[Solved] Why is some of my XAML code dim?

(I'm not sure if this is the correct forum to post this question in or not. I'm seeing this behavior in the XAML view, so I suspect that I should post it here.)

I've got the DevCraft Complete suite. I suspect that it's effecting the display of code, perhaps its the JustCode piece; I'm not sure. What I'm seeing is some code in the XAML view looks fine, whereas other code is dim, almost to the point of being translucent. I've noticed this in both VS 2012 and VS 2013.

What is causing this? And what does it mean?

Sorting among groups in RadGridView control

Dear Ad,

I would like to ask you a question that is about Sorting among groups in RadGridView control.
Look at the attachment.
1) when column is not grouping, I CAN sort size basing on Description then Length. (multi-criteria sorting).
2) when column is grouped by Size, a box of Size at grouping area permits users to sort among group. The problem is; that sorting based on Caption/String of size.
The picture is showing 2x2 > 2x14 but actually I want 2x14 > 2x2 in this case.
I dig in this a lot, such as rebinding SortDescriptor at the event of grouping but looks like group-sorting is run at the last and noway to cancel it.
I called e.Cancel = true already, but this action seemed to make group-sorting disable like loosing this function on UI.

Please help me on "multi-criteria group sorting".

Thanks
Hao

How to make RadExpander fully customized

Hi team,
I've learned the Template Structure of RadExpander and know the header is just a RadToggleButton. Now I want to make the header sort of a container which contains other controls and also a button representing the functionality of the original RadToggleButton. I have no idea to do that? Any demos?

Recurrence Question

I am looking at ScheduleView to see if it can fit some of my scenarios. And here is some scenarios I stuck with:

1) occur 5 times a day on every 2 days

2) occur every 4 hours a day on every 2 days

Could I know how can I set this recurrence pattern on code behind?

Moreover, I have tried a RecurrencePattern like the following:

            pattern = new RecurrencePattern()
            {
                Frequency = RecurrenceFrequency.Daily,
                HoursOfDay = new int[] { 4, 8, 12, 16 },
                Interval = 2,
            };

and I suppose, on day 1 , the events occur at 4am,8am,12pm and 16 pm. On day 2, no event occur. On day 3 , events occur like on day . On day 4, no event occur. But turn out, events occur on Day 2,Day 4 as well. Am I misunderstanding the parameter "Interval"? How can I set in this case if I want to occur on every 2 day?

[Solved] Prevent drop if outside destination

I'm using DragDropManager to reposition ListViewItems within a single ListView. How can I prevent a ListViewItem from being dragged out of the ListView? RadDragAndDropManager used to have a DragQueryEvent, but I cannot find a similar event with the new DragDropManager framework.

align right not working

Greetings.

In our web application we implemented the Telerik RadEditor.
Now we have a problem exporting a document to word.

When we export the document, the text aligned to the right, keeps normal (from left to right).
However if we align the text with spaces to the right, the format keeps well.

Any idea what might be going on for right alignment not working? Don't know if it helps, put left align and center align are working and are well exported.

Regards.

recursive loading data when scrolling (virtualCollection)

Hi,
I use a VirtualCollection binded to a RadGridView (Version 2015.1.225.45 framework 4.5.1 )
My scenario is : when i click on the button move last VirtualCollectionPays.MoveCurrentToLast(); the scrollbar of gridview move to last position and when i click on the button move fist VirtualCollectionPays.MoveCurrentToFirst(); the scrollbar of gridview move to fist position .

Error : when i move to the last and come back to first position the loading event in virtual collection make a recursive call and load all Items in the database .
I use a plain wcf services not rest nether data services .
i use an async methode in the loading event .

//

public async void LoadData()

{

VirtualCollectionPays = new VirtualQueryableCollectionViewExtended<Pay>() { LoadSize = SizePage };

VirtualCollectionPays.ItemsLoading += VirtualCollectionPays_ItemsLoading;

PayDataPage datapager = null;

var slowTask = Task.Run(() =>

{

datapager = _dataProvider.GetQueryableLazyPay(SizePage, position, PayFilterDescriptor, PaySortDescriptor, PayGroupDescriptor);

});

await slowTask;

VirtualCollectionPays.VirtualItemCount = datapager.TotalCount;

VirtualCollectionPays.Load(0, datapager.DataItems);

}

async void VirtualCollectionPays_ItemsLoading(object sender, VirtualQueryableCollectionViewItemsLoadingEventArgs e)

{

BusyIndicatorGrid = true;

try

{

PayDataPage datapager = null;

ItemsLoading = Task.Run(() =>

{

datapager = _dataProvider.GetQueryableLazyPay(SizePage, e.StartIndex, PayFilterDescriptor, PaySortDescriptor, PayGroupDescriptor);

});

await ItemsLoading;

VirtualCollectionPays.Load(e.StartIndex, datapager.DataItems);

BusyIndicatorGrid = false;

}

catch (Exception ex)

{

string mg = ex.Message;

}

when selected change of gridView the scrollbar change position

void radGridViewPay_SelectionChanged(object sender, SelectionChangeEventArgs e)

{

var VMListePay = this.DataContext as VMListePay;

radGridViewPay.ScrollIndexIntoView(VMListePay.VirtualCollectionPays.CurrentPosition);

}

same problem when i change SelectionChanged with PropertyChanged

void VirtualCollectionPays_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)

{

var VMListePay = this.DataContext as VMListePay;

if (e.PropertyName == "CurrentPosition")

{

if (VMListePay.VirtualCollectionPays.CurrentPosition >= 0)

{

radGridViewPay.ScrollIndexIntoView(VMListePay.VirtualCollectionPays.CurrentPosition);

}

RadGridView - UI Automation

I've trying to test automatically a RadGridView using UI Automation / Coded UI from Microsoft. Everything is fine using the RadGridView built for .Net 3.5 SP2. Each cell is detected and I can click into it to modify the cell's value.
However, we have switched to .Net 4.0 and the corresponding Telerik version. Unfortunately, I'm facing the problem that I am just able to click into the cells of the last rows.

Any suggestions how to fix this problem?
