Hi,
I have a button with a ListBox control as part of its dropdown content. The content also contains 'ok' and 'cancel' buttons to allow the user to dismiss the dropdown when they are done. I have run into a number of problems trying to get this to work. I don't know whether they are bugs or whether I should be doing this another way so I look forward to any comments that you may post.

Here they are:

1. When a listbox item is selected then the dropdown content closes. This happens because RadGallery.cs registers a handler that unconditionally closes the dropdown when a listbox selection changes. This seems like the right thing to do since there needs to be a way for the dropdown to close but inhis case it is undesirable since I have buttons that serve that function. What I am wondering is if an attached property could be created that could give the handler some direction about whether it should close the dropdown. I would then be able to attach this property to my listbox and the handler would know that it shouldn't close the dropdown.

2. I got around the 'listbox selection closing' problem by setting RadRibbonDropDownButton.KeepOpen = true but this brings on the next issue. 'KeepOpen' appears to work not by preventing the dropdown content from closing but by reopening after its been closed. This isn't obvious when interacting with the control but if you look at the call stack then you'll see that there is a call to 'IsOpen = false' that is quickly followed by a call to 'IsOpen = true'. The side effect of this is that every time a listbox item is selected then the 'DropDownOpening' event is raised. This is undesirable because I have some state variables that I would like to set only when the dropdown content is first displayed. My expectation was that this event would get called only when the drop down was opening and not additionally whenever a listbox item was selected.

3. This one is really more of a question followed by what may be a request. In order for my 'ok' and 'cancel' buttons to close the dropdown programmatically they must determine the RadRibbonDropDownButton control that the dropdown belongs to but I could find no straightforward way to do this other than giving the button a name and then referring to that name in the handlers. What I'd really like to do is to get this to work in a more generic way since my desire is to move the 'ok' and 'cancel' button handlers into a class which I would then use as a base class for other dropdown content. So the question is whether there is a way to do this that I am missing. If there is none then I have a request, which is for the RadRibbonDropDownButton to attach a property to the topmost visual of its dropdown (a popup I suppose) that indicates the RadRibbonDropDownButton that owns the dropdown.
Thanks and best regards,
Pete

Hi. 

<telerik:GridViewDataColumn DataMemberBinding="{Binding ActVoltage,TargetNullValue=NA}" DataFormatString="0.###" Header="Actual Voltage"/>

Normal output is that I want this column to only show three decimals. However, when the underlying value is null, I want it to show the text "NA". 
It seems that I can't have both. When I included the formatstring, "NA" stopped showing up. I understand why, but not how to solve it.

The underlying type is nullable double.

Hi,

I'm using VS2005 / .Net 3.5 and Telerik V2012.1.0326.35 and sometime, when I clicked on the filter dialog icon in the column header of my radgridview, the filter dialog appear not completly.

Hi,

My document contains a lot of custom annotations, where each annotation has self generated unique ID.
Is it possible to bring a defined annotation into view based on its ID value?

i.e. If the annotation in question is at the top of the first page, but currently I have the last document page in view, can I make radrichtextbox auto scroll to the annotation when required?

Is it just the case of enumerating through the document searching for the specific annotation ID then setting the caret position to the position of the found annotation field?



Thank you for your time,

Rob

Dear Telerik Team,

we use the ScheduleView and have found a little problem.

When you open the calender, and look at the week numbers you will recognize that
the week numbers are always 1 Week higher than in reality.

That's why, because the calender starts in January with Week Number 2 (see attached Screenshot)

I found a post in you forum, that this ahppens because of the ISO Standard of the Culture Info

http://www.telerik.com/community/forums/aspnet-ajax/calendar/week-numbers-is-wrong.aspx

Is there any way to tell the WPF control also to use the right ISO Standard ?

best regards
Rudi

Dear staff, 
  A control button RadRichTextBoxRibbonUI was created to display or hide the comments.
  In the codebehind is intercepted on the click event of the button and the code is executed:


The code runs but the view does not update, or do not see the comments.

In the scenario we are working with, we have a grid that displays some dynamic content, and then we have our 'help' using RadPane docked to the right.

I'm using RadDocking to host the RadSlitContainer which houses the RadPane (our help pane), but not able to get it adopt the styles I apply unless it is nested inside the DocumentHost element.

The issue is, My scroolviewer of dynamic content only seems to work with RadDocking if it is nested in the DocumentHost element, with the RadSplitContiner outside.  Reversing these produces ill results--no resizing when the dock is pinned, etc.

I've attached a screen grab of my heierachy...can someone point me in the right direction of how to properly set this up so that my dynamic content will dominate but then resize should the user pin the expanded dock on the right?

Is it normal behaviour for RadPanes to ignore assigned styles when outside of DocumentHost?

Hi,

I have a combobox (with checkboxes inside it) that is inside a RadToolbar. I have an issue where the combobox always closes when a checkbox is checked. I've noticed that when the combobox is not inside a Toolbar then it will stay open to allow me to select multiple checkboxes. I would like to have the CB inside the toolbar so I'm looking for a fix. Is this a bug? Is there a fix?



Thanks

Hello there,

I need to dynamically draw a RadDiagramShape nested in a RadDiagramShape. I need to allow user move the internal/inner RadDiagramShape (just like the outer/container RadDiagramShape can be moved within the RadDiagram). I created a custom WPF control and I set its ContentControl property as a Canvas. Then I'm adding all children to the canvas Children collection from code behind.
The problem is that the added RadDiagramShape controls can not be moved/manipulated within the nested Canvas.
How do I allow this nested RadDiagramShape to be moved?

Thanks,
