I use an unbound radgridview. After initialization of the columns i have an empty radgridview.

When i now call radgridview1.MasterGridViewTemplate.BestFitColumns( );

then the column header is ignored in the calculation of the best size for the columns and all columns are shrunken to a few pixels.

Kind Regards,

Ramius

RadPanelBar no scrollbar

Previously in the Q2 2009 release on a RadPanelBar filled with RadPanelBarGroupElement and RadToggleButtons underneath the GroupElements occasionally the scrollbar would disappear, a simple work around that I told my end users to do was click the top most RadPanelBarGroupElement and it would appear again.

Now in the Q3 2009 Beta, that workaround doesn't work, is there something that changed to cause this not to work? Even better, how can this be fixed for good so the workaround isn't necessary? Thanks.

RadDock - Dynamically adding UserControls with autoscroll

How do I get this to work? I'm dynamically adding a UserControl to the Dock control, and I can't seem to get the docked window to get scrollbars to show up when it is resized.

    
            CSUserControl itemControl; 
        
                        if (typeof(CSUserControl).IsAssignableFrom(ucType)) 
        
                        { 
        
                            itemControl = (CSUserControl) Activator.CreateInstance(ucType, parameterList); 
        
                        } 
        
                        else 
        
                        { 
        
                            UserControl item = (UserControl)Activator.CreateInstance(ucType, parameterList); 
        
                            itemControl = new CSUserControl(); 
        
                            itemControl.Controls.Add(item); 
        
                            item.Dock = DockStyle.Fill; 
        
                        } 
        
                        Size size = itemControl.Size; 
        
                        //Hook up events 
        
                        itemControl.WindowChangeRequested += documentPane_WindowChangeRequested; 
        
                        itemControl.WindowOpenRequested += documentPane_WindowOpenRequested; 
        
                        itemControl.WindowCloseRequested += documentPane_WindowCloseRequested; 
        
                        itemControl.AutoScroll = true; 
        
                        HostWindow host; 
        
                        if (dockPosition == DockPosition.Fill) 
        
                        { 
        
                            host = _dock.DockControl(itemControl, dockPosition, DockType.Document); 
        
                        } 
        
                        else 
        
                        { 
        
                            host = _dock.DockControl(itemControl, dockPosition); 
        
                        } 
        
                        host.Text = documentName; 
        
                        host.Name = documentName; 
        
                        host.CloseAction = DockWindowCloseAction.CloseAndDispose; 
        
                        host.AutoScroll = true; 
        
                        host.TabStrip.AutoScroll = true; 
        
                        //host.TabStrip.MinimumSize = itemControl.MinimumSize; 
        
                        //host.MinimumSize = itemControl.MinimumSize; 
        
                        DockTabStrip strip = (DockTabStrip)host.TabStrip; 
        
                        strip.SizeInfo.AbsoluteSize = size; 
        
                        _dock.ActivateWindow(host);

CSUserControl is simply a wrapper around the standard UserControl that gives me some extra functionality.

I've gotten it SORT OF working by using the commented out lines above - when I set the TabStrip AutoScroll = true and the minimum size as well, then the scrollbars show up. BUT it's terrible in implementation - the tabstrip randomly disappears or repeats itself, scrollbars show up when they're not supposed to be, scrolling around wrecks the tabstrib.

How am I supposed to be doing this?

expression 2 as result of expression1

Hi
I have a radgridview which has a column whose value is set by an expression:

Me.StockGrid.Columns("Total").Expression = "(Qty) *" & CInt(Me.radtextbox1.Text)

I want to use the result of the expression to populate another column in the same grid.

Me.StockGrid.Columns("req").Expression = "(Total – Available)”

The result is always nothing although the total column value calculated by the first expression has a value and available has a value. Is this type of calculation valid?

Regards
joe

Empty gridview takes 5 seconds to show up + Hierarchical subproperties

Hello world,

I am discovering Telerik and I am pretty impressed so far. However, two problems have arisen:

1. Why does it take 5 seconds to show a simple form with just an empty Gridview inside? With the standard datagridview, it is instantaneous. Am I missing a point? I can't believe everyone who uses the Gridview has to endure waiting for 5 seconds even for empty objects.

You can easily reproduce this problem (just create two forms, one with the rgv and one without, launched from a third one). No need to set up any properties to the rgv to see the low display speed.

I tried to search on the forum for similar issues but Murphy's law is there for me: as the two links I have found are not working!

WinForms Controls - GridView Forum - Initializing slow

WinForms Controls - GridView Forum - Performance to open

... why just opening the window is very slow? with 4 controls of telerik, it takes 3
or more seconds... Imagine 10 controls!! thanks!! Reply. Telerik Admin. ...

http://www.telerik.com/community/forums/winforms/gridview/performance-to-open.aspx

2. When do you intend to implement support for subproperties in the hierarchical view? This is really a must have. I have found forum posts dated 2 years back and still no support for this feature... Is it on the roadmap somewhere? Is there a workaround better than building a virtual database (with plenty of IDs to link the objects together)? For your reference, the latest forum post I found on the subject was this one:

Thanks a lot for your help!

How to disable the color change of the form when focus is changed to another form

Hello,

I cannot find where I have to modify the style of the RadForm to disable the fact that the color (of the title bar especially) changes (it becomes lighter, with Office2007Black theme) when the form loses focus (if we switch from one form to another).

Any direction would be more than welcome!

Thanks,

Erwin

Gridview TabbedChildViews

In the RadControls for Winforms Q3 2009 Beta Demo Application in the gridview TabbedChildViews Demo:

When i change the Tabs Position to left or to right then only two tabs ("Details", "Orders") are displayed and the third tab "Perfromance" is not displayed. When there is not enough space to display all tabs at a position there should be a scrollbar or something like this which should auotmatically be displayed so all tabs could be reached.

Kind Regards,

Ramius

[Solved] Continuing Problems with Unbound GridView

Hi,

I am struggling, after some days of effort, with a trivial implementation of an unbound grid.

Scenario: I have an unbound data object which I am using to populate an editable grid. When the user clicks on the "Add new row" I trap the DefaultValuesNeeded event and populate the grid cells with the default data required for that row. One of the columns is a calculated primary key, which I calculate and provide during the DefaultValuesNeeded event. (Previously I tried using the Row .Tag property but this has a similar problem to that described here).

1) The default values supplied are not visible in the row being edited.
2) When the CellEndEdit event fires, I want to copy the data from the edited cell into my underlying business object. However none of the default values I set for the row are available in the row Cells collection (including, unfortunately the primary key for the newly added row).

How can I use RadGridView to maintain an unbound list of data which has a calculated primary key, and default values ? I am really struggling with this, as it seems to be a really common thing to want to do ?

It would help if I could find a clear list of the events which fire when a row is added, in what order, and what they are intended to do - I may be missing something in the online help, but there doesn't seem to be a clear description. Irrespective of this, it seems that the magic "Add new row" feature is pretty broken if I cannot address the cells on the row during the CellEndEdit event ...

Frustrated.
Phillip
