Custom Image Manager Dialog Broken

[Chris Queen]

We were using this code to set a value in the editor from a custom dialog:

Telerik.Web.UI.Editor.CommandList["BackgroundImage"] = function (commandName, editor, commandArgs) {
        var argument = Telerik.Web.UI.Editor.CommandList._getLinkArgument(editor);
        Telerik.Web.UI.Editor.CommandList._getDialogArguments(argument, "A", editor, commandName);
        var callbackFunction = Telerik.Web.UI.Editor.CommandList.getCallbackFunction(commandArgs, function (sender, args) {
            if (!args) {
                //alert("No args!");
                return false;
            }

            var selectedItem = args.get_value();

            var path = args.value.getAttribute("src", 2);
            var style = editor.get_contentArea().style;
            style.backgroundImage = 'url(' + path + ')';
            document.getElementById('<%=hdnBackgroundImage.ClientID %>').value = path;

        });
        editor.showDialog("backgroundImageManager", argument, callbackFunction);
        return false;
    };

We upgraded to the latest Rad tools and now get an error on "args.value.getAttribute is not a function".

What can we change to get that path value from the dialog?

Hello Chris,

The described error is thrown due to the object that is sent by the dialog. This matter should be implemented in the backgroundImageManager dialog, but I am unable to find any information regarding its implementation.

Please provide a simple demo which demonstrates the custom dialog, so that I could reproduce and investigate the issue on my end.

On a side note, I can suggest using the showExternalDialog() method, which is intended for custom dialogs. More information about its usage is available in this online example.
