Tab navigation on gridview with custom column

Hi,

I have a gridview that consists of mix data bound columns and custom template column. The custom template column are basically a check box column and a calendar column. I used the techniques from this example to create those custom column (using the CreateCellElement)

http://www.telerik.com/community/forums/wpf/gridview/tab-navigation-in-a-grid-with-a-button-column.aspx

The check box column works fine with tabbing to/from the column. However the issue is with the Calendar column, as the tabbing doesn’t get the focus in the calendar control inside the column, and it doesn’t move away from it to move to the next column. Instead the focus moves to the next control beside the grid.

Any advice how to accomplish a smooth tab navigation between all column, and have the focus land in the inner controls when it is a custom column?

Regards

public override FrameworkElement CreateCellEditElement(GridViewCell cell, object dataItem)

{

cell.GotFocus += this.cell_GotFocus;

var picker = cell.Content as RmpDatePicker ?? new RmpDatePicker()

{

HorizontalAlignment = HorizontalAlignment.Stretch

};

this.BindingTarget = RmpDatePicker.SelectedDateProperty;

picker.SetBinding(this.BindingTarget, this.CreateValueBinding());

return picker;

}

private void cell_GotFocus(object sender, RoutedEventArgs e)

{

var picker = (sender as GridViewCell).ChildrenOfType<RmpDatePicker>().FirstOrDefault();

if (picker == null) return;

picker.Focus();

picker.HorizontalAlignment = HorizontalAlignment.Stretch;

}

private Binding CreateValueBinding()

{

var valueBinding = new Binding

{

Mode = BindingMode.TwoWay,

NotifyOnValidationError = true,

ValidatesOnExceptions = true,

UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged,

Path = new PropertyPath(this.DataMemberBinding.Path.Path)

};

return valueBinding;

}

[Solved] 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

[Solved] 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

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" />
