How to get the diagram position from a mouse click

Hi,

We display a context menu when the user right clicks a location within the RadDiagram. How would we get the position in the diagram where the user clicked?
This doesn't appear to be as simple as getting the MousePosition of the menu (or combining it with PointFromScreen) as we need to take account of Pan / Zoom / Scrolling.

Link inside Radscheduleview to display a gridview with db data

Hi,
How can I put a link inside slots and display data on a pop up gridview when click. The info for the slot will get populated from db, including its color (Category) , Not sure how to change or assign a color from code behind. The color is coming from db as arg, The user preselect the message to display and the color category at othe window.....

The use of the link and grid inside a slot is to display data related to the message displayed.

Thanks in advance!

Saving Merge Fields in saved docx

I am trying to save a Word document that has merge fields, but do not want the merging done. It appears that the merging is done before the document is saved so that that when it is reopened, cannot then perform the merge. Am I doing something wrong?

Autocomplete's textbox clearing issue

Hi Guys,
I'm using RadAutocompleteBox from RadControls for WPF Q3 2012 in an MVVM Application.
Here is sample code:

<Controls:AutoCompleteBox

WatermarkContent="Select a location..."

DisplayMemberPath="Name"

TextSearchPath="Name"

SelectedItem="{Binding ImpactedLocation, Mode=TwoWay, ValidatesOnDataErrors=True}"

ItemsSource="{Binding AvailableImpactedLocations}"

IsEnabled="{Binding IsOpened}"

MaxDropDownHeight="400"

DropDownWidth="400"

/>

The SelectedItem is bound to an MVVM ViewModel.
My problem is when I want to clear the text displayed in the autocomplete's textbox by setting the ViewModel.ImpactedLocation = null;
the selectedItem is cleared, but the text displayed is still here.

How can I clear it please? Something's to do with the SearchText? (try to clear it too, but still not working)
Thank's for your help.
Kind regards,
JC

LinearScale: CustomItems spanning range

LinearScale.CustomItems spanning range

Is it possible to have a custom item inside a linear scale span a certain range of values?
When you use the attached property ScaleObject.Value, it centers the item at the specified value. However, I would like to have the left end of the item (e.g. an rectangle or border) at one value and the right end at another.

Thank you.

Easy way to Clone columns

Hi I'm using 2013.2.

Currently I'm using 2 RadGridView:
1st MainGridView and 2nd SelectedGridView.

The 1st is the main UI control, and 2nd is just for getting the AggregationResults of the selected rows in the 1st RadGridView.
So basically the 2nd is not on the UI.

I am trying to make the 2nd grid has the same columns with AggregationFunctions as the 1st grid has.
So I hope to have an easy way of Cloning the column dependency object instance from the 1st grid and add them into the 2nd grid, hence, I could easily get the AggregationResults of the selected rows of the 1st grid.

Thanks

Configure LegendItems using RadLegend and RadPieChart

Hi,

I am trying to configure the legend items shown in a RadLegend control associated to a RadPieChart.

This is how I load the data:

<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="WpfApplication1.MainWindow"

Title="MainWindow" Height="594.024" Width="902.888">

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="*"/>

</Grid.ColumnDefinitions>

<telerik:RadPieChart Name="PieChartDemo" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" Height="543" Width="428"/>

<telerik:RadLegend x:Name="PieLegend"

Grid.Column="1" Items="{Binding LegendItems, ElementName=PieChartDemo}"/>

</Grid>

</Window>

public MainWindow()

{

InitializeComponent();

FillPieChart();

}

void FillPieChart()

{

DataTable dtData = new DataTable("DATA");

dtData.Columns.Add(new DataColumn("Name", typeof(string)));

dtData.Columns.Add(new DataColumn("Value", typeof(double)));

dtData.Rows.Add(new object[] { "Scrap", 5429287.5 });

dtData.Rows.Add(new object[] { "KWH", 713631 });

dtData.Rows.Add(new object[] { "Electrode", 327349 });

dtData.Rows.Add(new object[] { "Alloys", 2372722.3 });

dtData.Rows.Add(new object[] { "Fluxes", 317157.65 });

dtData.Rows.Add(new object[] { "Labor", 300084.1 });

PieChartDemo.Palette = ChartPalettes.Arctic;

PieSeries pieSer = new PieSeries();

pieSer.ShowLabels = true;

foreach (DataRow drCost in dtData.Rows)

{

pieSer.DataPoints.Add(new PieDataPoint()

{

Value = double.Parse(drCost["Value"].ToString()),

Label = string.Format("{0}\n{1:N} K", drCost["Name"].ToString(), double.Parse(drCost["Value"].ToString()) / 1000.00)

}

);

}

pieSer.LabelDefinitions.Add(new ChartSeriesLabelDefinition() { Margin = new Thickness(-5, 0, 0, 0) });

pieSer.AngleRange = new AngleRange(270, 360);

pieSer.LegendSettings = new DataPointLegendSettings();

PieChartDemo.Series.Clear();

PieChartDemo.Series.Add(pieSer);

}

I am creating a PieSeries and adding some PieDataPoint. For each data point I add the value and the label, and I think the RadLegend takes this label to show its items. Am I correct?

