I'm using the RadSpreadsheet control, and it's ribbon bar.

I have a simple menu, which when clicked, calls another dialog.

But the menu structure overlays the new dialog:

The menu items have gone, including the one which the user just clicked, which is good, but the outline of the ribbon is still visible.

I don't have any control over the popup window, as it comes from another application, so I can't tell it to 'bring to top'.

Has anyone else seen this ? I don't think it's specific to the RadSpreadsheet ribbon bar - i've seen the same effect on other ribbon bars.

Is there any way to avoid this ? Not a disaster, but it just looks poor. The blank space does go away, but only once everything else has completed.

Hi guys,

I am new in the C# winform design and I am trying to create a scheduler to help manager organize employee timesheet and do the punch-in punch-out. There are couple things I need some helps.

1) When I am reading the help form, I found a video about introduction of RadScheduler. https://www.youtube.com/watch?v=RHgMwE2vlsc&t=10s

But when I'm going to Blogs.telerik.com/robertshoemate I cannot find source code. Could you tell me where I can find source code? That really help me to understand how radscheduler working

2)

When I am desining Radscheduler form, The UI is always said "new appointment" and when I click "add new appointment" button the edit appointment textbox is setup in specifc form (I attached picture down below)

Could tell me where I can design this edit_appointment form? I want to change this UI. For example, change the subject Name or delete couple textbox

Regards,

Mike

Hi all,

Does anyone know if there will ever be new themes or updates to the themes?

Would like to see some new ones at some stage. Or does have any they could share?

Thanks

Hi all,

Best greetings to you all. I am currently working with a custom RadGridView in WinForms form. I am using Office 2019 Light theme along with Visual Style Builder to customize (just start as amateur). When applying the theme, I think the theme manager is overriding my code with background color and Selection Mode which was initially subscribed to FullRowSelect but later changed to CellSelect and also the application freeze as well.

I am attaching some files in the below. 

Hi there,

can I draw a polygon with stripes (lines) on RadMap?

I know how to make a plain (one color) polygon but it is possible to have stripes on the polygon?

hi

how handling error

System.ArgumentOutOfRangeException: 'Day must be between 1 and 29 for month 12.

Parameter name: day'

i try handling in key peress but show error

my cod is

public static bool CheckIsLeapYear(DateTime date)
        {
            PersianCalendar pc = new PersianCalendar();
            int year, day;
            year = pc.GetYear(date);
            day = pc.GetDayOfMonth(date);
            bool result = false;
            bool isleapyear = false;
            isleapyear = pc.IsLeapYear(year);
            if (isleapyear!=true && day>29)
            {
                result= true;


            }
            return result;



        }

When I use the excel like filters of equals, greater than, or greater than or equal to with date columns I find no matches. 

My DateTime values bound to the column have 00:00:00.0000 as the time component, like 9/30/2008 00:00:00.00000.  When I pick this date on the calendar control in the excel like filter popup it works fine, but if I pick Available Filters -> Equals (or greater than, or greater than or equal to) and enter 9/30/2008 then it does not match the 9/30/2008 00:00:00.00000 rows. 

I have tried this with FilteringMode = Date and FilteringMode = All, but it does not seem to make a difference.  It seems like equals etc. is comparing it to like 9/30/2008 00:00:01.00000 or something crazy like that. 

Is there something I can do to get these equals etc. filters working?

Using version 2021.2.615.40

I created an unbound MultiColumnComboBox and added the multi-select functionality from the how-to documentation. This works fine, but I'd now like to add some rows and set them as selected when the form loads up based on some text input. So I have gone with the below:

Imports Telerik.WinControls.UI

Public Class Form1
    Private Extender As New RadMultiColumnComboBoxSelectionExtender
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        InitCombo()

        Extender = New RadMultiColumnComboBoxSelectionExtender()
        Extender.AssociatedRadMultiColumnComboBox = combo1

        AddExtraItems()
    End Sub

    Private Sub InitCombo()
        combo1.MultiColumnComboBoxElement.Columns.Add("CaseCode")
        combo1.MultiColumnComboBoxElement.Columns.Add("Title")
        combo1.DisplayMember = "CaseCode"
        combo1.ValueMember = "CaseCode"

        combo1.EditorControl.Rows.Add("P1234", "Test Case 1")
        combo1.EditorControl.Rows.Add("A1234", "Test Case 2")
    End Sub

    Private Sub AddExtraItems()
        AddRow("T12345", "Test Case 3", True)
        AddRow("P23445", "Test Case 4", True)
    End Sub

    Private Sub AddRow(ByVal CaseCodeString As String, ByVal Title As String, Optional ByVal Pinned As Boolean = False)
        Dim row = combo1.EditorControl.Rows.NewRow()
        row.Cells(0).Value = CaseCodeString
        row.Cells(1).Value = Title

        If Pinned Then
            row.PinPosition = PinnedRowPosition.Top
            row.IsSelected = True
            row.Tag = True
        End If

        combo1.EditorControl.Rows.Add(row)
    End Sub

    Private Sub combo1_DropDownClosing(sender As Object, args As RadPopupClosingEventArgs) Handles combo1.DropDownClosing
        args.Cancel = True
    End Sub
End Class

This adds items to the list and has them ticked however items do not appear as tokens in the Combobox and if I open the combobox and tick/untick an item the application crashes and the form closes. Is there a specific way to do this? I have attached a small example project to demo what is happening.

Thanks in advance for any help!

Hello,

I have problem wit DesktopAlert control. We use it as notification popup and it works great. I can close on click all popups until I create new modal form on top of current form. Then I can close only newly created alerts, but old alerts stay there and cant be closed until modal form is closed. Is there solution to make closable all alerts at all time? Problem is that alerts can obfuscate UI of new modal form and I cant then close this form and there is no solution.

Here is sample project which simulate this problem.

Hi~!

One item of propertygrid is File Path(string). When user click the File Path element to edit, I want to show Openfiledialog.

When I use Windows default control, it works well, but when I use telerik control, it doesn't work.
