Hi,

I have multiple Radpanes in a Window, but I want to change the header of only one RadPane. How do I do it?

I can only see this

<Style TargetType="dock:PaneHeader" BasedOn="{StaticResource PaneHeaderStyle}">

But this then modifies all my pane. So could you please give me another solution?

Thanks

Hi, I use RadCartesianChart to display some candles, but I see only part of them on the screen (see picture). Seems that auto-scale works not well. How to show all candles?

Here is the code:

Hi Telerik,

I have two Control Panel Items set in a single style for all my grids. The column chooser icon that comes out of the box looks fine. but I can't find where I can change the other one. Where can I learn more about how those icons are defined? I would like some sort of an arrow pointing down.

Here is the code for the ControlPanelItemCollection

By the way, I dont get what is all this "Data". I just left it there from one of your samples, if you might as well please clarify this for me?

Thank you

How to set the max length of a PropertyDefinition  

Like the textbox' s maxlength property

Hi,

Is there an example anywhere of a user being able to click on a chart and auto-create a text annotation based on a double-click or a right-click?
They would need to be able to add multiple annotations.
They would need to be able to delete annotations (i.e. right click on the annotation itself to delete).

We need the ability for users to create their own annotations directly within the chart area..

Thanks,

Barry

Hi,

Is there an example anywhere of a user being able to click on a chart and auto-create a line annotation based on when the mouse button went down and where it went back up again after the mouse was dragged ?

This seems tantamount to drawing a straight line and then adding a label to it.

They would need to be able to add multiple lines.

They would need to be able to delete lines.

We need the ability for users to create their own annotations directly within the chart area, using their mouse.

Thanks,

Barry

In response to a button command my VM inserts a record at index 0 into  the observablecollection that is bound to the gridview.

Now that I have it in the collection a new row automagically appears in the radgrid at the beginning. I'm trying to be a good boy and keep knowledge of my UI out of the VM. My gridview is marked as IsReadOnly = true. I only  allow editing via raddataform attached to the rowdetails. My questions are:

1. How to automatically expand the row details of a newly inserted row (using MVVM)?

2. Once they hit update the newly added row seems to be moved by the gridview to it's rightful place in the sort order. This is great.However, if you are using datapager the row could be moved to an unknown page leaving the user wondering where their new record went. I know there is a ScrollIntoView function, but I'm not sure I should be using that in a VM. Even if I did, how would I know what row to scroll to after it's been resorted? So, how can I get a newly added, newly sorted row to scroll to be the first row visible regardless of which page in the pager it lands and have it's rowdetail editor expanded using MVVM?

Any help would be greatly appreciated.

Thanks ... Ed

Hello!

- Setting Telerik.Windows.Controls.MultidayViewDefinition.MinorTickLength to Zero causes a ContextSwitchDeadlock during debugging and freezes the application when having the respective ViewDefinition active or on switching to the particular ViewDefinition.

- Setting Telerik.Windows.Controls.MultidayViewDefinition.MajorTickLength or Telerik.Windows.Controls.TimelineViewDefinition.GroupTickLength to Zero both cause a System.OutOfMemoryException when having the respective ViewDefinition active or on switching to the particular ViewDefinition.

- In XAML, when setting the MinorTickLength="0min" of the first and currently in the Designer active ViewDefinition will cause Visual Studio to freeze up entirely and needs to be terminated via the TaskManager.

- In XAML, when setting the MajorTickLength="0min" or GroupTickLength="0min" of the first and currently in the Designer active ViewDefinition will render Visual Studio unresponsive for a few seconds until displaying that a System.OutOfMemoryException has occurred.

Here's my example code to reproduce the crashes and freezes:

In my opinion it would be helpful to immediately throw a System.ArgumentOutOfRangeException when setting an invalid (or even better when creating an invalid instance of) Telerik.Windows.Controls.ScheduleView.ITickProvider.

What do you think?

Best wishes!

I saw there was a post about this several years back, but the OP never followed up..

I am getting the " System.Windows.Media.Animation Warning: 6 : Unable to perform action because the specified Storyboard was never applied to this object for interactive control.; Action='Stop'; Storyboard='System.Windows.Media.Animation.Storyboard'; Storyboard.HashCode='11303829'; Storyboard.Type='System.Windows.Media.Animation.Storyboard'; TargetElement='System.Windows.Media.Animation.Storyboard'; TargetElement.HashCode='11303829'; TargetElement.Type='System.Windows.Media.Animation.Storyboard' "

I have tried everything I can think of (hopefully not missing something small and silly..).  

Here is the storyboard itself in the UserCont

Here is the 'grid' section that utilizes the storyboard.

MyTeamHasTasks is a boolean in my ViewModel.

First EventTrigger Expanded: ControlStoryboardAction: Stop  - Throws System.Windows.Media.Animation Warning: 6.

Second EventTrigger Collapsed: ControlStoryboardAction: Play - Works fine.

If I expand the TaskPanel again (firing the first eventtrigger from above) everything works as it should at this point and on..

BUT the VERY first time the ControlStoryboardAction: Stop is executed, it gives the System.Windows.Media.Animation Warning: 6.

For testing purposes, I replaced the binding boolean field (MyTeamHasTasks) with a checkbox and then bound the checkbox to the boolean field (MyTeamHasTasks), this route does not give me any issues...  Makes me wonder why it doesn't work they way I initially implemented it as it achieves the same thing.

Any idea as to how I can get around this?  I do not think this is a bug, I feel like I have possibly not implemented this accurately.

I'd like to do this without ANY code-behind.

I just want to disable (grayed-out, un-clickable) the "funnel" icon of the filter on the radgridview header and not HIDE it.

Is there easy way to do it without creating a custom filter?

Cheers
