How to bind different sources to combos in grids

I have a grid in which comboboxes are shown in each row to allow for selection of color for the item in that row.

Now we wish to have different lists of colors depending on the row; i.e. the itemssource for the comboboxes are no longer the same.

Before I had a single color-list on the viewmodel for the grid and xaml-databound-bound the comboboxes to that.

How do I get different itemssources for the comboboxes?

Thanks for any input,

Anders, Denmark

XamlSerializable cant serialize my collection

Hi
In order to add some hidden "meta data" to our RadDocuments
we decided to derive the Section class and add

public class EditorSection : Section

{

private ObservableCollection<Metadata> _metadata = new ObservableCollection<Metadata>();

//[XamlSerializable]

public ObservableCollection<Metadata> Metadata

{

get { return _metadata; }

set { _metadata = value; }

}

Now we can create documents in XAML such as:

<c:EditorSection>

<c:EditorSection.Metadata>

<c:Metadata Name="DocumentId" Value="{00000-..-..-..}" />

<c:Metadata Name="Owner" Value="JohnWSmith" />

</c:EditorSection.Metadata>

<t:Paragraph>

<t:Span Text="Hi">

</t:Span>

</t:Paragraph>

</c:EditorSection>

However when saving the Document with XamlFormatProvider
the Metadata stuff is removed.

When Debugging my metadata class I can see a two instances
are created and the two props are assigned on load.

When I try an add the [XamlSerializable] attribute to my property
and also to the properties of the MetaData class
I get an runtime XamlParseException on loading the document:
Can't convert object of type "System.String" to "ObservableCollection<MyNameSapce.MetaData>"
The line in question is:

Telerik.Windows.Documents.FormatProviders.Xaml.XamlFormatProvider.Import(String input) in c:\TB\102\WPF_Scrum\Release_WPF\Sources\Development\Documents\FormatProviders\Xaml\XamlFormatProvider.cs:Line 126.

So it seems the XamlFormatProvider can't deal with the markup properly.
Is there a way to "tell" the XamlFormatprovider how (de)serialize my meta data collection
Do I need to specify a typeconverter or value converter also?

Thanks

RadGridview Print Format problem

Hi,
In my application, i am trying to view the contents in the gridview in the form of print preview dialog.
I downloaded code from http://www.telerik.com/community/code-library/wpf/gridview/radgridview-print-and-print-preview.aspx
The print preview window showing the grid values. But at the end of each page, bottom of the line, the last row data was partially cut in one page and remaining in next page. Please find the attached image.

Am i missing any settings?

GridViewComboBoxColumn not showing info in the grid

Hi all,

The comboboxcolumn is not showing the info from the linked table:
this is the code snippet I'm using to define the column

column = GridViewComboBoxColumn.new()

column.DataMemberBinding = bind

column.UniqueName = colname

column.IsComboBoxEditable = true

column.ItemsSource = data_table_source.DefaultView

column.DisplayMemberPath = "name"

column.SelectedValueMemberPath =

"id"

# add the column to the datagrid

raddatagrid.Columns.Add(column)

I can edit the column and the combobox appears populated in full, but as soon as I select an item the view doesn't show the result.

Any suggestions?

I'm using IronRuby, I can make it work as expected with the WPF .net 4.0 DataGrid without any problem.

Regards

Eduardo

Bindning to another element property from AlternateRowStyle

Hello.

I have a RadGridView. And a fake element below. I want to bind AlternativeRowBackground to fake element Background property. And I want to do so in AlternativeRowStyle (because in code-behind this style is upgraded with other triggers, that change Background property due to some logic) and not in AlternativeRowBackground property.

Is it possible to do so somehow?

<telerik:RadGridView ItemsSource="{Binding Data}" AlternationCount="2">

<telerik:RadGridView.AlternateRowStyle>

<Style TargetType="telerik:GridViewRow">

<Setter Property="Background" Value="{Binding ElementName=FakeButton, Path=Background}"/>

</Style>

</telerik:RadGridView.AlternateRowStyle>

</telerik:RadGridView>

<Button x:Name="FakeButton" Background="Blue" Content="Button" />

ScrollIntoView for collapsed items

I am using a TreeListView and want to scroll to a particular data item. This works fine if I have expanded the entire tree (hence I assume actually generating rows for all the data items). But if the tree is collapsed ScrollIntoView does not work. What is the recommended method to programatically display a particular data item in a TreeListView even if that data item has not been visible previously.

My datasets only contain approx 1000 items or so. Can I disable dynamic loading? I've had lots of problems trying to work with rows that apparently have not actually been created yet.

Thanks
