Setting "Menu: False" dynamically?

[Lisa]

Hi - I have columns that I want to show in the ColumnMenu:columns or not based on a variable.  What I have right now on the column definition is " menu: false," but in some cases I do want the column to show up.  I tried making it a function, not even checking the variable yet:

                    menu: function (e)
                    {

                        return false
                    },

which doesn't work.  Is there a way to do this?

Thanks

Lisa

Hi Lisa,

It is advisable creating a separate method and call it when needed, thus the code will look more transparent and easy to be maintained.

Example:

menu: ShouldDisplay()

function ShouldDisplay(){
    if(ConditionMet){
        return true;
    }

    return false;
}

Initially, the reason the method did not work was because the column.menu property takes a boolean value and a function declaration was passed to it. To make it work, the function needs to be executed, and for that, place the round brackets to end of it. (see marked with yellow)

menu: function ()
{
    return false
}(),

You can also try the Dojo Sample for a Live demonstration.
