I can drad panes, it is no problem, but how can I move panes without drag pan from group?

I hope it problem have solution.

Adding Custom Connectors in XAML style

In the documentation all custom connectors are added in code behind http://docs.telerik.com/devtools/wpf/controls/raddiagram/features/custom-connectors.html

I have also seen custom connectors added to individual raddiagramshape in xaml as :-

<telerik:RadDiagramShape Content="2"
Position="300 100"
UseDefaultConnectors="False">
<telerik:RadDiagramShape.Connectors>
<telerik:RadDiagramConnector Name="TopLeft"
Offset="1 0.33" />
</telerik:RadDiagramShape.Connectors>
</telerik:RadDiagramShape>

However I use MVVM model and a shape style selector and do not have direct access. I cannot set 'Connectors' in a style using 'Settter Property=' because the connectors collection only has a get accessor.

Is there a way to add custom connectors to a raddiagramshape in the XAML style?

telerik:RadDiagramShape Content="2"

Position="300 100"

UseDefaultConnectors="False">

<telerik:RadDiagramShape.Connectors>

<telerik:RadDiagramConnector Name="Left"

Tag="Connector 1"

Offset="0 0.5" />

<telerik:RadDiagramConnector Name="Top"

Tag="Connector 2"

Offset="0.5 0" />

<telerik:RadDiagramConnector Name="Right"

Tag="Connector 3"

Offset="1 0.5" />

<telerik:RadDiagramConnector Name="Bottom"

Tag="Connector 4"

Offset="0.5 1" />

<telerik:RadDiagramConnector Name="Auto"

Tag="Connector 5"

Offset="0.5 0.5" />

</telerik:RadDiagramShape.Connectors>

</telerik:RadDiagramShape>

<telerik:RadDiagramShape Content="2"

CodedUI Support

Hey guys,

So I have the 2013 Q3 version of WPF controls. What I'm trying to do at this point is to use the Telerik.VisualStudio.TestTools.UITest.Extension.ExtensionsCore.dll so that I can access more properties in my radcontrols for CodedUI tests. I have followed the steps on the following web page: http://www.telerik.com/help/wpf/coded-ui-support.html. This seems to work fine for RadButtons and a couple other simple controls however when I try to select a cell in a RadGridView I get the following error in the CodedUI Builder tool:

"you do not have sufficient privileges to access the information about this control or the control is part of the recorder process"

Of course I googled the issue and found that this problem typically comes from not running your application AND Visual Studio as administrator. So I restarted VS and ran it as Administrator and I also opened up my application as Administrator but it continues to have this error. The odd thing is that I can definitely access RadButtons and other controls, just not a RadGridView. According to the web page above, RadGridView is definitely a supported control so that should work and this article http://blogs.msdn.com/b/visualstudioalm/archive/2011/10/28/coded-ui-test-extension-for-3rd-party-controls-the-basics-explained.aspx also indicates that RadGridView is supported in CodedUI Tests.

I'm running:

Windows 8.1
Visual Studio 2012 Ultimate Update 4
WPF project in .Net 4.5
Telerik Rad Controls for WPF Q3 2013 (4.5)

Can anyone help?

GridView Row Grouping/Merging

I see that this same question was asked in March 2013 and the response there was that this would be in an upcoming release. As far as I can see in the latest WPF Demo , this is not available.

The scenario is simple. I am using the GridView to implement a logsheet type application. So I have some kind of time going down the left hand side of the grid (hourly or daily etc) and then columns similar to the "Merged Column Headers" demo.

But now some users might want to see the columns and rows switched, meaning that the date now runs across the top of the Grid as column headers and the grouped/merged column headers become row headers.

Is this possible? If not when will it be available because this is like standard functionality that any grid should have. The availability of this functionality will determine if we continue with our license.

Thanx.

Intermediate dialog in radlistbox drag and drop

Hi all,

I am trying to implement a feature whereby the user will drag an item from one list box and when they dump it into the other, before it is dumped, they will get a dialog which will ask them to set one of the properties of the item they wish to transfer. I am currently trying to abuse a dataconverter but it doesn't seem to be working.

