Questions on UI for WPF Forum

I followed the instructions in another forum post for changing the colors of my pie chart and that worked fine, but the legend colors continued to show the original theme colours.

My XAML inside the grid resources (I only set the first two colors).

    
                        <SolidColorBrush x:Key="RadialItemStroke" Color="#FF000000"/>  
        
                        <telerikStyling:StylesPalette x:Key="{telerikStyling:ThemeResourceKey   
        
                                ThemeType={x:Type telerikStyling:Office_BlackTheme},   
        
                                ElementType={x:Type telerikStyling:ChartArea},   
        
                                ResourceId={x:Static telerikStyling:ResourceHelper.ResourceKeyRadialStyle}}"> 
        
                            <Style TargetType="{x:Type Shape}">  
        
                                <Setter Property="Stroke" Value="{StaticResource RadialItemStroke}" /> 
        
                                <Setter Property="StrokeThickness" Value="2" /> 
        
                                <Setter Property="Fill" Value="{StaticResource WidgetLightGreen}" /> 
        
                            </Style> 
        
                            <Style TargetType="{x:Type Shape}">  
        
                                <Setter Property="Stroke" Value="{StaticResource RadialItemStroke}" /> 
        
                                <Setter Property="StrokeThickness" Value="2" /> 
        
                                <Setter Property="Fill" Value="{StaticResource WidgetOrange}" /> 
        
                            </Style> 
        
                        </telerikStyling:StylesPalette>

My chart.

    
                        <telerik:RadChart x:Name="ProgressChart"   
        
                                          Margin="4,8,4,4" 
        
                                          VerticalAlignment="Stretch"   
        
                                          HorizontalAlignment="Stretch">  
        
                            <telerik:RadChart.Background> 
        
                                <SolidColorBrush Color="Transparent"/>  
        
                            </telerik:RadChart.Background> 
        
                        </telerik:RadChart>

Nothing fancy, but the legend doesn't color correctly. I saw another post that mentionned the data series naming & legend items naming have been decoupled in the latest release - so I am assuming that also the colors were seperated as well, but I can't figure out how to change them.

RadTreeView.Scroll doesn't fire with mouse wheel

I have this event handler:

                             
                     
                    private void theTree_SelectionChanged(object sender, System.Windows.Controls.SelectionChangedEventArgs e)         
                    {         
                        // do something         
                    }         

And it fires all right when I move the scroll bar by dragging it, but when I move around with the mouse wheel, it doesn't fire. Any workaround for this?

Thanks!

Always fill RadDock

I'm in the process of testing out the telerik rad controls for WPF and trying to decide if these controls best fit my needs.
Currently I'm testing the RadDocking and what I'm looking to accomplish is, have any panel I put in have the ability to fill the container and then the next panel would split depending on where I dock it.

Example:
If I have two floating panels and if I drag and dock the first left, it will dock left and fill the whole RadDock, then if I take the second panel and dock bottom, it will split the first panel and appear to be on the bottom. then I'll continue to dock like this until the interface is built(with additional panels.
Also I'd like to not have any DocumentPanes, I don't want to see tabs unless I fill one panel inside another.

Hopefully this makes sensem I'd appreciate any example someone can provide to accomplish this.

thanks steve

IDataErrorInfo problems

It seems like there are a 2 problems if you try to validate your data by using IDataErrorInfo.

- The UI doesn't get updated properly. I set the background to red for a test and added a breakpoint at the validation part of the code. The code gets validated properly but the background stays red once the error is resolved.
- If you enter a wrong value the text gets moved to the top left corner of the cell and you aren't able to edit the cell until you press escape.

Setting TickLineStyle makes ticks disappear completely

Hi Telerik,

When I set tick line styles as follows:

    
            <Style x:Key="AxisTickStyle" TargetType="Line">  
        
                    <Setter Property="Stroke">  
        
                        <Setter.Value> 
        
                            <SolidColorBrush Color="{DynamicResource ColorDarkGray}" />               
        
                        </Setter.Value>           
        
                    </Setter> 
        
                </Style>

    
            chart.DefaultView.ChartArea.AxisX.AxisStyles.TickLineStyle = Application.Current.Resources["AxisTickStyle"] as Style;  
        
            chart.DefaultView.ChartArea.AxisX.AxisStyles.MinorTickLineStyle = Application.Current.Resources["AxisTickStyle"] as Style;

They dissappear completely, looks like the actually width of them decreases to 0 because the ItemLabels come to the edge of the axis

Any help would be appreciated

WPFWindow ShowDialog not working the second time?

Hi,

We've got the following code in the application's App class's constructor (the fact that we're doing this in the App class appears to be related to the issue):

                                bool allGood = false;         
                        do         
                        {         
                            LoginWindow loginWindow = new LoginWindow();         
                            loginWindow.ShowDialog();         
                                     
                            if (loginWindow.DialogResult.GetValueOrDefault(false))         
                            {         
                                try         
                                {         
                                    // Try and do something...         
                                    allGood = true;         
                                }         
                                catch (Exception)         
                                {         
                                    lastLoginFailed = true;         
                                }         
                            }         
                            else         
                                return;         
                        } while (!allGood);         

In the LoginWindow, there's a button whose Click handler ends with a call to Close(). The "Try and do something" code tries something that may possibly throw an Exception. If it does, then allGood stays false and the loop happens again. If it doesn't throw an exception, allGood is set to true and the job ends.

The problem is this - the first call to ShowDialog works fine. The second call does nothing.

Any idea what we're doing wrong here?

Thanks,

yonadav

Set the size of Bar series gap

My chart has 3 Bar series, the 3 bars are shown next to each other and there's a gap between it and the next group of 3 bars. Is there a way to set the size of this gap? In my case I need it to be 0 (no gap).
