Dialog Parameters do not exist error on Custom Dialog example

[Fred]

I'm trying to use the example for the Rad Custom Dialog, and I'm getting this error
when I click on my custom tool button.



Sys.ArgumentNullException: Dialog Parameters for the <xxx> dialog do not exist
Parameter name: dialogName

Any thoughts?

I'm using the example but I was trying to call my own user control.
I changed the "'s in the String.format to single 's because they were giving me syntax issues. I tried it both ways.

<script type="text/javascript">
Telerik.Web.UI.Editor.CommandList["InsertHyperText"] = function(commandName, editor, args)
{
var myCallbackFunction = function(sender, args){
editor.pasteHtml(String.format("<a href={0}>{1}</a> originalAttribute='href' originalPath='{0}>{1}</a>' originalAttribute='href' originalPath='{0}>{1}</a>' ", args.href, args.text))
}
editor.showDialog("InsertHyperText", {}, myCallbackFunction);
};

</script>

Hi Fred,

Please, see the following help article on the subject: Adding Custom Dialogs.

If you want to avoid the usage of dialog definitions for the custom dialogs you should use the showExternalDialog  method to open the custom dialogs.

Why are the parameters for an RadEditor.showExternalDialog() callbackfunction different from a RadWindow onclientclose function?
Am I missing something?
Thanks

Darryl


e.g.
// RadWindow
function RadWindow_Close(returnvalue)
{
    var win = getRadWindow();
    win.argument = returnvalue;
    win.close();
}

function RadWindow_onclientclose(sender, args)
{
    // use sender.argument
}
// END RadWindow

// RadEditor showExternalDialog
function RadEditor_showExternalDialog_Close(returnvalue)
{
    getRadWindow().Close(returnvalue);
}

function RadEditor_showExternalDialog_callbackfunction(sender, args)
{
    // use args
}
// END RadEditor showExternalDialog

Hi Darryl,

Could you please, explain in more details your scenario and the problem that you experience? Are you trying to pass an argument from the Custom Dialog to the callback function of RadEditor?

Hey Rumen

My dialogs are working fine. The code I provided above is the way I had to go. I am just surprised that there is a difference in the usage of the callback function parameters.

cheers
