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?

[Solved] 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;

[Solved] 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

Multiple X-Axis for each Rowgroup one

Hello,

I am using RadPivotGrid together with RadChartview.
I would like to have a X-Axis for every Rowgroup in the Pivotgrid.
Because the Rowgroups are hierarchic the X-Axis should also be Stepped.
Excel does this. How can I do this in Telerik Chartview?

best regards
Thomas

Modifying font and backgroud of group by row in RadGridView

I have a RadGridView that is using the group by functionality.

When grouping by a column, the group by rows are created.

I would like to change the font, background color, etc. of the group by row, but cannot figure out how. (They don't seem to take any formatting from the rows before the group by)

Thank you.

Disable the resizing of columns (splitter)

Hey there,

I am browsing the properties/methods of the property grid for a while because I want to disable the resizing of the columns in the property grid. Something similar to 'AllowVariableSpliterPos'.

Is this supported?
Thanx!
