Changing content of Cell

Hello,

I am using the layout:
var dhxLayoutData = {
parent: “wrapper”,
pattern: “3L”
};

In cell B I have a login form that calls a javascript routine to validate the login information.

If the login is correct, the content of cell B is changed sucessfully with the statement:
parent.dhxLayout.cells(“b”).attachURL(“admin.asp”);

Then I want to add a html page to cell C. So I use the statement:
parent.dhxLayout.cells(“c”).attachURL(“data.asp”);
This statement gives me an error stating that parent is null. Is there a different way of attaching a URL for cell C correctly?

Thanks

Hello,

You need to use “parent” only if you change cell’s “c” content from page, attached into cell “b”.
Please, provide complete demo.
