Please try below,

protected void grdmaster_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridFooterItem)
    {
        GridDataItem item = (GridDataItem)e.Item;

        TextBox txtdebit1 = item.FindControl("txtdebit1") as TextBox;
        TextBox txtcredit2 = item.FindControl("txtcredit2") as TextBox;

        TableCell cell = (TableCell)txtdebit1.Parent;

        CompareValidator val = new CompareValidator();
        val.ControlToCompare = txtcredit2.ID;
        val.ControlToValidate = txtdebit1.ID;
        val.Operator = ValidationCompareOperator.LessThan;
        val.Display = ValidatorDisplay.Dynamic;
        val.ErrorMessage = "Error message";
        cell.Controls.Add(val); 

    }
}
