Hi!

Currently, it's impossible to create a custom dialog. If this feature is very important for you, please add a new suggestion in our Support Center.

Thanks for your kind help.

I want another help.I add a customtoolbar and want to display an image in the editor using javascript;I put the source for the image in an hiddenfield.i attach the code below.

function PasteEmailTemplate(commandName)
     {
     var imgSource=document.getElementById("ctl00_ContentPlaceHolder1_hidImgSource");
     //window.location="Mail.aspx?img="+imgSource;
    switch(commandName)
     {
        case('pastetemplate'):
            var htmlName=document.getElementById('ctl00_ContentPlaceHolder1_ASPxHtmlEditor1');
       
            HtmlEditor.ExecuteCommand(ASPxClientCommandConsts.SELECT_ALL, null);
            HtmlEditor.ExecuteCommand(ASPxClientCommandConsts.PASTEHTML_COMMAND, imgSource.value);
            break;
    }
    }

hidImgSource.Value = "<img src='C:/Documents and Settings/All Users/Documents/My Pictures/Sample Pictures/Water lilies.JPEG' width='200' height='100'>";

But the image is not displayed in the editor .what is the problem.

The problem is that you incorrectly define the image URL.
How to define the image URL, see the following online resource:
http://www.w3schools.com/tags/att_img_src.asp

var imgSource=document.getElementById("ctl00_ContentPlaceHolder1_hidImgSource");    
     var a='<img src='+imgSource.value+'></img>';

switch(commandName)
     {
        case('pastetemplate'):
            var htmlName=document.getElementById('ctl00_ContentPlaceHolder1_ASPxHtmlEditor1');
       
            HtmlEditor.ExecuteCommand(ASPxClientCommandConsts.SELECT_ALL, null);
            HtmlEditor.ExecuteCommand(ASPxClientCommandConsts.PASTEHTML_COMMAND, a);
            break;
    }

I add one image like the code given above.How i add more images on customtoolbarclick.
