Hello,
In the attached example, applying character formatting to a selection that ends between two annotation ends and undoing the formatting action does not revert the annotations to the exact position as they were before the formatting was applied.
Applying formatting twice and undoing twice crashes the editor because the second undo command inserts unpaired annotations (as it operates on a document state different than the expected one).
If the autohiding feature of the taskbar is enabled and RadWindow is maximized, the taskbar is not displayed when the mouse is over the bottom of the screen.
This is observed also in RadTabbedWindow.
Is there a workaround for this or is this a bug that you will fix?
If you set the RadNavigationView's IsPaneOpen property in XAML and start the application, the items are is not opened (the pane is collapsed). You can notice that IsPaneOpen property is set back to false, when the control gets loaded.
To work this around, subscribe to the Loaded event of the RadNavigationView instance and in the event handler, set the IsPaneOpen property.
private void RadNavigationView_Loaded(object sender, RoutedEventArgs e)
{
this.radNavigationView.IsPaneOpen = true;
}
When you have rows grouped by null value and you try to move one of the rows to another group, a NullReferenceException is thrown.
This is reproducible only when DataView is used as ItemsSource of RadGridView.
To work this around, avoid using null values. Or avoid using DataView.
If the DataSource property is set before the MessageConverter property an ArgumentException is thrown. The error message is "Item cannot be converted to MessageBase".
To work this around, make sure that the MessageConverter property is set (and evaluated) before DataSource.
Since i cannot upload zip-files in the Forum I am doing it here.
The problem is, that a single grouping dramatically increases the time for sorting the values.
When the grouping is not present, sorting the same column is much faster.
It appears that it is related to the ammount of columns in total (not grouped).
The ammount of records is not so important, 100 (as in the attached sample) should not be significant.
The check mark of the RadioButton is misaligned when DPI settings are set to a higher than the default value, e.g. 125%.
The problem can easily be reproduced using the Telerik UI for WPF Demo application:
" Collection was modified; enumeration operation may not execute.'" - The exception is observed when the CLR exceptions are enabled from Visual Studio.
Edit:
The Ellapsed event handler of the Timer is executed in background thread but modifying chart data in a background thread is considered bad practice which is not supported by our component. This is the reason we are declining this bug report.
General solution is to schedule the data update to happen on the UI thread with Dispatcher. When in ViewModel, the following code can be used:
private void OnTimerElapsed(object sender, ElapsedEventArgs e){
ViewModelBase.InvokeOnUIThread(() =>
{
for (int i = 0; i < Items.Count; i++)
{
Items[i].X += (_random.NextDouble() - 0.5) * 0.1;
Items[i].Y += (_random.NextDouble() - 0.5) * 0.1;
}
});
}
Select nested item in virtualized treeview with single selection mode.
Collapse its parent. Select item in the level of the parent. Expand the parent and notice two items are visually selected.
Expexted : only the last selected item with mouse should be visually selected.
Workaround:
private void TreeView_ItemPrepared(object sender, RadTreeViewItemPreparedEventArgs e){
if ((e.PreparedItem.IsSelected == true && this.TreeView.SelectedItem != null && this.TreeView.SelectedItem != e.PreparedItem.Item))
e.PreparedItem.IsSelected = false;
}
