Printing Gridview contents

Hi All,

I am using Telerik WPF Radgridview 2010.2.924.35 version for Printing the contents of gridview. When i select Microsoft XPS Document, a xps file is created and it contains the proper data that is present in the gridview. When i print the contents after selecting the Printer, i am gettting the correct headers and number of rows and not the cell content. all rows have blank values. What is the problem? i followed the same steps followed in Printing demo in your samples. for the demo sample, i m getting all row values when a printer is selected.

But the only difference is in demo they have used gridviewdatacolumn to bind data. I used celltemplate and celledittemplate to bind row data. Why is the content missing. I also installed 2011 trial version and i ended up with the same issue. Any ideas or help is appreciated. Preferably code samples are welcome.

Thanks in advance,
Saranya.

AutoGeneratingColumn CellTemplateSelector

I am needing to apply celltemplateselectors at runtime to dynamic grid columns from observablecollection<T>.
Do you have any documentation or examples that show applying celltemplateselectors to grid columns in code behind purely?
I have DataTemplates in a Resource Dictionary and I would like to use the business object value in the cell to decide the datatemplate to select.

Example:

private void grid_AutoGeneratingColumn(object sender, GridViewAutoGeneratingColumnEventArgs e)

{

if (e.Column.UniqueName.Equals("SpecificColumn", StringComparison.CurrentCultureIgnoreCase))

{

e.Column.CellTemplateSelector =

// ... point to C# class that returns datatemplate from resource dictionary file

}

Animating elements in information layer

As a newbie to WPF I've been struggled with triggers and animations for a while.

This is my element in the information layer:

<telerik:InformationLayer.ItemTemplate>

<DataTemplate>

<Grid x:Name="TopLevelGrid" Width="Auto" Height="Auto"

telerik:MapLayer.Location="{Binding Location}" telerik:MapLayer.BaseZoomLevel="9">

<ToolTipService.ToolTip><ToolTip><ToolTip.Content>

...

</ToolTip.Content></ToolTip></ToolTipService.ToolTip>

<Ellipse Name="myEllipse" Width="20" Height="20"

Stroke="{Binding Stroke}" StrokeThickness="3"StrokeDashArray="2"

Fill="{Binding Fill}" Style="{StaticResource myStyle}" >

<telerik:MapLayer.HotSpot><telerik:HotSpot X="0.5" Y="0.5" /></telerik:MapLayer.HotSpot>

</Ellipse>

</Grid>

</DataTemplate>

</telerik:InformationLayer.ItemTemplate

The problem is that I want a property (or event) in my custom class for the element to trigger the animation. So far I've tried to do it both in XAML and in code without success.

I would be grateful if you could give me a hint or two of how to solve the issue.

Regards

Robert

AppointmentItem DataContext

Hey Telerik,

I'd like to have a reference to the resource column the AppointmentItem is shown in.
This is very useful to change the styling of the appointment based on the column it is shown in.
Since now there is only a reference to the Appointment ViewModel this is not possible.

In my current solution I add a "Resource" dependency property to the Appointment Data Context Proxy, and use reflection on the
groupheader's (GroupKey is the resource) AppointmentItems to set the extra property. However this is done in the a derivative class of the AppointmentsPanel and during it's arrangeoverride, needles to say it degrades performance.

Any suggestions?

Greetz,
Nico

Load image in cell when loading any database

Hi,

I have an app that loads any database and presents the data for the tables in a GridView. I do not define columns in the XAML since I load any database. I'd like to be able to determine when a column from the database contains images and display the images in the grid. Can you tell me how to do this? I see examples in the forms and KB but they all seem to create the columns in XAML since they know the database schema ahead of time.

Thanks,

Gord

Commit button binding

Hello! I'm working with the DataForm and I have what I would guess is a simple question. I'm using a DataForm to edit a single item and I'd like to bind the Commit button to an ICommand on my ViewModel. How do I go about doing that?
