Problem in binding Combox as CellEditor / setting SelectedValueProperty through C# code

Supriya — Tue, 01 Dec 2009 15:41:28 GMT

Hi..I am using Xceed DataGrid For WPF 3.5 professional edition.

I am binding a combobox as cell editor through C# code and not throgh XAML. The selected value of the combobox is not retained in the cell after the edit. I want to set the SelectedValueProperty so that it will retain the selected value, but dont know what should i set it to?

System.Windows.FrameworkElementFactory comboBox = new System.Windows.FrameworkElementFactory(typeof(Xceed.Wpf.Controls.NavigableComboBox));

comboBox.SetValue(Xceed.Wpf.Controls.NavigableComboBox.ItemsSourceProperty, columnInfo.DomainValues.DefaultView);

comboBox.SetValue(Xceed.Wpf.Controls.NavigableComboBox.DisplayMemberPathProperty, "DomainValue");

comboBox.SetValue(Xceed.Wpf.Controls.NavigableComboBox.SelectedValuePathProperty, "DomainID");

//comboBox.SetValue(Xceed.Wpf.Controls.NavigableComboBox.SelectedValueProperty, "Xceed.Wpf.DataGrid.CellEditorBinding"); ???

dataGrid.Columns[columnInfo.Code].CellEditor = new CellEditor();

dataGrid.Columns[columnInfo.Code].CellEditor.EditTemplate = new System.Windows.DataTemplate();

dataGrid.Columns[columnInfo.Code].CellEditor.EditTemplate.VisualTree = comboBox;

I have gone throgh lot of documentation and posts, but did not find 'what to set' in SelectedValueProperty, through C#. Please help.

Autocomplete combobox

Tue, 17 Nov 2009 13:16:14 GMT

Hi!

I have a combobox in my datagrid, which I fill up with a list of names selected from database.

When I start typing, when the dropdown is open, I want the focus to shift to the name I'm typing.

so if there' s more than one name starting at the same letter, when I type letter two it shifts to the name consisting of both letters..

Is this possible?

ComboBox CellEditor for Datagrid within ElementHost on Winform - how?

Sandra — Thu, 14 May 2009 21:57:04 GMT

I am trying to display an Xceed WPF datagrid on a WinForm. I created a user control that is the datagrid, and then added the usercontrol to an ElementHost on the Winform.

That works, and I am able to display data. My problem is, I am trying to define one of the columns as a combobox editor. Where do I add the XAML code for defining this? I get errors when I add it to the custom control, something about the content is already defined.

I didn't see any samples that show a datagrid within an ElementHost on a Winform, that has a custom CellEditor defined. Can anyone help?

Capturing Click event of Button in a DataCell using MVVM

Shailesh — Mon, 23 Mar 2009 19:42:43 GMT

Hello,

I am using Model View ViewModel pattern. I have a button inside a DataCell of Xceed DataGrid. I want to use DelegateCommand to handle the click event of the button.

Also, I dont want to write anything for the same in my Code Behind. I want everything to reside in my ViewModel.

How can this be achieved. I thought of RoutedEvents / RoutedCommands but they need some entry in the Code Behind file.

This I want to eliminate.

Requesting you to please help on the same.

Thanks and Regards

SSA.

CellEditor loses focus immediately upon Edit

jim — Thu, 12 Mar 2009 21:00:54 GMT

What I really need is a really good walkthrough of how to use a celleditor in a DataGrid bound to a database...

But, at the moment, I have two immediate problems... Eternal gratefulness if anyone can help or point me in the right direction.

I have a DataGrid populated with "Modules." A "Module" can be assigned to a "Category" (but it is not required). The DataGrid displays the Category to which a Module is assigned. When I Edit the Module row, I want the user to be able to select from a combobox of Categories populated from a Database.

Currently, if a Module has no Category, I can click on the empty cell, which will display the correctly populated combobox. When I select a value fromt he ComboBox, the CB disappears (reverst to "View?") but there is no value present in the DataGrid row.

The second issue is that, when a Module already has an assigned Category, the Category shows properly in the DataGrid view, but if I click on the cell in an attempt to edit it (i.e. display the combobox), the 0-index row becomes selected and no combobox is ever displayed.

