Hi,

Previously I was using RadGridView with RadDataForm.
When IsSynchronizedWithCurrentItem property setted to True value, this controls working synchronous.

I needed Hierarchical items on some modules and I solved this problem with RadGridView.
But hierarchical data very complex for last user on RadGridView, that's not user-friendly.

I decided on the RadTreeListView after that, and I solved this with hierarchical TreeListView.
But there's a problem, IsSynchronizedWithCurrentItem setted True but RadTreeListView with RadDataForm not working synchronous.

How can solve this problem?

<telerik:RadTreeListView x:Name="mRadTreeListView"
                     IsReadOnly="True"
                     AutoExpandItems="True"
                     AutoGenerateColumns="False"
                     CanUserFreezeColumns="False"
                     ItemsSource="{Binding Items}"
                     IsSynchronizedWithCurrentItem="True"
                     RowIndicatorVisibility="Collapsed"
                     RowDetailsVisibilityMode="Collapsed">
    <telerik:RadTreeListView.ChildTableDefinitions>
        <telerik:TreeListViewTableDefinition ItemsSource="{Binding Children}" />
    </telerik:RadTreeListView.ChildTableDefinitions>
</telerik:RadTreeListView>
<telerik:RadDataForm x:Name="mRadDataForm"
                     ItemsSource="{Binding Items}"
                     VerticalAlignment="Top"
                     LabelPosition="Above"
                     AutoGenerateFields="False"
                     CommandButtonsVisibility="All"
                     AutoCommit="True">
</telerik:RadDataForm>

I am trying to implement one of the screen in my project using RadWindow, and I wanted to do it as a singleton within the entire application.  This RadWindow will be shown as modal from time to time.   I know that using wpf windows, doing this will give you an invalidoperationexception:

win.ShowDialog();
win.Close();
win.ShowDialog();


I see that RadWindow is not derived from Window, so my question is, is it safe for me to do show or reopen the RadWindow even after it has been closed?

I'm using RadDataForm for the first time and to mr it seems there's an uncommon behavior. I've bound MyRadDataForm.ItemsSource to a property called 'UserList' which is of type 'ObservableCollection<UserViewModel>'. When I load users from database and add them to the ObservableCollection, then UI/RadDataForm gets updated via INotifiyPropertyChanged.

Now I want to refresh the displayed data so I clear the collection (UserList.Clear()), get the users from database again and then re-add those users to the collection (UserList.AddRange(usersFromDatabase). The problem is my UI doesn't get updated anymore. It seems that RadDataForm is only updating one time.

Hi,

Extra X and Y axis lines shows up on RadChart. For fixing this issue we need to write extra code to remove these extra lines.
Please refer document attached for more details.



To solve this issue we need to remove that extra line in code for X axis and Y axis separately.
(Code Snippet Below)

private void
HideUnusedAdditionalAxis()

        {

            FrameworkElement lastAxisObject =
null;

            FrameworkElement
notZeroItemAxisObject = null;

            var axisX2DObjects =
RelationshipSummaryDepositMonthlyBalanceChart.ChildrenOfType<AxisX2D>();

 

            foreach (var axisX2D in
axisX2DObjects)

            {

                axisX2D.Visibility =
System.Windows.Visibility.Hidden;

                lastAxisObject = axisX2D;

                if (axisX2D.Items.Count != 0)

                {

                    notZeroItemAxisObject =
axisX2D;

                }

            }

            if (lastAxisObject != null)

                (notZeroItemAxisObject ??
lastAxisObject).Visibility = System.Windows.Visibility.Visible;

        }

I'm trying to follow the tutorial here. http://www.telerik.com/help/wpf/radtreeview-styling-and-appearance-styling-radtreeviewitem.html

However, when I did the same thing, I couldn't find the option for editing a copy of the default style. The only option I had is creating an empty one which doesn't include anything thing. I also tried ItemContainerStyle, no luck also.




Did I miss anything?

Hi,

I have a simple text box where I would like to use a SpellChecker for norwegian language.
Can you give me any guidelines how I can do that?

Thanks

I've just updated to the latest version of the WPF controls, and the little drop down button is not working on the document host in a docking window. The button highlights and clicks, but there's no drop down menu. This used to work, so I'm assuming some default property has been altered - or there's a bug?

I want the value with the formatting characters. I was under the impression that I could bind to the Text property of the RadMaskedTextInput to do just that. However, the data binding doesn't work. It works fine if I bind to the Value property, but I don't get the formatting characters I want.

Hi. Please help to find solution. I tried to use following sample application attached here in thread below.
http://www.telerik.com/forums/y-axis-values-on-radcartesianchart-with-zoom
Here I see same issue which I can't resolve in mine application.

To reproduce it please do following:
1. Open sample app.
2. Select with mouse some part of chart, then release mouse.
Now notice values on that Y-axis are changed, but chart line not fit region from top to bottom. There is lot of space to top or bottom, depends on which initial area was selected.
3. Now touch scrollbar and move it a bit. You see that now chart line fit region completely.

Question here. Is there any way to force chart redraw asap after zoomed with mouse, so chart line will fit new Y-axis.

Thanks in advance.

I am attempting to use  RadPanelBar as accordion panel, where all the items are independently expanded or collapsed.
When I do the data binding though, all the controls are appearing in the header.
After looking around, I understand that I need to use a hierarchical data template. I would greatly appreciate any pointers or sample code in achieving this.
