Create hierarchical grid dynamically
posted

Hello,

 

Is it possible to create a hierarchical grid dynamically, with an arbitrary number of Master-Detail levels?

 

Thanks,
Mike

    Hello Mike,

    Yes, you can create any number of hierarchy levels dynamically within the WebGrid. Just created the grid dynamically and add a column that has a master detail grid attached, which will allow the user to expand to the next level. Your code will look something like the following.

    //Create a grid for the level to add

    GridView secondLevelGrid = (GridView) FacesContext.getCurrentInstance().getApplication().createComponent(GridView.COMPONENT_TYPE);

     

    //Setup the secondLevelGridColumns here

     

    //Create a column that will allow user to expand to the next level

    Column masterDetailColumn = (Column) FacesContext.getCurrentInstance().getApplication().createComponent(Column.COMPONENT_TYPE);

     

    //set the master detail facet on the column

    masterDetailColumn.setMasterDetail(secondLevelGrid);

     

    //Add the column that will allow to expand to the next level to the main grid

    grid.getTemplateItems().add(masterDetailColumn);

     

    Hope this helps.

    Taz.
