The same way as it is called in navGrid

  if(  CONDITIONS ARE RIGHT){
       var mygrid = $("#mygridid")

       var rowid = mygrid.getGridParam("selrow");

      if(rowid) mygrid.editGridRow(rowid, param_for_edit);
    }else{

//Open a dialog to tell the user to select the necessary information first.

        jQuery(#myDialog).dialog('open);
    }
}   
});

Also you can use editGridRow as separate method.

How do invoke the form load method with the form automatically created by the colmodel with the parameters listed in the navGrid definition. 

Alternatively, is it possible to add a buttonclick event to one of the predefined buttons?

Here's my working example with the conditions checking removed so the code is more readable:

jQuery(grid).navButtonAdd(nav,{buttonimg:"image.gif",caption:"Add",position:"first",title:"Add", onClickButton:function(){

    if(  CONDITIONS ARE RIGHT){
        //Load the form but how ?
    }else{

//Open a dialog to tell the user to select the necessary information first.

        jQuery(#myDialog).dialog('open);
    }
}   
});

Not sure, but I think it is better to use navButtonAdd and when the user click the icon for add/edit etc you should analyze the data and do what you want.

Quick question which I just can't seem to wrap my head around solving.

I have a combo-box above my grid control that needs to be populated before add/edit/del is clicked in the grid navigation bar.

I need to be able to cancel the load event and post a dialog indicating that they choose a value first.  This would be similar to the "Select a row" dialog that occurs now but instead of requiring a row it would require a combo box outside the dialog box to not be null.

Any suggestions on where to do this ? I'm currently using the beforeShowForm event to load a number of selects which depend on the non-grid related select having a non-null value.
