Is there a way to stop RadPanelBar from resetting when rebinding to datasource?

When the ItemsSource property is set by a background task (periodic timer), the RadPanelBar resets, i.e. the panels collapse and the selected item highlight disappears.

I have implemented a cache to save the state of the RadPanelBar and RadPanelBarItems so that it can be restored to its original state, after the ItemsSource property has been set. However this is causing a horrible flicker.

Is there a way to maintain the state of the RadPanelBar after the ItemsSource property has been set without having to do manually?

Would binding to an ObservableCollection instead make any difference?
(admittedly perhaps I should have done this in the first place, but didn't know about it until recently).

Thanks.

IsSelected Property

Hi Guys,

I was using the Telerik dll version 2009.2.701. something. At that time, if I switch the positions of two records, I would not lose the focus/selection on the original record. But after I upgraded to 2009.2.813. something, I am losing the focus after I switch the records. What I am trying to do now is to manually set the grid.Records[1].IsSelected = true. But it is not working. Any suggestions?

Thanks,

Untyped datasets and GridViewComboBoxColumn

Hi,

I am having a few issues with consuming datasets with the wpf grid. I have viewed the demos etc but cannot resolve this one.

The problem is the GridViewComboBoxColumn does not display the Display member on load, and when an item is selected in the employee column, and I navigate away, the value selected is not persisted in the grid row.

I have created a small example to show the problem. The codebehind is VB, as that is the language used for this cutover.

    
            <Window x:Class="Window1"

ObjectDataProvider to databind in RadCarousel ItemSource doesn't work

I am trying to databing a datatable result in XAML (declarative databinding). I tried it programmatically and it does work by setting the Itemsource of my radcarousel to the datatable in code. Can you please tell me where i am going wrong with my ObjectDataProvider.

XAML code:

    
            <Window x:Class="TelerikCarousel.Window1" 
        
                xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

                        {  
        
                            MessageBox.Show(ex.ToString());  
        
                        }  
        
                        return dt;  
        
                    }  
        
                }  
        
            }

I am just playing with a datable. My ultimate goal would be to be able to databind in XAML the carousel with a property of type ObservableCollection<>. Is that even possible? Thanks

IsResizable Property

HI Guys,

This really drives me nuts.

I have a radgridview control and I set the CanUserResizeColumns=True and for each column's setting I have set isResizable=True as well. However, I am still unable to resize the columns by dragging the mouse. Did I miss anything? When I place the mouse in between two columns' headers, I don't even see that 'line seperator'.

Thanks,

GridView

A Few Newbie Questions on GridView

Hi Everyone,

First of all - I'm new to telerik's controls, and I like what I see so far... great job!

I've started using the RadGridView control for a project of mine and encountered the following questions. I would greatly appreciate your help here:

1. How do I remove the left-most column (not a data column, whenever a row is selected it has a little right arrow in it)?

2. I've added a Combo column which works great, except for one little thing --- it is impossible to know that the column's cell is a combo box until the user actually double clicks on it. Is there a way to make it appear and respond as a combo box straight off?

3. Whenever a row is selected, I would like to display a set of content below it (description on the item, a list of other relevant items, etc.). How do I do this?

4. I've used a GroupDescription which works well, however, the value by which the rows are grouped does not appear in the group's title. What am I doing wrong?

Thank you for your help!

Beta Issue: 2009 Q3

We just got the latest beta release 2009.3.1023.35 and we are getting a NullReferenceException exception while the grid attempts to apply a header template.

System.NullReferenceException was unhandled

Not able to invoke RowEditEnded or CellEditEnded eventhandler from celltemplate type column of radgridview

I have used radgridview with celltemplate for column. I am not able to call  RowEditEnded or  CellEditEnded eventhandler on click of cell to edit the cell value. If I removed celltemplate used for binding, then it is working fine and corresponding celledittemplate is displaying and RowEditEnded or  CellEditEnded event handler is also invoking.But, if I am putting both inside GridViewDataColumn tag, it is not working. I am putting my code below for reference.

<telerik:GridViewDataColumn DataMemberBinding="{Binding Path=FirstName}">
                 <telerik:GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBox BorderThickness="0" Text= "{Binding FirstName}" Foreground="#0066cc"   Width="100" TextAlignment="Center" />
                        </DataTemplate>
                    </telerik:GridViewColumn.CellTemplate>
                    <telerik:GridViewColumn.CellEditTemplate>
                        <DataTemplate>
                            <TextBox BorderThickness="0" Text= "{Binding FirstName,Mode=TwoWay}" Foreground="#0066cc"   Width="100" TextAlignment="Center" />
                        </DataTemplate>
                    </telerik:GridViewColumn.CellEditTemplate>
                </telerik:GridViewDataColumn>

Please help me in that. I just want to call RowEditEnded or  CellEditEnded method on click of cell for editing purpose. But that cell using celltemplate. It is very very urgent.
