                                    </ext:Column>

protected void NodeDbClick(object sender, DirectEventArgs e)
        {
            string id = e.ExtraParams["id"];
            string text = e.ExtraParams["text"];
            
        }

i get id and text from treepanel, but how to set id and text to the column col_kjkm?

Hi @hdsoso,

If you need to use a value/text pair you should use Mode="ValueText".
https://examples2.ext.net/#/Form/Dro...alueText_Mode/

Also I think instead of an ItemDblClick DirectEvent, you use an ItemDblClick listener and call a DropDownField's setValue method in a similar way as it is done within the CheckChange listener of the example mentioned above.

[hdsoso]

can't hold on the text value in the cell which column id is "col_kjkm" when click other cell after double click the tree item.
plz see http://screencast.com/t/qs8GWdsUB

You should defined a Renderer for the Column.

Please see the Department column here.
https://examples2.ext.net/#/GridPane...Field_Mapping/

There is a ComboBox as an Editor, but it is exactly your scenario.
