Hello All,

     I have a quick and easy question about setting up a cell datatemplate.  I have a class that has two properties: a boolean value and a string value.  In my app, I have created a collection of this class and would like to display it in a grid.  I would like to display the boolean value as either a check-mark or a x-mark as in the example image I've attached...  I'm pretty sure this can and should be done as a celldatatemplate, but I have no idea as to where to start...  Could someone please point me in the right direction???  Is there a good example of this or is there a good explanation of setting a template up somewhere out there???

 

Thanks in advance,

 

Kevin Orcutt

I've got some weird behaviour going on, its probably something I've done, but I can't seem to work out whats going on.

I've set up two stack panels on my usercontrol, one called New Trip and one called New Misc Job - on initialize of the usercontrol I'm setting up the DragDropManager - actually all I'm doing is specifying the methods for DragIntialize like so :

DragDropManager.AddDragInitializeHandler(newTripDrag, NewTripDragInitialize);
DragDropManager.AddDragInitializeHandler(newJobDrag, NewMiscDragInitialize);

 

When the user drags one of the stackpanels onto the scheduleview, I've got some custom dragdropbehaviour going on, but at the end of the Drop method, it always calls base.Drop() and this is where the weird behaviour comes in, when I'm dragging a trip, it works perfectly and the trip is selected afterwards, but when I drag a misc job, it fires off the SelectedAppointment method with a null value which makes nothing selected afterwards.

Why would it be calling the SelectedAppointment for one and not the other, is there something I can change to stop this from happening, I've attached the Call Stack from the point of base.Drop() to Setting the SelectedAppointment for when I dragged a Misc Job (if that helps).

So I seem to have a memory leak. I am using JustTrace and Memory Profiler.  What happens is in using the RadListBox on one of my views, I see InternalScope objects keep adding up everytime I open the view that has that RadListBox.  But I don't know what that class is used for or what would make that problem?  Any detailed help on how to find the root of this problem would be appreciated.  Been trying to figure it out for days and have commented out templates and styles.

Hello,
I'm using telerik control tools for WPF UI ver: 2015.1.0401.45
I have noticed that radlistbox has a huge memory leak. On replacing radlistbox with Microsoft listbox, memory leak does not occur.
I'm attaching the demo project (replace fileextension of file from  .jpg to .zip).
This project demonstrates the problem of memory leak. Actually the memory leak occurs on data binding
I've remarked the Microsoft listbox in xaml, so to prove my claim, just use Microsoft listbox instead  of radlistbox and see the difference in memory usage of the processes.
Do you have a patch to fix this issue ?
Thank you,
Alex

Hi!

I would like to suggest that page numbers and a page title be optionally added when exporting a GridView to Pdf. This should be easy to implement since RadSpreadProcessing already has a class "HeaderFooterSettings". Just expand the "GridViewPdfExportOptions" with two options: ShowPageNumbers (true/false) and PageTitle (string). Should be done in no time.

Regards
Heiko

I had browsed for a similar issue & seen the below link which had the same issue of mine, its said by Telerik that issue is resolved but I could not get the fix anywhere.

http://www.telerik.com/forums/radwindow-autosize-on-runtime#e9i78SNv102TDO2DCh_z6g

I have created a RadWindow and its content is set to a wpf view which has some controls & a RadExpander. I want this RadExpander to be shown when its expanded(my RadWindow Width should be resized accordingly).
I have set ResizeMode="NoResize" and SizeToContent="True" for my RadWindow. But RadWindow doesn't seem to adjust according to its content, how can I achieve It?(I have not set any Height or Width to my RadWindow)

Is SizeToContent changed to Enum to support WidthAndHeight or what is the fix for the problem given??

Hello guys,

I have created a RadWindow as a User Control and It has ResizeMode="NoResize" and SizeToContent="True". Inside the content I have an Stackpanel that is collapsed and when I turn It visible on runtime, the content below is hidden because the RadWindow doesn't resize, how can I achieve It?

Hi,
I have a RadCombobox with following properties:

IsEditable="True"
OpenDropDownOnFocus="False"
TextSearchMode="Contains"
IsFilteringEnabled="True"
UpdateTextOnLostFocus="False"
CanAutocompleteSelectItems="False"
IsReadOnly="False"

And when user types, I open the dropdown with following code:
comboBox.IsDropDownOpen = true;

my problem is:
when a user wants to insert some words in exist text, whole text will be clear.
what I can do to solve this.

My project:

Hi,

I'm talking about class "Slot" in Telerik.Windows.Controls.ScheduleView namespace.

Let's take a look to Slot(IOccurrence occurence) constructor, line 14 may cause NullReferenceException:

01.public Slot(IOccurrence occurence) : base(occurence)
02.        {
03.            IAppointment appointment = occurence as IAppointment;
04.            if (appointment != null)
05.            {
06.                if (appointment.RecurrenceRule != null)
07.                {
08.                    this.RecurrencePattern = appointment.RecurrenceRule.Pattern;
09.                }
10.            }
11.            else
12.            {
13.                Occurrence occurrence = occurence as Occurrence;
14.                appointment = occurrence.Appointment;
15.                if (occurrence != null)
16.                {
17.                    appointment = occurrence.Appointment;
18.                }
19.            }
20.            this.TimeZone = appointment.TimeZone;
21.            this.Resources.AddRange(appointment.Resources);
22.        }

Using the sample below, how would I get the "VendorName" property to display next to the values of each series in the trackball info popup, just like it would appear in the legend?

 

<telerik:RadCartesianChart x:Name="chart" Palette="Summer" Height="209">
