Is there a way to keep the ribbonbar tab selected when the ribbon is collapsed?  I am want to achieve the pageview's tabbing and page switching features along with the ribbonbar's ribbon formatting.  If collapsed, the ribbonbar doesn't appear to have a SelectedCommandTab value present.  I need to keep this property and the appearance of a selected tab when the ribbon bar is collapsed.

Is this possible, or is there a better solution?

Hello

I know that this question has been discussed many times, I have tried various solutions but I have a strange behavior that I can not correct.

I use a 4K 3840x2160 monitor, Visual Studio 2015, .net 4..7

I have a fairly large WinForms project with many forms and user controls.

In the development environment some of the forms or user controls are displayed in "readable" font sizes and other forms or user controls are displayed in very small fonts.

I set the autoscale property of the form to DPI and I set it to inherit to the use controls - I have tried to change this propertx to other values without any visible change.

I trust that the "final" application used on normal resolution displays (1920x1080 or smaller) will work properly but in teh develpment environment it's very uncomfortable to work with very small fonts.

Is there something I can do to correct this abnormal behavior ?

Thanks in advance

Hello,

I am currently implementing the RadScheduler control where I have already replaced the AppointmentEditDialog and the EditRecurrenceDialog.

Could you point me in the right direction how to replace the message-dialog when you move/resize a single item of a recurrence appointment?

(See attached image)

Good day,

The little calendar could be activated/popup with hotkey F4 for GridViewDatetimeColumn and the calculator for GridViewCalculatorColumn. Is this hotkey changeable, said change to F2 to bring up these?

     Hello , as I learned from your website , there is a method to create pdf from gridview.

But I have a problem , could you give me information about this?

Hello.

I'm considering using Scheduler but I need to customize recurring appointments in a way that I do not know how to do it.

I need recurring appointments to occur only within an interval.

For example, in a HourlyRecurrence Appointment I'd need only repeat in the interval from 10:00 to 17:00 hours

or in a Daily appointment that only ocurs between 5th and 25th of each month.

Would this be possible?

Thx.

Hi there,

We're facing this error in one of our recent deployments to one of our customers and it has never happened before to us. When it's happening, a big red cross it's displayed instead of one of the controls, usually in the parent window using either GridView or PageView.

There are different stack traces for the same exception message, but all of them involve some calls to Telerik controls and nothing to our own code. See some examples from the most common errors:

Stack Trace 1:

Stack Trace 2:

Stack Trace 3:

Unfortunately, it's happening very randomly, so we're totally unable to replicate it, but it seems to be related with our client's users still using Windows 7 (yeah, quite old, I know).

We have already checked the number of User objects and handles created by the application when crashes and they look fine (between 500 and 1,000 for both in the worst cases). Regular machines are laptops using Windows 7 with 4GB of memory.

We don't know what else we could check, but we were wondering whether you have ever faced an error like this or not. Any light or ideas into this case will be welcomed.

BTW, the Telerik version we're using is 2018.1.220.40 (mainly GridView and PageViewer) and the .NET Framework version is 4.6.1.

Thank you in advanced.

I want to format group row's title with the following requirements:

1. Change the group row's default title:

    I use the GroupSummaryEvaluate event, but I could not get the grouping  column's header text,from the example, I could only the the column's name(e.SummaryItem.Name). I hope to get the column's header text to continue my work.

2. Change the group row's background color or foreground color

   I hope the change the default color of the group row

3. Add simple controls to the group row. e.g. I want to add an label with some red text to the group.

Is this the same as RadDropDownList?

Or two different objects.

I am trying to see if RadDropDownListElement is capable of doing multi-selects on the drop down list.

I see this in docs online: radDropDownList1.DropDownListElement.SelectionMode = SelectionMode.MultiExtended

But not seeing this for the RadDropDownListElement.

Can I use the RadDropDownList in the radRibbonbarbuttongroup?

Thanks.
