I have an issue with loading forms in the Dock

When I use MDI they load poroperly. On being told to drop the MDI overhead the forms load off to the bottm right of the screen
Please help what is wrong with the code.

MDI loader

Shared Sub dockMDIForm(ByVal mydockableform As Form)

'Check if form already in Dock

Dim hw As HostWindow = frmMain.radDockMain.GetHostWindow(mydockableform)

If Not hw Is Nothing Then

'Just show the window

frmMain.radDockMain.ActiveWindow = hw

Else

'Create a new instance of the Form & add to dock

mydockableform.MdiParent = frmMain

mydockableform.Show()

'frmMain.radDockMain.DockControl(mydockableform, DockPosition.Fill, DockType.Document)

hw = frmMain.radDockMain.GetHostWindow(mydockableform)

frmMain.radDockMain.ActiveWindow = hw

End If

End Sub

Document loader

Shared Sub dockForm(ByVal myForm As Form)

myForm.FormBorderStyle = FormBorderStyle.None

myForm.TopLevel = False

myForm.WindowState = FormWindowState.Maximized

'Check if form already in Dock

Dim hw As HostWindow = frmMain.radDockMain.GetHostWindow(myForm)

If Not hw Is Nothing Then

'Just show the window

frmMain.radDockMain.ActiveWindow = hw

Else

'Create a new document

Dim docWindow As DocumentWindow = New DocumentWindow()

docWindow.Controls.Add(myForm)

'add to Dock

With frmMain.radDockMain

.AddDocument(docWindow, DockPosition.Fill)

.ActiveWindow = docWindow

End With

RadDock, Programmatically set DockPosition

I've been playing around with RadDock and not been able to get my head around this control...

Here is my scenario( bit simplyfied):

I've got a RadDock, which I add usercontrols to:

UserControlPlugInDemo ucpid = new UserControlPlugInDemo();
DockPosition dockTo = DockPosition.Fill;
this.radDock1.DockControl(ucpid, dockTo, DockType.Document);

Then, when a user click on a button in one of these, to open a map, I add a new tab containing map with DockPosition.Right.
This works fine.

But next time I add a usercontrol, I want it to Fill(like merging Map with the others tabs), but it adds to the active DockWindow, either o the right or left.

Any tip would be apreciated!

Trying to simply load HTML String into RadRichTextBox???

OK,

What I thought would be simple is beginning to trouble me. I've read the documentation and what I gather is that you load / import the HTML formatted text into a RadDocument and then set the RadRichTextBox Document property to equal that of the RadDocument you created.

Here is my simple code.
(This code works, but what I see is not the formatted text FROM the HTML string, but I'm just seeing the HTML string itself)... (Please Help)

//HTML Import

HtmlFormatProvider msgHTML = new HtmlFormatProvider();

RadDocument tempDoc = msgHTML.Import(this.scMsg.messageText.ToString());

this.msgContent.Document = tempDoc; // msgContent is the instance of RadRichTextBox

As I said, this compiles but instead of me seeing the formatted view, all that comes up is the Actual HTML code.

Thanks and I hope someone can help,

Cedric

Backcolor of cellelement based on appointment backgroun

Hi all.

Currently I'm working on a planning module. To display the different shifts of the employees I'm using recurring appointments.

In the Timeline view I would like to color the background of the scheduler cell instead of displaying the recurring appointment. I'm trying to get this done in the AppointmentFormatting event, because that's where I have all the information I need to achieve this. But I can't figure out how to get the CellElement of that day.

So is there a way of getting a cell element for the appointment?

Treeview Drag and Drop Required first click to select Node

Hi All,

I have Treeview in my project with "multiSelect" property to true. I have enable drag and drop for my Treeview. But my issue is, before drag and drop the node I need to click the node to select unlike windows file system you can just drag and drop particular file without first selecting it.

When I take mouse hover to node (which is not selected) and push and hold the left button and trying to drag, it will just select the node and not dragging the node.

Please help me to find out what wrong with that?

Thanks

Wrapping and FontSetting in MenuItems for Startmenu

Hello,

we are just evaluating the performance of the telerik rad-controls for a rather large migration project (vb6 to VS2008, > 1.500.000 lines of code)and played around a little bit with the test version.

Concerning the RibbonbarControl:

Is it possible to automatically let the description text of a start menu item (e.g. done in excel or word) wrap to several lines?
We tried to set the font property of a start menu's sub-menuitem different to the description text, but it won't get applied (namely: Text Font is Bold, Description Font non bold). Would that be possible?

(Like it is done in Microsoft Excel, when you open the save sub-menu. You see that every menu item there is bold and the description is non bold. The description text on top of that gets wrapped if it doesn't fit in the line. This is essential behaviour for a ribbon bar's start menu, isn't it?)

Thanks,

Klaus

System Hangs and throws 'Out of Exception' Error

Hi,

We are using telerik winforms Q3 2009 SP1. The issue happens when the user continuously using the product for long hours - after 4 hours.

When they are continuously using it, the system hangs and throws 'Out of Exception' Error. All the controls get highlighted in orange color.

As it is due to memory exception error, we even tried to minimize the memory in each and every call by doing the following.

public static void minimizeMemory()
        {
            GC.Collect(GC.MaxGeneration);
            GC.WaitForPendingFinalizers();
            SetProcessWorkingSetSize(Process.GetCurrentProcess().Handle, (UIntPtr)0xFFFFFFFF, (UIntPtr)0xFFFFFFFF);
        }
        [DllImport("kernel32.dll")]
        [return: MarshalAs(UnmanagedType.Bool)]
        private static extern bool SetProcessWorkingSetSize(IntPtr process, UIntPtr minimumWorkingSetSize, UIntPtr maximumWorkingSetSize);

But, it doesn't solve the issue.

As we are in the production, we need your immediate reply on this.

Thanks in Advance.
