Hey telerik,
My grid's external spinner (RadBusyIndicator) won't work when grouping the grid. It works only when loading data.
Here is some sample code illustrating my scenario:
<
telerik:RadBusyIndicator
Name
=
"busyIndicator"
IsBusy
=
"True"
DisplayAfter
=
"0"
>
<
telerik:RadGridView
Name
=
"RadGridView"
ItemsSource
=
"{Binding View}"
IsReadOnly
=
"True"
Style
=
"{StaticResource VitorStyle}"
AutoGenerateColumns
=
"False"
>
private
void
Window_Loaded(
object
sender, RoutedEventArgs e)
{
((ViewModel)DataContext).Load(complete);
var view = (DataContext
as
ViewModel).View;
view.ItemsLoading += View_ItemsLoading;
view.ItemsLoaded += View_ItemsLoaded;
//the spinner wont work for the grouping.
//this.RadGridView.Grouping += RadGridView_Grouping;
//this.RadGridView.Grouped += RadGridView_Grouped;
//this.RadGridView.GroupRowIsExpandedChanging += RadGridView_GroupRowIsExpandedChanging;
//this.RadGridView.GroupRowIsExpandedChanged += RadGridView_GroupRowIsExpandedChanged;
}
//private void RadGridView_GroupRowIsExpandedChanged(object sender, Telerik.Windows.Controls.GridView.GroupRowEventArgs e)
//{
// this.busyIndicator.IsBusy = false;
//}
//private void RadGridView_GroupRowIsExpandedChanging(object sender, Telerik.Windows.Controls.GridView.GroupRowCancelEventArgs e)
//{
// this.busyIndicator.IsBusy = true;
//}
//private void RadGridView_Grouped(object sender, GridViewGroupedEventArgs e)
//{
// this.busyIndicator.IsBusy = false;
//}
//private void RadGridView_Grouping(object sender, GridViewGroupingEventArgs e)
//{
// this.busyIndicator.IsBusy = true;
//}
//B)
private
void
View_ItemsLoading(
object
sender, VirtualQueryableCollectionViewItemsLoadingEventArgs e)
{
this
.busyIndicator.IsBusy =
true
;
}
private
void
View_ItemsLoaded(
object
sender, VirtualQueryableCollectionViewItemsLoadedEventArgs e)
{
this
.busyIndicator.IsBusy =
false
;
}
public
class
ViewModel
{
public
VirtualQueryableCollectionView View {
get
;
set
; }
Controller controller;
public
ViewModel()
{
controller =
new
Controller();
}
public
void
Load(
bool
complete)
{
//G the virtual queryable collection. this is the Key Class telerik grid needs to perform the Infinite scrolling. or virtualization.
View =
new
VirtualQueryableCollectionView(controller.GetList(complete)) { LoadSize = 10 };
}
}
This spinning issue has been troubling me for quite some time by now.
It won't show on grouping, sorting and filtering.
please send a light
Thank you!
Hi,
I'm creating RibbonView with an ApplicationMenu, I have several items, and it structured in 2 levels.
The 2nd level can has a lot of voice, these voices exeeds over ApplicationMenu area.
I tryed to value ApplicationMenu.Content with Grid sized, but ApplicationMenu area does not expand.
How should I go about doing this?
Hi to all,
I create a docking, when add new usercontrol, I insert a new RadPane that contains the usercontrol selected, ok.
After I add other one usercontrol, docking activates my last usercontrol, ok.
In my 2nd usercontrol I have gridview, apply filter by filtersearch.
Click on 1st usercontrol (first radpaneheader),
after that, click again on 2nd, my filter is cleared, and gridview reload all data.
Can I disable this behavior?
I am currently upgrading our customer Aplication from Telerik UI for WPF version 2010.3.1314 to Telerik UI for WPF version 2016.2.613.
Currently I am upgrading RadScheduler to RadScheduleView in XAML file.
I cannot run the program yet because of a large number line of code in project.
Please help me to review my modify source code, expecialy how to migrate MonthViewScrollBarVisibility="Collapsed" and alendarVisibility="Visible".
Thanks,Liem.
Hi,
RadGridView behavior after update/insert row is different
between NewRowPosition="Top" and NewRowPosition="Bottom".
When position is defined "top", after saving the scroll is on
the same position as before saving. However, when the position is defined "Bottom", after saving
it scrolls to top.
Workaround with ScrollIntoView() is not useful in my case, because I may have
many rows updated.
How can I achieve the same behaviour as NewRowPosition="Top" after saving?
Thanks

Hi,
I am new to using Telerik Framework. I am trying to write automated tests for a WPF application that we have, but I keep getting a null reference exception when I try and use the code described in this page http://docs.telerik.com/teststudio/testing-framework/write-tests-in-code/silverlight-wpf-automation-wtc/wpf-ui-automation.
This happens in the line that is launching the application 'WpfApplication foo = myManager.LaunchNewApplication(@"C:\Users\e-ddcr\Documents\GAV\2.0\gav-app\PokeMoon\PokeMoon.Startup\bin\Debug\PokeMoon.Startup.exe"); '. Unfortunately the error does not seem to give me very much to go on, and I could not find anything online that helped resolve the issue.
Below you have the details of the error and my code. Any help would be hugely appreciated.
Many thanks,
