ListGrid: Restrict number of records added to it

[rajesh.vashista]

Hi,

I am working on a listgrid where I would need to restrict the number of records added to it. Lets say 100.

I have an add button which invokes startEditingNew(), where I can restrict. But on pressing the down arrow from an currently editing row, a new row is added (I am aware that this is normal behavior and we need this).

I have tried restricting from RowEditorExitHandler by getting the rowNum from event. But, if I cancel the event and prevent it from adding next row, I am not able to save changes made on the last row.

Is there any other way to handle this on the client side? Please let me know.

Thanks

I am not able to save changes made on the last row.

why you can't ?

why you can't ?

Simply put, when I cancel the editorExit event, the values entered in the grid cells are not saved (Correct behavior I guess).

However, I figured out a way to do this with the following code

listGrid.addRowEditorEnterHandler(new RowEditorEnterHandler() {
				@Override
				public void onRowEditorEnter(RowEditorEnterEvent event) {
					if (event.getRowNum() > 99) {
						SC.warn("You have exceeded the number of records allowed");
						listGrid.cancelEditing();
					}
				}
			});

Is there a more elegant way to solve this? I couldn't find any.
Something like setting ListGrid.setMaxRecords(100); would be really helpful.

Thanks

This solution seems great to me. You need to submit a request (i guess) if u wanna ask for this. But as i said, your solution seems pretty good
