Seperate Collection binding per GridViewDataColumn possible?

Hello,

I’ve started my RadControl a few days ago and I’am delighted by the number feature and mature design of the components.
However I've also just started with WPF UI Development, so my learning curve is still steep and maybe you can help me with a Data Binding problem/misunderstanding of mine:
I've got a RadGridView (inside a Data Template) in an MVVM Application, and I’m trying to bind an Observable Collection to a GridViewData Column. Please take a look at my following Models and View-Models (I’ve stripped out unnecessary code):

//Part of the ViewModel - Begin

private ObservableCollection<ProductCategoryModel> _planCollection = null;

public ViewModel()

{

//ViewModel Constructor

_planCollection = new ObservableCollection<ProductCategoryModel>

{

new ProductCategoryModel("AlphaPlan"),

new ProductCategoryModel("BetaPlan")

}

public ObservableCollection<ProductCategoryModel> PlanCollection

{

get { return _planCollection; }

set { _planCollection = value; }

}

public ObservableCollection<CalendarWeek> AlphaPlan

{

get { return _planCollection[0].Numbers; }

set { throw new NotImplementedException(); }

}

public ObservableCollection<CalendarWeek> BetaPlan

{

get { return _planCollection[1].Numbers; }

set { throw new NotImplementedException(); }

}

//Part of the ViewModel - End

//The Models - Begin

public class CalendarWeek : INotifyPropertyChanged

{

public CalendarWeek(int week, float value)

{

this.Week = week;

this.Value = value;

}

[Display(AutoGenerateField = false)]

public int Week { get; set; }

[DisplayAttribute(Name = "Value")]

public double Value { get; set; }

}

public class ProductCategoryModel

{

public ProductCategoryModel(string leName)

{

this.Product = leName;

this.Numbers = new ObservableCollection<CalendarWeek>();

for (int i = 1; i <= 52; i++)

{

Random r = new Random(Guid.NewGuid().GetHashCode());

int rInt = r.Next(0, 100);

this.Numbers.Add(new CalendarWeek(i, rInt));

}

public ObservableCollection<CalendarWeek> Numbers { get; set; }

public string Product { get; set; }

}

//The Models - End

I want to put these Collections in one RadGridView (as you can see, I just want the Values member from the CalendarWeek in the Column).
I have tried many approaches I have stumbled across the RadControl Help, Forums or on StackOverflow, but none seems too work (or I missed the right combination) for me.

What are your preferred approach here?

Hierarchical? Master Detail Binding? Creating my own GridViewDataColumn Template/Style?

Thanks a lot and happy Holidays for all of you :)

Multi Column CombBox

Hi Team,
I want a multi column combobox, for this i create a combobox and define gridview as RadcomboboxItem. It works fine, but I am unable to filter gridview. I want a multicolumn combobox, which can filter columns. I RadGridView1_SelectionChanged event to set selected value.
Your Quick response will be highly appreciated.

Following is Xmal Code:


<telerik:RadComboBox Name="rcbNew" Grid.Row="0" 
                          IsEditable="True" Height="25" Width="200">
            <telerik:RadComboBox.Items> 
                <telerik:RadComboBoxItem> 
                    <telerik:RadComboBoxItem.Template> 
                        <ControlTemplate> 
                            <my1:RadGridView x:Name="RadGridView1" ShowGroupPanel="False" CanUserFreezeColumns="False" 
                                             RowIndicatorVisibility="Collapsed" IsReadOnly="True"
                                             IsFilteringAllowed="False" ItemsSource="{Binding .}"
                                             Width="200" Height="150" SelectionChanged="RadGridView1_SelectionChanged" >
                            </my1:RadGridView> 
                        </ControlTemplate> 
                    </telerik:RadComboBoxItem.Template> 
                </telerik:RadComboBoxItem> 
            </telerik:RadComboBox.Items> 
        </telerik:RadComboBox>

Here follwoing code:

DependencyProperty currentSelectedValue = DependencyProperty.Register("rcbNewSelectedValue", typeof(Int32), typeof(Int32));

        // Constructor

 public GridinDropDown() 
        {
 
            InitializeComponent();
 
            IList<Company> MyObject; 
 
 
 
            MyObject = new List<Company>()
 
