Hey,

Was labbing some this morning and i come over this.

   <telerik:GridViewDataColumn Header="LogistikID" DataMemberBinding="{Binding nOrderID}" />
   <telerik:GridViewDataColumn Header="Namn" DataMemberBinding="{Binding strDisplayName}"/>
   <telerik:GridViewDataColumn Header="CareOf" DataMemberBinding="{Binding strCareOf}"/>
   <telerik:GridViewDataColumn Header="Gata" DataMemberBinding="{Binding strAddress}"/>
   <telerik:GridViewDataColumn Header="" />


If i leave one column not binded the Gridview lags like hell.

Im pretty sure i have to bind them all because i use GridViewDataColumn, but is it realy gonna lag so bad?

If i leave it empty, Shouldn't it just be ignored?

If i bind the last GridViewDataColumn it's lag free while scrolling/filtering.

Bug or Feature?

I found an old forum thread describing the problem, but its from 2009.

Within a DataTemplate I have GridView.
Within the same datatemplate I have a button where I want to do a bulk operation on the filtered set of items.
The datacontext of the DataTemplate is an INotifyPropertyChanged derived object, which provides the GridView ItemsSource.

How do I, when handling the button click, obtain the list of filtered items back from the RadGridView?

The DataTemplate is hosted within the body of a data driven RadTabControl, if it matters.

Dear Telerik team,

i'm using a RadScheduleView Control, with Appointment Templates as used in your examples/demos (works great).
Now i want to extend the show duration of a tooltip from an appointment.

Per default it's set to 5-6 seconds, but i need it at least for 20 seconds.

I read in your forum that this can be done by setting the ToolStipService ShowDuration

eg.:
ToolTipService.ShowDuration="20000"

I tried to set his in the control template of the "root" Grid, but it doesn't work.
Can you tell me how to set this property to take this effect, or is there another configuration needed ?

eg.: Horizontal Style for an Appointment


best regards

Hi,

I have a RadGridView, depending of the grid type I need, I build dynamically each columns and each aggregate functions. Each time I build a grid, at least one decimal column exist. For othe aggregate functions than SUM, it work...
 
When I assign the ItemSource to the array of objects I receive from the back-end, I receive the following message: "Aucune méthode 'Sum' sur le type 'System.Linq.Enumerable' n'est compatible avec les arguments fournis."

xaml:

<

Hello,
I am using RadToolbar with ItemsSource.
Here is code:

ItemTemplate:

When I add elements to ExtToolbarButtons collection I see normal - styled buttons.
How to use ItemsSource with  telerik - styled buttons on RadToolbar?

This code used to work with an older Telerik release (can verify the version if need be), but no longer works with the latest (RadControls_for_WPF_2012_1_0215_Dev).

Steps to reproduce:
1. Right-click and select the context menu item to add a top-level row.
2. Right-click the row and select the context menu item to add a child row.
3. Right-click the child row, and you get the exception.

TreeListViewRow.ParentRow throws an exception because it tries to do "var parentView = this.Items.ParentView;" but Items is null.

Each top-level (parent) row contains a ParentItem object with a ChildItems property, and the ChildTableDefinition is bound to the ChildItems property. Each child row contains a ChildItem object, which doesn't have a ChildItems property, so when it tries to get the child items for a child row, the collection is null. As a workaround, if I give the ChildItem class a ChildItems property and have it return an empty collection, then the exception goes away. I'm no telerik expert, but it seems strange to me that a row needs to have a non-null collection of child items in order to access the row's parent row.

Apparently you don't let users upload test projects, so here's the source:

MainWindow.xaml:

Hi,

I'm using Telerik V2011.3.1220.35 and I have a problem with my RadWindow when I set his WindowState property to Maximized.

When I set the WIndowState property to Maximized in my XAML, when my application start, my RadWindow is Maximized and it override my taskbar. 

If I remove the WindowState="Maximized" from my XAML and I set it in the OnLoaded event of my RadWIndow, my RadWindow become Maximized without hidding my taskbar.

In both situations, if I change the AutoHide porperty of my taskbar to TRUE, when my RadWindow become Maximized, I cannot get my taskbar visible just by moving my mouse at the bottom of my screen.

Thank's

When I put in NumericUpDown minimum value, and I click down button then value of binding variable becomes less then minimum, but control shows right value.
I used this code for initialize in xaml:

And this code for initializing in C#:


So, if I have value is 1 in control, then i can get 0 in variable, but control will show 1.
Please help.

Dear Telerik Team,

i have a little quest.

I Have a RadScheduleView Control, with an AppointmentDatasource, which get's the Appointments from
a Webservice.

My Problem is, that the Appointments will be loaded by to Webservice calls

Step 1. FreeBusyAppointments
Step 2. ExchangeAppointment Details

Step 1 work very well and very fast, but Step 2. needs a lot of time, because the Backendservers are very slow while fetching the data.

So my solutions ist, that i turn on a busy indicator, loading Step 1 from the Webservice, put the Appointments into the RadschedulerView,
then turn off the busy inidcator and start a backgroundworker which loads the ExchangeAppointment details. When Step 2 is finished
the Appointments will be added to the Rad Scheduleview.

This should give users the possibility to see and user the radscheduleview before all appointment details are loaded.

That's the plan.

The Problem is, that after i turn of the busy indicator and starting the backgroundworker,
i see the freebusy appointments in the radscheduleview, but the busy indicator is also stil shown,
but it hangs up (including the InternetExplorer) until all Appointments from step 2 are loaded and filled into the radscheduleview.

I can easily reproduce this with filling some static Appointments in the RadScheduleview while blocking the Backgroundworker process with a 

System.Threading.Thread.Sleep(xxxx);

Hi,

I have problems to use print-method in RadRichTextBox control. E.g when I dynamically load RadRichTextBox to the visual tree and then set the document. This throws an null exception when I call the Print-method.


CreateDocument returns a valid document, I have tested it by loading it to radRichtextbox without printing.

Hopefully you can see directly what is wrong in my code... if you can provide sample project, that would also help.

 I'm using WPF version of Telerik controls (ver. 2011.2.712.40)

Auvo
