I have a master detail screen using gridviews.

When a new master row is saved, the server creates detail rows, but the detail gridview does not display/retrieve these new rows until a different master row is selected and then the new master row is again selected.

How can I get the detail gridview to retrieve these new rows as soon as the save is done?

Putting detailDataSource.Refresh() after the masterDataSource.SubmitChanges() does not work.

Thanks. (This is in a MVVM system btw).

hi there,

I've got a problem in adding some Data items to RadTreeView's DataContext. Here is the code and descriptions:

in My XAML side, I've added a RadTreeView like this:


I want to add some Items when user types something in RadWatermark and presses Enter key, Thus I Write the following code:

The Sub runs successfully but right after End Sub, I got this Error in Sub Main of Application:

WHAT'S WRONG WITH ME?

Hi,
Does RadChartView has a SplineRange series implementation?
Also any new progress with implementation of series descriptor for range series? (http://feedback.telerik.com/Project/143/Feedback/Details/98763-add-series-descriptor-for-range-series)
Thanks,
Alex

hi everybody
i wanna use raddocking
but when i want use telerikQuickStart:ThemeAwareBackgroundBehavior.IsEnabled="True" i get error

i add   xmlns:telerikQuickStart="clr-namespace:Telerik.Windows.Controls.QuickStart;assembly=QuickStart.Common" but dont help me
in
some thread write
xmlns:tkqs="clr-namespace:Telerik.Windows.Controls.QuickStart;assembly=Telerik.Windows.Controls"
but this not work in my project

please see my attach file
http://uplod.ir/jj74goijoexi/WpfAtestdock.zip.htm


error:

I read some threads on it forum on this topic and I produced the following code in  xaml:

 <Grid>           
                                <telerik:XamlDataProvider x:Name="XamlDataProvider" Xaml="{Binding xxx}"
                                    RichTextBox="{Binding ElementName=RadRichTextBox}"/>
                                <telerik:RadRichTextBox x:Name="RadRichTextBox" IsSpellCheckingEnabled="False"/>
                                <!--<TextBlock Text="{Binding xxx}"></TextBlock>-->
                            </Grid>

The xxx is a property in my view model. The data from RadRichTextBox document I convert to xaml and save in database and when I open a window and in database is the xxx I want to display it in RadRichTextBox. Now it's don't work. When I uncomment the line with textblock then in it there is the xaml string so datacontex should be good.

Dear all,
I create an application using WPF (MVVM) along with Telerik UI for WPF. I got into a problem with exporting gridview to excel using GridView's export method.
Simply saying, all column headers that contain custom header show a type name instead of Header.Text:
Is there a solution for this? Maybe there is another approach since I use custom .Header section because of Business wants to have the headers wrapped and setting Wrap in GridViewComboBoxColumn seems not working.

Hi Telerik,

I have a problem getting the correct mouse coordinates(lineSeries is a RadCartesianChart). I know how to get the coordinates:

var mousePosition = e.GetPosition(lineSeries);
DataTuple tuple = lineSeries.ConvertPointToData(mousePosition);

double x = (double)tuple.FirstValue;
double y = (double)tuple.SecondValue;

But i have 3 axes on my graph and when i extract the mouse coordinates i get the coordinates for the wrong axes. They are defined like this:

<telerik:RadCartesianChart.HorizontalAxis>
<telerik:LinearAxis VerticalLocation="Bottom" Title="Concentration(µmol/L)" x:Name="HorizontalAxis"/>
</telerik:RadCartesianChart.HorizontalAxis>

<telerik:RadCartesianChart.VerticalAxis>
<telerik:LinearAxis IsInverse="True" Title="Depth(µm)" x:Name="VerticalAxis"/>
</telerik:RadCartesianChart.VerticalAxis>

Haxis = new LinearAxis();
Haxis.Title = "Rate (nmol cm-3 s-1)";
Haxis.VerticalLocation = AxisVerticalLocation.Top;
Haxis.IsInverse = true;

I get the mouse coordinates for the horizontal axis defined in XAML but i want mouse coordinates for the horizontal axis defined in the C# code.

