Force CellFormatting to Update Font at Runtime

Goal: I need be able to set the font size of a grid's cells at runtime based on user input.
Design: I have a user control with a telerik RadGrid on it. The grid has a mixture of datacolumns and imagecolumns. The user control exposes a property called FontSize.
Problem: I can't get Grid_CellFormatting to be hit once the FontSize Property is changed.

I need some way to force the grid to reformat all the cells when the FontSize Property is set.
I can mouse over the cells which causes Grid_CellFormatting to fire, at which time the cell font is updated with the new font size, but i need this to happen programatically.

My User Control:

    
              Private Sub Grid_CellFormatting(ByVal sender As Object, _ 
        
                    ByVal e As CellFormattingEventArgs) _ 
        
                    Handles grid.CellFormatting 
        
                    Dim f As New System.Drawing.Font("Arial", My.Settings.Grid_FontSize, _ 
        
                        System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, CType(0, Byte)) 
        
                    e.CellElement.Font = f 
        
                End Sub

    
                Public Property FontSize() As Single Implements IReportGridView.FontSize 
        
                    Get 
        
                        Return My.Settings.Grid_FontSize 
        
                    End Get 
        
                    Set(ByVal value As Single) 
        
                        My.Settings.Grid_FontSize = value 
        
                        My.Settings.Save() 
        
                        My.Settings.Reload() 
        
                    End Set 
        
                End Property

I've tried adding me.grid.Update, Me.grid.Refresh after the My.settings.reload, but nothing seemed to trigger the CellFormatting event.

Your help is appreciated.

Thanks.

app.config 'openaccess' section error

hello

when I try to copy an existing user control from one form to another, I get the following error:
"an error occurred while processing this command. the 'openaccess' section cannot be found in the application's configuration file"

when I try to add a new user control to a new form I get the following error:
Failed to create component 'AddEquipmentUC'. The error message follows:
'Telerik.OpenAcccess.Exceptions.ConfigurationException: The 'openaccess' section cannot be found in the application's configuration file. at Telerik.OpenAccess.Config.XML.ConfigFileReader.GetOpenAccessNode(Boolean fromAppConfig, String configFileName, XmlTextReader & xmlTextReader, Boolean throwException)................etc

I am using TortoiseSVN for source control. Everything works fine except for this. I suspect Tortoise is keeping it from authenticating the user/password specified in the openaccess element in the app.config section.

any ideas why this is occurring and how I can fix this? this is really not good for development schedules and I really hope there is a fix for this OTHER than removing source control.

Row edit Status

Hi

I am using an example you provided in a previous reply to implement drag and drop from a radgridview. When using the mouse down event to pass row information into an array if the row being dragged is being edited the application crashes completely. How do I handle this (test for the row edit state) to prevent the crash?

Regards

Joe

Private Sub RadGridView1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles SubContractgrd.MouseDown

Try

downpoint = e.Location

rowtodrag = GetRowAtPoint(Me.SubContractgrd, e.Location)

ContArray(0, 0) = (rowtodrag.Cells(0).Value)

ContArray(0, 1) = (rowtodrag.Cells(1).Value)

ContArray(0, 2) = (rowtodrag.Cells(2).Value)

If Not IsNothing(rowtodrag.Cells("Text").Value) Then

ContArray(0, 2) = Replace(StrConv(rowtodrag.Cells("Text").Value, VbStrConv.Uppercase), " ", "")

Else

ContArray(0, 2) = (rowtodrag.Cells(1).Value)

End If

If Not IsNothing(rowtodrag.Cells("D").Value) Then

ContArray(0, 3) = "SD"

End If

If Not IsNothing(rowtodrag.Cells("V").Value) Then

If Not IsNothing(ContArray(0, 3)) Then

ContArray(0, 3) = "SDV"

Else

ContArray(0, 3) = "SD"

End

End If

Catch ex As Exception

If Err.Number = 91 Then

Err.Clear()

Exit Sub

Else

MsgBox(Err.Description & Err.Number)

End If

End Try

End Sub

Help with updating STATUSSTRIP element from MOD procedure

I have a STATUSSTRIP placed on a form called DESKTOP, which is always ON TOP and present. This form calls and runs everything in my VB.NET application, and happens to be the STARTUP form. I call an PROC which is one of my MODULES instead of CLASS. This PROC happens to run for a long time. I would like for the PROC to post an update to the STATUSSTRIP located on my DESKTOP form (calling form) using the STATUSSTRIPLABEL.VALUE1 and STATUSSTRIPLABEL.TEXT properties. How would I accomplish this?

I tried using DESKTOP.STATUSSTRIP.TEXT = "Something..." and it would not work from my SUB. Basically, my code would look like this on the FORM side.

PRIVATE SUB DESKTOP_ONLOAD() HANDLES FORM_LOAD

    ....
    Call gsDoSomething
    ...

    ME.STATUSSTRIPLABEL.TEXT = "Ready..."

END SUB

The PROC being called will live in a MODULESOMETHING.VB file in my project and its code will resemble...

PUBLIC SUB gsDoSomething()

    ....
    DESKTOP.STATUSSTRIPLABEL.TEXT = "Doing something..."
    ...

END SUB

Any help or suggestion would be greatly appreciated.

Feature or Bug?

On the calendar with multi-select disabled...

when i click on a date, the selected date is set to the date i selected but when i unselect, rather than go back to today's date, it is set to

1/1/1980.

I have changed this in code so that on click, if the date it 1/1/1980 it sets it to today's date.

on load i even change the focused and selected dates to today but i still see 1/1/1980 register when i unselect a date.

Can someone explain this behavior?

Appointments 30mins or less

I'm trying out the scheduler component, and I will need to default to having appointments as multiples of 30 minutes.

The way I think I should be doing this is

    
            SchedulerDayView view = radScheduler1.GetDayView(); 
        
            view.RangeFactor = ScaleRange.HalfHour;

But when I do that, and then try to create appointments, the start and finish time boxes are greyed out and the appointments always end up being all day appointments.

I am using a custom Appointment type and custom EditAppointmentDialog, but everything is working fine for me until I set the RangeFactor.

I'm using 2009 Q2 SP1.

Can anyone give me any hints as to why this would not work?

Thanks,

Marcus.

RadForm NOT a drop-in replacement for a Widows Form ?

excuse the typo in the topic title ...

2009 Q2
When I simply change a Form to inherit from RadForm instead of standard WinForm Form, a lot of things don't work as expected anymore. For example Saving and Restoring Windows Position etc. does not work identically.

Also I have a problems with RadForms that were created with earlier Versions of the Controls. Here, anchored Buttons suddenly do not appear at the right place at runtime. I guess it has something to do with the non-client area drawing / sizing as the child controls seem so be moved upwards about the height of the window title bar.
These issues I cannot reproduce with sample code as it would mean setting up a development machine with older versions.
