Hi Telerik,

Trying to find trackball behavior, but I actually need to display a horizontal line, that crosses the given ScatterLineSeries  and starts at the corresponding vertical axis. (Attached an example image.)

Hello,

Is it possible to prevent RadTreeView entering edit mode when you click on a selected node?  We would still like nodes to be editable but only when the user presses F2 or when we programmatically enter edit mode.

Thanks,

Hayley

Hello,

I haven't seen this in the demos or documentation (yet?). is it possible to display bars, lines or sparklines in the cells of a pivot grid ? is this supported by a public method or property? can this be programmed? is this difficult or extensive?

thanks in advance

Telerik UI for WinForms controls used to be automatically added to Visual Studio's Toolbox during the installation process when using .NET 2.0 (up to 4.8) Framework in your project. This means that the Toolbox population relies on the Telerik WinForms version available in the Global Assembly Cache.

With the introduction of .NET Core/.NET 5 and the WinForms designer, the Toolbox configuration doesn't rely on the GAC anymore and it is not necessary to have an installation of the Telerik UI for WinForms suite. The Toolbox version depends on the installed NuGet package:
https://docs.telerik.com/devtools/winforms/core/core-toolbox-version

There is a known issue that any UserControls/ custom controls don't show up in the toolbox for a VB  project with .NET6.  Even the RadControls are not loaded in the toolbox. 

This seems to be a known issue introduced in Visual Studio 2022 17.3 only for VB project with .NET6. Microsoft are currently working on the issue and I believe that an update will be introduced with the fix: https://developercommunity.visualstudio.com/t/Custom-and-User-Controls-not-shown-in-To/10118197 

Is it possible to control only the end of task.

I mean if I don't want the user to modify the start but let him modify the end, is it possible ?

For now I'm just able to set to readOnly the entire task and I want to get control when I let the user modify the task (and which part)

Gerald

Thx

Not sure where I can submit a bug report but to replicate...

Create nodes on a RadNodeTree.

DoDragDrop on the node that is drag through NodeDragStart

When Node is dropped onto Scheduler, create the appointment.

This causes the program to flicker a lot and multiple appointments are created.

    Private Sub MyNodeTree_DragStarted(sender As Object, e As RadTreeViewDragEventArgs) Handles MyNodeTree.DragStarted
        If e.Node.Level = 0 Then
            MyNodeTree.DoDragDrop(e.Node, DragDropEffects.All)
        Else
            Return
        End If
    End Sub

    Private Sub RadScheduler1_DragEnter(sender As Object, e As DragEventArgs) Handles RadScheduler1.DragEnter
        If e.Data.GetDataPresent(GetType(RadTreeNode)) = True Then
            e.Effect = DragDropEffects.All
        End If
    End Sub

    Private Sub RadScheduler1_DragDrop(sender As Object, e As DragEventArgs) Handles RadScheduler1.DragDrop
            Dim node As RadTreeNode = e.Data.GetData(GetType(RadTreeNode))
            Dim point As Point = Me.ScheduleCalendar.PointToClient(New Point(e.X, e.Y))
            Dim schedulerCell As SchedulerCellElement = SchedulerUIHelper.GetCellAtPoint(point, Me.ScheduleCalendar)
            If schedulerCell IsNot Nothing Then
                Dim dragObject As String = e.Data.GetDataPresent(GetType(String))
                If dragObject IsNot Nothing Then
                    ScheduleCalendar.Appointments.BeginUpdate()
                    Dim ap As New Appointment(schedulerCell.Date, TimeSpan.FromMinutes(1), node.Name, "")
                    ap.AllDay = True
                    ap.BackgroundId = node.Index + 1
                    Me.ScheduleCalendar.Appointments.Add(ap)
                    ScheduleCalendar.Appointments.EndUpdate()
                End If
            End If

    End Sub

Hello,

if have derived the RadRibbonForm.

If I'm using the derived OwnRibbonForm, the RibbonBar ist locked in designer.
What I have to do?

Regards

Hi good morning.

I have made an application which uses the PivotGrid, PivotFieldList and Chartview controls to present the data in the way that an Excel pivot table and chart would.

But I am at a point where the performance of creating the graph is very low compared to Excel.

I comment on the case.

When I add one more field to the PivotGrid in the rows section, the performance to present the graph begins to be slow, in this example that I show I add the "Section" field and to graph it takes 39 seconds.

But if I add a fourth field to that row section of the PivotGrid when plotting the app crashes.

The number of records handled by the PivotGrid is currently 80,000, but with a tendency to grow, the PivotGrid has no problem loading that amount of data.

I know that reading a graph as it is seen is not practical, but the user will manipulate the fields of the PivotGrid until the required information is left, of course with filters included, but while that happens the graph must be updated, but this is not possible because the app crashes, show the image.

I did the exercise of getting the table from the database with all 80,000 records and passing it to Excel and making a dynamic table and graph and I was surprised to see that in Excel when adding the "Section" field it took a couple of seconds and when I added a fourth field, it takes six seconds, also the graph is not practical to read, but the important thing here is that in Excel it does not crash and it presents the graph, I show the image of the exercise in Excel.

Hi!

I have dataset with one table and I used it to fill RadGridView with columns.

One of the columns is foreign key (SQL Server type bigint) and autogenerated as GridViewDecimalColumn.

I do not want to make master-detail view, but I'd like to show values from another table based on this foreign key.

For example,

Table 1

id bigint

code_id_form_table2 bigint

Table 2

id bigint

name nvarchar(50)

So, I'd like to show name instead of code_id_from_table2 in the RadGridView. I know how to do it with built-in DataGridView, but how can I achieve the same result with Telerik component?
