Hello,

is it possible to customize the schedule view so that it displays overlapping appointments not next to each other, but in a user defined layout? Say that I have a "regular" appointment (a scheduled activity) and I also have "time preferences", which are time slots preferred (or not) for scheduling activities. I would like to display these preferences below (not next to) the activities - see attachment, where the time preference is the green rectangle, while the blue rectangle is an activity.

Since I would like to be able to resize and move both activities and preferences, I intend to represent both activities and preferences as appointments, but maybe there is another way?

Thanks

Pavel

AddDictionary has long load-time

Hi,

Using JustTrace I've determined that a window that is loaded is most time-consuming in the AddDictionary method of the RichTextBox SpellChecker. I would like to call this method in a background thread so that it doesn't hang the application. Obviously I can't use BackgroundWorker because making modifications to a UI control. So I'm after other options for preventing the window from hanging? Perhaps this question is more general than the SpellChecker forum subfolder, but the problem has started from here :)

Thanks

Select All Filter Behavior

Is there any way to detect that Select All has been checked when persisting a filter on the gridview? I would like to ignore the distinct value list if Select All has been chosen by a user.
Thanks,

Problems installing, missing dll`s

Hey there, I am running Windows 7 64 bit and I have both VS 2012 and VS 2012 installed.

When I try to run the installer for WPF controls, I get an error saying it could not find a dll needed to run. I reran the installer with logging turned on and after looking through it, the problem seems to be that the Telerik installer cannot find the dll needed to check that VS is open and needs to close. Any ideas how I get around this? I am thinking that I need to tell the installer NOT to install the VS extensions for 2010 and 2012, then install them manually within studio via the Extension Manager?

Sorry, I forgot to mention that I am trying to install Telerik controls for WPF, version 2012 Q3.. it may also be helpful to mention that I did not run into this issue for 2012 Q2.

Please help!

Adjusting filtered icon for all RadGridViews in an application

In my application I apply the Windows7 theme by setting

StyleManager.ApplicationTheme = new Windows7Theme();

in the creation of the main window.

Unfortunately it is not clear to the end-user which columns have filters on them, so I thought about styling it. I found this thread on the forum where some things are explained.

I set to work and copied DistinctFilterControl.xaml and GridViewHeaderCell.xaml from the Windows7 theme source directory and adjusted them to my satisfaction. I can apply the GridViewHeaderCellStyle to the column by using

<telerik:GridViewDataColumn HeaderCellStyle="{StaticResource CustomGridViewHeaderCellStyle}"/>

So far so good. Now I want, of course, the style automatically applied to all data columns in my application. Is it possible to tweak this into the used theme? Or would it mean I have to create a complete new theme (e.g., Windows7bis)? Or is there a way to make a custom datacolumn that has this header style automatically applied? Or...

I don't want to end up with an application with half of the columns having my new style of funnel and the rest with the original themed funnel (because I forgot to set some property).

Thanks in advance.

reverse page animation

I've downloaded and opened the example project provided by Kaloyan in reference in this link:
Page Animation in a WPF Application

I am new to WPF and Animation. I'm able to follow through the code and understand it quite a bit but I wanted the animation to do the opposite, which I got stuck on. Although Albert from the thread posted code to reverse the animation, there wasn't the same effect as the animation included in the project. The animation provided had the effect of moving right to left. Can anyone please provide me with the animation to do the opposite, please? Here again is the sample animation (right to left) taken from the code.

public void BeginRight(FrameworkElement mockItem1, Grid container, FrameworkElement newPage)

{

this.Container = container;

this.PageWidth = container.ActualWidth;

this.item1 = mockItem1;

this.item2 = newPage;

this.Container.Children.Add(this.item1);

var width = PageWidth;

var scaleFactor = 0.8;

var halfSrink = (1.0 - scaleFactor) / 2;

this.Container.Children.Add(this.mask1);

this.Container.Children.Add(this.mask2);

var scaleDownSpline = new Spline(0.504000008106232, 0.256000012159348, 0.458999991416931, 1);

var moveSpline = new Spline(0.247999995946884, 0, 1, 1);

var scaleUpSpline = new Spline(0.321000009775162, 0, 0.45100000500679, 1);

var spacing = 15.0;

this.animation = this.item1

.Animate()

.With(this.mask1)

.EnsureDefaultTransforms()

.Origin(0, 0.5)

.Scale(0, 1, 0.2, 1, 0.7, scaleFactor)

.Splines(2, scaleDownSpline)

.MoveX(0.7, 0, 1.365, (-width * (scaleFactor - halfSrink)) - spacing, 1.9, (-width * scaleFactor) - spacing)

.Splines(1, moveSpline)

.Splines(2, scaleUpSpline)

.Without(this.item1)

.Opacity(0, 0, 0.2, 0, 0.7, 1)

.Splines(1, scaleDownSpline)

.Animate(this.mask2)

.Opacity(1.35, 1, 1.9, 0)

.Splines(scaleUpSpline)

.With(this.item2)

.EnsureDefaultTransforms()

.Origin(0.5, 0.5)

.Scale(0, scaleFactor, 1.365, scaleFactor, 1.9, 1)

.Splines(1, moveSpline)

.Splines(2, scaleUpSpline)

.MoveX(0.0, ((scaleFactor + halfSrink) * width) + spacing, 0.2, ((scaleFactor + halfSrink) * width) + spacing, 0.7, ((scaleFactor - halfSrink) * width) + spacing, 1.365, 0)

.Splines(2, scaleDownSpline)

.Splines(3, moveSpline)

.Instance;

this.animation.SpeedRatio = 755.0 / width * 1.5;

this.isRunning = true;

this.animation.Completed += (sender, e) =>

{

this.TransitionAnimationCompleted(this, new TransitionEventArgs(item2));

Container.Children.Remove(mask1);

Container.Children.Remove(mask2);

RemoveVisualBrush();

Container.Children.Remove(item1);

item1 = null;

item2 = null;

};

this.animation.Begin();

}

Auto select first item

I have a RadComboBox bound to an ObservableCollection. The collection is modified and cleared pragmatically (via various user interactions).

I'm looking for a XAML friendly solution that will set the SelectedIndex to 0 when going from no items (no selection) to having items.

I've tried simply setting SelectedIndex=0 but that doesn't work. (I get no selection).

-Mike.
