I have a gridview on a winform and the datasource is a datatable, after I sort though the underlying datatable does not update and this makes other operations wrong. using the underlying datatable values and the row number for it instead of the visible data in the grid.
any assistance appreciated as this is a very late discovery.

I just want to add I am using the q3 2010 set grid control. I do not really have any extra sorting settings, other than allow sort true. My expectation when I hit the column header is that it will do a switches between asc and desc as default.

Recurring Appointment Start Dates

I'm on the newest version of the telerik winforms. (2015_2_623)

After updating, the first occurrence of recurring appointments no longer show up.

This appears to occur when using any time zone that comes before UTC time.(Any "-" time)

Is there a fix for this issue?

Logging Support in Telerik Controls

Hi,

May I know is there any plan for Telerik to include Logging support in various controls? So that developers don't need to write their own log framework or use any other third party logging tools.

Everything has to be built-in to deploy an integrated solution solely using Telerik Controls :-)

Thank you.

Regards,
Jenson

DropDownList popup location after resizing items width

Hi,

I used this solution to increase my DropDownList popup when item text is longer than DropDownList size. But when I open the DropDownList for the first time, it goes off the screen (my DropDownList is at the right edge of the form and popup isn't positioned correctly and goes right off the screen).

Then when I close and open DropDownList, the popup position will be correct and after that everything is OK.

Should I add something at the end of "PopupOpened" event after resizing items?

How to delete element from layout

After placing more elements in the layout than I realized I needed, I tried to delete the extra elements but all I can do apparently is to 'Hide' the extra elements.

Is there a way to delete the extra elements rather than 'Hide' them?

RadScheduler and RadWaitingBar

Hi to all,

I need to show a WaitingBar during mapping my appointments. How can I do this?

Actually I have a custom control with this structure: a Panel that contains sequentially RadNavigator (Dock.Top) > RadScheduler (Dock.Fill) > RadWaiting (Dock.Bottom)

I can't set a DataSource directly to the database, I used a BindingList<CustomAppointment>

During intercept some event's scheduler and navigator, fire a my delegate event NeedData that asks to Windows program to execute load data for specific period.

In this case if items of my BindingList<CustomAppointment> contains a lot of items, the primary thread is freezing.

I would use a RadWaitingBar to show a "waiting period" to user.

How can I do this? Normally I resolve this problem.... but on WPF Application with RadBusyIndicator :-)

01.#region navigator events

02.void NavigatorNavigateForwardsClick(object sender, EventArgs e)

03.{

04. if (NeedData != null)

05. NeedData(scheduler.ActiveView.StartDate, scheduler.ActiveView.EndDate);

06.}void NavigatorNavigateBackwardsClick(object sender, EventArgs e)

07.{

08. if (NeedData != null)

09. NeedData(scheduler.ActiveView.StartDate, scheduler.ActiveView.EndDate);

10.}#endregion#region scheduler eventsvoid SchedulerActiveViewChanged(object sender, SchedulerViewChangedEventArgs e)

11.{

12. if (NeedData != null)

13. NeedData(scheduler.ActiveView.StartDate, scheduler.ActiveView.EndDate);

14.}

01.// create and configure a scheduler binding source

02.schedulerBindingDatasource = new SchedulerBindingDataSource();

03.// map the MyAppointment properties to the scheduler

04.appointmentMappingInfo = new AppointmentMappingInfo();

05.appointmentMappingInfo.Start = "Start";

06.appointmentMappingInfo.End = "End";

07.appointmentMappingInfo.Summary = "Subject";

08.appointmentMappingInfo.Description = "Description";

09.appointmentMappingInfo.Location = "Location";

10.appointmentMappingInfo.UniqueId = "Id";

11.appointmentMappingInfo.Exceptions = "Exceptions";

12.appointmentMappingInfo.ResourceId = "ResourceId";

13.appointmentMappingInfo.StatusId = "StatusId";

14.appointmentMappingInfo.BackgroundId = "BackgroundId";

15.

16.schedulerBindingDatasource.EventProvider.Mapping = appointmentMappingInfo;

17.// assign the generic List of CustomAppointment as the EventProvider data source

18.schedulerBindingDatasource.EventProvider.DataSource = customAppointments;

19.

20.if (customResources != null)

21. LoadCustomResources();

22.

23.scheduler.DataSource = schedulerBindingDatasource;

Category Show after hiding all properties at runtime.

I am using

radPropertyGrid1.Items["Text"].Visible = variable;

to hide or show properties at run time.
The only negative side effect I'm seeing is that the Category doesn't disappear.
Is there a way to hide the category as well?

I've attached a picture of it visible, and of it hidden.
The category is Motion System Locations.

Treeview node selection

Hi,
I have problems with with Q2 2011 :
- every node of a treeview in my application is selectable not only by clicking over the node text, but also if I click on the line containing the node, while my goal is that only when I click on the text the node is selected; if I click outside the text of the node for example on the same line of the node, no nodes must be selected.

I Have an other problem with the RadToolStripSeparatorItem: I can' t set the width of the line or change the style of the item; my goal is to create a thinner line than the default one.
As attachement a screenshot of the desired effect and the actual effect
