Hi!

I was wondering if it was possible to only display working hours in the scheduler instead of the whole day?

Thanks.

[Solved] iTunes-like grid

Hi guys,

I'm trying to create a grid similar to the iTunes one (in Artist mode). This is just a regular grid (no problem here), but the first colum doesn't show a row for each record, but an image for all the records that share this image (in this case, the cover image for all the tracks in an album). I have attached an screenshot to show what I'm talking about.

My question is, is it possible to implement this with GridView and, if so, how? If not, and although I know this is a bit off topic, which controls combination could I use to replicate this interface?

Thank you very much.

[Solved] RibbonBar RasSplitButtonElement behaviour

Hi All,

I've got a WinForms app with a RadRibbonBar and various groups of buttons, which all work fine ... apart from one. I've just added a Split button as I need to have additional options when "Previewing", but don't seem to be able to use the main button part as a normal Click event, without the sub-items showing, and clicking on the "Arrow" to show sub-items causes a click event on the main button as well.

Is there a way to stop the RadSplitButton from showing the dropdown of child items when clicking the "main surface" of the button (as this would be the normal action), and then ONLY show the sub-item collection when you click on the Arrow, as with Microsoft behaviour for the Ribbon Bar?

Thanks in advance,
Paul

[Solved] RTL WeekView Scheduler Bug While Navigating With UP/Down Arrows

Just reporting what I think might be a bug.
This happens in a scheduler in weekview mode with the RightToLeft property set to True (2011 Q3):
When for example the last time slot of the Wednesday is selected, if DOWN arrow is pressed, the first time slot of Tuesday will be selected. It goes back instead of going forward to the next day.
The same problem exists with the UP arrow. It goes to next day instead of previous day.

RadPanelbar containing RadGridViews

In my app, i have an radpanelbar that is populated at runtime with multiple radpanelbargroupelements (variable number, depending on the user's role), where in each of those elements, there is a radgridview.

I want to give the user the possibility to choose his layout: outlook, explorer, list,toolbox.

I works fine in outlook and list style.

When choosing explorer style, i want each radpanelbargroupelement to expand and evenly fill the available space in the radpanelbar.

The expanding works, but i cannot set the height of the contentpanel to take up as much space to evenly fill the radpanelbar.
I can this be done?

[Solved] Insert item

Hi!

I'm trying to insert a single item in a DataList, but i only get a null point exception (Object reference not set to an instance of an object..) If i "add" the same item first and then "insert" it's working, but not with insert alone...

This is not working:
lvServiceResult.Items.Insert(0, new ListViewDataItem(text + @"..."));

This is working:
lvServiceResult.Items.Add(new ListViewDataItem(text + @"..."));
lvServiceResult.Items.Insert(0, new ListViewDataItem(text + @"..."));

Any ideas?
