Project Upgrading to Visual Studio 2013

Hi all,

We use Telerik WPF suite version 2012.3.1129.40 and Telerik reporting suite .

Our customer wants to upgrade Visual Studio version from 2010 to 2013.

We opened and built our solution to Visual Studio 2013 and we couldn’t see any problem. It still works correctly.At least for now...

Do we need to upgrade Telerik ".dll" files or something like that? Or does it still works as it s expected?

Thanks in advance

Kerem

OnLostFocus virtual method not called

Hello,
I have created a new control that inherits RadAutoCompleteBox and I need to make some work when the control lost its focus.
I have written a OnLostFocus method that overrrides the base method, but it is unfortunately never called.
Is this a bug?

RadPropertyGrid: Creating a single visual property from a combination of 3 propertis (name, type and value)

Hi,

I've created a demo project that will demonstrate my current situation and my goal.

The code and XAML are attached below.

As you could see in the picture marked as "Desired display" and in propertyGrid2 in the code I had to create a mockup classes that will display the properties.

My goal is to get the "Desired display" look by using only the "MainObject" and "PropertiesObject".

The main issues I have are:
1. I need to translate the 3 properties from "PropertiesObject": "PropertyName", "PropertyType" and "PropertyValue" into a single property (without generating a new class on run time).
2. I need to make the observable collection nested properties display the list of "PropertiesObject" (after my conversion to a single property) without the extra nested properties (like Count).
3. I don't want to use or display the "CollectionEditor".

The amount and variety of the properties in the "OtherProperties" observable collection are unknown during compile-time and change during run-time from another source.

I do not require the ability to edit the properties so they can all be read-only.

Do you have any hints on how I can accomplish my goal?

This is the code I'm using:

using System;

using System.Collections.Generic;

using System.Collections.ObjectModel;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Data;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Imaging;

using System.Windows.Navigation;

using System.Windows.Shapes;

namespace TelerikPropertyGrid

{

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

PropertiesObject property1 = new PropertiesObject() { PropertyName = "stringProperty1", PropertyType = typeof(string), PropertyValue="string 1" };

PropertiesObject property2 = new PropertiesObject() { PropertyName = "stringProperty2", PropertyType = typeof(string), PropertyValue = "string 2" };

PropertiesObject property3 = new PropertiesObject() { PropertyName = "boolProperty1", PropertyType = typeof(bool), PropertyValue= (Boolean)true };

PropertiesObject property4 = new PropertiesObject() { PropertyName = "boolProperty2", PropertyType = typeof(bool), PropertyValue = (Boolean)false };

PropertiesObject property5 = new PropertiesObject() { PropertyName = "intProperty1", PropertyType = typeof(int), PropertyValue=(Int32)10 };

ObservableCollection<PropertiesObject> properties = new ObservableCollection<PropertiesObject>() { property1, property2, property3, property4, property5 };

MainObject main = new MainObject() { Name = "john", Age = 25, OtherProperties = properties };

//this is the property grid I have and want to modify using only MainObject and PropertiesObject classes

PropertyGrid1.Item = main;

PropertyGrid1.Visibility = System.Windows.Visibility.Visible;

//this proeprty grid demonstrates how I want my grid to look like.

//I created the "goal*" classes in order to populate it, I don't have those in the production system

PropertyGrid2.Item = new GoalDisplayObject();

PropertyGrid2.Visibility = System.Windows.Visibility.Hidden;

}

public class MainObject //exist in production

{

public string Name { get; set; }

public int Age { get; set; }

public ObservableCollection<PropertiesObject> OtherProperties { get; set; }

}

public class PropertiesObject //exist in production

{

public string PropertyName { get; set; }

public Type PropertyType { get; set; }

public object PropertyValue { get; set; }

}

public class GoalDisplayObject //doesn't exist in production

{

public string Name { get { return "john"; } set { } }

public int Age { get { return 25; } set { } }

public GoalNestedProperties OtherProperties { get { return new GoalNestedProperties(); } set { } }

}

public class GoalNestedProperties //doesn't exist in production

{

public bool boolProperty1 { get { return true; } set { } }

public bool boolProperty2 { get { return false; } set { } }

public string stringProperty1 { get { return "string 1"; } set { } }

public string stringProperty2 { get { return "string 2"; } set { } }

public int intProperty1 { get { return 10; } set { } }

public override string ToString() { return ""; }

}

And this is the XAML:

<Window x:Class="TelerikPropertyGrid.MainWindow"