Any help at all... much much appreciated. Thank you!

CODE:

<Grid.Resources>

<xcdg:DataGridCollectionViewSource EditCommitted="dgcs_EditCommitted" x:Key="ID" Source="{Binding Source={x:Static Application.Current},Path=Modules}"/>

</Grid.Resources>

<xcdg:DataGridControl x:Name="CategoriesGrid" ItemsSource="{Binding Source={StaticResource ID}}">

<xcdg:DataGridControl.Columns>

<xcdg:Column FieldName="ID" Title="ID" ReadOnly="True" Visible="False" IsMainColumn="True"></xcdg:Column>

<xcdg:Column FieldName="CatName" Title="Category Name">

<xcdg:Column.CellEditor>

<xcdg:CellEditor>

<xcdg:CellEditor.EditTemplate>

<ComboBox.Resources>

</Style>

</ComboBox.Resources>

</ComboBox>

</DataTemplate>

</xcdg:CellEditor.EditTemplate>

</xcdg:CellEditor>

</xcdg:Column.CellEditor>

</xcdg:Column>

<xcdg:Column FieldName="DisplayName" Title="Module Name" />

<xcdg:Column FieldName="OrderVal" Title="Display Order" />

<xcdg:Column FieldName="CatOrder" Visible="False" />

<xcdg:Column FieldName="xtID" Title="Express Train ID" ReadOnly="True" />

</xcdg:DataGridControl.Columns>

How to bind Combo Box in DataGrid

Rahzam — Thu, 05 Mar 2009 16:28:34 GMT

Problems

1. I have data in DataTable. Need to bind with DataGrid. How can i do that?

2. I need to make one column as comboBox. In this combo box only two hard coded Values 'Dr' and 'Cr'. In DataTable I have 0 for Dr and 1 for Cr in column named 'dr_cr'. If DataTable cell contains 0 then Dr should be selected and if 1 then Cr should be selected. this cell is editable, mean i may be able to change Dr to Cr.

I will prefer to have XAML code for defining columns and grids and only assigning datasource to grid in C#. As we do in Desktop application. myGrid.DataSource = dtMyTable;

Please help me. I have spent two days only for this :(

Hi,

I am using a combobox in Cell edit template i am loading the combobox content when the edit is fired but after the ending edit i am getting the Member not the Value. My code is below:

XAML :

<xcdg:DataGridControl Grid.Row="2" HorizontalAlignment="Left" Name="NotesGrid" Width="800" Height="Auto" ItemContainerStyle="{StaticResource edite}" EditTriggers="SingleClick, CellIsCurrent, RowIsCurrent" CellEditorDisplayConditions="CellIsCurrent">

                                    <ComboBox SelectedValue="{xcdg:CellEditorBinding}" Loaded="ComboBox_Loaded" ></ComboBox>
                                </DataTemplate>
                            </xcdg:CellEditor.EditTemplate>
                        </xcdg:CellEditor>
                    </xcdg:Column.CellEditor>

                                <DataTemplate>
                                    <TextBox Text="{xcdg:CellEditorBinding}" TextWrapping="Wrap"/>
                                </DataTemplate>
                            </xcdg:CellEditor.EditTemplate>
                        </xcdg:CellEditor>
                    </xcdg:Column.CellEditor>
                </xcdg:Column>
                <xcdg:Column FieldName="CreatedBy" Title="Created By" ReadOnly="True" />

private void ComboBox_Loaded(object sender, RoutedEventArgs e)
        {
             note = new Note ();
             DataSet ds = new DataSet();
             ds = note.GetNoteType();
             ((System.Windows.Controls.ComboBox)(sender)).ItemsSource = ds.Tables[0].DefaultView;
             ((System.Windows.Controls.ComboBox)(sender)).DisplayMemberPath = ds.Tables[0].Columns["NoteType"].ToString();
             ((System.Windows.Controls.ComboBox)(sender)).SelectedValuePath = ds.Tables[0].Columns["NoteTypeID"].ToString();
