Hi,

I am trying to do Drag&Drop as show in the Telerik documentation (see https://docs.telerik.com/devtools/winforms/controls/gridview/rows/drag-and-drop).

I tried to implement it in three different ways:

1) after reading the doc, I downloaded the code and build it with VS2022. This code uses .Net Framework 4.6.1 and works exactly as expected.

2) Then, I tried to add it to my current project using .Net 6 and the current Telerik Library. I did it both in the form where it should be used and in a dedicated form with the exact code provided. In both cases, I have the 'strange' behavior that the drag works but as soon as the grabed row is movingout of its origin,  a "no entry" sign is shown both in some area of the initial grid view and everywhere in the destination one (see picture).

3 Then I tried to do it in a brand new .Net 6 project to dismiss a potential setup in my project. In this third one evrything compile and run nicely, BUT there is absolutely no drag and drop behavior.

I attached this last project, but it is really exactly the downloaded code.

So can someone explain what is wrong in this code or my way to use it ?

Many thanks

Hi.

I'm trying to draw a specific graph using RadChartView.

However, I couldn't find a way to remove the border line, which is marked with a red arrow in the attached image.

The background color must be Transparent.

Please tell me how to remove only those lines.

I'm following the example from   https://www.telerik.com/forums/object-bound-hierarchy#711007, which describes how to create an object-based hierarchy. An excellent example.

I'm now trying to modify that example to look how I want, and I've done everything apart from the critical bit - adding the row of 'child' data.

For a normal row, I would do:

 Dim gvdi As New GridViewDataRowInfo(myGrid.MasterView)
        With gvdi
            .Cells("name").Value = t.name
            .Cells("status").Value = t.status
            .Tag = t '...plus any other columns I need

        End With

The example uses the simpler constructor for a new child row, like:

                childTemplate.Rows.Add(t.id, tt.name, tt.status) '....where 't' is my object.

This also works fine

But now I'd like to use the first style of constructor for the child row, and I can't work out how to do it.

When I use the first bit of code, the runtime complains that it's not a GridViewHierarchyRowInfo, so I changed it to be:

 Dim gvdi As New GridViewHierarchyRowInfo(myGrid.MasterView)
               'With gvdi
                   .Cells("name").Value = tt.name
                   .Cells("status").Value = tt.status
                   .Tag = tt
               End With

...and that doesn't work either. Is it the GridViewHierarchyRowInfo(myGrid.MasterView) which is wrong?

Any ideas?

Thanks

I'm currently working on a project where we are using a RadDiagram to dynamically display and plan a distribution hall. Here we are using different elements/shapes in the diagram to represent storage shelves and spaces/spots in those shelves. We want to draw these shelves and their spots either horizontally from left to right or vertically from bottom to top. We want to do this by first drawing the shelve and its spots horizontally and then rotate the shelve using a custom RotationService, that rotates the shelve group programatically. This however has an unwanted side effect, which can be inspected in the provided demo app and below:

The rotation via the custom RotationService appears to move the shelve in the diagram to a "random" position depending on the RadDiagram zoom and scroll position. So a shelve can be drawn and rotated as expected in the first initialization of the diagram.

Initial Diagram creation:

If the diagrams zoom level and scroll position isn't changed a shelve can be selected and rotated using the switch button. This also works as expected.

Shelve rotation without zoom:

If however the zoom of the diagram is changed or the scroll position is changed, following a rotation of a shelve or the redraw of the whole diagram using the refresh button, the vertically rotated shape is moved to a differen position.
If the rotation of the shelve is repeated multiple times the postion of the rotated shape appears to migrate to a point in the diagram. If the shelve reaches this point it will start to rotate properly again, without further change in position.

Shelve rotation with zoom:

Refresh with zoom and different scroll positions:

As seen above the rotated shelve is drawn in different positions each time the diagrams zoom or scroll is changed. Is this due to a wrong implementation of the RotationService as seen in the Demo_Project or is it due to a bug?

Hello, it's me.

I'm modifying the Fluent theme. The button and other controls that use some of the same elements (e.g. the scroll "thumb") has a sort of "glow" with the mouse cursor along with border highlight and a white ring when pressed. Where can I change this? I removed pretty much every repository item for all elements/states besides text and fill but it's still there:

Hi,  As I understand if I bind the Appointment dataset to an MS Access database as in the Telerik tutorial sample. If I update an Appointment in one app, all Appointments in other apps within the LAN would be updated. How about if I start an app using Remote Desktop, would Appointments in the remote desktop app be updated as well.

Thanks

Hello,

I'm looking for the best approach to store a radgridviews filterdescriptors in a db, so that the users could for instance use a dropdown menu to select and save their favourite filter settings. I'm already using the save/load layout funktionality which works great but I would prefer a way to only store the filters.
Any pointers and suggestions is greatly appretiated.
Thanks

Hi Telerik!

I use the following code to open a new form in a tab. however, when I want to open a different form in another new tab, it does not open with a focus, but rather, I have to click on that tab to see it

If gF_bFormAbierto("frmProd") = True Then
            MsgBox("frm is open")
        Else
            RadDock1.Visible = True

            Dim childForm As frmProductos = New frmProd()

            childForm.MdiParent = Me
            childForm.Show()
End If

image example: the one I mark with a red arrow is the new form that I opened
