I'd like to react when a user changes the carret postion to a new cell inside a table.

I have tried hooking up to the Document.CaretPosition.PositionChanged event. But the event doesn't seem to fire as expected. It only fires once, when the RadRichTextBox in instantiated.

Any suggestion as to how handle this?

I want to extend date time picker control and instead of plain text box i want to use telerik masked date time input control in that.  Kindly suggest how can i update the default template for the date time picker control to replace textbox 

"By default the Virtualization feature of the RadDiagram is enabled. "

however, examples in SDK samples are UI virtualization is ineffectual.
Can I obtain a sample program that virtualization feature is correctly?

I am using 2013 q3 of the radgridview, and I need to validate my object in the row validating and cell validating event because some properties are required field.  In the row validating event, I'm explicitly clearing all the validationResults and appending 1 or more new validationresults to certain properties.  However, I found that Cell.Errors are not cleared when I clear validationResults, instead they are appeneded everytime I add a new validationresult in the row validating event.  How do I clear individual cell errors?


//rowvalidating event
if(conditionNotValid)
{
var r = param as Telerik.Windows.Controls.GridViewRowValidatingEventArgs;
r.IsValid = false;
r.ValidationResults.Clear();


foreach (.Infrastructure.ValidationError error in errors)
{
              r.ValidationResults.Add(new GridViewCellValidationResult() { ErrorMessage = error.ErrorMessage, PropertyName = error.PropertyName });
}

return;
}


//////////////////////
//Cell validating event
////////////////////// 
var c = param as Telerik.Windows.Controls.GridViewCellValidatingEventArgs;
c.Cell.Errors // errors does  not get cleared, but gets appended to this list !!!!!!!!!!

HI.

In the following example, I use a RadComboBox with TextSearchMode="Startswith".

<telerik:RadComboBox  
                        ItemsSource="{Binding RelativeSource={RelativeSource FindAncestor,  AncestorType={x:Type UserControl}},Path=DataContext.Sagsbehandler}" 
                        SelectedValue="{Binding SagsbehandlerId, ValidatesOnDataErrors=True, UpdateSourceTrigger=LostFocus}" 
                        SelectedValuePath="SagsbehandlerId"
                        DisplayMemberPath="Navn"                    
                        IsEditable="True"
                        TextSearchMode="StartsWith"
                        >
When typing the first letters of an item in the itemssource, the first match is selected/autocompleted in the editable area.

However: If I change TextSearchMode to "Contains", there is no autocompletion as I initially would have expected. Only the typed text is shown and the user has no clue if the typed text has any match in the itemssource.
How can I change this behaviour? That is, how can I enable autocompletion when using a contains search.

I am using a horizontally sliced TreeMap. Is it possible to control the VERTICAL distance (Y-Direction)?  I understand the horizontal distance is determined by the values (X-Direction).  

Ideally, the space would be equidistant vertically with all 3 groups having the same vertical distance.  Similar to a Grid with 3 RowDefinitions where Height="*"

Current XAML:

StaticResource IcicleStyle:



A screenshot of the current layout is attached.  If you look at the last section labelled "S", Ideally,  (S.Height === %G1.Height).  Even if I remove the third level of data {1,2,3,4}, the result is the same.

Any help is appreciated.

Thanks,
Jacob

HI,

I'm trying to use your Diagram control which is very cool by the way. But i'm struggling to understand how the structure works inside. Can I ask if you can compose one fully working example of OrgChart diagram like in demo. So I can study it.

Thanks in advance

Hi,
I am facing an Issue with binding in RadGrid. Here is my XAML

 <telerik:GridViewDataColumn Width="Auto" DataMemberBinding="{Binding IsTermChange}"  Header="Change Term" x:Name="TermChange">
                    <telerik:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <CheckBox IsChecked="{Binding IsTermChanged, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"/>
                        </DataTemplate>
                    </telerik:GridViewDataColumn.CellTemplate>
                </telerik:GridViewDataColumn>
                <telerik:GridViewDataColumn Width="Auto" DataMemberBinding="{Binding IsActive}"  Header="Change Mileage">
                    <telerik:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <CheckBox IsChecked="{Binding IsActive, Mode=TwoWay}"/>
                        </DataTemplate>

                                <CheckBox Name="optionCheckBox"/>
                            </Grid>
                        </DataTemplate>

                        </DataTemplate>
                    </telerik:GridViewDataColumn.CellTemplate>
                </telerik:GridViewDataColumn>
                <telerik:GridViewColumn Header="Proposed Term" >
                    <telerik:GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <telerik:RadComboBox Width="80" HorizontalAlignment="Left" Margin="3,1,0,0" Text="{Binding Path=TermRequested, Mode=TwoWay,   UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True, NotifyOnValidationError=True}" IsEditable="True" ItemsSource="{Binding AvailableTermsList}" StaysOpenOnEdit="True" />
                        </DataTemplate>
                    </telerik:GridViewColumn.CellTemplate>
                </telerik:GridViewColumn>

I want to bind the IsEnabled property of radcombobox (bold one) only when IsChecked property is true for checkbox(bold one). I am not abble to achieve that. Please help it is urgent.

I am fairly new to WPF and have not mastered MVVm so I'm building my treeview manually like so:


The image file for the state does not load despite it being in the relative path in the project.  Does it ned to be loaded in as a resource somehow rather than just specifying the relative path? 

Also what is the format of the path when bringing a TreeViewItem into view (auto scrolling) in a non-bound scenario like this, when there is more than one level involved?  I thought I saw somewhere to separate the levels items with a " | " but it doesn't seem to work.

as in:


Thanks,
