Hi,

Please tell me the way to override the custom color and appearance of the CarouselScrollButton. I tried the following code and it didn't have any effect on button.

<br> <telerik:CarouselScrollButton Margin="2" CarouselScrollButtonType="LineLeft" Grid.Column="1" Height="40" Width="40" Command="{x:Static ScrollBar.LineLeftCommand}" Style="{StaticResource CarouselScrollButtonStyle}" ><br> <telerik:CarouselScrollButton.Foreground><br> <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0"><br> <GradientStop Color="#FFD0F262" Offset="0.004"/><br> <GradientStop Color="#FFDEEC58" Offset="1"/><br> </LinearGradientBrush><br> </telerik:CarouselScrollButton.Foreground><br> </telerik:CarouselScrollButton>

Please tell me what am i doing wrong.

Regards,
Raj.

MouseDoubleClick on Item

Hello,

I have problem using the event "MouseDoubleClick" on RadTreeViewItem.
It is handled for each branch item and it don't care about e.Handled = true.

Example :

    
                    <telerik:RadTreeView IsDragDropEnabled="True" MouseDoubleClick="treeView_MouseDoubleClick">  
        
                        <telerik:RadTreeView.ItemContainerStyle> 
        
                            <Style TargetType="{x:Type telerik:RadTreeViewItem}">  
        
                                <Setter Property="HorizontalContentAlignment" Value="Stretch"/>  
        
                                <Setter Property="IsExpanded" Value="True"/>  
        
                                <EventSetter Event="MouseDoubleClick" Handler="treeViewItem_MouseDoubleClick"/>  
        
                            </Style> 
        
                        </telerik:RadTreeView.ItemContainerStyle> 
        
                        <telerik:RadTreeView.ItemTemplate> 
        
                            <HierarchicalDataTemplate ItemsSource="{Binding Children}">  
        
                                <Border BorderThickness="1" BorderBrush="LightGray" Margin="2" CornerRadius="5">  
        
                                    <Grid>

                                    </Grid> 
        
                                </Border> 
        
                            </HierarchicalDataTemplate> 
        
                        </telerik:RadTreeView.ItemTemplate> 
        
                        <telerik:RadTreeView.Items> 
        
                            <local:PairText Key="line1" Text="Some text for line1"/>

                            <local:PairText Key="line3" Text="Some text for line3">  
        
                                <local:PairText.Children>

                                    <local:PairText Key="line3.2" Text="Some text for line3.2"/>  
        
                                    <local:PairText Key="line3.3" Text="Some text for line3.3"/>  
        
                                </local:PairText.Children>

                            <local:PairText Key="line4" Text="Some text for line4"/>  
        
                            <local:PairText Key="line5" Text="Some text for line5"/>  
        
                        </telerik:RadTreeView.Items> 
        
                    </telerik:RadTreeView>

    
                    private void treeView_MouseDoubleClick(object sender, MouseButtonEventArgs e)  
        
                    {  
        
                        MessageBox.Show("Tree");  
        
                        e.Handled = true;  
        
                    }  
        
                    private void treeViewItem_MouseDoubleClick(object sender, MouseButtonEventArgs e)  
        
                    {  
        
                        PairText pair = (sender as RadTreeViewItem).Item as PairText;  
        
                        MessageBox.Show("Item : " + pair.Key);  
        
                        e.Handled = true;  
        
                    }

When I double click on "line3.2" I want to obtain only the "Item : line3.2" message but there is "Item : line3" and "Tree" messages too.

Have you any suggestions ?

Thanks,
Guillaume R.

Modal Load Screen - Doesn't go away

Sometimes when refreshing my grid I'm getting a modal overlay (transparent navy blue in color) with a indeterminate load circle on it.

The data still updates under the modal.. but the modal does not go away.. this behavior is reproducible.. but seems to be specific to certain data I'm changing in my grid.

Any ideas?

Clipboard is empty when application has been closed

Hi everybody,

if I copy data of the RadGridView into the clipboard I can paste it into an Excel sheet only as long as the source application (e.g. the demo application but also my own application) is running. Is there a way to keep the data in the clipboard after closing the application?

Regards Uli

Speed in a Grid.

I put this control on a grid and it dramatically reduces the rendering speed of the grid. It takes noticeably longer to scroll down.

Am I doing something wrong?

Here is what I have added to the Grid.

<telerik:GridViewDataColumn DataMemberBinding="{Binding Path=Rating}" Header="Rating" MinWidth="60" Width="SizeToCells">

<telerik:GridViewColumn.CellTemplate>

<DataTemplate>

<telerikInput:RadRating Name="_leadRating" Value="{Binding Path=Rating,Mode=TwoWay}" UseLayoutRounding="True">

<i:Interaction.Triggers>

<i:EventTrigger EventName="ValueChanged">

<cmd:EventToCommand Command=

"{Binding Path=DataContext.ChangeRatingCommand, RelativeSource={RelativeSource FindAncestor, AncestorType=UserControl, AncestorLevel=1}}"

CommandParameter="{Binding}" />

</i:EventTrigger>

</i:Interaction.Triggers>

</telerikInput:RadRating>

</DataTemplate>

</telerik:GridViewColumn.CellTemplate>

</telerik:GridViewDataColumn>

Wrap text in a legend

Hi,

I have set up constant areas : a width of 200 for the chart area and a width of 100 for the legend area.

The problem is when a label of the legend is too long for the defined width, the label is cut.

So, how could I wrap text labels of the legend of a chart ?

Thanks.

Setting Grid Scroll Position

Hello, let's start with a little background on our app.

We use RadDocking with a RadGridView in one of the panes. The problem we have is the scroll position is getting reset to the top row when the pane containing the grid is pinned or unpinned (It seems to re-get the bound ItemsSource each time the grid is loaded and unloaded causing the grid to refresh). To try getting around this issue I tried getting and setting the scrollbar's value when the grid is loaded / unloaded. However, when I set the scrollbar's value, I am unable to physically move the scrollbar. I can however see the items changing as if it was scrolling properly, just the bar doesn't move. I am using the latest 9/24/2010 release.

I added a simple WPF ScrollBar control and I can set the value and still scroll the control properly.

Is this an issue with the ScrollBar the grid is using?

If there is any other recommendations on how to keep the scroll position, I am open to that as well.

Here is some quick code showing how I am doing this.

private void Window_Loaded(object sender, RoutedEventArgs e)

{

// Get GridView ScrollBar object

ScrollBar verticalScrollBar = this.RadGridView1.ChildrenOfType<ScrollBar>().Where(s => s.Orientation == Orientation.Vertical).First();

// Set value on GridView - Goes to bottom, but cannot get scrollbar to move

verticalScrollBar.Value = verticalScrollBar.Maximum;

// Set value on WPF ScrollBar - Goes to bottom, and scrollbar moves fine

this.WpfBar1.Value = this.WpfBar1.Maximum;

}

Thanks All for your help.

Textbox Cell Style

Hello,
I am trying to set the style of my GridViewDataColumn to a textbox and am having some difficulty.
This is the latest thing I have tried. It seems that i should not be having this much trouble.
I have seen examples of checkboxes and images but cannot find a RadMaskedTextBox example. Could you provide one?

Thank you.
                        <telerikPres:RadGridView ItemsSource="{Binding}>
