How To

Use Telerik RadEditor for ASP.NET AJAX in a Windows application

Solution

Although RadEditor is an ASP.NET control, you can use it in your Windows application. The steps below show how to cope with this task.

You can find how to use *RadEditor for ASP.NET AJAX *in your Windows application using the steps below. We will get the HTML content from the editor in the following live example Default Settings in order to show it in a message box. 1. Create a Windows Application project.

2. Add a reference to the Microsoft HTML Object Library assembly (Microsoft.mshtml.dll). You can find it in your Global Assembly Cache.

3. From the toolbox drag a *WebBrowser *control to your Windows Form.

4. In the Form_Load *event handler set the following URL for the WebBrowser control. This URL leads to a page which contains *RadEditor:

this.webBrowser1.Url = new Uri( "http://www.telerik.com/DEMOS/ASPNET/Prometheus/Editor/Examples/Default/DefaultCS.aspx" ); 

5. Then create a button and in the its *Button_Click *event handler, perform the procedures below.

6. Make sure that the *RadEditor *has loaded successfully before getting its HTML:

if (this.webBrowser1.ReadyState == WebBrowserReadyState.Loading ||          
    this.webBrowser1.ReadyState == WebBrowserReadyState.Uninitialized)  
{          
     MessageBox.Show(  "Please wait for RadEditor to load first."  );          
     return  ;          
}  

7. Register a script function to extract the HTML produced by RadEditor:


string jsFunction =           
            @"function GetEditorHtml()      
            {      
                return $find('RadEditor1').get_html(true);      
            }";             

IHTMLDocument doc1 = (IHTMLDocument)this.webBrowser1.Document.DomDocument;             
HTMLWindow2 iHtmlWindow2 = (HTMLWindow2)doc1.Script;            


8. Register the script on the form:

iHtmlWindow2.execScript(jsFunction,  "javascript" ); 

9. Finally, call the function to get the editor's text and to show it in a message box:

try      
{      
     object res =  this .webBrowser1.Document.InvokeScript( "GetEditorHtml" );      
     MessageBox.Show(res ==  null  ?  "null"  : res.ToString(),  this.Text);      
}      
catch (Exception ex)      
{      
     MessageBox.Show(ex.ToString(),  "RadEditor's text: "  +  this.Text);      
}
