Re: ComboBox CellEditor for Datagrid within ElementHost on Winform - how?

Mohamed [Xceed] — Fri, 15 May 2009 20:56:54 GMT

Hi Sandra,

the use of a CellEditor in a DataGridcontrol is the same regardless of whether it is used directly in a Wpf application or as a WPF usercontrol within an ElementHost of a Winform application.

Find Below an example that demonstrates the use of the datagrid within an ElementHost on a Winform.

Winform Form1.cs file:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using System.Windows.Forms.Integration;

namespace _20967

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

ElementHost host = new ElementHost();

host.Dock = DockStyle.Fill;

UserControl1 uc = new UserControl1();

host.Child = uc;

this.Controls.Add(host);

}

UserControl1 Xaml file:

<UserControl x:Class="_20967.UserControl1"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

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?
