    Lightbulb EditorGrid + Combobox expansion in a single click

    EditorGrid + Combobox expansion in a single click


    Hello,
    I have an editor grid with a combobox for one column. By default, it looks like in order to show the list of options in the combobox, a user has to click once to activate the editor and show the combobox, and then click again to open the combobox list so that they can select an option. I would like to have this only require a single click. My ideas are to:
    a) show the combobox on mouseover for the cells
    or
    b) auto-expand the dropdown list when the user clicks a cell to show the combobox editor

    I would prefer option (a), but are either of these possible? I have searched the forums a lot, and tried a few different ways of adding a listener to the combobox to call the expand() method after it is shown, but it did not work. Any other ideas?

    By "did not work", I mean that either nothing happened, or the combobox did not get auto-expanded and I would get a javascript error when trying to expand it manually. I saw in another post that changing the expanded status manually like this can cause problems with its internal state.

    For option b you could try:
    Code:
    editor: new Ext.grid.GridEditor(new Ext.form.ComboBox({
      ...
    }), {
      listeners: {
        startedit: function(){
          this.field.expand();
        }
      }
    })
    Option a is not really possible. The only other solution is to show editor for all fields (see my EditableGrid user extension), but that should only be used on very small grids.

    Thanks for the reply. I tried your suggestion, but it didn't seem to change the behavior -- I click once to show the dropdown, then need to click a second time to expand the dropdown list. I'm using the IconCombo class too. Would there be any issues with this?

    The following is what I have:
    Code:
    editor: new Ext.grid.GridEditor(
       ...
       new Ext.ux.IconCombo({ 
          forceSelection: true, 
          triggerAction: 'all', 
          lazyRender: true, 
          mode: 'local',
          editable: false 
          ...
       }), 
       { 
          listeners: { startedit: function(){ this.field.expand(); } } 
       }
    )
