Hello,

I have downloaded the latest winform version today and launched my application.

I experienced an immediate crash while replacing a document container by a split container.

You can see the small piece of code and the insttruction which is causing the crash ....

Obviously it was working properly before upgrading ...

Can you help? I am now just stuck so a fix or a workaround would be useful...

Thanks,

Olivier D.

 

if (ctrlOutput == null)
            {
                Telerik.WinControls.UI.RadSplitContainer mainSplitContainer = null;

                ctrlOutput = new ToolWindowOutput(sbOutput);

                var Output = new Telerik.WinControls.UI.Docking.ToolWindow();
                Output.Text = "Output";
                Output.Controls.Add(ctrlOutput);

                var toolTabStrip = new Telerik.WinControls.UI.Docking.ToolTabStrip();
                toolTabStrip.Controls.Add(Output);

                if (this.documentContainer1.Parent == this.radDock1)
                {

>>>>>>>>>>>>>>>>>>>>>>>>>>>>

                    this.radDock1.Controls.Remove(this.documentContainer1); <<<< CRASH HERE

>>>>>>>>>>>>>>>>>>>>>>>>>>>>
                    // need to remplace document container by a split container
                    mainSplitContainer = new Telerik.WinControls.UI.RadSplitContainer();
                    mainSplitContainer.Orientation = System.Windows.Forms.Orientation.Horizontal;
                    mainSplitContainer.Controls.Add(this.documentContainer1);

                    this.radDock1.Controls.Add(mainSplitContainer);
                }
                else
                {
                    mainSplitContainer = (Telerik.WinControls.UI.RadSplitContainer)this.documentContainer1.Parent;
                }

                mainSplitContainer.Controls.Add(toolTabStrip);

Please use the following code snippet:    

 

Sub New()

        InitializeComponent()
        Me.RadTreeView1.Nodes.Clear()
        Me.RadTreeView1.CheckBoxes = True

        Dim node = New RadTreeNode("1") With {.CheckType = CheckType.CheckBox, .Checked = True, .CheckState = ToggleState.Indeterminate}
        RadTreeView1.Nodes.Add(node)
        node.Nodes.Add(New RadTreeNode("1.1") With {.CheckType = CheckType.RadioButton, .Checked = True, .CheckState = ToggleState.Indeterminate})
        node.Nodes.Add(New RadTreeNode("1.2") With {.CheckType = CheckType.RadioButton})
        node.Nodes.Add(New RadTreeNode("1.3") With {.CheckType = CheckType.RadioButton})
        node = New RadTreeNode("2") With {.CheckType = CheckType.CheckBox, .Checked = True, .CheckState = ToggleState.Indeterminate}
        RadTreeView1.Nodes.Add(node)
        RadTreeView1.Nodes.Add(New RadTreeNode("3"))

    End Sub

 

Workaround:

    Sub New()

        InitializeComponent()
        Me.RadTreeView1.Nodes.Clear()
        Me.RadTreeView1.CheckBoxes = True

        Dim node = New RadTreeNode("1") With {.CheckType = CheckType.CheckBox, .Checked = True, .CheckState = ToggleState.Indeterminate}
        RadTreeView1.Nodes.Add(node)
        node.Nodes.Add(New RadTreeNode("1.1") With {.CheckType = CheckType.RadioButton, .Checked = True, .CheckState = ToggleState.Indeterminate})
        node.Nodes.Add(New RadTreeNode("1.2") With {.CheckType = CheckType.RadioButton})
        node.Nodes.Add(New RadTreeNode("1.3") With {.CheckType = CheckType.RadioButton})
        node = New RadTreeNode("2") With {.CheckType = CheckType.CheckBox, .Checked = True, .CheckState = ToggleState.Indeterminate}
        RadTreeView1.Nodes.Add(node)
        RadTreeView1.Nodes.Add(New RadTreeNode("3"))


        Me.RadTreeView1.ExpandAll()
         
    End Sub

    Private Sub RadForm1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Me.RadTreeView1.CollapseAll()

    End Sub

The ItemHeight property of ListElement cannot be set at design time. ElementHierarchyEditor can set the property, but it is not serialized.

the setup is a dotNet 4.5.2 winforms application with RadGridView in virtual mode.

The exception occur when the application is left working for days (2 in this case) without any user interaction.

The application normally updates a list that is used by the gridview, the list records are added and removed continuously, the grid view RowCount is updated via a timer.

i suspect that the RowCount reported at one point in time doesn't match the list size as it is trimmed, and therfore the GetRowHeight fails as the data doesn't exist - can this be handled in the gridview - to avoid a termination of the process due to the exception ?

 

regards,

guy.

Just a request to add in a RadFontDropDownListElement item to the RadRibbonBarGroup item list in the RadRibbonBar.

I am bypassing this by manually loading in the system fonts to a RadDropDownListElement but I could see the ease and appeal of having it already available.

Release R1 2020

Recently OpenStreetMap changed their tile usage policy and require UserAgent string in the web headers for accessing tile.openstreetmap.org tiles.

https://operations.osmfoundation.org/policies/tiles/

As a result, standard open street map mode does not work - no tiles are loaded and "too many requests" error is returned from the server.

RadMap's OpenStreetMapProvider needs API (event, property or similar) for easier set up of UserAgent / Referer / other headers of web requests.

When a set of RadForms is used inside an MDI Form and are maximized, after some time, the child forms flicker continuously.

See the attached video.

The same behaviour DOES NOT happen when regular Windows Form is used.

It appears that RadControlSpy.dll isn't packaged with any of the Telerik.UI.for.WinForms NuGet packages and isn't available as a standalone package.

This request is to make the DLL available as a standalone NuGet package available on the Telerik NuGet server.

Hi,

when I select the column chooser multiple times via context menu, the column chooser dialog scales multiple times.

Reproduced here with the Telerik sample application. 150 % dpi scaling.

Backgroud

The behavior of split button makes me confused when I use split button collapsing the split panel. It locates in different position when I restore the split button by double-click. What's weirder is that double-click will make no effect when the split button located on the edge. I don't like these default behaviours.

Question

1. Do you know how to overwrite the default behaviour of split button?

2. Is there a virtual method or some event I can reimplement?

3. I want to collapse the right panel to the right side, and restore it to the initial location, and just these to behaviours. How can I do it?

Thanks!

Use case: when RadPopupEditor is opened, the focus is sent to the popup control which handles all the pressed keys. It would be added public API which provides the possibility to plug into this keyboard handling and customize the behavior.

For example, when the popup is opened, pressing Escape, closes the popup. This functionality comes from the RadPopupContainerForm.OnKeyDown which behavior can't be overridden.

Currently, only the listener can be removed for a certain popup:

    Private Sub RadPopupEditor_PopupOpened(sender As Object, e As EventArgs)       PopupManager.Default.RemovePopup(Me.RadPopupEditor1.PopupEditorElement.PopupContainerForm)
    End Sub

I'm just starting with RadGridView and trying to figure out how to create a combobox column inside my RadGridView.  I've added a column that is of type GridViewComboBoxColumn.  I've created a BindingSource that Contains the values for the combobox.  I can't figure out how to set the datasource property of the Column to use that BindingSource.  Google search says to set the datasource property but when I'm going through the "Open Properties Builder"  and I select my combobox column I don't see that property listed under advanced for the column.

Thanks

Hi,

Using the last release of RadSpreadsheet, I get an exception when the first row is hidden when scrolling with the mousewheel. Attached is a demo.