So how would i extract mouse coordinates for the correct axes when i have more than two?

Best regards,
Jeppe

Hello,
I would like to bind entity from the itemsource collection to the command parameter.

My goal is to open certain entity when it is clicked from the grid, but have unable to bind
the entity from the binded collection.

Is this possible to do by using MVVM approach?
One challenge is that I have two telerik:BarSeries defined for the chart.

So this code line at the below needs to be sorted out,
"CommandParameter="???????????????" 

Here is the full code:


<telerik:RadCartesianChart Margin="10" IsHitTestVisible="True">

           <telerik:RadCartesianChart.Grid>
                <telerik:CartesianChartGrid MajorLinesVisibility="XY" MajorXLinesRenderMode="All">
                </telerik:CartesianChartGrid>
           </telerik:RadCartesianChart.Grid>

            <telerik:RadCartesianChart.HorizontalAxis>
                <telerik:DateTimeContinuousAxis MajorStepUnit="Minute" MajorTickStyle="{StaticResource MajorTickStyle}" PlotMode="OnTicksPadded">
                    <telerik:DateTimeContinuousAxis.TitleTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding}"></TextBlock>
                        </DataTemplate>
                    </telerik:DateTimeContinuousAxis.TitleTemplate>
                </telerik:DateTimeContinuousAxis>
            </telerik:RadCartesianChart.HorizontalAxis>
            
            <telerik:RadCartesianChart.VerticalAxis>
                <telerik:LinearAxis Minimum="0" Maximum="200" ShowLabels="False"></telerik:LinearAxis>
            </telerik:RadCartesianChart.VerticalAxis>

            <telerik:BarSeries ItemsSource="{Binding EntityData1}" ValueBinding="EntityTime" CategoryBinding="EntityTakingTime" Height="1000">
                <telerik:BarSeries.PointTemplate>
                    <DataTemplate>
                        <Rectangle x:Name="RectangleGreen" Fill="Green" MaxWidth="20"/>
                    </DataTemplate>
                </telerik:BarSeries.PointTemplate>
            </telerik:BarSeries>

            <telerik:BarSeries ItemsSource="{Binding EntityData2}" ValueBinding="EntityTime" CategoryBinding="EntityTakingTime" Height="1000">
                <telerik:BarSeries.PointTemplate>
                    <DataTemplate>
                        <Rectangle x:Name="RectangleRed" Fill="Red" MaxWidth="20"/>
                    </DataTemplate>
                </telerik:BarSeries.PointTemplate>
            </telerik:BarSeries>

           <telerik:EventToCommandBehavior.EventBindings>
                <telerik:EventBinding Command="{Binding OpenEntityCommand}" 
                                      EventName="MouseLeftButtonDown" 
                                      RaiseOnHandledEvents="True"
                                      CommandParameter="???????????????" />
            </telerik:EventToCommandBehavior.EventBindings>

</telerik:RadCartesianChart>


Check the attached screenshot to see the generated chart.
Green and red bars should work as links to open certain entity.

Best Regards, Tommi

Hi,

In my ScheduleView control, I display from monday to friday, from 8:00AM to 9:00PM. In the grid, I can have appointments, specials slot and empty cells, so, I know there is an event when an appointment selection changed but I didn't find anything for "special slot" or "empty cell" selection changed!!! Can you tell me if something exist for that?

Thank's
Alain

Hi,

I just checked your documentation about RadScheduleView and aspnet-ajax RadScheduler.
The first looks like this:
http://www.telerik.com/help/wpf/radscheduleview-populating-with-data-binding-to-db-datatier.html
And for ajax it is:
http://www.telerik.com/help/aspnet-ajax/scheduler-database-structure.html

As far as I can see the DB-Structure is different.
For Recurrence I found - for WPF
[RecurrencePattern] [varchar](100) NULL,
and for AJAX
[RecurrenceRule] nvarchar(1024) NULL,
[RecurrenceParentID] INT NULL,

My approach is to build a "schedule manager" in WPF - and an ASPX page on the intranet where everyone can view the schedules.
Does this work?
Or in other words - is there a compatible DB structure, or not?

Thanks in advance
Manfred
