Clicked item at times returns null eventhough the item is clicked in Rad Grid View

Hello,
I have a grid view where i have displayed my results. I have a double click event by which i try to find the clicked item. But the clickedItem returns null at times. The same code gives porper clicked items most of the times, but once in a while it returns null for the clicked item. Many of my colleauges are facing similar difficulty with Grid View.

private

void RadGridViewMouseDoubleClick(object sender, MouseButtonEventArgs e)

{

if (radGridView.CurrentItem == null) return;
//
// some code
//

}

here the ( radGridView.CurrentItem ) returns null at times, even though the current item details could be seen while debugging.

Populating a DataGrid with Dynamic Columns

In this blog post the author describes populating a datagrid in a SilverLight application dynamically at runtime. I'm wondering how the same might be accomplished in a WPF application using RadGridView. Porting her solution shouldn't be too difficult I'm just not sure as to the XAML, in particular the item templates. Can some one offer some insight? Thanks.

File Thumbnail

I would love to have an easy way to display the thumbnail preview of a file. The Windows Shell does it, but the pInvoke code required to make this work is excessive.

Something like this:
http://stackoverflow.com/questions/1439719/c-sharp-get-thumbnail-from-file-via-windows-api

Perhaps a "RadFileThumbnail" control?

The Windows API Code Pack for Windows 7 has something like this, but you lock yourself into Windows 7 by using it.

[Solved] Q3 2011 Public Roadmap: Timeline Beta - What is it?

Hi,

I've been reading the Q3 2011 Public Roadmap (http://www.telerik.com/products/wpf/whats-new/roadmap.aspx) and it mentions a new control "Timeline Beta". I'm wondering if Telerik can provide more details about this control (maybe an idea of what it will look like and function?) and when this control might be able to be tested.

I'm working on a project that is looking to visualize a sequence of events over time graphically and it sounds like this may be the ideal control for this purpose, however I would like to check whether this control provides what I require and if it would work within our development timelime.

Kind regards,
Dave.

System.Web requirement

Hey,

The XAML format provider (Telerik.Windows.Documents.FormatProviders.Xaml) requires System.Web for HttpUtility.HtmlEncode. This basically means we cannot use it because our companies SOE only has the .net Client Profile installed. WPF apps really shouldn't need System.Web. Is there a technical reason that you cannot use an alternative such as SecurityElement.Escape?

Thanks,

Brock

[Solved] Drawing Component

Hello,
It is recommended that you include a Drawing control to your WPF control collection.
Drawing control to draw different shapes and diagrams like those on MS Visio.
It would be great that you have it.

Thanks.

RadWindow AutoResize

Hi,

I currently am using a RadWindow as a ModalDialog in a WPF application. The content in the window expands as the user clicks buttons and unlocks more menus. I need the window to adjust automatically to the expanding size of the content.
Here are my window settings from the xaml file:

MaxHeight="800" MaxWidth="730" SizeToContent="True" telerik:CanMove="True" telerik:ResizeMode="CanResizeWithGrip" ModalBackground="Transparent" CanClose="False"
Background="{x:Null}" Foreground="{x:Null}" WindowStartupLocation="Manual" Style="{DynamicResource LoginWindowStyle}" BorderBackground="{x:Null}" BorderBrush="{x:Null}" MouseLeftButtonDown="MoveLoginBox" HeaderTemplate="{DynamicResource HeaderTemplate}">

Is there something I am doing wrong or is there a bug somewhere?
Also, I'm not sure if this is related, I am not able to re-size the window at all.

Thanks
Don

Caliburn Micro, RadGridView and Button in a template

Hello,

I've developed a RadGridView as follow :

 <telerik:RadGridView Grid.Row="1" ItemsSource="{Binding SecuritiesNoteResult}" AutoGenerateColumns="False">
            <telerik:RadGridView.Columns>
             <!-- some other grid-->
                <telerik:GridViewDataColumn UniqueName="FileOpen" Header="Visualizza" x:name="test">
                    <telerik:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <Button HorizontalContentAlignment="Center" Click="Button_Click" >
                                <Button.Content>
                                    <StackPanel Orientation="Horizontal">
                                        <Image Source="/DOME;component/Media/pdfDocument.png" Height="20" Width="20" />

                                    </StackPanel>
                                </Button.Content>
                            </Button>
                        </DataTemplate>
                    </telerik:GridViewDataColumn.CellTemplate>
                </telerik:GridViewDataColumn>
            </telerik:RadGridView.Columns>       
        </telerik:RadGridView>

and in the viewmodel I've :

        public void test()
        {
            _windowManager.ShowWindow(new ReportViewModel(_repository));
        }

The event is not fired... I've tried both to put x:name on the Button and in the GridViewDataColumn...
What am I doing wrong?

Thanks

RowDetail record erased while sorting or filtering master grid.

Hi,
I have a gridview having a grid in its rowdetail, when row detail visibility changes i fetch data from database to load the row detail grid.
But the problem here is that when i sort or filter on the main grid, the data is removed from the already opened row detail grid.

Same thing happens when we have some controls in our rowdetails, and the values of expanded row details sets to blank when filtered or sorted.

Using "RowDetailsVisibilityChangedevent" to populate the rowdetails, due to some constraints not using "LoadingRowDetails".

Please let me know is there anything i can do so that those row detail grid data does not get removed when I do sorting or filtering on main grid.

Please reply its urgent.
Thanks
