyleManager.Theme' does not exist in XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation'. Line 57 Position 116

.
The application uses

Telerik.Windows.Controls.Data.dll,Telerik.Windows.Controls.dll,Telerik.Windows.Controls.Docking.dll, Telerik.Windows.Controls.Input.dll, Telerik.Windows.Controls.Navigation.dll,Telerik.Windows.Data.dll

I ran the upgrade wizard on the project and it completed without any error I think it upgraded from Telerik version 2013. Can I upgrade this project to have no XAML and only use implictit styles?
