Hi,

I have a grid containing a GridViewRatingColumn (amongst other columns).

I need the grid to be read-only, and have set AllowEditRow and AllowAddNewRow properties to false on the radGridView.

None the less, the user is able to change the value of the rating field anyway. How do I prevent changing of the rating column as well?

Regards

Thomas

Hi there,

I'm using a RadScheduler with the month view as ViewType in my WindowsForms application. The main goal is the following:

I need to set the width of each appointment based on integer values. For example: I have a total (100%) of 41. It should now create an appointment with value 41 with the full width. So far so good, this is easy. But I need now two different appointments ("Open" and "Done") with a percentage width of the 41. E.g. 27 "Open", so the width of this appointment should be about 66% of the full width. Then I have 14 for "Done", which should be an appointment with about 33% of the full width. I provided an example image of how it should look at the end.

I hope you know what I mean. Is this possible?

 

I add the appointments like this:

 

schedule.FocusedDate = DateTime.Today;
schedule.Resources.Add(new Resource() { Id = new EventId(1), Name = "PlannedDay", Color = Color.LightGreen });
schedule.GroupType = GroupType.Resource;
schedule.ActiveView.ResourcesPerView = 2;
schedule.Appointments.Clear();
 
Appointment app1 = new Appointment(DateTime.Today.AddDays(2), new TimeSpan(0, 0, 5), "Total: 41 Boxes");
Appointment app2 = new Appointment(DateTime.Today.AddDays(2), new TimeSpan(0, 0, 4), "Open: 27 Boxes");
Appointment app3 = new Appointment(DateTime.Today.AddDays(2), new TimeSpan(0, 0, 3), "Done: 14 Boxes");
 
app1.AllowEdit = false;
app1.AllowDelete = false;
app1.ResourceId = new EventId(1);
 
app2.AllowEdit = false;
app2.AllowDelete = false;
app2.ResourceId = new EventId(1);
 
app3.AllowEdit = false;
app3.AllowDelete = false;
app3.ResourceId = new EventId(1);
 
schedule.Appointments.Add(app1);
schedule.Appointments.Add(app2);
schedule.Appointments.Add(app3);

In RadGridView, the user can set the string to search.

How to determine that RadGridView is searching? Is it possible to programmatically interrupt the search process?

If there are many rows in the table, the search can take quite a long time. If the user does not wait for the end of the search and closes the form with the RadGridView, an error occurs.

I use RadSpreadSheet to view xlsx stored in the database (so they need to be protected from editing). But for some worksheet, this leads to the following error:

System.ArgumentException: algorithmName
в Telerik.Windows.Documents.Utilities.Guard.ThrowExceptionIfNullOrEmpty(String param, String paramName)
в Telerik.Windows.Documents.Common.Model.Protection.ProtectionHelperBase.GenerateHashBase64(String password, String salt, String algorithmName, Int32 spinCount)
в Telerik.Windows.Documents.Spreadsheet.Model.Protection.ProtectionData.EnforceProtection(String input)
в Telerik.Windows.Documents.Spreadsheet.Model.Sheet.ProtectSheet(String password)

I cannot submit the file, as it contains confidential information. Perhaps the reason is that the worksheet contains links to other files that are not on this computer.

 

Here's a line from my program that causes an error:

 

tem.Protect("abc", WorksheetProtectionOptions.Default);

Hi, 

I'm trying to create a ribbon menu without the backstage menu (an quickaccess, and titlebar).

By setting visibility to collabsed, I can remove all I want to remove, which is great. However, even though I have hidden the backstage menu, there is still room in the UI for it, so that the first ribbon tab is drawn as if it is there. I would like for the ribbon tabs to start on the left, as if the backstage menu was never there.

How do I achieve this?

Please see the screenshot for visual clue.

Regards

Thomas

When you have a Spreadsheet  and there are n sheets on its workbook, I'd like to either get the Index of the Worksheet that is being Removed (or is Removed) or the Sheet itself when it is being removed (but when it is already removed before then I won't be able to use it to retrieve the index)

Is that possible?

The nearest event I saw was the Context Changed event of the Workbook element, but I couldn't figure it out.
