Answer 1

I don't know your datasource, but if you can evaluate it, do something like this:

<asp:TemplateField HeaderText="Status">
            <ItemStyle CssClass="list" />
            <ItemTemplate>
                    <%# GetBit(Eval("BlackBit"))%>
            </ItemTemplate>
</asp:TemplateField>

And code-behind:

private string GetBit(object objBit)
{
    if (Convert.ToInt32(objBit) == 1)
    {
        return "Yes";
    }
    return "No";
}

Answer 2

Do you need to iterate through a DataTable dt on each RowDatabound ?

If you do not need this could you try:

protected void gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {

                Boolean bitBlack = Convert.ToBoolean(e.Row.Cells[7].Text);
                if (bitBlack)
                {
                    e.Row.Cells[7].Text = "Yes";
                }
                else
                {
                    e.Row.Cells[7].Text = "No";
                }

        }
    }

Answer 3

You could always use the rows DataItem to get the underlying DataSource:

protected void gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        DataRow row = ((DataRowView)e.Row.DataItem).Row;
        bool isBlack = row.Field<bool>("Black");
        e.Row.Cells[7].Text = isBlack ? "Yes" : "No";
    }
}
