The easiest way to find out what layer or sheet you have the grid on is to hide each layer one at a time. To do this just click the layer name below menu bar on the right. It will be something like L:Background. Once clicked a window will pop up that with a list of layers. There will be three boxes to the left of the Layer Name, the box on the left is the current selected layer, the box next to that is the hide box. If you click the hide box the layer will be hidden, the box next to that is the Freeze box and this will Freeze the layer so it can't be altered. Once you find out which layer the grid is on maker sure the Freeze box is not selected. Next click the eraser tool in the far left toolbar. Now select the the grid, it will turn white and you will see at the bottom of the screen on the left Selected entities (1 picked). Then right click and select Do it from the menu.

That should delete the grid and that will work for any entity you wish to remove from the map.The easiest way to find out what layer or sheet you have the grid on is to hide each layer one at a time.
