RadioButton in CommandBar

Hi,

I have just upgraded my RadControls for WinForms from Q1 2010 SP1 to Q1 2011.

Since I have been using RadToolStrips in my project, I got warnings telling me to use CommandBars instead of RadToolStrip.

So, I tried switching all the RadToolStrips to CommandBars, but I noticed the only way to add RadioButtons in a CommandBar is to use CommandBarHostItem. However, I couldn't put more than 1 RadioButton in a CommandBarHostItem. I had to create 1 CommandBarHostItem for each RadioButton, and if I do it that way, multiple RadioButtons can be selected at one time, which defeated my purpose of using RadioButtons because I want only one button in a group of radio buttons can be selected at one time.

Are there any solutions for my case?

Thanks

Change color of button on the alert.

I add buttons to my alerts so that the user can take some action if they want.

I personally do not feel these buttons are easy to see. They look like text. I want something that stands out more.
How can I change the color of the button?

I tried to set the backcolor and the BorderElement.BackColor of my RadButtonElement.

Something is overriding my settings.

Combine controls into one image to load into RadCarousel

This question may belong in a different WinForms controls forum. If so, I apologize.

Ultimately, I am wanting to show a carousel full of RadGridViews, but for performance's sake I am converting the RadGridView's into RadImageItems to be loaded into the carousel.

I'd like to be able to put a label above the RadGridView as a title for the grid. So far I've tried adding a RadLabel and RadGridView to a RadItemsContainer, and then using the "GetAsBitmap" function to no avail.

RadImageItem image1 = new RadImageItem();

image1.Image = rl.RootElement.GetAsBitmap(Brushes.White, 0, new SizeF(1, 1));

rl.RootElement.GetAsBitmap(Brushes.White, 0, new SizeF(1, 1));

RadImageItem image2 = new RadImageItem();

image2.Image = grid.RootElement.GetAsBitmap(Brushes.White, 0, new SizeF(1, 1));

RadItemsContainer ric = new RadItemsContainer();

ric.Items.Add(image1);

ric.Items.Add(image2);

RadImageItem image3 = new RadImageItem();

image3.Image = ric.GetAsBitmap(Brushes.White, 0, new SizeF(1, 1));

image3.ImageKey = imageKey;

(rl = previously declared RadLabel, grid = previously declared RadGridView)

Thanks,

Rob

Formatting Summary Row while grouped

Hi All,

i have the following code to convert a integer value (seconds) to double and i wish to oput it like 00:10:15 (615 seconds) in my summary row.

Private Sub rgvWechselProtokoll_GroupSummaryEvaluate(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GroupSummaryEvaluationEventArgs) Handles rgvWechselProtokoll.GroupSummaryEvaluate

If e.Parent Is Me.rgvWechselProtokoll.MasterTemplate Then

Dim fulltime As String

fulltime = Date.FromOADate(CDbl(e.Value) / 86400)

e.FormatString = String.Format("Gesamtzeit = {0:T}", fulltime)

End If

End Sub

This is working while m grid is not grouped.

I want to have the same formatting when grouped. Currently my code looks like this

Me.rgvWechselProtokoll.Columns.Add("Sekunden")

Me.rgvWechselProtokoll.Columns("Sekunden").IsVisible = False

Dim summaryItem As New GridViewSummaryItem()

summaryItem.Name = "Start"

summaryItem.AggregateExpression = "Sum(Sekunden)"

summaryItem.FormatString = "Gesamt = {0}"

Dim summaryRowItem As New GridViewSummaryRowItem()

summaryRowItem.Add(summaryItem)

Me.rgvWechselProtokoll.SummaryRowsBottom.Add(summaryRowItem)

so that i will see my seconds as Integer. When i change my first block to

Private Sub rgvWechselProtokoll_GroupSummaryEvaluate(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GroupSummaryEvaluationEventArgs) Handles rgvWechselProtokoll.GroupSummaryEvaluate

If e.Parent Is Me.rgvWechselProtokoll.MasterTemplate Or IsNumeric(e.Value) Then

Dim fulltime As String

fulltime = Date.FromOADate(CDbl(e.Value) / 86400)

e.FormatString = String.Format("Gesamtzeit = {0:T}", fulltime)

End If

End Sub

then the formatting is also added when my summery value isNumeric, but this way seems just to be a workaround.

How to apply the same formatting from my first code block using Events or AggregateExpression and FormatString the correct way

Kind regards

How to sort using hours, minutes, seconds?

Hi

I have in my object couple columns of type DateTime. I use built in functionality for sorting. On the column header user can type date. My problem is that I can define only date, hours, minutes and seconds are always zero (take a look at the screenshot).

Is there any possibility to let the user define also hours?

Regards

Annoying RibbonBar Size Issue

Hello,

In my WinForms app, I am using a RibbonBar along with a custom resizing function. Since I use a custom resizing solution, I have noticed a bug/issue with my RibbonBar. The default RibbonBar height is 141, and I can seem to change that :S. During runtime, I add a control to the RadRibbonBarChunk. This control is of a certain size so that is causes the RibbonBar to grow in height. Since I can't seem to edit the height of the RibbonBar at design time to make everything work, I have to find some way to adjust the location/size of the control below the RibbonBar that's getting affected, or find a way to force the RibbonBar's height to be greater than 141 at design time.

Any help you can give me with this problem would be wonderful!

DockWindowClosing event issue

Hi All,

Based on this forum thread I tried to obtain the affected child window of the DockWindowClosing event :

private void raddock_DockWindowClosing(object sender, Telerik.WinControls.UI.Docking.DockWindowCancelEventArgs e)

{

//closing windows

System.Windows.Forms.Form WindowClosing;

//dockwindow

if (e.DockWindow is Telerik.WinControls.UI.Docking.HostWindow)

//can convert

if (((Telerik.WinControls.UI.Docking.HostWindow)e.DockWindow).Content is System.Windows.Forms.Form)

//save the closing window

WindowClosing = (System.Windows.Forms.Form)((Telerik.WinControls.UI.Docking.HostWindow)e.DockWindow).Content;

But, the ((Telerik.WinControls.UI.Docking.HostWindow)e.DockWindow).Content is always null.

Is there any problem in my code, or it is a bad feature?

Best regards,

Peter
