ColorPaletteView color item spacing

<telerik:RadColorPaletteView HorizontalAlignment="Left" Width="150"

PaletteOrientation="Horizontal" PaletteColumnsCount="8"

ItemsSource="{Binding AvailableColors}"

SelectedItem="{Binding TagColor, Mode=TwoWay}"

SelectionChanged="RadColorPaletteView_SelectionChanged"

/>

Hi,

We are using the ColorPaletteView with a defined set of 13 colors in two rows. There is sufficient spacing between the columns but vertically the color items seem to not have any spacing between them.

How do I specify the spacing between the rows of color items?

LoadOnDemand changing CheckState

I have created the following RadTreeView:








<Style TargetType="telerik:RadTreeViewItem" x:Key="RadTreeViewItemStyle">
    <Setter Property="CheckState" Value="{Binding Path=CheckState, Mode=TwoWay, Converter={StaticResource ToggleStateToBoolean}}" />
    <Setter Property="DefaultImageSrc" Value="{Binding ListImage}" />
    <Setter Property="IsExpanded" Value="{Binding IsExpanded}" />
    <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}" />
</Style>
<HierarchicalDataTemplate x:Key="TreeViewItemTemplate" ItemsSource="{Binding DirectoryList}" ItemContainerStyle="{StaticResource RadTreeViewItemStyle}">
    <TextBlock Text="{Binding DisplayName}"  Margin="0,0,5,0"/>
</HierarchicalDataTemplate>
  
        <telerik:RadTreeView Grid.Column="0" IsLineEnabled="True" ItemsOptionListType="CheckList" IsOptionElementsEnabled="True" IsTriStateMode="True"
                             BorderBrush="Black" BorderThickness="1" ItemsSource="{Binding RootItems}" ItemTemplate="{StaticResource TreeViewItemTemplate}"
                             IsLoadOnDemandEnabled="True" LoadOnDemand="RadTreeView_LoadOnDemand" ItemContainerStyle="{StaticResource RadTreeViewItemStyle}"
                             Background="White" Name="ExplorerTree">
        </telerik:RadTreeView>



In the codebehind, I am passing the LoadOnDemand back to my viewmodel for processing.  Everything is working exactly as it should except for when I attempt to load a node that has been selected.  If I select the node and then fire the LoadOnDemand event, it loads properly and displays all the child nodes, but then deselects the node itself.  How can I get it to stop doing this?

Binding issue of Checkbox in Cell template

Hi All,
I am using MVVM pattern in my WPF application. I am using the Modal created by Entity Framework and my ViewModel class have public properties for binding. I have a specific requirements that my GridView should have two checkboxes columns and one TextBox column (all time in Edit mode) and all other remaining columns will be in ReadOnly mode. When user either Check/Uncheck these checkboxes OR change value in TextBox, I will have to do custom calculation on it (Note that for firing these calculation, I should have separate property in ViewModel so that I can fire in its SET clause....Am I right?)
I created the Grid in XAML like this.

<telerik:RadGridView Grid.Column="1" Grid.ColumnSpan="3" Grid.Row="0" Name="radGridView1" AutoGenerateColumns="False" ShowGroupPanel="False"

ItemsSource="{Binding IndicatorsList}">

<telerik:RadGridView.Columns>

<col:MyColumn Header="#" Width="35"/>

<telerik:GridViewColumn IsReadOnly="False" Header="Inc." Width="35">

<telerik:GridViewColumn.CellTemplate>

<DataTemplate>

<CheckBox IsChecked="{Binding IncludeIt, Mode=TwoWay}"/>

</DataTemplate>

</telerik:GridViewColumn.CellTemplate>

</telerik:GridViewColumn>

<telerik:GridViewDataColumn Header="Indicator" DataMemberBinding="{Binding DisplayName}" IsReadOnly="True" Width="250" />

<telerik:GridViewColumn IsReadOnly="False" Header="Log" Width="35">

<telerik:GridViewColumn.CellTemplate>

<DataTemplate>

<CheckBox IsChecked="{Binding LOG, Mode=TwoWay}"/>

</DataTemplate>

</telerik:GridViewColumn.CellTemplate>

</telerik:GridViewColumn>

<telerik:GridViewColumn IsReadOnly="False" Header="Lag" Width="75">

<telerik:GridViewColumn.CellTemplate>

<DataTemplate>

<TextBox Text="{Binding LAG, Mode=TwoWay}"/>

</DataTemplate>

</telerik:GridViewColumn.CellTemplate>

</telerik:GridViewColumn>

<telerik:GridViewColumn Header="Del." Width="35">

<telerik:GridViewColumn.CellTemplate>

<DataTemplate>

<telerik:RadButton Command="{Binding Delete}" CommandParameter="{Binding}" Width="27" Height="20">

<Image Source="/finStat.MacroVal.UI;component/Images/del_small.png"></Image>

</telerik:RadButton>

</DataTemplate>

</telerik:GridViewColumn.CellTemplate>

</telerik:GridViewColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

Here is my ViewModel

public List<Indicator> IndicatorsList

{

get { return Indicators.ToList(); }

}

public bool IncludeIt

{

get { /******Here How I get current object item (i.e. Indicator) of the row so that I can return its value *********/ }

set { /******Here How I get current object item (i.e. Indicator) of the row so that I set its value *********/ }

}

I am really stuck that how can I create properties for these check boxes and TextBox. Basically how can I get specific row DataItem in checkbox property so that I can return specific field from that DataItem.
Although my actual Model object is Entity Framework Model, but here is sample model for this example.

public class Indicator

{

public bool IncludeIndicator { get; set; }

public string Name { get; set; }

public bool Log { get; set; }

public double Lag { get; set; }

}

Any help please?

RadTreeListView Filters : Save and Load from a file

Hello Telerik Team,

My application has a RadTreeListView control that can be filtered by the user.

I want to save the Filter settings in a user preferences file on application shutdown and then load and apply the filters back to the RadTreeListView on application startup.

Can you help me with C# code snippets that will dump the filter settings to a text file and load them back from that file please?

I am using version 2011.1.419.35 of your WPF controls.

Thanks,
Kumar
