Hi!

I can set different color for each label with CreateItemStyleDelegate, could I do the same for the color of point marks of a line series?

I would specify the color of each point mark with databinding as I bind the point to it's value.

CommitEdit problem

HI,
I use in my application a gridview with four buttons to delete and add a row and to save or cancel the edit. The delete and add buttons work perfectly but not the save insert/edit button. I don't understand where is the problem in my code, if someone could help.
This is my xaml :

<Grid Name="indicatorPage" Visibility="Hidden" Margin="0,194,0,-194">

<Grid.RowDefinitions>

<RowDefinition Height="Auto" />

<RowDefinition />

</Grid.RowDefinitions>

<StackPanel Orientation="Horizontal"

HorizontalAlignment="Center"

Margin="0,5,0,0">

<telerik:RadButton Width="150"

Content="Delete selected rows"

Margin="0,0,5,0"

Command="telerikGrid:RadGridViewCommands.Delete"

CommandTarget="{Binding ElementName=gvIndicatorConf}" />

<telerik:RadButton Width="150"

Content="Add new row"

Margin="0,0,5,0"

Command="telerikGrid:RadGridViewCommands.BeginInsert"

CommandTarget="{Binding ElementName=gvIndicatorConf}" />

<telerik:RadButton Width="150"

Content="Save insert/edit"

Margin="0,0,5,0"

Command="telerikGrid:RadGridViewCommands.CommitEdit"

CommandTarget="{Binding ElementName=gvIndicatorConf}" />

<telerik:RadButton Width="150"

Content="Cancel insert/edit"

Command="telerikGrid:RadGridViewCommands.CancelRowEdit"

CommandTarget="{Binding ElementName=gvIndicatorConf}" />

</StackPanel>

<telerik:RadGridView x:Name="gvIndicatorConf"

ItemsSource="{Binding IndicatorConf}"

AddingNewDataItem="radGridView_AddingNewDataItem"

Margin="0,5,0,0" Grid.Row="1"

AutoGenerateColumns="False" telerik:StyleManager.Theme="Windows8"

MaxHeight="7000" MaxWidth="1000">

<telerik:RadGridView.Columns>

<telerik:GridViewColumn Width="90">

<telerik:GridViewColumn.CellTemplate>

<DataTemplate>

<telerik:RadButton Content="Delete"

Command="telerikGrid:RadGridViewCommands.Delete"

CommandParameter="{Binding}" />

</DataTemplate>

</telerik:GridViewColumn.CellTemplate>

</telerik:GridViewColumn>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Code}" Header="Code" UniqueName="Code" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding Descritpion}" Header="Descritpion" UniqueName="Descritpion" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding Connecter}" Header="Connecter" UniqueName="Connecter" IsReadOnly="True"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Period}" Header="Period" UniqueName="Period" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</Grid

Filtering using FilterDescriptor opens All the Nodes

I have a problem where after applying the Filter, it opens up all the nodes.

I am using FilterDescriptor.

We have a Huge Tree and we don't want the Tree and its children to open after applying the Filter. Any idea how to stop it from opening after applying the Filter?

I am not able to attach the project, but will attach the screen shot.

Here is code snippet.

private void RadContextMenu_ItemClick(object sender, Telerik.Windows.RadRoutedEventArgs e)

{

if ((e.OriginalSource as RadMenuItem).Header.Equals("Show Spain"))

{

FilterDescriptor descriptor = new FilterDescriptor();

descriptor.Member = "Country";

descriptor.Operator = FilterOperator.IsEqualTo;

descriptor.Value = "Spain";

this.RadTreeListView1.FilterDescriptors.Add(descriptor);

}

CompositeFilterDescriptor mainFilter = new CompositeFilterDescriptor();

if ((e.OriginalSource as RadMenuItem).Header.Equals("Show England"))

{

FilterDescriptor descriptor = new FilterDescriptor();

descriptor.Member = "Country";

descriptor.Operator = FilterOperator.IsEqualTo;

descriptor.Value = "England";

mainFilter.FilterDescriptors.Add(descriptor);

this.RadTreeListView1.FilterDescriptors.Add(mainFilter);

}

if ((e.OriginalSource as RadMenuItem).Header.Equals("Show England - France"))

