Hi,
I have a requirement for subtotals on a gridview with databinding and grouping enabled (One extra row at the bottom of each grouped section with totals for all numerical fields).
I could of course adapt the DataTable, but it seemed more performant to me if I could use the GroupingChanged Event and just add the needed rows in the gridview.
But obviously, since I am writing this :-), I ran into some troubles trying to achieve this:
- The GroupingChanged event does not fire, even if it seems to be properly defined in the designer class
- I found out about the nested rows in the grouping structure and was able to get the code in place for calculating the subtotals row, but I cannot figure out how to add this new row without touching the underlying DataSet. Apparently it's just a bit more complicated than adding cells -and I am a bit confused about the relation between the row.Cells, row.rowInfo and row.Rows properties-.
- I will also be trying this for horizontal totals (1 per row), which is pretty easy to do on a data level, but if you have any remarks on how to do it on clientside, I am all ears :-)

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Anybody can help me?

thanks.

Not showing a Shaped form contents while dragging

I am using a shaped form for a multimedia application where I do not want to show the window's content while dragging. Is there a way to do this? I have it turned off in the desktop properties and only a form with RadControls will still show its contents while I'm dragging the form around the desktop. Also is there an event in the form or .NET it self to detect when the form has finished moving, like "onMoved".

Please let me know how to turn "Show window contents while draging" off.

Thank you

Suggestion

Hi,
Your controls are very good and you could make some of them for Mobile Devices - Compact Framework, like Charts, Grids, Trees, Tabs, Buttons, etc.
Good work.

Animation Effect for controls

After reviewing your WinControls example application, I would like to try to reproduce some of the functionality that is used if possible.

When viewing individual control examples, i see that you have a "zoom and drop" animation effect on the following buttons: "Load Theme", "Theme Builder", "Control Spy". Is this possible with your RadButtons today?

In addition, you have another effect on your "Launch Example" effect that slides down and drops into position.

Are these animation effects avaiable today for RadControls... specifically buttons to draw users attention to new buttons?

Save DockingManager content

Hi,
I need to save/load the structure and dockpanels of my dockingmanager without using savexml and readxml.

I need some code like this:

save panels:
For Each d As DockPanel In DockingManager1.DockingSites(0).ManagedDockables
comando.Parameters.Clear()
comando.Parameters.Add(New SqlClient.SqlParameter("@Codigo", i))
comando.Parameters.Add(New SqlClient.SqlParameter("@CodigoVista", vista))
comando.Parameters.Add(New SqlClient.SqlParameter("@Indicador", i))
comando.Parameters.Add(New SqlClient.SqlParameter("@DockPosition", d.DockPosition))
comando.Parameters.Add(New SqlClient.SqlParameter("@Altura", d.Size.Height))
comando.Parameters.Add(New SqlClient.SqlParameter("@Largura", d.Size.Width))

comando.CommandText = "INSERT INTO TbPaineis (Codigo,CodigoVista,Indicador,DockPosition,Altura,Largura) VALUES(@Codigo,@CodigoVista,@Indicador,@DockPosition,@Altura,@Largura)"
If sqlConn.State <> ConnectionState.Open Then
sqlConn.Open()
End If
comando.ExecuteNonQuery()

i += 1
Next

load panels:

For Each d As Object In DockingManager1.DockingSites(0).ManagedDockables
DockingManager1.DockingSites(0).Remove(d)
Next

For Each dr As DataRow In dsVistas.Tables(0).Rows
Dim dock As New DockPanel
dock.Tag = dr("Codigo")
dock.Text = dr("Indicador")
DockingManager1.SuspendLayout()
dock.Size = New Size(dr("Largura"), dr("Altura"))
DockingManager1.ResumeLayout()
DockingManager1.SetDock(dock, dr("DockPosition"))
Next

I tried this code but the structure loaded is different from the saved one.
What is missing?
Thanks in advance.

Check all nodes

Hello,

I want to check all the nodes in my treeview. I searched if a method to do it existed but I haven't found anything.
Should I do a recursive loop on my node collection to check all the nodes of my treeview ?

I know it's the first version of the WinForm Treeview but a method to check or uncheck all the nodes could be useful.
There is also some nice methods available in your ASP.NET RadTreeView that should be included in the WinForm version like the GetAllNodes method. It's only an example I haven't listed all the difference.

I'm waiting for your answer and feedback
Best regards
