To reproduce: please open the attached sample project and follow the steps illustrated in the attached gif file.

Workaround: 
1. You still can scroll while dragging a row by using the mouse wheel.

2. Use the grid in unbound mode and set the AllowRowReorder property to true instead of using a custom RadDragDropService.

3. Use a custom drag and drop service:

public class CustomDragDropService : RadGridViewDragDropService
{
    public CustomDragDropService(RadGridViewElement gridViewElement) : base(gridViewElement)
    {
    }

    public override string Name
    {
        get
        {
            return typeof(RadGridViewDragDropService).Name;
        }
    }

    protected override void HandleMouseMove(System.Drawing.Point mousePosition)
    {
        base.HandleMouseMove(mousePosition);
        System.Drawing.Point location = this.GridViewElement.ElementTree.Control.PointToClient(Control.MousePosition);
        GridTableElement tableElement = this.GetTableElementAtPoint(location);

        ISupportDrag supportDrag = this.Context as ISupportDrag;
        object dataContext = supportDrag.GetDataContext();

        if (this.AllowAutoScrollRowsWhileDragging && dataContext == null)
        {
            ScrollRows(tableElement, location);
        }
    }

    private void ScrollRows(GridTableElement tableElement, System.Drawing.Point location)
    {
        ScrollableRowsContainerElement scrollableRows = tableElement.ViewElement.ScrollableRows;
        RadScrollBarElement vScrollbar = GetVeritcalScrollbar(tableElement);
        System.Drawing.Rectangle containerBounds = scrollableRows.ControlBoundingRectangle;

        if (containerBounds.Contains(location) ||
            location.X < containerBounds.X ||
            location.X > containerBounds.Right)
        {
            return;
        }

        int delta = 0;

        if (location.Y > containerBounds.Bottom)
        {
            delta = location.Y - containerBounds.Bottom;
        }
        else if (location.Y < containerBounds.Y)
        {
            delta = location.Y - containerBounds.Y;
        }

        if (delta != 0 && vScrollbar.Visibility == ElementVisibility.Visible)
        {
            vScrollbar.Value = ClampValue(vScrollbar.Value + delta,
                vScrollbar.Minimum,
                vScrollbar.Maximum - vScrollbar.LargeChange + 1);
        }
    }

    private int ClampValue(int value, int minimum, int maximum)
    {
        if (value < minimum)
        {
            return minimum;
        }
        if (maximum > 0 && value > maximum)
        {
            return maximum;
        }
        return value;
    }

    private RadScrollBarElement GetVeritcalScrollbar(GridTableElement tableElement)
    {
        if (GridViewElement.UseScrollbarsInHierarchy)
        {
            return tableElement.VScrollBar;
        }
        return GridViewElement.TableElement.VScrollBar;
    }
}

public RadForm1()
{
    InitializeComponent();
    CustomDragDropService customService = new CustomDragDropService(radGridView1.GridViewElement);
    radGridView1.GridViewElement.RegisterService(customService);
}

Stop Expanding ALL the Telerik Toolbox control groups when Visual Studio 2017 loads a project! YES, we know your there! We PUT you there.. If we need you, we know where you are! Please quit over-convoluting the toolbox menu by obnoxiously expanding all your toolbox control groups!

When I have an InlineImage in a horizontally centered paragraph, PrintPreview presents the image unevenly on the page. There should be the same space on left and right, as the page padding is the same all around. See the arrows indicated below:

I have installed the suite of controls for winforms, but I can't get them to appear in the toolbox. When I use Extension / Telerik / Telerik UI for Winforms / Launch Toolbar configurator it shows me the control options and is supposed to add them to the Toolbox, but they don't appear. If I select the Show All option then all the Telerik control categories appear, but none are enabled. So I did it manually and it remains the same.

This image shows the toolbox after using the Telerik extension Launch toolbox configurator

As you can see, no tab appears with the Telerik controls.

And if I tell it to show me all the tabs, the Telerik controls do appear, but they are not enabled, as can be seen in the following image:

 

Thanks,

Please run the attached sample project and follow the steps in the attached gif file. You will notice that the nodes are displayed multiple times.

Workaround: it seems that if the BeginUpdate/EndUpdate methods are not used in the PerformNodeMove methods, the issue is not reproducible

  1. Using a RadGriditem
  2. Set AllowSearchRow to false as default
  3. Add a RadButton or something else to toggle AllowSearchRow
  4. Toggling works as long the "x" in the search mask is not used

When the "x" is used it seems that AllowSearchRow is not set to false because the toggle button has then to be pressed twice to show up the search mask again.

