Hi Support,
I have an IBindingList of objects with a boolean property that a checkbox column is bound to. Only one object in the collection can have bolSelected = true at any time which is controlled by the collection so that when bolSelected is set to true, all other items will automatically have bolSelected = false. What I am hoping to see in the grid is when the checkbox is clicked, bolSelected is set to true and other selected item in the grid has their checkboxes unchecked automatically (as the bolSelected = false for all other objects now).

Is there was a way to make the CheckBox click update the row immediately, without entering into edit mode (as can be seen by the changing of icon in the row header). I can't seem to get the CheckBox to fire the changed event, which means that the change to bolSelected isn't being propagating to the rest of the collection. What is then the best way to refresh the grid now that the collection has changed?

Thanks for your help,
Dave

RadCheckBox accessibility properties

I'm working on making our application compatible with screen reading software. We have a RadCheckBox control on a form. The control is named chkIncludeInActive, and the text is "Include inactive." When the screen reader is enabled and you hover over the control, it says "Check box include inactive include inactive." This is despite the fact that I've set the "Accessible Description" and "Accessible Name" properties on the control both to "1" (for testing purposes). If I open the Element Hierarchy Editor, and I go to the underlying RadCheckBoxElement, I see the "Accessible Description" and "Accessible Name" are both set as "Include inactive." I can override these values in the Element Hierarchy Editor, but once I open up the form in Design mode again, the defaults are back. So it doesn't seem like these changes stick. I want to be able to override these values somehow and make them stick. The version we're using is 2011.1.11.419.

MultiView for year: month header

Hi,

I have two question about RadCalendar multi-view mode, annual visualization.

What I try to do di edit each month name, on header, putting in it the counter of SpecialDays for each month. It's a company holiday calendar, so I need to show, for every month, the total working days (365 - SpcialDays.where(Date.Month == currentMonth, just for example). How I can achieve this behavior?

Second. Seems to be a problem with the control, in full year view. What happen is that if I set MinDateRange/MaxDateRange of the multi-view on values 01/01/2018-31/12/2018, and I set FocusedDate and SelectedDate on first date on interval (1/1/2018), with a layout of 2 rows and 6 columns, setting by code currentViewRow and currentViewColumn to 0/0, what I get as result is the print-screen attached. This will not happen in any other year (before 2017 and after 2018). I think the problem is due to that 22 august 2017 in today date and august month was badly placed as column/row 0-0 by the control himself.

This piece of code is what I use to set the control layout:

<code>

if (today.Year == year)

{
colForCurrentDate = today.Month <= 6 ? today.Month - 1 : today.Month - 7;
rowForCurrentDate = today.Month <= 6 ? 0 : 1;
calendar.FocusedDate = DateTime.Now.Date;
}
else
{
calendar.FocusedDate = calendar.RangeMinDate;
colForCurrentDate = 0;
rowForCurrentDate = 0;
}

calendar.CurrentViewColumn = colForCurrentDate;
calendar.CurrentViewRow = rowForCurrentDate;

</code>

Is this a bug of the RadCalendar? What I can do in order to resolve this?

Thanks in advance!

Splitter Changes Not Working Correctly in DPI Aware App

Hello,

There appears to be an issue making tool window width adjustments via the splitters in a DPI aware app. Dragging a splitter with the mouse will eventually hide the document window as the tool window makes large changes when only small changes are wanted. This can be demonstrated with a new app with a RadDock control dropped on the form. Add 2 tool windows and 1 document window. Make the app DPI aware. Run the app at 150% and try making small width changes to either of the tool windows. The tool window will make a couple of large jumps and then completely hide the document window. It also doesn't matter which way you drag the tool window as the same phenomenon occurs.

Where in designer is the Click event hiding?

I have a RadContextMenu with a half-dozen items; I cannot for the life of me find the events for menu items. I'm in the "RadItem Collection Editor", and my six menu items are listed, but I have ONLY properties (Accessibility, Appearance, Behavior, etc) on the right. There is no "Events" lightning bolt in the property editor toolbar.

There ARE events for the RadContextMenu itself, but only for "DropDownClosed/Closing/Opened/Opening". So how do I, in the designer, set the handler for a context menu's menuitem click event?

Thanks!
