I know that I must use an ElementHost to display a WPF control in a WinForm, but as the WPF control is third party software and it only comes with an XML file and a DLL file.
The control is AvalonEdit, I added both the ICSharpCode.AvalonEdit.xml and ICSharpCode.AvalonEdit.dll files to my project, and I went to Project -> Add Reference and added the DLL as a reference. Now I can access the ICSharpCode namespace in my code, all of the classes and methods are exposed, but from this point I am unsure how to actually use the control in my WinForm.
I was expecting a WPF control to appear in the Solution Explorer, but it does not. I tried adding an ElementHost control to my WinForm anyways, but when I try to Select the Hosted Content, no controls appear, so it doesn't know about my WPF control. How can I use the AvalonEdit WPF control in my WinForm?
If you want to be able to set the hosted content at design time the control needs to be part of your solution. One way to achieve that is to create a custom WPF user control which contains the AvalonEdit component you want to use. I.e
Create a WPF User Control library project and create a user control
containing the AvalonEdit component.
Add the User control project to your Winforms solution.
Now you should be able to select your new user control as the hosted content.
Or you could add the AvalonEdit control directly in code like this:
public Form1()
{
InitializeComponent();
ElementHost host= new ElementHost();
host.Size = new Size(200, 100);
host.Location = new Point(100,100);
AvalonEditControl edit = new AvalonEditControl();
host.Child = edit;
this.Controls.Add(host);
}
Not sure what the control is called so replace the AvalonEditControl as appropriate.
You'll want an example on how to do Code Colouring/Syntax Highlighting as well:
public Form1()
{
InitializeComponent();
ICSharpCode.AvalonEdit.TextEditor textEditor = new ICSharpCode.AvalonEdit.TextEditor();
textEditor.ShowLineNumbers = true;
textEditor.FontFamily = new System.Windows.Media.FontFamily("Consolas");
textEditor.FontSize = 12.75f;
string dir = #"C:\Temp\";
#if DEBUG
dir = #"C:\Dev\Sandbox\SharpDevelop-master\src\Libraries\AvalonEdit\ICSharpCode.AvalonEdit\Highlighting\Resources\";
#endif
if (File.Exists(dir + "CSharp-Mode.xshd"))
{
Stream xshd_stream = File.OpenRead(dir + "CSharp-Mode.xshd");
XmlTextReader xshd_reader = new XmlTextReader(xshd_stream);
// Apply the new syntax highlighting definition.
textEditor.SyntaxHighlighting = ICSharpCode.AvalonEdit.Highlighting.Xshd.HighlightingLoader.Load(xshd_reader, ICSharpCode.AvalonEdit.Highlighting.HighlightingManager.Instance);
xshd_reader.Close();
xshd_stream.Close();
}
//Host the WPF AvalonEdiot control in a Winform ElementHost control
ElementHost host = new ElementHost();
host.Dock = DockStyle.Fill;
host.Child = textEditor;
this.Controls.Add(host);
}
ElementHost host = new ElementHost();
host.Size = new Size(200, 100);
host.Location = new Point(100, 100);
ICSharpCode.AvalonEdit.TextEditor edit = new
ICSharpCode.AvalonEdit.TextEditor();
host.Child = edit;
this.Controls.Add(host);

Hello (and sorry for my English), I have a problem with Printing RTF using RichTextBoxPrintCtrl and TabControl.
1) The tabcontrol got no tabs on Design, when the Form Load, it will get a tab with the method AddTab(Title). (Don't mind about other variables).
private void AddTab(string Name = "Nuova Nota*")
{
RichTextBox Body = new RichTextBox();
Body.Name = "Body";
Body.Dock = DockStyle.Fill;
Body.ContextMenuStrip = contextMenuStrip1;
TabPage NewPage = new TabPage();
string DocumentText = Nome;
if (Nome == "Nuova Nota*")
{
TabCount += 1;
DocumentText = Nome + TabCount;
}
NewPage.Name = DocumentText;
NewPage.Text = DocumentText;
tabControl1.Visible = true;
NewPage.Controls.Add(Body);
tabControl1.TabPages.Add(NewPage);
tabControl1.SelectedTab = NewPage;
Nomi_Files.Add(NewPage.Text);
Path_Files.Add("");
}
2) Once the tab is created, you can start to write, change colors, fonts, etc...