Hi,

I want to extend the RadGridView control, so I do "public class TkGrid : Telerik.WinControls.UI.RadGridView {}"

How do I apply a theme to TkGrid control ? I set "ThemeResolutionService.ApplicationThemeName = "FluentDark" but this doesn't work.

 

I attached a small project where I have one TkGrid and one RadGridView. On top of form there is a dropdown from where you can change the theme

When I do this, TkGrid is not displayed with the new theme (this works for RadGridView)

 

p.s. I also added a custom Button, TkButton inherited from RadButton. When I change the theme, the look of TkButton is changed, so this is ok

Hello, I encountered a bug with PropertyGrid when an object property is null.

But it only happens when the object has a simple property, a simple list, and a complex list with a custom control.

I'm attaching a sample project.

To reproduce this bug, run the project and hit the sort button or enter any search strings.

By default, the ImagePrimitive in a ribbon button is auto sized. If you want to disable the AutoSize property of the image and specify a specific Size, the AutoSize property gets serialized in the designer, but the Size is not. This leads to missing image after reopening the designer.

After saving the changes and reopening the designer the image is missing since its Size property is not serialized:

Code snippet for reproducing the problem:

 

    Private Sub RadForm1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Me.SongsTableAdapter.Fill(Me.MusicCollectionDataSet.Songs)
        Me.ArtistsTableAdapter.Fill(Me.MusicCollectionDataSet.Artists)
        Me.AlbumsTableAdapter.Fill(Me.MusicCollectionDataSet.Albums)

        AddHandler Me.RadTreeView1.NodeDataBound, AddressOf RadTreeView1_NodeDataBound

        Me.RadTreeView1.DataSource = Me.ArtistsBindingSource
        Me.RadTreeView1.DisplayMember = "ArtistName"
        Me.RadTreeView1.ValueMember = "ArtistID"
        Me.RadTreeView1.RelationBindings.Add(New RelationBinding(Me.AlbumsBindingSource, "AlbumName", "ArtistID", "ArtistID", "AlbumID"))
        Me.RadTreeView1.RelationBindings.Add(New RelationBinding(Me.SongsBindingSource, "SongName", "AlbumID", "AlbumID", "SongID"))
        Me.RadTreeView1.CheckBoxes = True
        Me.RadTreeView1.AutoCheckChildNodes = True
        Me.RadTreeView1.TriStateMode = True
        Me.RadTreeView1.ExpandAll()
    End Sub

    Private Sub RadTreeView1_NodeDataBound(sender As Object, e As RadTreeViewEventArgs)
        If e.Node.Level = 0 Then
            e.Node.CheckType = CheckType.None
        Else
            e.Node.CheckType = CheckType.CheckBox
        End If
    End Sub

Workaround: instead of using the NodeDataBound  event, use the NodeFormatting event to hide the checkboxes for the desired nodes:

    Private Sub RadTreeView1_NodeFormatting(sender As Object, e As TreeNodeFormattingEventArgs)
        If e.Node.Level = 0 Then
            e.NodeElement.ToggleElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed
        Else
            e.NodeElement.ToggleElement.Visibility = Telerik.WinControls.ElementVisibility.Visible
        End If
    End Sub

I start a new, Winforms .Net Framework 4.7.2 project.
I add the radBarcode to the form, a sample QR code is shown.
I change the Symbology-property to DataMatrix, the sample picture of the barcode is cleared and no barcode is shown. This is also the case when I change the Symbology-property via the control smart menu/tags

And here comes the point: I always inserted my value for the barcode in the Text-property and not in the Value-property (my fault). After playing around and reading the docu I realised that I need to set the Value property. If I do this via smart menu/tag It works fine.

But why does the Value property get cleared by changing the Symbology-Property? If there could be any conflicts between different barcodes, wouldn't it be better to show some infobox, that the value is incompatible to the selected symbology?

Hi Peter,

我們在跟一個客戶討論續約問題,因為如果不續約,當下的版本是否可以一直沿用,因為這套軟體升級不會刪除舊檔案,導致很多問題出來。

 

因為客戶編輯好專案,也進行發行動作,但是安裝到電腦會發生錯誤,請問要在其他台電腦執行客戶的安裝該如何執行.

請回復技術問題.

Within the CellEndEdit event, the GridViewCellEventArgs should contain an item to Cancel/Undo which will revert the value of the cell back to the value it had when CellBeginEdit was called.

It would be great if there was also a None (ViewMode) for PageView. That means no tabs and only the container. This is especially useful if you use PageView for Single Page WinForms. Up to now I use to hide the tabs with CodeBehind.
