Disable hyperlink if cell value null in gridview

I have a grid where columns are populated dynamically. I have a column called ID which will have hyperlink enabled and hyperlinks needs to be disabled if cells value is null or empty.

For ex: If a cell value returns 0 or null values for that ID column then I need to disable the hyperlink for those cells in that columns. The below code adds hyperlink successfully and top of it I need to check for null or 0 values in the cell.

Code:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        for (int i = 0; i < GridView1.HeaderRow.Cells.Count; i++)
        {
            string strHeaderRow = GridView1.HeaderRow.Cells[i].Text;
            if (strHeaderRow == "ID")
            {
                string strMktURL = "http://www.address.com";
                HyperLink hlColumns = AddHyperLink(e.Row.Cells[i], strMktURL);
            }
        }
    }
}

protected HyperLink AddHyperLink(TableCell cell, string strURL)
{
    HyperLink hl = new HyperLink();
    hl.Text = cell.Text;
    hl.Font.Underline = true;
    hl.Target = "_blank";
    hl.NavigateUrl = strURL;
    hl.Attributes.Add("style", "color:Black;");
    cell.Controls.Add(hl);
    return hl;
}

Please suggest how this can be achieved.

Just check for your cell value is null or empty and don't make it hyperlink. Also I will suggest to make your AddHyperLink() void, if you will not use its returned value.

UPDATE

TableCell stores its value into string Text property, so:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        string strMktURL = "http://www.address.com";
        for (int i = 0; i < GridView1.HeaderRow.Cells.Count; i++)
        {
            string strHeaderRow = GridView1.HeaderRow.Cells[i].Text;
            if (strHeaderRow == "ID")
            {
                if(!string.IsNullOrEmpty(e.Row.Cells[i].Text))
                {
                    HyperLink hlColumns = AddHyperLink(e.Row.Cells[i], strMktURL);
                }
            }
        }
    }
}
