[Solved] Cell_Formatting any effects

Hi to all,

I have this method, I'm trying to format in backcolor only column editable.

I setted all columns with ReadOnly = True, and then I setted only particular Column ReadOnly = False

Now I would test if I format cells by Name or by ReadOnly status, but in both ways, BackColor appears Yellow only when I doubleclick into editable cell.

I would show to user the editable columns with Yellow backcolor.

How can I do?

01.Private Sub UpdateCellFormatting(ByRef e As CellFormattingEventArgs)

02.

03. Dim _IsEditable As Boolean = False

04.

05. If _SelectedItem IsNot Nothing Then

06.

07. If _SelectedItem.Personalizzazione = ListinoCliente.StringaListinoStandard Then

08.

09. If e.CellElement.ColumnInfo.FieldName = "PrezzoListino" Then

10. _IsEditable = True

11. End If

12.

13. Else

14.

15. If e.CellElement.ColumnInfo.FieldName = "Sconto" Then

16. _IsEditable = True

17. End If

18.

19. End If

20.

21. End If

22.

23. If _IsEditable Then

24. e.CellElement.BackColor = Drawing.Color.Yellow

25. Else

26. e.CellElement.ResetValue(LightVisualElement.BackColorProperty, Telerik.WinControls.ValueResetFlags.Local)

27. End If

28.

29.End Sub

Dummies guide to combo boxes

Hi

I am having big issues (lack of knowledge) with creating combo boxes on a gridview bound to a dataset, Can someone please point me in the right direction?

My current setup of the gridview is a SQL view that fills a dataset, which is then bound to the gridview. I have a column called 'Course', which is a column generated within the view that uses the Course_ID from the main User Table to lookup the Course name from the Course Table (see attachment). I would the Course column to be a combobox, when I auto generate the columns from the dataset it creates it as a textbox currently; and for the course names (from the course table) to be the options in the drop down . I would then like the user to see the selected options after a dataset update. Is there a way of doing this?

Thank you.

Add New Row - Winforms GridView Event

Hello, this is probably a really simple question, but I can't figure it out right now. I'm using the Winforms GridView control, and I want to be able to add a new row within the gridview control. I do have "AllowAddNewRow" set to true. Which event is being initiated when you add a new row to the grid? I easily was able to use the "RowDeleting" event when I delete a row, so I figure that there would be a "RowAdding" or a "RowAdded" event. But, there wasn't. I simply want to Add/Update/Delete rows. It's pretty simple with the ASP.NET control with the Insert,Update,Delete command events, but I can't seem to find anything similar in the winforms control. So, which event is used to Update a row, and which event is used to Add a new row (I want to be able to add the new row using the "click here to add new row" area), or what is the process to implement these 2 events?

I'm using the Q3 2007 V5 version.

thanks,
monirak

                    {  
        
                        SchedulerMonthViewElement monthView = this.schRates.SchedulerElement.ViewElement as SchedulerMonthViewElement;  
        
                        Telerik.WinControls.RadElementCollection childrenCollection = monthView.Children[1].Children;  
        
                        foreach (MonthCellElement cell in childrenCollection)  
        
                        {  
        
                            if (cell.Header.Selected == true)  
        
                            {  
        
                                cell.Header.Selected = false;  
        
                            }  
        
                            if (childrenCollection.IndexOf(cell) == 34)  
        
                            { break; }  
        
                        }  
        
                    }

                    private void UnselectAppointments()  
        
                    {  
        
                        foreach (IEvent appointment in this.schRates.ActiveView.Appointments)  
        
                        {  
        
                            if (appointment.Selected == true)  
        
                            {  
        
                                appointment.Selected == false;  
        
                            }  
        
                        }  
        
                    }

Any help is greatly appreciated,

Cheers,
