Question

I have one DataTable like this:

Attribute          Percentage      ReferenceAmount        TaxAmount
------------       ------------     ----------------      -----------
  Sales              5.00             5000                  250
  VAT                2.00             250                   5
  Discount            0                 0                   100

I want to Bind this DataTable with one GridView.
But in the GridView, I dont want to display 0. Instead of Zero, I just want leave that cell as empty. I dont want to display any other thing if that contains Zero.
How to replace EmptyString instead of Zero in the DataTable?

Answer 1

The following GridView DataBound method will loop through every cell in the GridView and replace “0” with an empty string:

        protected void GridView1_DataBound(object sender, EventArgs e)
        {
            foreach (GridViewRow row in GridView1.Rows)
            {
                for (int i = 0; i < row.Cells.Count - 1; i++)
                {
                    if (row.Cells[i].Text == "0")
                    {
                        row.Cells[i].Text = "";
                    }
                }
            }
        }