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

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

xmlns:local="clr-namespace:TelerikPropertyGrid"

mc:Ignorable="d"

d:DesignHeight="300" d:DesignWidth="400">

<Grid x:Name="LayoutRoot" Background="White">

<telerik:RadPropertyGrid x:Name="PropertyGrid1" Grid.Row="0" NestedPropertiesVisibility="Visible" SortAndGroupButtonsVisibility="Collapsed" SearchBoxVisibility="Collapsed" FieldIndicatorVisibility="Collapsed" DescriptionPanelVisibility="Collapsed"/>

<telerik:RadPropertyGrid x:Name="PropertyGrid2" Grid.Row="0" AutoGeneratePropertyDefinitions="False" NestedPropertiesVisibility="Visible" SortAndGroupButtonsVisibility="Collapsed" SearchBoxVisibility="Collapsed" FieldIndicatorVisibility="Collapsed" DescriptionPanelVisibility="Collapsed">

<telerik:RadPropertyGrid.PropertyDefinitions>

<telerik:PropertyDefinition Binding="{Binding Name}" DisplayName="Name"/>

<telerik:PropertyDefinition Binding="{Binding Age}" DisplayName="Age"/>

<telerik:PropertyDefinition Binding="{Binding OtherProperties}" DisplayName="Other Properties" IsExpanded="True">

<telerik:PropertyDefinition.NestedProperties>

<telerik:PropertyDefinition Binding="{Binding boolProperty1}" DisplayName="boolProperty1"/>

<telerik:PropertyDefinition Binding="{Binding boolProperty2}" DisplayName="boolProperty2"/>

<telerik:PropertyDefinition Binding="{Binding stringProperty1}" DisplayName="stringProperty1"/>

<telerik:PropertyDefinition Binding="{Binding stringProperty2}" DisplayName="stringProperty2"/>

<telerik:PropertyDefinition Binding="{Binding intProperty1}" DisplayName="intProperty1"/>

</telerik:PropertyDefinition.NestedProperties>

</telerik:PropertyDefinition>

</telerik:RadPropertyGrid.PropertyDefinitions>

</telerik:RadPropertyGrid>

</Grid>

</Window>

Thanks in advance,

Group Footer aggregates not updating

I've run into some very strange problem.

I have several Aggregage SumFunctions in my grid. When I group on a column, the group footer aggregates show, but will not update. The numbers stay the same no matter what changes I make.

The aggregates at the bottom of the grid update fine. I'm only having problems with group footer aggregates.

I have seen other posts about this issue, but you claim the issue was resolved in an update. I am on v2012.2.725.40 of the WPF controls and using Visual Studio 2010.

RadRichTextBox loading performance issue

Hi everyone,

We have a window that contains a RadRichTextBox and it is loaded on demand, we've noticed that it takes a long time to load, around 20s, the first time, after that it loads fast.

checking on the output we found that the following module takes the entire load time.

'XXXX.exe' (CLR v4.0.30319: XXXX.exe): Loaded 'MetadataViewProxies_09fc4bbd-18cb-4607-8b8c-a7d449e27c43'.

We guessed that it is related to MEF, anything on how we might fix this, by disabling probably unneeded features. Not all features are needed for our case.

we are using the following version: 2013.3.1016.40

Regards
Abdelkarim

Not able to re-size a diagram shape above 10000

Hi

We are using Diagram control and have Diagramshape inside this control. Now when we try to re-size this shape using SettingsPane the maximum width and height of the shape can reach only up to 10,000 and does not go beyond that.
Is there some way by which we can get rid of any restriction on the size of diagramshape using SettingsPane.

Regards
JC

ScheduleView rendering speed problem.

Hi,

I already post a thread about this issue, please ignore it!!

my SchedulView control display from Monday to Friday, from 8:00 AM to 9:00 PM with a MinorTickLength of 15 minutes and of course we can have more than one resources per day. I would like to know which approach should I use to optimize the performance of the rendering? Ideally, I would like to display a UserControl inside each cells, each cells can be a closed slot, a special slot or an appointment.

thank you

Al

What is this in the GridViewHeader and where is its style/template?!

Hi all,

We're trying to create a completely borderless, minimalist gridview and have almost got it. The only problm remaining is a strange gradient...widget?...that appears only in the first column of the RadGridView. The picture with the red arrow points to what I'm referring to. What is this element? What is its template and/or style? We've gone through the GridViewHeader, GridViewHeaderRow, and GridView itself.
