Display Issues with a SplitButtonElement in a RadRibbonBar - 2009.1

Greetings Telerik!

Thanks for posting the 2009v1 update. It looks like we're many steps closer towards getting my ribbon bar working as I'd hoped! There is still one issue I'm having with 2009v1, though, although there appears to be a straightforward workaround.

The common issue seems to be that if you have a RadSplitButtonElement inside a RadRibbonBarButtonGroup (as it has to be), and the SplitButtonElement's DisplayStyle property is set to either Text or TextAndImage (ie text is display, one way or another) and the ArrowPosition property is set to Bottom (all a pretty common combination), then the button displays incorrectly. The main body of the button appears to be the right width, but the arrow's width is narrower than the button proper, and any other controls in the same group overlap the button - as if the arrow's width is used for calculating the width of the control, and not the button's width (which is the correct width).

Here are steps to reproduce:

Create a Form and drop a RadRibbonBar onto it
Add a new Tab and a Group
Inside that group, add a Horizontal Button Group
Within that button group, add a RadSplitButtonElement
Change the ArrowPosition to Bottom
Run the application

You will see the text on the button bleeding outside the edge of the group, which appears to be sized to the arrow button - which is incorrectly smaller than the button proper.

For now, there are some workarounds, to get me through (keeping ArrowPosition as Right, not using Text on the buttons or setting MinSize.Width to be greater than the button should ever need to be in order to fit its text) but I'm assuming that this may be an easy one to fix, so I thought I'd let you know... as my goal is to get flexible buttons with arrows that point down!

Alternatively, is there some basic property that I'm missing which is leading me to set this up incorrectly?

Cheers,

Unexpected MaskEdit Value Behavior

Using the latest MaskedEdit control I am attempting to bind the control to a BindingSource using a List of a CustomObjects, similar to...

List<Agency> agencies = GetAgencies();
agencyBindingSource.DataSource = agencies;

Within the Agency object there is a propery called ZipCode, which I am feeding to the MaskedEdit Value propery via DataBinding

this.zipCodeMasked.DataBindings.Add(new System.Windows.Forms.Binding("Value", this.agencyBindingSource, "ZipCode", true, System.Windows.Forms.DataSourceUpdateMode.OnPropertyChanged));

I also have a navigation control on the form that allows me to move through out the list and rebinds the controls to the Current object on the list. The strange behavior occurs when moving from one object that has a zipcode to another object that doesn't. When the first object has a ZipCode it appears within the control, however when moving to the next item that doesn't have a ZipCode, the control does not clear. Instead the next item appears to have the same ZipCode as the previous item.

I have use the following rework around...

var

agencyValues = (Agency)agencyBindingSource.Current;

if (agencyValues != null && !agencyValues.Zip.IsNotNullOrEmpty())

{

zipCodeMasked.Value =

null;

}

GridView columns lose size when restored from minmized state

I have a RadGridView that starts up with the columns autosized and filled with data when the form loads. If I minimize the form, then restore it, the columns are all ~40 pixels wide and squished to the left.

Expected behavior: the columns would still be the size they were when I clicked minimize.

To the Telerik team

I have been noticing that on your RadForm there is a problem with how you get your GetDCEx. To keep it short I'll give you a short piece of code that can help you.

if

(msg.Msg != (int)WindowMessages.WM_NCPAINT)

{

return GetWindowDC(msg.HWnd);

}

int flags = (int)(DCX.DCX_CACHE | DCX.DCX_CLIPSIBLINGS

|

DCX.DCX_WINDOW );

IntPtr zero = IntPtr.Zero;

if (msg.WParam.ToInt32() != 1)

{

flags |= (

int)DCX.DCX_INTERSECTRGN;

zero = msg.WParam;

}

return GetDCEx(msg.HWnd, zero, flags);

Performance times for data-load

Hi,

I'm using RadGridView for many applications here, we are using this mostly for reporting and it works very good!

But i'm not satifisfed by the performance of the data-load. (I'm using RadControls, Q3 2008 SP1)

I'm loading the grid (with default properties) from a DataTable and these are the loading times for a grid with 12 columns:

37 rows - 843 ms
173 rows - 906 ms
319 rows - 1 138 ms

Loading with 5 columns:

35 rows - 423 ms
173 rows - 468 ms
319 rows - 530 ms

Is this to be expected ? Can I set some properties to increase the performance for this ? Is there some kind of 'EnableTurboLoad' property available ? :-)

close "x" button question

I using the code in the tabstrip tutorial to put a close "x" button on tabs and it works but is
there any way to actually destroy the tabs instead of hiding or collapsing them?

This is the code from the tutorial...

    
             Private Function newButton() As RadButtonElement 
        
             Dim radB As New RadButtonElement() 
        
             radB.MaxSize = New Size(12, 12) 
        
             AddHandler radB.Click, AddressOf HideTab 
        
             radB.Font = New System.Drawing.Font("Verdana", 6, FontStyle.Regular, GraphicsUnit.Point, (DirectCast(0, Byte))) 
        
             radB.Text = "x" 
        
             radB.TextAlignment = ContentAlignment.MiddleRight 
        
             'Alignment defines where the button will be placed on the tab 
        
             radB.Alignment = ContentAlignment.TopRight 
        
             Return radB 
        
            End Function 
        
            Private Sub HideTab(ByVal sender As Object, ByVal e As EventArgs) 
        
             Dim buttonElement As RadElement = (DirectCast(sender, RadElement)) 
        
             buttonElement.Parent.Visibility = ElementVisibility.Collapsed 
        
            End Sub
