If you want all the rows of the grid, my suggestion is to simply get the model of the grid by calling getModel method of grid, than you will have all the rows of model, than you can perform your operation and notify the change to zul.

Hey all,

I had the same problem when exporting a grid or listbox with paging to a excelsheet. I had only the first page exported and not the whole thing.

Mine solution was :

public void renderMeshElementAndExport(@ContextParam(ContextType.BINDER) Binder binder, @BindingParam("ref") MeshElement meshElement,
        @BindingParam("name") String name) {
    if (meshElement instanceof Grid) {
        ((Grid) meshElement).renderAll();
    } else if (meshElement instanceof Listbox) {
        ((Listbox) meshElement).renderAll();
    Map<String, Object> args = new HashMap<>();
    args.put("ref", meshElement);
    args.put("name", name);
    binder.postCommand("exportMeshElementToExcel", args);

Quick explication :

The renderAll() will render all the rows of the listbox or grid. The only catch is that this is done at the client side.
So as long we don't go back to the client side the element doesn't render the rows.

Then we have 2 options, we can do a echo event but with MVVM I doesn't want to interact to the eventqueue myself if not needed.

So I came up to the solution, when you post a new command from the binder, you have the same effect as echo event. (You go to client side and then come back)
So the last line for me is calling the command for exporting, but you can change that to whatever command you need.
See also how I fill the Map for the BindingParam in the new command.

Greetz chill.
