FilterDescriptor Collection & Model-View-ViewModel

I'm using an MVVM approach to an application. My Window has a textbox, a button, and a grid. When i click the button, i would like it to filter the grid based on the text inputted in the textbox. I realize the grid has built in filtering, but its more than likely too complicated for our end users.

    
                <Grid> 
        
                    <Grid.DataContext> 
        
                        <Binding Source="{StaticResource MyDataContext}" Mode="OneWay"  /> 
        
                    </Grid.DataContext> 
        
                        <telerik:RadGridView  Margin="12,55,12,58" AutoGenerateColumns="True"    Name="RadGridView1" > 
        
                        <telerik:RadGridView.ItemsSource> 
        
                            <Binding Path="Records" Mode="TwoWay" /> 
        
                        </telerik:RadGridView.ItemsSource>      
        
                    </telerik:RadGridView> 
        
                    <TextBox Height="23" HorizontalAlignment="Left" Margin="16,14,0,0" Text="{Binding SearchText}" Name="TextBox1" VerticalAlignment="Top" Width="120" /> 
        
                    <Button Height="23" HorizontalAlignment="Right" Margin="0,14,61,0" Command="{Binding SearchCommand}" Name="Button1" VerticalAlignment="Top" Width="75">Button</Button> 
        
                </Grid>

Is there any way to expose the FilterDescriptors Collection via a binding property so i can add to it and apply the filter, since i don't have access to RadGridView1.FilterDescriptors in my code? This would be similar to how the textbox exposes it's text property.

Is there a way to expose the ColumnCollection or SortDescriptors?

Binding 2 controls to 1 source

Hello, I'm binding 2 TreeView controls to one source, and only 1 TreeView has data, the other is empty.
Here's my code.

radTreeview1.ItemsSource = MyClass.Children;
radTreeview2.ItemsSource = MyClass.Children;

radTreeview1 is blank. If I comment out radTreeview2, radTreeview1 displays with data, so it looks like the last item to bind will work.

Can I not use the same class to bind to 2 different controls?

Thanks,
Scott

MVVM - Control color of area series on dynamically generated graph

I am generating 2 to 4 area series dynamically by referring below link from telerik documentation:

http://www.telerik.com/help/wpf/radchartview-features-chartseriesprovider.html

But these dynamic area series are showing default colors.

Is there a property I could use to control the color of dynamically generated Area series? My application is using MVVM pattern.

Visual issue with resizing of form with chart control.

Hi.

Is there any solution to avoid heaviest redraw and flickering during form resize operations in cases when charting control placed on form?
I noticed this strange behaviour only on chart control. Issues easily reproduced on your demo sample (zoom.zip). Launch it and try to resize form with mouse.
You can notice here not painted background appears on new form rectangle till the moment when chart drawn. This is very noticeable even if to use core i7 with 32Gb ram and video card with 1gb ram, and that effect had very bad impact on presentation charts when intensive using it.

I hope that there is some solution to avoid that behaviour. Please help to find solution.
Thank you in advance.
Alex.

GroupRenderMode="Flat" and style binding errors

I am getting binding errors in the debug log when I use GroupRenderMode="Flat" with styles that depend on the ItemsSource item values. It looks as if each row is trying to bind to the RadGridView's DataContext in addition to the actual items. The style is applying correctly, the only difference I can see is the new errors in the debug log.

Below is a small example showing the problem. Note the binding error for every line in the grid:

System.Windows.Data Error: 40 : BindingExpression path error: 'IsComplete' property not found on 'object' ''MainWindow' (Name='')'. BindingExpression:Path=IsComplete; DataItem='MainWindow' (Name=''); target element is 'GridViewRow' (Name=''); target property is 'NoTarget' (type 'Object')

which does not occur if GroupRenderMode="Nested". It's trying to bind to MainWindow object instead of an Item.

Is this a bug or have I done something wrong somewhere?

Thanks,
Louis

<telerik:RadGridView ItemsSource="{Binding Path=Items}" AutoGenerateColumns="False" GroupRenderMode="Flat">

<telerik:RadGridView.Resources>

<Style TargetType="{x:Type telerik:GridViewRow}">

<Style.Triggers>

<DataTrigger Binding="{Binding Path=IsComplete}" Value="False">

<Setter Property="Background" Value="Red"/>

</DataTrigger>

</Style.Triggers>

</Style>

</telerik:RadGridView.Resources>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="ItemName" DataMemberBinding="{Binding Path=ItemName}" Width="*" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

public class Item

{

public string ItemName { get; set; }

public bool IsComplete { get; set; }

}

public partial class MainWindow : Window

{

public ObservableCollection<Item> Items { get; set; }

public MainWindow()

{

InitializeComponent();

Items = new ObservableCollection<Item>();

for (int i = 0; i < 5; i++)

Items.Add(new Item()

{

ItemName = "Object " + i,

IsComplete = (i % 2 == 1 ? true : false)

});

DataContext = this;

}

RadDiagramConnection SourceCapType

I am using the Arrow5Filled and Arrow5 SourceCapType's to differentiate between 2 different join types in my diagram. When a user double clicks the join line I throw up a popup and allow them to enter/edit information about the join. The problem I am facing is that the Arrow5 SourceCapType is not clickable unless you get right on the line (very fiddly), opposed to the Arrow5Filled which is clickable anywhere in the shape. How can I make the Arrow5 SourceCapType to have the same behavior as the Arrow5Filled SourceCapType?

Can I Get a Hold of a WPF 3.5 build?

I understand you are not supporting WPF 3.5 officially, but if I buy a license, can I still get a hold of the latest WPF .NET 3.5 build without support? I'm in a bind here, and I know from experience that Telerik is the best thing out there. Our company can only develop with .NET 3.5 for customer deployment reasons with various clients. Currently I'm stuck modifying the plain vanilla .NET 3.5 WPFToolkit DataGrid and open source codeplex files such as TreeViewEx. Although they do the job, I don't completely trust them as much as I trust a third party tool such as Telerik, and have already run into hurdles with them that are eating up my time fixing them.

best,

-Mike Gold

Group Multiple Categories

I love the examples you have showing how you can group by a category. Is it possible to add multiple categories to an appointment and group by it? For example, lets say using your TV Schedule example, a show might be Sports and Documentary. So when Grouping, I would like to see the Appointment come up in both Sports and Documentary. Obviously, I have to be able to select multiple categories. But how to group by them as well? Would be a HUGE Help if you could give me some direction.
