I am using a RadPanelBar control, and when RadPanelBar expands and collapses, it run very fast. How to adjust the speed of RadPanelBar  expand and collapse?

I have a DataGrid that i have a TimePicker column in.  I manipulated the sample custom column to just include a TimePicker element.  It works fine except for when the element tries to validate the input selected.  I have bound it to a TimeSpan item, but it gives me the validation error "Object of System.DateTime cannot be converted to TimeSpan".  So im unsure where to bind the TimeSpan item to get the selected DateTime.TimeOfDay??

 

 

 

<telerik:RadGridView AutoGenerateColumns="False" NewRowStyle="{StaticResource NewRowStyle}" RowStyle="{StaticResource RowStyle}" Foreground="White" HorizontalGridLinesBrush="White" Margin="10,10,210,22" Name="groupGrid" SelectionMode="Single" SelectionUnit="FullRow" VerticalGridLinesBrush="White" SelectionChanged="groupGrid_SelectionChanged" CellEditEnded="groupGrid_CellEditEnding" RowIndicatorVisibility="Collapsed" ShowGroupPanel="False" ShowInsertRow="True" RowEditEnded="groupGrid_RowEditEnded">

 

 

 

 

<telerik:RadGridView.Columns>

 

 

 

 

<telerik:GridViewDataColumn Header="Task Name: " DataMemberBinding="{Binding Name}" />

 

 

 

 

<telerik:GridViewDataColumn Header="Description: " DataMemberBinding="{Binding Description}" />

 

 

 

 

<telerik:GridViewDataColumn Header="Solution: " DataMemberBinding="{Binding Solution}" />

 

 

 

 

<my:TimePickerColumn DataMemberBinding="{Binding StartTime}" Header="Start Time" TimeInterval="0:30:0"/>

 

 

 

 

 

<telerik:GridViewDataColumn Header="End Time: " DataMemberBinding="{Binding EndTime}" />

 

 

 

 

<telerik:GridViewDataColumn Header="Elapsed:" UniqueName="Elapsed" DataMemberBinding="{Binding ElapsedTime}" />

 

 

 

 

 

</telerik:RadGridView.Columns>

 

 

 

 

</telerik:RadGridView>

 

Good day,

I am using RadGridView control using 2009 Q2 version of Telerik. And i have the following problem.

I am using bindings for having some control on some behavior into the Grid. My idea is, binding the column to a property, set unable and disable the checkbox we have in the column. For that i use RelativeSource FindAncestor


As you can see in the code, I have binding on "IsEnabled" property for allowing or not to check on the checkboxes which was edited or not.
The binding works great in the header but, it ignores in the cell!

Any ideas? Why is that happening? Any solution for making the cells work in the same way as the header?

Thanks in advance.

Regards,
Alvaro

Hello!

I can't find any obvious documentation about my specific use case, so please help me along here:

I have a class such as this:

    public class ProductPrognosis
    {
        public string PartNumber { get; set; }
        public Dictionary<DateTime, int> Prognosis { get; set; }
    }

This class gets filled with data extracted from an Excel document.
I then have a list of these objects that I use as my ItemsSource on a chart control:

<telerik:RadChart  ItemsSource="{Binding Prognoses}" Grid.Row="1" Margin="4,0" Background="#66ffffff" />

My problem is, I cannot find a way to tell RadChart how to get at the series in the collection..
I would have expected some properties, such as SeriesNameProperty and SeriesDataProperty that when defined made RadChart auto-create series based on the set of data presented..

Looking at the samples you have published, I only see manual definition of series using quite verbose XML. And I fear that is not an acceptable solution. WPF UIs are meant to be data driven, not tersely defined in XAML.

I hope someone can solve this with a simple solution, I would hate to have to create a whole suite of magical tools that generate irrelevant objects (to me) on the fly..

hey guys,

I'm experiencing a problem with Drag And Drop within my RadTreeView...  This worked fine under 2010 Q3, just since installing the SP1 I am getting this bug.. the code from the RadTreeView is below.... 

the error i'm receving is..

"An exception of type 'System.InvalidOperationException' occurred in Telerik.Windows.Controls.dll but was not handled in user code

Additional information: Root AdornerLayer Not Found. Please make sure that your root visual is Window or other element that has an adorner layer. Alternatively, wrap your root panel in an <AdornerDecorator> element."

further info...

"Error. Root AdornerLayer Not Found. Please make sure that your root visual element is window or other element that has an adorner layer alternatively wrap your root panel in an <AdornerDecorator> element.

When attempting to drag an element..



I'm unsure if this is a bug or if i just need to wrap my user control in an AdornerDecorator, but some further information would be great.

Hi,
     I am using MVVM pattern. I have a telrik gridview and i want to capture its CellLostFocus event,for that i am using CellEditEnded event. But problem is that this event is firing when i am tabbing out of the cell,not on lost focus of the cell. Is there any way to capture CellLostFocus event of gridview. Since I am using MVVM pattern so I also dont want to write any code in code behind.

Thanks

Hi,
Is it possible to remove a RadPane from a RadDocking, instead of hiding it?
Ideally, I'd like to wire up the Close so that it removes the "closed" pane from the control.  Is this possible?

Thanks.

Hi,
just recently started evaluating your products. The demo page is excellent, but i ran into an error of some sort.
On the wpf demos i was trying out the GridView -> Performance -> Client binding to 1 mil. records, i get an error when i start scrolling the data by using the scrollbar slider. It doesn't go to an error if i use either the page down area or the arrows.

I'm using IE 8

Hi,

Is is possible to used a custom sort order to perform a column sort in a GridView column?

For example,  I want to use a custom sort to sort text column row values 1,2,10,3 to have a sort order of 1,2,3,10 rather then 1,10,2,3

Thanks
Daniel
