Hi,

 

I'm currently stuck a little bit.

My current grid has a column which has to be readonly (not changeable), so I define it as readonly.

But, when the user click on the insertionrow a cell editor should appear to provide a selection of values.

But being readonly the column cannot display a cell editor.

 

I've tried to overcome this by overwriting BeginEdit and cancel it if the user selects the "readonly" column,

but by clicking on another column the full row is in edition mode and the user can change the value of

the "readonly" column too.

 

What's the simplest way to supply a cell editor of a readonly column only in the insertionrow?

 

Thanks,

Michael

Set the InsertonRow's ReadOnly property to false.

Hi Jenny,

 

thanks for your answer, but that does not do the trick.

If the column has ReadOnly=true, setting InsertionRow.ReadOnly=false will have no effect.

Here's the code I use:

 

private void InitializeGrid()

{

jwpGridTZBJeEART.Columns.Create("SubEnergyKind", Core.Resources.Energy.SubEnergyKind(), "E_ART1", new JWPGrid.Editors.JWPDataGridControlComboBoxCellEditor(_subEnergyKindDataSource)).ReadOnly = true;

 

// Create the insertion row.

DataTemplate NewDataTemplate = new DataTemplate();

FrameworkElementFactory NewInsertionRow = new FrameworkElementFactory(typeof(JWPDataGrid.InsertionRow));

NewInsertionRow.SetValue(JWPDataGrid.InsertionRow.ReadOnlyProperty, false);

NewDataTemplate.VisualTree = NewInsertionRow;

jwpGridTZBJeEART.View.FixedHeaders.Add(NewDataTemplate);

 

_dataGridCollectionView = jwpGridTZBJeEART.CreateDataGridCollectionView(_facade.saldo_tzbDataTable.DefaultView, typeof(DataRowView));

_dataGridCollectionView.ItemProperties.Add(new JWPDataGrid.DataGridItemProperty("SubEnergyKind", "E_ART1", typeof(string), true));

 

jwpGridTZBJeEART.InitializingInsertionRow += new EventHandler<Xceed.Wpf.DataGrid.InitializingInsertionRowEventArgs>(jwpGridTZBJeEART_InitializingInsertionRow);

}

 

void jwpGridTZBJeEART_InitializingInsertionRow(object sender, Xceed.Wpf.DataGrid.InitializingInsertionRowEventArgs e)

{

e.InsertionRow.Cells["SubEnergyKind"].CellValidationRules.Add(new SubEnergyKindValidationRule(jwpGridTZBJeEART));

e.InsertionRow.ReadOnly = false;

}

"Columns.Create" is a little method I wrote to simplify column creation.

The InitializingInsertionRow-Event will only fire if the insertion row switches to edition mode.

The ComboBox-CellEditor shall only be active in the insertion row.

 

Any other options I can try?

 

Thanks,

Michael
