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~!

I am using RadPropertyGrid in WinForm. 

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.

{

        string _LogFile = "";

Hello,

is it possible to set shape name by UI? I don't see name in Settings Pane. Or can I somehow customize Settings Pane to edit name of shape?

Hi, I made my own inherited version of RadDropDownList that uses own inherited version of RadAutoCompleteBoxElement for a TextBoxElement (I wanted tokenized text items). I also got my own custom arrow that inherits RadArrowButtonElement, because I do not use the DataSource at all (only Suggest items popup is shown by this custom arrow).
This control works fine if it is used in Designer of the regular form, but when created dynamically the AutoCompleteSuggestHelper.DropDownList.Popup.Click() event does not fire (sidenote: the event AutoCompleteSuggestHelper.DropDownList.KeyDown() event works).

When the control is not created in code behind it is working completely fine. Any suggestions on how to fix it?

Hi, I have a problem with convert "Telerik.WinControls.Ui.RadDropDownList" to "System.Windows.forms.Control"

I have tried to remove and reinstall from Telerik control panel, it didn't work.

I also tried removing and reinstalling the extension within visual studio. it didn't work. 

I have found that the path c:\users\jonovoa\appdata\local\microsoft\visualstudio\16.0_8573c414\extensions\akzfqu3o.rq0 (image 2)

does not contain the folder mentioned in the error description: 

c:\users\jonovoa\appdata\local\microsoft\visualstudio\16.0_8573c414\extensions\akzfqu3o.rq0\ProjectManagement 

I just noted that I have another path with all the files: (image 3)

C:\Users\jonovoa\AppData\Local\Microsoft\VisualStudio\16.0_8573c414\Extensions\p2gdkolo.2so\ProjectManagement\Upgrade

Finally:

Visual studio throws a couple of warnings due to UNRESPONSIVE EXTENSIONS, with the following offenders:

"Progress Telerik  UI for Winforms Extension version 2021.2.505.1" (image 4)

"Progess Telerik WInforms Converter version 2021.2.505.1" (image 5)

My installed version is: R2 2021 (2021.2.511.0) (image 6)

Please help me to solve this.

Thanks,

I'm currently migrating a 160-form application to the latest Telerik framework, and I need to do some processing which is common to all forms:

- checking for, and applying a user-saved theme

- positioning the form where the user last saved it.

I could implement a method call in the _load event for each form, but I wonder if there is a better way. Maybe a kind of 'load' event which applies to all forms. Or some way to modify RadForm - whilst still making the Designer work.

Does anyone have a soltion for this which is neater than adding a method call in each of 160 forms (and remembering to do it for any ones) ?

hi

Why do I want to uncheck all the form checkboxes, but the regular checkbox is done ?!

my code is
