Hello everybody,

can anybody tell me if it is possible (and if how) to use windows default spellchecking feature?

Below there is a complete codesippit how to accomplish this with a standard control. In this sample a textBox will be added on Form1.vb. I want to do exactly the same with a radTextBox. Type some missspelled text an you will see the spellCheck feature.

Thanks for answering.
Mat

When populating a schedule with appointments from my database, i want to have the appointments automatically have their resources (people) assigned.  How does this work?  Am I to assign the ResourceID of the AppointmentMappingInfo object the resource ID from my database?  I am using a business object for my appointments and populating the Resources collection of the RadScheduler manually with the resource name and ID.

What are the options of getting the appointments and resources to be related to each other so when the schedule is displayed, the resource drop down in the Edit Appointments Dialog is assigned the resource?  Also, when viewing the schedule in resource grouping mode, the resources are assigned to their appointments.  

Me.RadScheduler1.AppointmentFactory = New CustomAppointmentFactory

 

 

 

 

dataSource.EventProvider.AppointmentFactory = RadScheduler1.AppointmentFactory

 

 

 

Dim appointmentMappingInfo As New AppointmentMappingInfo()

 

appointmentMappingInfo.Start =

 

"Start"

 

 

 

 

appointmentMappingInfo.[End] = "End"

 

 

 

 

appointmentMappingInfo.Summary = "Subject"

 

 

 

 

appointmentMappingInfo.Description = "Description"

 

 

 

 

appointmentMappingInfo.Location = "Location"

 

 

 

 

appointmentMappingInfo.UniqueId = "Id"

 

 

 

 

appointmentMappingInfo.Exceptions = "Exceptions"

 

 

 

 

appointmentMappingInfo.ResourceId = "EmpID"

 

 

 

 

dataSource.EventProvider.Mapping = appointmentMappingInfo

 

 

 

' assign the generic List of MyAppointment as the EventProvider data source

 

 

 

 

dataSource.EventProvider.DataSource = appointments

 

 

 

Me.RadScheduler1.DataSource = dataSource

 

Hi,

In the DateTimePicker I'm looking for an event which happens when a user changes the date (by mouse or keyboard) but not when a date is set- (for example:  DateTimePicker1.Value=DateTime.Now)

In other controls I found events or properties which supported this scenario, but in this case I couldn't find.

 

Thanks

Hi there,

I have just upgraded my application to the latest version and discovered a weird bug with the GridView_CellFormatting event.

The previous version was trying to format the colors of the current cell depending on the value of another cell in the same row.

To simplify this behaviour, we can just look at 3 columns in a grid. Column 1: ID, Column 2: Name, Column 3: Status

If the status is True, Column 1's colour would be Blue and if the status is False, then column 1's colour would be Red.

in the previous version, the code was working fine..but with the new version, it seems that the Name column would also be affected.

and everytime the grid is refreshed through some random action e.g. moving of scrollbars, the name column's forecolor would change randomly..to either Red or Blue when those colours should only be affecting column 1.


P.s. I think The #2 example in http://www.telerik.com/help/winforms/formatting_cells.html is wrong... RowInfo.Cells[ColumnName] does not contain the CellElement property.

Dear Sir,

I wanted to export gridview data into .pdf file. I gone through kb and it tells that you need to create an object of ExportToPDF. Now I cannot find the specified class in the Telerik.WinControls.UI.Export namespace. There is only one class in the given namespace i.e. ExportToExcelML!

I am using Telrik Controls for WinForms Q1 2010.

Thanks,
Divyesh

The title of the thread says it all:

Me.RadGridView.Rows().Cells().Style.BackColor = Color.Yellow

Me.RadGridView.Rows().Cells().Style.BackColor = Color.Yellow

Me.RadGridView.Rows().Cells().Style.BackColor = Color.Yellow

Me.RadGridView.Rows().Cells().Style.BackColor = Color.Yellow

Me.RadGridView.Rows().Cells().Style.DrawFill = True

I understand that the cell element is gone but this code worked last build using the CellElement but not with the new Style object. I would assume there is a way to change the back color of a cell at run-time. Please give me the correct way so my code will work. Thank you.


OK More Info.....

Me.RadGridView.Rows().Cells().Style.ForeColor = Color.Yellow

this works!!! soooo....just maybe this is something you need to fix with backcolor.. :-)

I find it hard to believe there is no current way with the latest version to set the backcolor of cells at run-time, so any code that works I'll take at this point.

hi,
When I edit with GridView when the wizard does not update table
please help..
thankyou

I'm working on an inventory form and one of the (optional) fields is ReplacementDate. Obviously, for equipment that is still in service, there won't be a value for the ReplacementDate. Is there a way for either the RadMaskedTextBox (with a DateTime mask) or RadDateTime picker to handle a nullable DateTime natively, or do I have to use a numeric mask and handle the Validating event?

Hi,

i've just tested a bit and scrolled through one of my several gridviews that i am using in my application and...whooops...
