Hi,

I have a grid with servere Column Groups.
-- "Base Product" "End Product" "Sales"
And the user is enabled to drag columns.
My problem - the user can now drag the column "Number of items" from Sales to "somewhere".

This results in a "splitted group header".

Is there a (simple) way to restrict dragging of a column within a column group?

And just another question - how can I place text on the default loading indicator?
I found no template for it - and also no property like "Loading content" or so.
All I want to do is to place a text "Loading Items please be..." on the indicator.

Font problem

Hi all,

I'm using the Crystal Reports 9 - "Export to disk file" option to generate pdf file(s) from my reports.
This works fine: I can open the reports using Acrobat Reader and they look perfect. However, as soon as I load the pdf in the RadPDFViewer (version 2012.2.1009.40), the report becomes completely unreadable (replacing the text with strange font characters as if the font is not there).
I tried it with Arial, Times New Roman, Courier, Aharoni... but nothing works.

Strangely enough: If I "print" the same report to a PDF printer to generated the PDF (instead of export), then it works fine !

Any help would be very much appreciated!

Kind regards,
Wim

Deployment of Telerik DLLs

I'm an Installer developer for a company that's to expand its use of Telerik. A version of one of our apps has a set of Silverlight-related Telerik DLLs. Another new app which I'm tasked with packaging has another set of WPF-related Telerik DLLs. Some of these DLLs have identical names (such as Telerik.Windows.Controls) but don't appear to be identical; at least they have different version information. My questions are this: Are they just different version of what is functionally the same DLL? If so, are they truly backward-compatible, e.g., if one app uses an older set of Telerik binaries, and than another app which uses a newer set of the same binaries is deployed on the same box (and same folder!) will the older app continue to work?

Thanks!

Scrolling/zooming bug

Sample: "Default UI RadImageEditor"

Scrolling/zooming doesn't work until you touch the zoom slider. I see this behavior in my test application too.

PropertyValueChanged when selecting a dropdown element

Hi,

We have a field which let us select a Texture from a DropDownList in a PropertyGrid. Every thing works fine, excepts we want to end the edit of the field when we choose an option from the DropDown. Right now we have to click elsewhere of hit Enter to do so. We have an other field that needs to be updated as soon as this Texture field changes.

Retrieve radtreelistview child node

Hi,

I am using radtreelistview in order to display hierarchical data. I need to find all the child node for a particular parent node .
I tried the following code

var

childNodes = (currentrow as Telerik.Windows.Controls.TreeListView.TreeListViewRow).ChildrenOfType<Telerik.Windows.Controls.TreeListView.TreeListViewRow>();

But the above code doesn't return anything.
Is there an in-built feature available in the current version? The control version used is 2011.1.223.35.

Unable to use new RadMap control...

I installed the new Q1 2010 yesterday. I created a new WPF application in VS2010 RC and tried using the new RadMap control.

I could not find the RadMap control in the toolbox.
I tried adding a "using" declaration for "Telerik.Windows.Controls.Map". The "Map" portion could not be resolved. The rest was fine.
When I tried browsing to add the assembly as a reference. I could not find the assembly.
I tried this with .NET 3.5 and 4 projects. Same results.
I uninstalled Q3 2009 from my system then installed Q1 2010. Subsequently, I uninstalled / installed Q1 2010 a few times trying to resolve this.

Any suggestions?

Thanks,
Scott

Setting up an EventToCommand with selected cell

I'm converting an existing DataGrid to a RadGridView. On my DataGrid I have trigger set up to fire whenever I right click on a cell. It looks like this:

<i:Interaction.Triggers>

<i:EventTrigger EventName="MouseRightButtonDown">

<mvvmcmd:EventToCommand Command="{Binding ItemClickedCommand}" CommandParameter="{Binding CurrentCell, ElementName=ContractProxyDataGrid}" />

</i:EventTrigger>

</i:Interaction.Triggers>

I'm trying to do a similar thing with my RadGridView but binding to CurrentCell gives me a null parameter. What I am trying to get at is the DataGridCellInfo (or something similar) of the cell that was right clicked. What should I be binding too?

Thanks.