            {
 
                new Company { Id=1, Name="Description1" },
 
                new Company { Id=2, Name="Description2" },
 
                new Company { Id=3, Name="Description3" },
 
                new Company { Id=4, Name="Description4" }
 
            };
 
 
 
            this.DataContext = MyObject;
 
        }




private void RadGridView1_SelectionChanged(object sender, Telerik.Windows.Controls.SelectionChangeEventArgs e) 
        {
 
            rcbNew.Text = ((Company)((Telerik.Windows.Controls.GridView.GridViewDataControl)sender).SelectedItem).Name;
 
            rcbNew.SetValue(currentSelectedValue, ((Company)((Telerik.Windows.Controls.GridView.GridViewDataControl)sender).SelectedItem).Id);// = ((Company)((Telerik.Windows.Controls.GridView.GridViewDataControl)sender).SelectedItem).Id;
 
            rcbNew.IsDropDownOpen = false;
 
        }

Data Formatting

Hello!

According to demo WPF->GridView->Appearance->Data Formatting I can set DataTemplate as CellTemplate.

Everything works fine. But what should I do if I want my DataTemplate fill cell?

For example, this code will show me empty cell:

<telerik:GridViewDataColumn.CellTemplate>
<DataTemplate>
<Grid Background="DarkMagenta"/>
</DataTemplate>
</telerik:GridViewDataColumn.CellTemplate>

instead of filling all empty space.

Error Using telerik:ThemeResourceKey

I have a ResourceDictionary xaml file that I use for centralized styling. In it I'm trying to use the style below but am getting an error:
Error 1 The type 'telerik:ThemeResourceKey' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built. C:\Development\BestpassEM\WPFInfrastructure\Styles\ControlStyles.xaml 36 65 Miscellaneous Files
I have the namespace def at the top of my file (xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" ) what else would I need?

I did have this working but then had to switch my target framework from 4.0 Client Profile to the full verion of 4.0 (to support the telerik ReportViewer control). What could that have broken?

<Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource {telerik:ThemeResourceKey ThemeType=telerik:Windows7Theme, ElementType=TextBox}}" x:Key="EditTextStyle">

<Setter Property="HorizontalAlignment" Value="Left" />

<Setter Property="Margin" Value="2" />

<Setter Property="Foreground" Value="#333333" />

<!--<Setter Property="Height" Value="22" />

<Setter Property="BorderBrush" Value="{StaticResource ControlOuterBorder_Normal}" />-->

<Setter Property="Validation.ErrorTemplate" Value="{StaticResource validationTemplate}"/>

<Style.Triggers>

<Trigger Property="Validation.HasError" Value="True">

<Setter Property="ToolTip"

Value="{Binding RelativeSource={RelativeSource Self},

Path=(Validation.Errors).CurrentItem.ErrorContent}"/>

</Trigger>

</Style.Triggers>

</Style>

Text is no longer left-aligned when editing in RadMaskedNumberInput

Here's my xaml:

<telerik:RadMaskedNumericInput HorizontalAlignment="Stretch" Grid.Row="3" Grid.Column="1" Value="{Binding Port}"

IsClearButtonVisible="False" IsEnabled="{Binding IsReady}" Margin="0,5,0,0" Mask="d5"

AutoFillNumberGroupSeparators="False" AllowSkipPlaceholders="False" HorizontalContentAlignment="Left"

SelectionOnFocus="CaretToBeginning" Placeholder=" " AutoFillZeros="False" TextMode="PlainText"

InputBehavior="Insert"/>

This is a simple text field for a TCP/IP port. It should have 5 digits. When the input field is not in focus and the port is only 4 digits (e.g. 8000) the text is left-aligned. When the input field is in focus and being edited, it places what I believe is a placeholder for the empty left-most digit. It really should just leave it as a left-aligned 4-digit number. This is truly annoying.

In general, this control is horribly complicated and could be made simpler by making much of the above xaml the default values.

Drag map items in RadMap

Hello,

I have a RadMap with many information layers. I want to change any map item location by dragging it to a new position. I looked at DragDropManager but I don't think it's suitable for my needs, it seems to be more usefull for transferring data from one control (or application) to another rather than for changing location.

Is DragDropManager the way to go or should I use MouseMove events?
Also, is there any good example of a solution to my problem ?

Thanks