To get access on the document that you are making, i use a GetCurrentDocument that return the "Body" of the selected tab:
private RichTextBox GetCurrentDocument
{
get { return (RichTextBox)tabControl1.SelectedTab.Controls["Body"];}
}
Now, all the functions (save, open, fonts, colors...) Works Fine, i wanted to print my document and keep the style, so i Googled and i found this: How to print the content of a RichTextBox control by using Visual C#
I made the RichTextBoxPrintCtrl.dll, added the resource on my project, added the item inside the toolbox, but i can't change the RichTextBox that i create from Code, with RichTextBoxPrintCtrl.
The error that i get is:
Error 1 'RichTextBoxPrintCtrl' is a 'namespace' but is used like a
'type'
How i can use that RichTextBoxPrintCtrl without drag and drop it inside the design form?
Ok, i figured out how to solve it:
instead of declaring like:
RichTextBoxPrintCtrl NameControl = new RichTextBoxPrintCtrl();
we need to declare the namespace so:
RichTextBoxPrintCtrl.RichTextBoxPrintCtrl NameControl = new RichTextBoxPrintCtrl.RichTextBoxPrintCtrl();
Everything works fine :) thanks;
I'm creating simple browser just navigate the "google".
How can I do it in my point?
Viewer = new System.Windows.Forms.Panel();
private void Browser_Click(object sender, EventArgs e)
{
WebBrowser web1 = new WebBrowser();
web1.Navigate("http://www.google.com/");
Viewer = web1 // It gets error
}
Just drag out the WebBrowser control like you would with any other control..
Then access it by its name (default would be WebBrowser1 i think so modify your code to be WebBrowser1.Navigate("http://www.google.com/");.)
Reason for error is you are trying convert "Web Browser" control to "Panel" control type.
Change :
Viewer = web1;
To:
Viewer.Controls.Add(web1); // add as child control
web1.Dock = DockStyle.Fill; // fill style in viewer
Make sure your viewer is docked in Parent control as needed.
Hope it helps..!!
try
web1.Url = new Uri("http://www.google.com");
Is there a way to add a control like in Win Forms C# Button b = new Button(); and then add it just like Form1.Controls.Add(b);
I can't do this in WPF because I don't have a Controls attribute in the Window class. How can I do this. I read this of just putting a Panel, dock it to fill and then there I use this:
myPanel.Children.Add(b);
But then it comes to me again. How do I create and add a Panel and dock it to fill?
If I use Panel p = new Panel(); it marks error. And how do I add the panel to my MainWindow?
You can add a stackpanel to window like below.
StackPanel myPanel = new StackPanel();
myWindow.Content = myPanel;
Like #HighCore said below, it is not cleaner to add controls in codebehind. Use XAML wherever it is possible and avoid adding controls in code behind
You can create any structure in C# as you can in XAML.
var p = new Panel();
Above doesn't work because Panel is an abstract class. You can, however do:
var p = new StackPanel();
var g = new Grid();
var wp = new WrapPanel();
var dp = new DockPanel();
//Etc.
See all panels here: http://msdn.microsoft.com/en-us/library/system.windows.controls.panel(v=vs.110).aspx
<Window ...>
<StackPanel>
<TextBox/>
</StackPanel/>
</Window>
is equivalent with (from your MainWindow.xaml.cs):
var sp = new StackPanel();
sp.Children.Add(new TextBox);
Content = sp;
EDIT: Just to be clear, you ONLY want to create your UI in C# if it is dynamic in nature. If you know which fields will be there, always, use XAML. It is the HTML of WPF. Coding everything in the code-behind is the web-design equivalent of sending a blank HTML file and creating everything in JavaScript.
