DIsable Foreign Key Dropdown on edit

[Dave Hayward]

I would like to add a foreign key column to my grid and have it function when in insert mode, but not be editable afterwards. I have tried to detect this condition by using the grid's 'OnEdit' event and if the mode is "edit", access the dropdownlist control and call the disable() method.

I'm not even sure if that's the best way to approach this, but that's what I'm trying to do.

Assuming this would be workable, I've tried the following

function TemplatesGridOnEdit(e) {
    var mode = e.mode;
    var form = e.form;
    if (mode == "edit") {
        $(form).find('#SoldToDropList').data('tDropDownList').disable();
    }
}

(I am not using cell edit mode)

Unfortunately this fails with a claim that the control does not have a 'disable' function. So my question is "how can this be made to work"? Is there a better approach?

TIA

try .style("disabled", "disabled")

best way to figure out the right jquery is to evaluate the expression in the debugger Quickwatch window.

Hi,

 This is very strange as as the DropDownList has a disable method. Could you please check whether $(form).find('#SoldToDropList') returns the proper DOM element? I suspect that the selector may be wrong.