Thanks,

Julian

Binding GridViewDataColumn.Header to model property fails

Hi,

I'm really pulling my hair with this one, so any help I can get would be greatly appreciated!

Here is the thing... I am using MVVM and I need to create a grid with (to start with) one row and a variable number of columns. The name of the columns are based on property values in an object (see "ProductVariantFacade" below), so I need to set the name of the columns after the grid has been initialized. So I started out using an ObservableCollection<ProductVariantFacade> in my view model, like so:

public ObservableCollection<ProductVariantFacade> ProductVariantFacades { get; set; }

Where ProductVariantFacade looks like this:

public class ProductVariantFacade : FacadeBase

{

public ProductVariantFacade()

{

Data = new List<ProductVariantData>();

}

private string rowName;

public string RowName

{

get { return rowName; }

set

{

if (value != rowName)

{

rowName = value;

OnPropertyChanged("RowName");

}

public List<ProductVariantData> Data { get; set; }

public void AddData(string headerName, string value)

{

Data.Add(new ProductVariantData { HeaderName = headerName, Value = value });

}

public class ProductVariantData : FacadeBase

{

private string value;

public string Value

{

get { return this.value; }

set

{

if (value != this.value)

{

this.value = value;

OnPropertyChanged("Value");

}

private string headerName;

public string HeaderName

{

get { return headerName; }

set

{

if (value != headerName)

{

headerName = value;

OnPropertyChanged("HeaderName");

}

The inherited FacadeBase implements INotifyPropertyChanged. Then my RadGridView's columns are set up as so:

<telerik:RadGridView Name="VariantDetailsGrid"

AutoGenerateColumns="False"

Height="130"

IsReadOnly="False"

ItemsSource="{Binding ProductVariantFacades, Mode=TwoWay}"

>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding RowName}" Header="" DataType="{x:Type sys:String}"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Data[0].Value}" DataType="{x:Type sys:String}">

<telerik:GridViewDataColumn.Header>

<TextBlock Text="{Binding ProductVariantFacades[0].Data[0].HeaderName, Mode=TwoWay, Source={StaticResource ProductViewModel}}" />

</telerik:GridViewDataColumn.Header>

</telerik:GridViewDataColumn>

<telerik:RadGridView.Columns>

</telerik:RadGridView>

I was hoping that when I set my ObservableCollection ProductVariantFacades in my view model, the name of the column (the header) would be updated as well. That is, when the ProductVariantFacades[0].Data[0].HeaderName is set to a value. But for some reason this doesn't work. If I via a Button change the value of e.g. ProductVariantFacades[0].Data[0].Value it gets updated in the grid. But the header does not get updated when I change it. Any idea as to why?

Could it have anything to do with that the DataContext of TextBlock is not the same as for the rest of the view? E.g. not the same as the DataContext that the Data[0].Value is "connected" to?

Please help, thanks!

self-referencing-hierarchy-that-is-n-levels-deep in RadTreeListView

Hello,

I'm doing a project which need a n level deep in RadTreeListView. The first level I get a list of sector (ex: Asia, Europe, America). For the second sector: if it has the information (ex: Europe -> Est Europe, West Europe), I will show it ("Est europe", "West Europe" are the children of "Europe"). Then I may get still the third, fourth, fifth sector.

I have seen a old topic which talk about this, (see the link: http://www.telerik.com/forums/self-referencing-hierarchy-that-is-n-levels-deep#HN4SgZblU0eBamdGcvLWiQ) and I succeed to run this example, but there are always the children sector show in the first sector ("Sally Smith", "Fred Smith" should show only in the second level subsector and his father is "John Smith", "Emma Smith" should only show in the third level subsector and his father is "Sally Smith", see in the attach files to get more details). So I want to know how to fix this issue?

Search in treeview

Hi,

I have a treeview with nodes populated with only strings. Attached the node structure. Now, how can I acheive search capability through recursive search in node structure. I have gone through http://docs.telerik.com/devtools/wpf/controls/radtreeview/how-to/bring-path-into-view, but this uses index mechanism and only for numericals.

Any suggestions on how to search for a string in recursive and bring into path. Please provide your inputs.

Thanks,

Subhashini