{

mainFilter = new CompositeFilterDescriptor();

mainFilter.LogicalOperator = FilterCompositionLogicalOperator.Or;

FilterDescriptor descriptor = new FilterDescriptor();

descriptor.Member = "Country";

descriptor.Operator = FilterOperator.IsEqualTo;

descriptor.Value = "England";

mainFilter.FilterDescriptors.Add(descriptor);

descriptor = new FilterDescriptor();

descriptor.Member = "Country";

descriptor.Operator = FilterOperator.IsEqualTo;

descriptor.Value = "France";

mainFilter.FilterDescriptors.Add(descriptor);

this.RadTreeListView1.FilterDescriptors.Add(mainFilter);

}

if ((e.OriginalSource as RadMenuItem).Header.Equals("Clear Filter"))

{

this.RadTreeListView1.FilterDescriptors.RemoveAt(0);

}

Problem with CellEditTemplate

Hello!

Since I updated to 2010 Q1 my CellEditTemplate stopped working. I get an System.InvalidCastException when leaving the textbox.

    
             <telerikGrid:RadGridView  x:Name="ARVolymGridView" AutoGenerateColumns="False" ShowGroupPanel="False" ItemsSource="{Binding ARVolymer, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}" > 
        
                        <telerikGrid:RadGridView.Columns> 
        
                            <telerikGrid:GridViewDataColumn DataMemberBinding="{Binding Sortiment, UpdateSourceTrigger=PropertyChanged}" Header="Sortiment"/> 
        
                            <telerikGrid:GridViewDataColumn DataMemberBinding="{Binding Volym, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Header="M3f" > 
        
                                <telerikGrid:GridViewDataColumn.CellEditTemplate> 
        
                                    <DataTemplate> 
        
                                        <TextBox Text="{Binding Volym, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"/> 
        
                                    </DataTemplate> 
        
                                </telerikGrid:GridViewDataColumn.CellEditTemplate> 
        
                            </telerikGrid:GridViewDataColumn> 
        
                        </telerikGrid:RadGridView.Columns> 
        
                    </telerikGrid:RadGridView>

My binding properties:

    
                    public string Sortiment 
        
                    { 
        
                        get { return _arVolym.Sortiment; } 
        
                        set 
        
                        { 
        
                            if (_arVolym.Sortiment != value) 
        
                            { 
        
                                _arVolym.Sortiment = value; 
        
                                OnPropertyChanged("Sortiment"); 
        
                            } 
        
                        } 
        
                    } 
        
                    public int Volym 
        
                    { 
        
                        get { return _arVolym.Volym; } 
        
                        set 
        
                        { 
        
                            if (_arVolym.Volym != value) 
        
                            { 
        
                                _arVolym.Volym = value; 
        
                                OnPropertyChanged("Volym"); 
        
                            } 
        
                        } 
        
                    }

In my application I have an custom designed TextBox to prevent the user to enter invalid values, but the same exception appears for a regular Textbox.

This is extremly annoying that something stopped working when updating to a new and improved (?!) version.

Can Treemap render the boxes using logarithmic values?

I wonder if there is a way (other than feeding Log(x)) to render TreeMap charts to use logarithmic values?

I can feed the log(x) as the value but tooltips would not be equal even I'd convert the value using exp(x).

Versioning

I updated to the latest release of telerik controls using the control panel. I now have XAML error messages saying that there is a conflict between the Telerik versions that the project references and a referenced project references. Picture of error message attached. Do you have a suggestion as to how I can clean this up?

Both projects reference the same version of telerik controls.

[Solved] Splitter bars between RadPaneGroups within Widnows8 theme

I've applied Windows8 theme as the following code, and found splitter bars disappear between RadPaneGroups docked in the left position as shown in the attached image.
This happens only when applying Windows8 theme in code-behind.
I'm building a custom theme based on Windows8 theme, so I need this to be fixed! Can this be fixed?

public partial class MainWindow : RadRibbonWindow
{

        static MainWindow()
        {
            RadRibbonWindow.IsWindowsThemeEnabled = false;
        }

        public MainWindow()
        {
            StyleManager.ApplicationTheme = new Windows8Theme();

this.InitializeComponent();