I've a tabcontrol on my page with 2 tabs. Now I want to create another tabcontrol dynamically and want to add the existing tab control to dynamically created tab control tabs.
Is is possible? I'm not able to add this.
Here is my code:
TabControl tbdynamic = new TabControl();
TabPage tbpaagedynamic = new TabPage();
tbpaagedynamic.Controls.Add(statictabcontrol);
tbdynamic.TabPages.Add(tbpaagedynamic);
Any idea?
Yes, it is posiible.
Add dynamic tab to Form :
this.Controls.Add(tbdynamic);
example
TabControl tbdynamic = new TabControl();
tbdynamic.Height = 200;
tbdynamic.Width = 200;
TabPage mPage = new TabPage();
mPage.Text = "Test Page";
tbdynamic.TabPages.Add(mPage);
mPage.Controls.Add(statictabcontrol);
statictabcontrol.Top = 0;
statictabcontrol.Left = 0;
this.Controls.Add(tbdynamic);
Just add the bringToFrontMethod() at the end of adding it to your Window.
tbdynamic.BringToFRont();
I am working on an ERP project. it is a button on treeView box and when it is clicking on a button in treeView it must create a Tab with its content (content which is defined-designed before).
I can add a tab programically but how can I design its content?
Adding this to your click event of your treeview should do what you are after:
var contentControl = new ContentControl (); //This is what we will put all your content in
contentControl.Dock = DockStyle.Fill;
var page = new TabPage("Tab Text"); //the title of your new tab
page.Controls.Add(contentControl); //add the content to the tab
TabControl1.TabPages.Add(page); //add the tab to the tabControl
To your project, add a new UserControl called ContentControl (or whatever you need, just using this in my example), and fill it with all the contents you want to appear in your tab.
You have few solutions, the simplest one is to create TabPage, create desired Controls, set up their properties (i.e. Size, Location, Text etc.), add them to the TabPage and then add TabPage to the TabControl.
TabPage tp = new TabPage();
//create controls and set their properties
Button btn1 = new Button();
btn1.Location = new Point(10,10);
btn1.Size = new System.Drawing.Size(30,15);
//add control to the TabPage
tp.Controls.Add(btn1);
//add TabPage to the TabControl
tabControl1.TabPages.Add(tp);
the second solution is to override TabPage in your class, for instance CustomTabPage where you will set up controls in the constructor of the class. Then, when you want to add new TabPage, create your CustomTabPage instance and add it to the TabControl.
public class CustomTabPage : TabPage
{
public CustomTabPage()
{
//create your Controls and setup their properties
Button btn1 = new Button();
btn1.Location = new Point(20, 20);
btn1.Size = new System.Drawing.Size(40, 20);
//add controls to the CustomTabPage
this.Controls.Add(btn1);
}
}
//Create CustomTabPage
CustomTabPage ctp = new CustomTabPage();
tabControl1.TabPages.Add(ctp);
the third solution (the best but the most complicated) is to create your desired UserControl with everything you want on it (you can use Designer help), then create an instance of your UserControl, Create a TabPage and add UserControl on the TabPage. Then add TabPage to the TabControl.
public partial class CustomControlForTabPage : UserControl
{
public CustomControlForTabPage()
{
InitializeComponent();
}
}
//Create CustomControl
TabPage tp = new TabPage();
CustomControlForTabPage ccftp = new CustomControlForTabPage();
//set properties you like for your custom control
tp.Controls.Add(ccftp);
tabControl1.TabPages.Add(ctp);
Add a new user control to the project then use the designer to do controls/layout, then when you click all you do is add a new instance of the user control to the tab - probably docked to fill the tab unless your form's size is fixed.
