Dear Telerik Support Team,
I am using version 2015.2.623.45 to replace Syncfusion components with Telerik ones.
Now is Docking turn. One of customer request is to open different tools and dock them in a Document view. Each tool (a User Control) has it’s own Ribbon that has to be merged with the one on the main window. I succeeded in my porting but to fulfil all requirements I need also to know (with an event) when a document-docked control has been selected. I did not find an event to hook that could be used.
In attachment, you can find a sample project.
Can you help me?

Thank you

Domenico

Hi,

I implemented some custom connections, deriving them from RadDiagramConnection. My connections have their own properties and visual aspect (defined using styles). I'd like to use the Telerik connection tool to draw my custom connection: how can i set the custom connection type to the connection tool?

Thank you in advance

Paolo

I have an issue with RadMaskedNumericInput where the value returned only has 1 decimal even the 2 decimals were input.

The xaml looks like this:

<telerik:RadMaskedNumericInput
    Name="AddHours"
    Width="75" 
    Mask="#,###.##"
    SelectionOnFocus="SelectAll"
    Value="{Binding AddHours}" 
    UpdateValueEvent="LostFocus"
    Culture="en-CA"
    Grid.Column="3" Grid.Row="1"
    HorizontalContentAlignment="Right"
    HorizontalAlignment="Left"
    VerticalAlignment="Top"
    Margin="3" Padding="2" 
    Style="{StaticResource HoursStyle}"        PreviewKeyDown="RadMaskedNumericInput_PreviewKeyDown"
 />

Bound Property

public decimal AddHours
{
    get { return addHours; }
    set
    {
        if (addHours != value)
        {
            addHours = value;
            OnPropertyChanged("AddHours");
 
        }
    }
}

I've tried specifying the mask differently but same behaviour with other configurations.  ???

Hey,

I have RadTreeListView named ItemsTree and i have another RadTreeListView named ChildItemsTree, the ChildItemsTree is inside the RowDetailsTemplate of ItemsTree, when the user selects an item from the ChildItemsTree i noticed that the selected item of ItemsTree does not clear. what i want to do is to clear the selected items of ItemsTree when the user selects an item from the ChildItemsTree​ and vice versa.

Thanks in advance.

 Hello,

 

I was wondering if there was any new option in the control to modify at once several cells of a GridViewComboBoxColumn, as I am using the same ItemsSourceBinding for all rows of that column (in my GridView, the selection ​is: SelectionMode="Multiple" SelectionUnit="FullRow").

I found that as a string point, but is there some other builtin/custom option than that kind:

Thanks,

Christophe

Our application is in WPF and we are using RED Timebar control for playing video.
We are facing some issue with that.

1) When we change mouse wheel we are changing time in that, as we need that event as we like to bind some other control on that. So can we know how to generate mouse wheel event?

2) As in our application we can bind multiple video control, we also have to add multiple time in same REDTimebarLine in REDTimebar control, so is there any possibility for that?

3) In the selected range of REDTimebar, we need one cursor bar that give actual time while video is running and that cursor will change inbetween selected Range only and we also need its click and drag and drop event too.

attached image provide the idea what we need using timebar control.
