Check whether an Object is empty or null

Question

I have a DataGridView and added a column called SellQty and a Checkbox at index 0. User has to enter int value when he selects a checkbox . If not I am showing a message to enter the value. Now the problem is I am getting the value from the SellQty cell and storing it in an object and checking whether it is null .

object SellQty = gvProductBatch.Rows[i].Cells["txtSellQty"].Value;
if(SellQty!=null)
    // do something

else 
    // ..Show message.

This works fine. But the problem is when the user enters a value and deletes it, the value stored in it is {} ie empty. I would like to know how to check an object is empty. I have googled for the same but didn't find answer to handle empty object. All results were for if object is null.

You can get the actual edited Value by using the .EditedFormattedValue

if (string.IsNullOrWhiteSpace(gvProductBatch.Rows[i].Cells["txtSellQty"].EditedFormattedValue.ToString())
{
  //Do something
}