In the beginning I wasn't using the RadLegend so I was showing the name and the value in the chart, assigning both values to Label:

pieSer.DataPoints.Add(new PieDataPoint()

{

Value = double.Parse(drCost["Value"].ToString()),

Label = string.Format("{0}\n{1:N} K", drCost["Name"].ToString(), double.Parse(drCost["Value"].ToString()) / 1000.00)

}

And then I added the RadLegend Control and it shows the same values.

How can I configure the RadLegend control to show only the names if I change the Label shown in the RadPieChart to show only the values?

DataFormComboBoxField in a RadDataForm

I have followed the example below and scoured the internet for 2 days trying to get my combobox to work correctly, and I still cannot get it to select the correct item when the form opens. http://www.telerik.com/help/silverlight/raddatafor-edit-lookup-values-with-radcombobox.html

I have two classes (generated by the Openaccess ORM), one of which contains information about musicians (name, id, genre etc) and a second class that contains information about the type of musician (band, festival, performing arts etc). I have successfully added a couple of simple textbox controls to the form that display the artist name and some other basic information, and now I am trying to pick the artist type from a combo box.

I can successfully populate the combobox from the ORM model "ArtistType" class, but no matter what I do it always opens either with the first item selected (regardless of the actual underlying value) or nothing selected at all. If I break the code in the combobox_Loaded event, I can see the values, but they are never reflected in the combobox.

How can I databind a simple numeric value in a primary table to a list of items in a second table to be displayed as a picklist in a combox?

Merge Only Telerik Assemblies into WPF Executable

Some people on here are probably familiar with this blog entry about Merging Telerik's Assemblies into an WPF executable. We actually decided to take a completely different spin and wanted to just merge the Telerik assemblies only leaving all our others untouched (our program as a plug-gable module architecture so we can't merge ALL assemblies). I'm not sure if any one else would be interested in this but I wanted to post it anyway just to get it out there that it is possible.

MSBuild AfterResolveReferences:

<Target Name="AfterResolveReferences">

<ItemGroup>

<EmbeddedResource Include="@(ReferenceCopyLocalPaths)" Condition=

"$([System.Text.RegularExpressions.Regex]::IsMatch(%(ReferenceCopyLocalPaths.Filename), 'Telerik')) And '%(ReferenceCopyLocalPaths.Extension)' == '.dll'"

>

<LogicalName

>%(ReferenceCopyLocalPaths.DestinationSubDirectory)%(ReferenceCopyLocalPaths.Filename)%(ReferenceCopyLocalPaths.Extension)</

LogicalName>

</EmbeddedResource>

</ItemGroup>

</Target>

Program.cs:

namespace WpfApplication1

{

using System;

using System.Collections.Generic;

using System.Linq;

using System.Reflection;

public class Program

{

[STAThreadAttribute]

public static void Main()

{

var assemblies = new Dictionary<string, Assembly>();

var executingAssembly = Assembly.GetExecutingAssembly();

var resources = executingAssembly.GetManifestResourceNames().Where(n => n.StartsWith("Telerik")).Where(n => n.EndsWith(".dll"));

foreach (string resource in resources)

{

using (var stream = executingAssembly.GetManifestResourceStream(resource))

{

if (stream == null)

continue;

var bytes = new byte[stream.Length];

stream.Read(bytes, 0, bytes.Length);

try

{

assemblies.Add(resource, Assembly.Load(bytes));

}

catch (Exception ex)

{

System.Diagnostics.Debug.Print(string.Format("Failed to load: {0}, Exception: {1}", resource, ex.Message));

}

AppDomain.CurrentDomain.AssemblyResolve += (s, e) =>

{

var assemblyName = new AssemblyName(e.Name);

var path = string.Format("{0}.dll", assemblyName.Name);

if (assemblies.ContainsKey(path))

{

return assemblies[path];

}

return null;

};

App.Main();

}

We also did an additional spin with a PostBuildEvent of deleting the Telerik files after the build.

PostBuildEvent:

<PropertyGroup>

<PostBuildEvent>del /F /Q "$(TargetDir)Telerik*"

rmdir /S /Q "$(TargetDir)de"

rmdir /S /Q "$(TargetDir)es"

rmdir /S /Q "$(TargetDir)fr"

rmdir /S /Q "$(TargetDir)it"

rmdir /S /Q "$(TargetDir)nl"

rmdir /S /Q "$(TargetDir)tr"</PostBuildEvent>

</PropertyGroup>

I hope someone else finds this useful as we did.
