Please..
I want to create a grid by java code but I did not find some example to do it.
I want to insert components programmatically, but I had tried creating a row and tried to add it to the grid, but it did not work.
I tried to use getRows().appendChild, but I got null pointer exception.
Well, unfortunelly I could not figure out how can I do it.
Any ideas ?
Thanks

Hi,

the following sample should give you the idea:

Grid grid = new Grid();
grid.appendChild(new Rows());

Row row = new Row();
row.appendChild(new Label("Your Name"));
row.appendChild(new Textbox());

grid.getRows().appendChild(row);

Cheers, Maik

hai,

you can see my code.

	private void setDisplayGrid(){
		Grid mygrid = (Grid)getComponent("itemlist");
		String[][] rowgrid = new String[2][2];
		ListModel strset = null;
		rowgrid[0][0]= "a";
		rowgrid[1][0]= "b";
		strset = new SimpleListModel(rowgrid);

		if (strset != null){
			mygrid.setModel(strset);
			mygrid.setRowRenderer(new rowRenderLstItem());
		}
	}

	class rowRenderLstItem implements RowRenderer{ 
		public void render(Row row, java.lang.Object data) throws Exception {
                  new Textbox("aaa").setParent(row);				
                  new Textbox("bbb").setParent(row);				
		}


	}

Hello,
you can try button-up method instead top-down like ibsolusion said.

Example :

Label label = new Label();
Textbox textbox = new Textbox();
Row row = new Row();
Rows rows = new Rows();

label.setParent(row);
textbox.setParent(row);
row.setParent(rows);

Thanks
