Design time view of RibbonView does not synch with XAML

When designing the RibbonView using both Design and XAML views, the visual for the RibbonView switches tabs automatically and does not stay in synch with the XAML that you are working on. For example, if you have 5 RibbonTabs and are adding RibbonButtons to the second tab using XAML, the design view will switch to the last tab. So you then have to click the second tab in the Design view so that you can see the new button you just added via XAML.

Is there a fix or workaround for this?

Chartview missing in 2012 Q1

I upgraded my system from 2011 Q3 to 2012 Q1 (downloaded WPF MSI and installed, used the upgrade Wizard to upgrade my project).

The chartview control does not show in either the toolbox (forced refresh during upgrade and again using the menu option 'Launch Toolbox configurator') nor within the VS2010 Choose Toolbox Items dialog, list of WPF controls.

The chart control is listed, and it would seem everything else - just not RadChartView.
It was in the toolbox in the 2011 Q3 package.

Can you advise what DLL it is in so I can check for that on my system?

RadGridView + CommitEdit + CancelRowEdit

hi,

i'm using RadgridView to display my Databaseitems from a sqlite Database. I bind the Data like that:

DataTable dt = new DataTable();
dt = ITA_CRM.Klassen.sqlite.Verbindungen_GET();
MyradGrid.ItemsSource = dt.DefaultView;

Now i want to insert Items, Delete itmes and change items. I would like to use the "telerikGrid:RadGridViewCommands.CancelRowEdit" or
telerikGrid:RadGridViewCommands.CommitEdit"

<telerik:RadButton Width="Auto" Content="save changes" Margin="0,0,5,0" Command="telerikGrid:RadGridViewCommands.CommitEdit" CommandTarget="{Binding ElementName=VerbindungenRADGRID}" Padding="5"/>

<telerik:RadButton Width="Auto" Content="undo changes" Command="telerikGrid:RadGridViewCommands.CancelRowEdit" CommandTarget="{Binding ElementName=VerbindungenRADGRID}" Padding="5"/>

Is it the right why? Is it better to bind the Data on an other way? how? Can't find a good example to do that.

Thanks a lot
regards
ww

Live Data BarSeries Refresh

Hi,

I need to build a vertical bar chart that needs to be refreshed every second.

See attached file to check what I got until now.

The RadChart is bound to a Queue<int> that is refreshed every second.

The problem is that the BarSeries doesn’t get updated.

I manage to force it to be updated by calling RadChar.Rebind() method.

But it redraw the BarSeries instead of updating it.

Could you help me on this?
Thanks,
Hugo.

[Solved] Cell Tooltips

I'd like to display dates in the grid in a short format, and then have a hover over tooltip that displays the full date. For example, a cell might have 13/09, and the tooltip will display 13/09/2009.

Is this possible in the RadGridView?

Thanks,
Dan

MapPinPoint not displaying for zoom levels > 20

Hi,

I have an existing system using RadMap which works well. It displays a shapefile with MapPinPoints overlayed on top. One problem we had was that we couldn't zoom beyond zoomlevel 20; however I have downloaded the latest trial version which has a fix for this (setting MaxZoomLevel).

The problem is that when I now zoom beyond zoomlevel 20, all the MapPinPoints disappear but the shapefile is still rendered in the background. The shapefile is loaded using a DynamicLayer and the MapPinPoints are loaded onto an InformationLayer.

Is this a known issue or am I missing something?

Thanks,
Stuart

Issues with the GridViewComboBoxColumn

Hello,

I have an issue where I need some help. I am creating an WPF MVVM application. I have a view with in it displayed a RadGridView. One of the columns of this gridview is a GridViewComboBoxColumn. See code

    
            <telerik:RadGridView x:Name="GridView"  
        
                ItemsSource="{Binding DataContext.ObservDistributions, ElementName=DistributionView}"  
        
                AutoGenerateColumns="False"  
        
                CanUserFreezeColumns="False" 
        
                acb:CommandBehavior.Event="MouseDoubleClick"  
        
                acb:CommandBehavior.Command="{Binding SelectCurrentDistributionCommand}" 
        
                acb:CommandBehavior.CommandParameter="{Binding ElementName=GridView, Path=SelectedItem}"> 
        
                    <telerik:RadGridView.Columns> 
        
                    <telerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Name}" IsReadOnly="True" /> 
        
                    <column:DateTimePickerColumn Header="Date" DataMemberBinding="{Binding DateFrom}" Width="200"></column:DateTimePickerColumn> 
        
                    <telerik:GridViewComboBoxColumn Header="Establishment" ItemsSource="{Binding DataContext.Establishments, ElementName=DistributionView}" SelectedValueMemberPath="EstablishmentId" DisplayMemberPath="Name" DataMemberBinding="{Binding Establishment.EstablishmentId, Mode=TwoWay}"> 
        
                    </telerik:GridViewComboBoxColumn> 
        
                </telerik:RadGridView.Columns> 
        
            </telerik:RadGridView>

I have in the ViewModel a ObservableCollection named "ObservDistributions". This all works perfectly. The issue is where I change the value of the GridViewComboBoxColumn. I use MouseDoubleClick to send the changes from the View to the ViewModel. In the acb:CommandBehavior.CommandParameter I sent the item to the ViewModel with a command. This all works but not for the GridViewComboBoxColumn. The changes made to the GridViewComboBoxColumn are not sent to the ViewModel. I think the issue is with the DataMemberBinding in the GridViewComboBoxColumn. I have used the DateTimePickerColumn from Telerik, changes made with this control works fine.

Does anyone have some hint in what direction to look.

Thanx in advance

Stefan

RadRichTextBoxRibbonUI Insert Comment

I can insert a comment but when I try to type in the comment I can only type one letter and then the cursor moves back to the document area.

<telerikHTML:HtmlDataProvider Name="dp1" Html="{Binding TaskText, Mode=TwoWay}" RichTextBox="{Binding ElementName=TaskEditor}" />

<telerik:RadRichTextBox x:Name="TaskEditor" Grid.Row="1" Grid.Column="1" Margin="0,5,0,5"

_lastDataContext = _contextualTabView.DataContext;

_contextualTabView.DataContext = TaskEditor.Commands;

_lastTab = _ribbonView.SelectedTab;

_contextualGroup.IsActive = true;

}

[Solved] GetCurrentWord

I'm trying to get the word I just wrote.
I tried these methods.

private void EditorPreviewEditorKeyDown(object sender, PreviewEditorKeyEventArgs e)
{

var word = radRichTextBox.Document.CaretPosition.GetCurrentWord();
or... var word = radRichTextBox.Document.CaretPosition.GetCurrentSpanBox().Text;.

But none of them gives me the desired result.
Do they work in Wpf? What do they do? How could I get the word 'at the caret'?
Where can I read (wpf)documentation about this?
