Dear Telerik Team,

We noticed an issue with a selection and pinned/unpinned columns in Telerik RadGridView.

Here is a detailed description of the issue:

There are several columns in our Telerik RadGridView.
The first two columns are pinned, the rest is unpinned.
When we use the SHIFT/CTRL button on a keyboard to select multiple rows and click on a concrete cell in the last selected row (the cell is in the 'Total' column - unpinned column), everything is right with the selection (attachment: Screenshot_1).
On the other hand, when we select a different concrete cell in the last selected row (the cell is in the 'Name' column - pinned column), the selection becomes wrong (attachment: Screenshot_2).

We think there is a difference in behavior between pinned and unpinned columns during selection.

Do you have any useful knowledge about the described issue?

Thank you in advance for your response.

Best regards.

Hi,

I have two mc comboboxes in my form. Making a selection on the first one activates a composite filter on the second one so the latter will list fewer items. That works fine when the user clicks on its down arrow to display the now filtered listing. But when the user starts typing on its textbox editor, the list goes away instead of doing a further search or filtering.

Is this a bug or by design?

Thank you,

Sid

Is it possible? It is always solid white for me, and cannot find out a way to chage it. Thank you.

Hi there, I have a UserControl which I load into a form. On this control is a RadGridView. Unfortunately, the automatic cell resizing does not work. Only the heading is resized. Can someone help me?

Thanks Udo

Here is my code to load the UserControl


        Dim _objektdaten As New VB_Feuerbeschau.objekte
        _objektdaten = CType(Controls("ucObjekte"), objekte)
        If _objektdaten Is Nothing Then
            _objektdaten = New objekte()
            _objektdaten.Name = "ucObjekte"
            Me.Controls.Add(_objektdaten)
            _objektdaten.Dock = DockStyle.Fill
            _objektdaten.BringToFront()
           
        Else
            _objektdaten.Dispose()
            _objektdaten = Nothing
            _objektdaten = New objekte()
            _objektdaten.Name = "ucObjekte"
            Me.Controls.Add(_objektdaten)
            _objektdaten.Dock = DockStyle.Fill
            _objektdaten.BringToFront()

           
            '_objektdaten.rgvObjektdaten1.BestFitColumns(BestFitColumnMode.AllCells)
            For Each column As GridViewDataColumn In _objektdaten.rgvObjektdaten1.Columns
                column.BestFit()
            Next

        End If

Hi,

I have some questions on RadPageView Winforms UI. How can I change the color of hamburger button and RadPageViewPage when I hover my mouse on to it ? Let say, I want to change it to #3373ba hex color.

And also, is it possible to change the dropdown arrow color for hierarchical navigation menu here ?

 

Thanks before.

Hello,

I am knee deep converting our business app over to Telerik (which is an awesome suite of tools I wish I would have gotten it sooner!) and am running into an issue with the RadListView in detail view. I really need the ItemMouseHover event to work so I can show a custom form while the mouse is over the item but for some reason it's not firing. I have tested the ItemMouseEnter and ItemMouseLeave events and they fire correctly. Is there something I am missing to enable this event?

My test code is really simple:

  Private Sub lvBusinessApps_ItemMouseHover(sender As Object, e As ListViewItemEventArgs) Handles lvBusinessApps.ItemMouseHover
        Debug.Print("Hover")
  End Sub

 

Thank you

We were using the built-in windows DateTimePicker for all of our dates, and have changed to using RadDateTimePicker, and i am having a few issues/questions.

1. We have Overrides setup on KeyPressEventArgs to trap the ENTER key which then sends a TAB - so our users can just hit enter to move to the next field instead of being required to hit tab (this works on all data entry fields except raddatetimepicker).

2. The user is required to type in the full year. We have the format set to Short. Using standard windows DateTimePicker, the user could type 22 and it would make it 2022. But, if the user types 22 now, it just puts the 22 in the year. So if the year was 2003 and you type in 22, the year now becomes 0322. We want the year to be entered as 2 digits and use the current century. How would we do that?

3. We don't want the user to be able to clear out the date completely, we want a date to be entered. Windows didn't allow this (we never set min date values). I even set the NullDate to be "1/1/1901" and that made it when i "cleared out" the date it displayed 1/1/0001.

Thanks for your help.
