Hello Rahul,

To prevent your button from posting the whole page back, you will need to add a return false;, e.g.

<input type="button" onclick="focusEditor();return false;">

One of the easiest ways to move the cursor to the end of the editor content is to select all content and then collapse the selection to the end, e.g.

function focusEditor()
{
var editor = $find("<%=RadEditor1.ClientID%>");
var doc = editor.get_document(); //or get_Document() in earlier versions such as Q1 2007
doc.execCommand("SelectAll", null, false);
//Collapse selection to the end
editor.getSelection().collapse();
}

Hello Rahul,

Here is an example that will set the cursor to the end of the text after a postback:

    
            <telerik:radeditor runat="server" OnClientLoad="OnClientLoad" ID="RadEditor1"> 
        
                <Content>sample content for test 123</Content> 
        
            </telerik:radeditor> 
        
            <asp:Button ID="Button1" runat="server" Text="Submit" /> 
        
            <script type="text/javascript"> 
        
            function OnClientLoad(editor, args) 
        
            { 
        
              setTimeout(function() 
        
              { 
        
                  editor.setFocus(); 
        
                  var doc = editor.get_document(); //or get_Document() in earlier versions such as Q1 2007 
        
                  doc.execCommand("SelectAll", null, false); 
        
                  //Collapse selection to the end 
        
                  editor.getSelection().collapse(); 
        
              }, 100); 
        
            } 
        
            </script>

All the best,

hi

I tried your code. but still i am getting an java script error.

"Object doesn't support this property or method". Following line has error:

var doc = editor.get_document();

I think he is not supporting these methods for rad Editor ( Q1 2007 version ). i have used both methods get_documents(); and
get_Documents();

Please give me the solution ASAP.

Regards

Hello Rahul,

No method (or variation thereof) called get_documents exists in RadEditor (nor has it ever existed).
If you are using an outdated version of the editor such as Q1 2007, then the method to call would be
get_Document, but not get_Documents.

Hi Rumen!

I am able to set focus to the editor content area and cursor in the end...

But when the content is too large , the cursor is still in the end but I am unable to scroll to the cursor ( i.e the end of the content )

Please help me in this..

Thanks..

Hi,

In such case you can fire the editor.get_contentAreaElement().scrollIntoView(); method.
